It now has m em bers scattered throughout the United States. and also h as many members in foreign countries. THE SOCIETY is a non.profit organiza tion of men and women interested in the study and exploration of caves and allied phenomena. It is chartere d unde r the law of the District of Columbia. Its energies are d evo ted to unlocking the truth of the world underground. THE SOCIETY serves as a central agency for the collection. preservation. and pub lication of scientific. historical. and leg endary information relating to speleology It arouses interest in the discovery of new caves and encourages the preservation of the natural beauty of all caverns. THE AFFAIRS of the Society are con trolled by a Board of Governors. The Board appoints the national officers. The Board a lso approves committee chairmen, who are chosen not only for their proved ability in a particular field. but a lso for their activity in the work of the Society.

The above description, written b y a noted Spanish traveller and explorer of the nine t eenth century is not simply another opinion. It i s a ge Ological f ac t tha t the calcareous formations of Cuba, extending throughout most of the coun try, contain impressiv e caverns which have bee n studied silice the eighteenth century, but in a systematic man ner only since 1940, when the Cuban Speleological Soci e t y was founded. Since tha t tim e, more than 1000 caves and grottoes h ave been explored, spread over the archipelago of islands which forms Cuba. Innumerabl e In dian artifacts h ave b ee n found in their r ec esses, as well as species of eyeless fish and shrimp living in underground l a kes and streams. Secondary cave form ations of impressive beauty, such as the hel ictites of B ella m a r Cave, and fossil r emains of the Cuban ple i stoce nic fauna are among othe r mate ri a l so far collected. SOME INTERESTING CUBAN CAVERN S In the Maisi region lo ca t e d in th e eastern end of the isl and, the P atana Cav e is w e ll known for the abundant fauna in its subterranean room s Dark corridors, wh e re a temperature of 104 F is found the yea r round, a r e lite rally covered with strange spiders scorpions, and l a rg e worms. To complete this picture, the cave's roof sustains thousa nds of oals which disb and as soon as they see the light from the explore r' s l amps, creating an absolute chaos in that hot inferno.

of paralle l p assages and channe ls, oriented from north to SOLI th and perpendicular to the Quemados S i erra (one of the divisions of the l arger Sierra de l os Orga nos.) There are a l so severa l superposed ga ll eries, ancient r iver b e ds whic h h ave now b ee n abandoned b y th e fluvi a l waters. These are much older tha n those through which the St Tomas River i s actua ll y flowing. It is important to point out tha t the Quemados Sierra is surrounded by s h a l e deposits, a rock whic h i s more vulnerable to erosion than the h arder calcareous rock in wh i c h the caver n s a re found. The Quemados Sierra itself rest s on a base of s h a l e As suc h it i s terme d a "klippe" or root l ess" m o untain b y Germa n geo l og i s ts. ORIGIN OF THE CAVE S ince th e publication of the studies made by Grund in 1903, and Davis in 193 0 many h y p o theses on cave formations h ave emphasized the importance of the water tabl e and its fluc tu a ti o ns. Such factors h ave, in ollr OpInIOn no strong b earing o n the origin of the St. Tomas Caverns. How the n did t h e syste m ori g in ate? Here i s a t entative explanation. T h e mountain on whic h th e caves a r e l ocated consists of hard limestone rock with numerous f aults and ex ten sive joint crac ks. These h ave fat;ilita t e d the e n try and circ ul a tion of surface waters from th e rivers in the adjoining va ll ey, which flow generally in the sa me direction as t hat of th e faults and di aclases of the mounta in. Before reaching th e lim esto n e Q u e m a do s S i erra, how eve r th e rivers flow over soft b eds of s hal e, which a r e more eas il y eroded than the h arder m o untain limeston e As a result, the softer, sup erfic i a l s hal e river bed is worn faster th a n the subterra ne a n limes ton e b e d. T h e difference in l eve l b etwee n these two bed s forces th e river to f orm a new subterranean passage, l owe r than the origin a l one, f ollowing th e openings affor d e d by the crac k s and fau lts in th e mounta in s ide. The work of so lutioneros i o n wi ll r e n ew th e forma tion of a cave rn at a lower l evel. The above process repeatedl y taking p l ace has produced a ser ies of superpose d caves ex t ending across the width of the S ierr a and co nn ecting the tw o vall eys o n either side. The e l evation of th e Que m a dos S ierra due to t ectonic forces a l so, of co u rse, i nfluenced th e formati o n process out lin e d above 4 The higher caves, s u c h as the Salon Cave, T able Cave, and Candle C ave a r e the older membe rs of the system, whil e the l ow e r ones serve as channel s through which the riv ers are now flowing. B e tw ee n these two l eve ls, there a re severa l intermediate caverns which a re inund a ted only in times of flood, when the wa t e r l evel reaches them. ONE OF THE WORLD'S G REAT CAVES ,,, T h e n we began to explore the Quemados S i erra in 1954, onl y the Salon C ave was known to the l oca l residents, since they held pic nics and outings a t the cave entra nce. The subterra n ea n river was known to ex i s t but no one had ventured to follow it into the S ierra. Many other entrances of caves which are interconnec t e d in side the Sierra h ave s ince b ee n di scovere d. In the five miles of mappe d passages so far explore d, many side ga lleries and connections h ave yet to b e explored. In a n y case, the import ance of the St. Tomas Cavern rests on the fact that it i s the longest known integ r a ted cave system south of Florida. Dammed pools interrupt navigation by rubber boot.

A TRIP TO T H E CAVER N T he trip from Hava n a is made l e i surely until we r eac h Ponce, a small vill age in the midst of the verti ca l cliff s of the Sierra d e los Organos. A je e p waits for us and in a few minutes, we are driving through the lower re ac hes of the Sierra; verdant tobacco p l anta tion s and exotic tropical vegetation surround us everywhere. Soon we reach a spot near the Quemados Sierra its e lf from where we see the dark cave entra n ces in the cliff side.

Saltpetre Mining Tools Used in Caves By BURTON FAUST Most stJeleologists ?'eali ze that caves aided th e cause of the Unit e d States in the War o f 1 8 1 2 by p roviding saltpetre, a vital ing?'edient of explosives of the time, But the ear liest recorded uses of saltpetre date back mOTe than 4000 years. In the course o f his cave studies, th e author has fitted tog ether a comprehensive jJicture of th e to o l s and methods by which the compound was extmc ted fTOm cave ear th. In geneml, fOTm follow ed function, consis tent with tool material avai l a bl e and e x is tin g t ec hnology. The mate?'ial pre sent e d clearly shows the d evelopment of th e indust?) up to a time when i t vanished as a fonn of human ac tivit y, l eaving little behind but the tools themse l ves a s one measw'e of man's jJrogress. The r ecove ry of saltpetre from th e earth of caves i s a simple operation although standardi zed procedures d eve lop e d only over a long period of time, as the result of much investigation. The study of the so urces formation, recov e ry, purification, and uses of saltpetre occupied the attention of a numbe r of the ea rly chemists and eve n some alchemists, among whom were :Nlar ccllin Pi erre Eugene Bertholet1 Antoi ne Laur ent L avo i sier2 Roger Baco n3 Georgius Agri cola4, John BateS, 'l\1illiam Cl arke6 and H enry Stubbe?, to name a few The b eginnings o f the utijization of saltpe tre a re shrouded in antiquity. The earliest uses ap p ea r to b e as a diure tic, a carminative, a r e frig erative, a meat prese rv a tiv e, and an antiputrifactive or embalming material. These date to around 2 100 B.c. and are re corded on ancient clay t a bl e t s r ecently unearthe d in the country of the Sumarians8 They tell the story of the production, r ecov ery, and of these uses of saltpetre. In the r ec overy operations, the basic physical c h emica l theory invol ve d follows clos e l y the law of differ ential solution. In eff ect, this i s the recognition and utilization of the different solubility factors of diff erent sa lts in diff e r ent temperatures. In its simpl est form the method of recov ering saltpetre from the cave earth and refining it for use comprises the following steps: 8 1. Plac in g the cave earth in tubs, barrels, or vats and cover in g th e m a teri a l with wat e r. 2. Allowing the mud, thus formed, to stand for one to thre e d ays during which time the calcium nitra te i s l eached and dis solved by the wa ter. 3. Draining the solution from the container. 4 Treating the l each-brine, thus obtained, with potash that was usually procured by leaching wood-ashes in a similar manner: (This operation changed the calcium nitrate to potash nitrate and caused the precipitation of the calcium as an hydroxide). 5 Boiling the solution of potash nitrate to increase the concentration by evaporating part of the water. 6. Separating by partial crystallization the common salt and other minerals that are less so luble in water. 7 Decanting the hot supernatent liquid which contains the greater percent of pot ash nitrate. S. Allowing the hot liquid to cool which will cause much of the potash nitrate in solution to precipitate. 9 Redissol ving the recovered crysta l s in a sma ller vo lume and recrystallizing the potash nitrate after which the c rysta l s are w ashed with cold water; or, (9). Mel tin g the crystal in a pot ov e r a fire and removing the scum th a t forms on the m e l t e d material; the n 10. Pouring the m elte d material into a container in which it will coo l into a hardened partly-crystallized chunk. This last step provided a material known as grough-saltpetre which was generally shipped to THE NATIONAL SPELEOLOGICAL SOCIETY

the powder factory for further treatment. Man uses too l s to produce any substance. The m a t e rial avai lable of which such implements are constructed and the us e for which they are employe d will condition th eir form Since saltpetre miners and refin e rs were no exception to this general statement, l e t us consider some of the tools and equipment utilized to produce a usable sal tpe tre from the earth of caves. One general observation can b e made at th e outset: Most of the tool s and other equipment us e d were made of wood. There was limited use of metal tools, evide nced b y existing pick-marks and what appear to be scraper-tracks and spade or shovel-traces. Howeve r very few m e tal tools have b ee n found in any of the caves. Probably at l east two reasons account [or this situation. First, metal was scarce, hard to obtain, and the r efo re expensive. Second, the few metal tools available were precious, s inc e they could b e used [or m a ny jobs for which wood tools we r e not sati sfac tory. Therefore it i s re asonable to assume that the miners took their m eta l too l s with the m when they left the cave. There is possibl y a third, although minor, r easo n. Metal too l s make a h arsh, gra ting, and dis co n certi ng racket when scraped along rough rocks and stones. Before any digging or mining in a cave was pos s ible, it was n ecessa r y to have light. Extant evidence indicates that th e most commonly used light-source was flaming fat-pine faggots; how ever, it seems safe to assume that Aambeau or some other forms of torc he s were us e d. It was known practice to soak drie d cat-tail h ea d s in animal fat or pine pitc h [or us e as torches. It was known procedure, by the Indians at l east, to cut sections of hollow p lant s talk s or reeds fill the hollow portions with melted animal fat which h ardened upon cooling, and thus pro\"ide a combined wick and source of fuel. So m e times bound bundles of oat-suaw were u sed. Spectro scopic study of certain black depos it s from sa ltpetre sections o[ C l a rk 's Cave indica t e that these deposits a r e organi c in nature It i s l ogica l to conclude that soot [rom torc hes and other lights constitutes a t l east a part of th e samples that have been analyzed. "Vhile ex i sting condition in a parti cular cave were determining [actors in the equipment the mine rs used, the ba s i c tools remained similar and rather uniform 111 t ype throughout the BULLETIN NUMBER 17, DECEMBER] 955 whole industry 1 the passag e s in which the de posits were loc a ted w e re large in compari so n with the size and h e i ght of a man, and the petredirt was friable and loose a shovel was abou t all that was nece ssa ry in th e mining operation. However, if the p assages were small, low, and narrow, the mine rs were forced to use other tools. In such cases, wooden paddles ranging from the size of a m a n 's h and, h aving a handle portion t e n to twelve inc hes long to some of approxima tely t e n b y 1 2 in c hes in size with a handle portion about two feet long, were commonly used. Many collected sa mples show con siderable d eviation from thes e dime n s ions. Such differ e nces appear to have b ee n l argely the result of personal taste. Observations indica t e that paddles of va rious sizes and s h apes were used to scr ape th e p e tredirt from l e dge s and cracks in which the ma t e ri a l was lodge d. 1 available paddles were too l arge [or particular spo ts, it was not uncommon for the miners to u se l o ngshanke d chiselpointed scraping and diggin g st i cks, a n inch to an inch and a h a lf in diame ter and from s ix to 30 inches in l ength.

Sieves constructed in a variety of forms were used to remove th e smaller rocks. Some were rectangular, ranging in size from one to two feet in width and two to four feet long and three to six inches in depth. Others were roughly cylindrical or bucket-shape d in form, four to s ix in ches d ee p and 16 to 24 inc hes across the top, and had hand-holds ad jace n t to the top. The bottom, or the screen portion, was made b y interlacing wires across th e opening or by punching holes in a flat piece of sheet metal, thus making a collander-like bottom. Either form would retain the rocks and allow th e finer material to pass. There is much evidence of extensive us e of s ieves in Clark's Cave. ''''hen it was not possible to us e animal-drawn carts or cars to move the petre-dirt to the proces sing point, it was n ecessary to use other means. From all evid e nce observed, the miners carried the dirt in bags slung across a shoulder, or dragge d them through the crawlw ays These bags were generally s imil a r to the present day burlap, jute, or gunny sac k. Another extremely interesting and unusual piece of equipment u se d by th e "Petre-monkeys", in th e possession of th e writer, i s what may b e called a bag-holder. This particular sample re sembles a stirrup in form. It is made of a flat sided, rounded-edged piece of wood nine inches long, one and one-fourth inc hes wide, and three fourths of an in c h thi ck .. In eac h end and in the bottom, metal prongs have been driven. Over the top, a U s h a p e d rounded, and smoothed piece of wood has been arched. Adjacent to the ends of the fla t-sid e d piece, holes have be e n bore d. Into eac h one of these holes one end of the U-shaped a r c h has be e n inserted and fast ene d Thus a triangular isosceles-shaped struc ture i s obtained with the crotch angle rounded. Apparently this tool was u sed by plac in g a bag on the ground; inserting the tool within the mouth of the bag; hooking the prongs into the meshes of the bag adjacent to its mouth; stretching the bag over and around the a r c h e d top; holding the bag and tool in one h and; thu holding open the mouth of th e bag into which the p etre-dirt could be pushed. Now and the n it was n ecessa r y to lift th e petre dirt fr0111 pits. Under such conditions, it was a practice to provide a winch. Sometimes thi was BULLETIN NUMBER 17, DECEMBER 1955 done by constructing a log frame, similar to a saw-buck, over the mouth of the pit. A smoothed wood cylinder, of uniform diameter and longer than the distance betwee n the side frames, was mounte d horizontally betwee n the support legs and above their intersect ions. The cylinder was supported on bearing blocks and h eld directly over the pit. Crank-handles were fixed on each end of the horizontal log A rope fastened to the cylinder would wind in a spiral around its circumference as the cylinder was rotated, thus lifting a load to the surface. Occ asionally, the s upport frame was modified and the horizontal cylinder was supported on vertical bearing blocks which were held in a n upright position by angle braces. Tally-marks records a re found in many petredirt pits. In the case of deep excavations, differ ent sets of m a rks may be see n at different e l eva tions above the ex i sti n g floor apparently because these marks were made as the excavation pro gressed The significance of s uch records is not clear, but they probably represent units, possibly bags, of petre-dirt remove d from the particular pit. Since muc h p etre-dirt was found in pits and consequently not readil y accessible, steps or lad ders were built to reach the d epos its. In case the s lope along the work route was not over 45 flat stones were used for s teps An excellent example of stone s t eps i s found in Buchanan Cave. If the pit walls were to o steep for steps, the n various forms of ladders were us e d Probably the simplest form was made by tak ing a log t e n to 12 in c hes in diameter and notching s t eps into one side. The steps were cut at s u c h a n a n g le tha t when the log was placed in position, the step-treads would be approximately l evel. Thi log-t y p e of ladder generally was the most practical to u se in ascending or descending steep, smal l openings. One use of this form is found in the Big Bone and Arch Caves system. nother form of single-pole ladde r was made b augering holes through a log along a longitudinal line and driving pegs into the holes so they extended on both sides of the log. Thus a tre e-like ladder was formed up which the men could climb b y stepping from one peg to the next on opposite sides of the support pole. A ladder of this type was found in Sinnet Cave. 11

PAGE 14

Photo by Burton Faust One form of ladder found in Trout Cave. A slightly diff erent form was shaped very sim ilarly to a wish-bone. This t ype was made by splitting a sapling, about four to five inches in diameter, from one end to within a foot of the other, and spreading the split end apart. Cross pieces were fastened betwe e n the split portion to provide steps. Thus a ladder with a sing l e pole at the top and a substantial double support at the bottom was available. This t y p e served admirably to provide an access to a narrow crac k in an uppe r part of a passage. A ladder of this type was found in Madison's Cave. Other ladders w e re similar to present day forms. These l adders comprised straight, strong uprights through which matching hol e s were auge red. A number of smaller pieces of wood, equal in number to th e number of pairs of holes in the uprights were prepared b y whittlin g their ends so they would giv e a tight fit when driven into the holes. Thus by means of a pair of up rights and a numbe r of crossp i eces for rungs, a ladder was readily made There wa s co nsiderable range in the l e n ghts of the se l adders. The writer has s een some as s hort as five feet and as long as 20 f eet. These wer e generall y co n structed so they 12 could be easily dismantled into their component parts and moved through narrow passag e s and reassembled at a new location. Probably the most elaborate form of ladder and one of the best examples of workmanship is illustrated in a specimen found in Great Salt Petre Pits in Tennessee. This particular type was made by squaring one side of eac h of two logs about ten inches in diameter and approximately 35 feet long; cutting slots abollt two in ches wide and at a predetermined angle in the squared faces (in the example mentioned, the slots measure 13 and one-half inches on ce nters) ; providing pieces of planks about two feet long that would slide into the notches ; augered t woinch holes completel y through the logs about every ten feet of their lengths; moving the dis assembled logs and planks to the desired location in the cave; assembling the ladder by spac ing the l ogs in an upright position the necessary distance apart with the slots approximately lev e l; sliding the plank-ends into their matching s l ots; inserting the round crosspieces into the augered holes; and pinning them in p l ace to prevent the log s from spreading and to hold the component parts in assembled relation. Thus a form of step-ladder was made for places where a permanent installation was needed for heavy traffic. These were the typical forms of ladde rs. Com binations of the b as ic forms were used and lo ca l conditions necessitated considerable variation in installations. One inte r est in g general observation may be made as evidenced by inspection of many differ ent ladde rs and installations in many different caves: the more e labroate the design, the better the workmanshi p, and the bette r the state of preservation.

If it wer e ,not possible or practical to fill the pit w ith rocks and provide a wa l kway, it was a common prac tice to construct bridges. In some instances. a bridge was built by the use of one or more logs to form a stringer construction to support a plank over which the miners could wa l k Some times, if the plank were laid on an angl e, cleats were fastened to the top surface to provide foot holds to keep the men from slipping. On occa sions it was necessary to build an elaborate trestle-work structure to provide support for walkways In a discussion of wa l kways as well as ladders, few general statements can be made since t l e means employed and the practices fol l owed were governed by local conditions. All extant evidence indicates that everything possi-ble was done to ease the lot of the miners in the salt-petre caves In some instances, the cave entrances were suf ficiently close to the depos its that the men could carry the petre-dirt directl y to the processing point. In o ther instances, the caves were too high BULLETIN NUMBER 17, DECEMBER 1955 in the mountains and the approach slopes too steep to make such a means of transportation practical. At l ocations such as Clark's Cave and Trout Cave, another expedient was utilized A chute or trough extending from the cave en trance down the steep slope to a lower elevation was constructed. The petre-dirt was dumped in to the trough at the cave entrance, where it ro lled or slid down the hill to a supply heap for the pwcessors. Sometimes it was necessary to push or drag the dirt to keep it movingB Photo by Burton Faust Slab rock steps along a miner's path in Buckhannon Cave. After the petre-dirt had been m ined and transported to the recovery plant, entirely dif ferent types of equipment were used. Major Raines, in his "Notes", lists t h e "Arti cles wanted to make saltpetre on a sma ll scale." One ordinary imn pot for boiling; three or fowtubs, pails or ban'els cut off; two m thee small tmughs; some coane bags or a wheel ban-ow to b1'ing the earth fmm the cave and four stmng barrels with one head in each-empty vinegar whiskey, or pork ban' els m'e very good-are about all the arti cles required fOl' a small saltpet1 e manufac tmy.

The halfl og was grooved and hollowed along its center [rom one end to about a foo t from the other, thus forming a trough with one end open. This trough was centered parallel to the l o n g ax i s of the rec ta n g l e and h eld b y flat rocks abou t a foot above the ground with the closed end a f ew in ches hig h e r than th e open endc Next boardsD were placed with their lower ends resting within the groove of the trou g h and their upper ends l eaning against the top rail of the l o nger side of the r ectangular frame.

A l ayer of twig s with a covering of straw was re a dy to use Other forms of leachingvats were used, only one of which is d escribed here. This type was constructed in a manner similar to the follow ing: A proper foundation was prepared on wh ich was p l aced a series of parallel strong l ogs about a foot above t h e ground. From front to back, th ese parallel l ogs were successively higher. Halflogs with rounded troughl ike grooves cut in their plane surfaces in a longitudinal direc tion were l aid in close parallel ism across the tops of the support l ogs A second l ayer of half-logs grooved in a like manner, was laid with the grooved faces down, spanning the edges of the lower layer. The two l ayers of grooved half-logs formed a s loping, tight, rectangular platform or bottom in which t h e lower layer served as drai ns and the top l ayer as closures and guides for fluid. Sides which were usually from three to five feet high were constructed above and within the confines of this platform or bottom. This pro d u ced a l arge capac i ty leaching vat such as was us ed in Mammoth Cave and the Big Bone-Arch C aves system. Photo by Roy Davis Collecting trough mode by hollowing log Since iajor Raines recommended that the amount of water us e d to leach the cave-earth be k ept to a minimum "otherwise there will be much time and fu e l lo s t in useless boiling of a weak liquor; this is a common error at the caves, and causes the saltpet re to cost more than is neces sary in time, l abor and fuel,"9 the leach-brine was made to p ercolate through three or four l eac h-vats so it could become more thoroughly saturated with the calcium nitrate, before fur ther treatment. This was accomplished in vari-16 ous ways. Someti mes, the leach-brine that had b ee n collected in watertight troughs, vats, or tubs was transferred to the next leaching-v a t in buckets. Sometimes th e vats were located in a cascade pla n and the leach-brine that draine d from the bottom of one vat would flow to the top of the next vat. An installation of this type was used in Buchana n Cave Evidence has bee n discover e d that pumps similar to the Co lonial fire pump were used Photo by Russell T .Nevilie TOP-One hollowed log pipe line brought water into cove; the oth e r conducted leach-brine from the cove. BOTTOM-Joint i n wood pipe line. Note metal bond reinforcement. On occasions it was more convenient to locate the leaching-vats in the cave in close proximity to the petre-dirt deposits. When that was done, the water was often brought into the cave through a pipe line and the leach-brine pumped to the surface to the boi ling kettles. The r emains of such installa tions can be seen in Mammoth Cav e and in the Big Bone-Arch Caves systems When water was ava ilable in the cave, it was carried to the leaching vats Occasiona ll y a dam was constructed across a cave stream and suffi cient h ea d produced that the water could be car ried to the l ea ching-vats in a flume. The ruins of such an installation a re found in Tony's C ave. THE NATIONAL SPELEOLOGICAL SOCIETY

As we advanced i n this chamber we found these singular sen .wtions to increase in intensity until it be ,came almost unbeamble. We ventw'ed on still farthel', howevel', though it became evi dent that we cou ld not long remain in this mysterious place. I omitted to mention that the wa lls and flo01' of this chamber, espe cially TOcks thel'ein contained, were highly magnetic, and became 11Wl'e so the further we advanced towm'd the north; one of the party who calTied a hatchet had it suddenly wl ested from him by a magnetic TOch near which he passed, and the combined stl 'ength of four of us was insufficient to detach it. A pocket-knife, which accidentally dTOpped to th e flo01', had to remain there, none of the party having suffic ient stl'ength in his fingers to pick it up. Mason, who had jJUt on for the occasion a pail' of miners' boots, the soles of which we1' e filled with nails, could walk with difficulty, and hajJPening to s tep upon a pm'tion of the floor unusually mag netic, found himself suddenly affixed there to, a.nd unable to move. He was compelled to wilhdmw his feet fmm his boots and leave them thel'e (15. No SUCH ORE EXISTS, AND UNTIL RECENT YEARS, EVEN ELECTRO-MAGNETS OF SUCH STRENGTH DID NOT EXIST) tem 'ing up his coat and wrapping the pieces aTOund his feet to protec t them fTOm being cut by the TOcks. Jl'e had 1'emained in this chamber about ten minutes w hen suddenly the chill ing sensation began to increase, the feeling b eing as if a cold and jJie1'cing wind was blowing upon us and becoming each mo22 ment 1 / w r e intensel y cold. We hastily re tl'eated and soon reached, feeling 17W1'e dead than alive, the larg e chamber containing the hot sp1'ing. We then l'etmced our steps along the twine, and in a coupl e of hours emerge d fTOm the cave. J;T1 e examined the sujJIJosed hieTOglyphic chamcters mentioned in your paper of the 6th inst., and (/.1'e of the opinion that they are not artificial but have been formed by the action of water trichling over the face of the roch. The description of the magnetic chambel' given you above is true in every jJal, ticular and each one of the party will vouch for it. We we1'e none of us ex cited 01' frightened until just before our exit fTOm the c hamber, notwithstanding the stul11ge and myste1'ious phenomena we ll cal culated to make us so.

Mackinac Island Caves-The caves on Mac ki nac Island probably boast of more "swanky" vis itors than any other cave Being easy of access, with good paths leading to them, the caves are ,inspected by many summer vacation i s t s and cas u a l tourists. Mackinac Island i s formed of a breccia limestone-an. old limestone undermined by g iant caverns that ultimatel y collapsed form ,ing huge masses of broken rock (breccia) which in turn was recemented as a lim estone The caves are not true solution caves but were de veloped by wave action of g l ac i a l l akes that were predecessors of our present Great Lakes. Scotts cave is on the northeast side of the island near St. Clair Point. It is 145 feet above Lake Huron and is a result of wave erosion of Lake Nipissing. The cave is 15 feet l ong, 8 to 10 feet wide, and 9 feet high. Sku ll cave, located at the south end of the island, 2000 feet north of Fort Mackinac, is s im ilar to Scotts cave It is 226 feet above Lake Hu ron and was developed on the former shore of Lake A lgonquin. The cave received its name in co lonial days when Mackinac Island was an im portant Bri tish ou tpost. A lexander Henry, I a fur trader, fled to Mackinac Island during Pon tiac's Conspiracy and was hidden in the cave for the night by friendly Indians. Henry awoke the 'next morning -to find his bed had been of human bones. The second night he chose to sleep in a nearby bush. On the return of friendl y Indians he questioned them concerning the bones but a ll professed ignorance of them. It is possible the bones may be from a ncient people w h o inhab ited the area before the time of Indians.' Other sma ll sea caves on the island are Echo Grotto, Cave of the 'Winds, and Eagle Point Cave Numerous sea arches, of which Arch Rock with a span of 80 feet is the most spec tacular, a re a result of cavern development by wave action followed by intensive erosion l eav ing onl y the arch. Sl. Ignace Cav e-A small solution caye lies in the bluff above Graham Street in St. Ignace.

Two caves have been reported near Trout Junctio n in the Upper Peninsula' One of these was reported to be a natural bridge a t Trout .J unction. A road crossed the bridge and on each side were deep sinks with passages leading off. T h e passages were high enough to wa lk in, were 20 feet wide and a stream flowed in. A few hundred feet in the water was waist deep. The other cave was a l ow, stream cut channel 5 to 8 feet high with a Y shaped plan. At the end of the passage the stream plunged to a pool at the base of a shaft. Inquiry in 1 955 at Trout Lake revea led that residen ts of the town have no kn ow l edge of these caves and it is doubtful that they are now accessible. Fig. 4.

Sea Caves-At numerous points a lon g Lakes Huron, Mic higan, and Superior sea caves have been excavated by wave act ion In th e Lower Peninsula the l argest are at Pointe aux Barques on the south shore of Sag in aw Bay at its junct ion with Lake Huron. Here, in the Marshall sandstone, passages up to 20 feet wide and 6 to 8 feet high, form a maze extending several hundred feet. The caves are at l ake l eve l and a boat is necessary to explore them.

Sinkho les, di sappearing lakes, and solution fissures of giant sca l e more than make up for th e l ack of interesting caves. Sinkh o les-Though relativel y few in number sinkholes are of s p ec t ac ular size. They are best developed in two wid e l y separated areas. In the so u t h ea st corner o f the State a belt of s inks in Uppe r Siluria n lim esto nes ex tends from near the Ohio lin e at Ottawa L a k e north and curving to the east to Lulu in central Monroe County. The sinks are l arge, broad d e pressions up to a half mile long and a quarte r of a mile broa d.

A Proposed Classifiuation of Physiual Features Found in Caves By WILLIAM R. HALLIDAY Sil1ce speleology is a compamtivel-y ) lotl11g science, it a cquires a g1"OWi17g vocabula1y of terms unique to it.

Box work is not uncommonly grouped with secon dary spe l ea n d epos its whereas it is of entirely diff e r ent origin and significance ( I ) Many other examples immediately spring to th e mind of the spe l eo logist. An excellent b eginning in improving this sit uation was made in 1952 by George ,,,T Moore (2) who proposed the su bsti tu tion of the term spel eothem [or cave fonnation in its sense of secondary mineral deposit. Today, this is widel y accepted in speleological usage A second step was th e introduc tion, in 1 953, of the term sjJeleogen (3) to d escribe phenom ena cause d by removal o[ mate rial by solution or co nasion in lim esto ne caves \ Vhi l e a notable co n cept, the initia l definition of the t erm has apparently not proven satisfactori l y oriented for general accepta n ce, In this paper, it is proposed that the following bas i c classification of physic a l cave phenomena be co n s id ere d [or general u se : 32 I.

Experimental PmceduTe The objectives of the "vork were kept simple, to find out whether radio frequency energy (just above the broadcast band) would penetrate the earth deeply enough with sufficient strength to be useful for prospecting, and to secure any other information possible. The knowledge that radio energy would pene trate to the Left Hand Tunnel aided the plan ning. The general plan was to set up transmit ters on the surface and to measure the signal strength underground. No effort was made to g e t absolute values; that is, the primary concern was in the relative values of the signals a t vari ous points on each run. Anything done to a transmitte r on the surface might change the sig nal at any point underground, but all the other signa l s would be expected to change propor tionally. Two transmitters were available: number 1, which had about 15 watts output, and number TI .... S .OTT[II '05,TlO L OOYII) 2, which had less th a n y! watt output, operating at 1700 and 1614 kc. respectively. (An ordinary 2-cell flashlight uses about % watt of electrical energy.) The antennas were insulated wires laid on the ground. These antennas were directional in the air; it was planned to change orien tations of the an tennas and to note the effects under ground. The associated receivers had loop anten nas, by use of which the transmitter direction could be determined. The receivers were equipped with meters for showing the numerical signal strength, and with headphone s for the very weak signals which did not register on the meter. Six surface and one underground transmitter locations were used, with one 'Or both transmit ters at each location, and with different antenna orientations, for a total of 18 runs. The locations are shown on Figure 2, a map of the Left Hand Tunnel. \1\1' w a s the underground location, 'Of which more will be said later.

It i s at once apparent that the line drawn repre s ents the major portion of th e data fairly well. There h a s b ee n much discussion concerning the points which lie betwe e n 1100 and 3 000 feet. It may b e d emonstrate d qualita tively with a high d e gree of certainty that these s ignals rived in the Left Hand Tunne l from almost d I r ec tly overhead, that is, the radio signal moving over the surface of th e earth los t energy downward to give these e ffects. It i s this which p e r mits one to receive a dist ant r adio station in a cave These more t echni ca l aspects of the work have been treate d a t l ength e l sewhere. For the present 38 article it is of more interest to comment on other features of the work. The question has been asked, why not use a more pow erful transmitter and hence get greate r range? It is easily shown from the working equation that to obtain the same signal at 2000 feet as was received at 1000 f ee t would require 6000 -times as much power as was us e d. This was not feasible. It was anticipated t hat the objection might be raised that the radio signals which were receiv e d had "leaked in" through the cave mouth or by way of wiring. To forestall such criticism, tra verses were made through -the atural Entrance and in the Lunch Room, and the wiring was carefully checked, with the result that no signal leakage was found. To make doubly sure, the number 2 transmitter was set up at \iV, underground, and a regular traverse was made down the Left Hand Tunnel. The signal went from saturation value at station 58 to essenti a lly zero THE NATIO TAL SPELEOLOGICAL SOCIETY

at station 68, as shown in Figure 5. This constituted proof that there was not enough leakage to affect the results in the middle part of the Left Hand Tunnel, since its presence would have been evidenced by the high values near W. This point is of particular interest to speleo logists. It demonstrates that communications might be established between explorers separated 1500 feet or more in a cave. At the same time it should be stressed that more distance might have been obtained had the antenna been rotated 90 (The properties of this antenna are apparently not the same underground that they are on the surface of the earth.) It was found to be possible to maintain sur facecave two-way code communication s at horizontal distances in excess of 1500 feet, using the low powered transmitter in the cave. The best transmission point tried was station 64, where there was a pool of water. The underground transmitter was operated into various antennas; the simplest bu t most inefficient arrangement was connection to two ground sta kes five feet apart. Under conditions such as ex ist at Carlsbad Caverns, a transmitter and receiver the size of a cigar box could be used by exploration parties to maintain comumnications with the surface. No special radio circuits would be required, except that there should be adequate provision in the final stage of the transmi tter to match into whatever antenna system is used. An antenna laid on the ground is quite different, electrically, from the same antenna in the air. A good ground is a primary requirement. Either long-wire or loop antennas may be used on the receiver. The progress of exploration parties could be follo wed on the surface by simpl e triangulation means. As a guess, it is estimated that positions might be plotted with an accuracy of 10% of the depth. It was found that the signals received in the cave increased in strength markedly toward the end of the Left Hand Tunnel. -"Vith the number 1 transmitter at K, the signa l at 90B (Straddle Alley) was 5 to 10 times greater than expected.

The procedure was much the same as -that employed at Carlsba d Caverns but the results were not so spectacular. Tra nsmissions through a minimum earth cover of 3 0 to 50 feet were effec ted in th e vicinity of Olives' Bower (where cedar tree roots were note d hanging among some stalactites) and the Mush room Beds in Audubon Avenue, which branches from Little Bat Avenue.

The hole proved to eliminate handily the 16 foot climb, so we named it Phinizy's Relief in honor of its discoverer. "\IVe traveled in the top of a muddy canyon and arrived at Camp Pit, our advance base for explorations in this new area. The telephone wire terminated h ere, and a stockpi le of food lay against the wall. The pit itself was about 60 f ee t high and 30 feet in diameter, with a pool of drinking water in one corner.

Note new phone line under Austin's left arm. Austin, Jones, Halmi, and I joked back and forth as our coffee heated. Phinizy, sprawl ed full length on a mud bank, said he didn't see anything so funny about cave exploring in general nor about Camp Pit in particular. The man who would explain "cave humor" to a novice has no chance of b eing understood, as we soon discov ere d. 44 ''''e didn't tell Phin what was around the next bend; Bill told Halmi to bring flash powder for "something big", but Bob had scorned the idea. Now we stood at the Over look a balcony opening into an enormous pit. The balcony is about 70 feet from the bottom and probably 100 feet from the top. The pit is a perfect cylinder, about 40 feet in diameter, with smooth gray walls marred only by prominent bedding pla nes. A waterfall cascaded in visib l y from its gloomy top, and sp lashed below sti ll unseen. Rocks thrown into the abyss plunged into a deep body of water below, and sounds of waves lapping a rocky beach continued for a few seconds afterward. Phinizy whistled in awe. Halmi muttered an epithet, admitting the pit was too big to be photographed with his e lectronic flash equipment. Austin and Phil Smith had discovered it and the wonders that lay b eyond on Thanksgiving, 1954. T h e route l ay through a muddy passage on the opposite side of the balcony. One by one we climbed down into Storm Sewer, a canyon passag e that l e d onward. The floor was firm mud for the most part, but while we could walk most of the time, we had to drop on hands and knees near the end of the passage where it entered Eyeless F ish Trail in much the same manner as B Trail enters the Lost Passage. It had taken us seven hours to reach this poin-t, and now work could begin. Bill suggested that we dye the stream first, so we moved down a mud slope and turned a corner. Pools of deep, green water bracketed the route, and s li ck mud underfoot made travel treacherous. I hoisted the surplus 30 caliber ammunition box to the othe r shoulder. Bill had given it to me at the head of Storm Sewer; it contained our survey equipment and his camera. The others moved down a steep slope, over a mud bridge a foot wide between the pools, and up a mud slope on the other side It didn't look difficult, but it did look dan gerous, and with the heavy ammunition box on my shoulder I thought it would be safer to cross the bridge on hands and knees rather than risk standing up. I moved out, eyeing the bridge and the two pools; the one to niy left was abou t four feet in diameter, the one on my right was a kidney-shaped pool about THE NATIONAL SPELEOLOGICAL SOCIETY
