1. _Elroy, Van Buren County._—In 1831 (Jour. Acad. Nat. Sci., Phila.,

ser. I, vol. VI, pp. 269–286, plates XII to XIV; 1835, Med. Phys. Res.,

pp. 319–331, plates XII to XV), Richard Harlan described a number of

bones of _Megalonyx jeffersonii_ which had been purchased for the

Academy of Natural Sciences, Philadelphia, and which he reported had

been found in “White Cave,” Kentucky. This was supposed to be situated

near Mammoth Cave. It was ascertained later that the bones had been

found in Bigbone Cave, Van Buren County, Tennessee.

The bones mentioned by Harlan had belonged to a young animal and

consisted of 5 vertebræ, a few fore-limb bones, a few hinder-limb bones,

a scapula, a rib, and a part of a molar tooth. Some of the articulating

surfaces still retained their cartilage. In the same cave were found

bones of “_Bos_” (_Bison_), “_Cervus_” (_Odocoileus?_), _Ursus_, and a

human metacarpal. These were said to have been found on the surface,

while the megalonyx bones were buried at a depth of 2 or 3 feet. The

mandible of the bear (Harlan, op. cit., p. 283) was described as

displaying appearances of antiquity equal to that of the megalonyx

bones. The sloth bones were made the basis of the name _Megalonyx

laqueatus_. In 1855 (Smithson. Contrib. Knowl., vol. VII, art. 5, p. 4),

Leidy determined that these bones belonged to _M. jeffersonii_. He wrote

that the collection consisted of one molar tooth, four dorsal vertebræ,

one lumbar, a left humerus lacking the upper epiphysis, the proximal

two-thirds of the right ulna, the right radius, the left scapula, the

distal epiphysis of the right femur, the left tibia, and the distal

epiphysis of the right tibia, a right calcaneum, two claws of a hinder

foot, and some fragments of ribs. Leidy appears to have concluded that

these bones had been those of a young animal, but that other bones in

the collection had belonged to adult individuals. He stated that they

had come from Bigbone Cave, White County. This adjoins Van Buren on the

north and possibly at that time included the latter; or Leidy may have

been mistaken. Besides the bones above mentioned, Harlan described from

this cave an ilium of _Megalonyx_ (Med. and Phys. Res., p. 334).

In 1892 (Bull. Geol. Soc. Amer., vol. III, pp. 121–123), Professor J. M.

Safford reported the discovery of some bones of a megalonyx in Bigbone

Cave. They had been met with in the bat manure at a depth of about 3

feet. The parts received by Professor Safford, and which are all

probably in Vanderbilt University, were the skull, 17 vertebræ

(including 5 sacrals), a fragment of a rib, a right scapula, a right

humerus, the two ilia, a part of the right pubis, a part of the right

ischium, and a left tibia. Safford concluded that these bones formed a

part of the same young animal that Harlan had described.

In 1897 (Proc. Amer. Philos. Soc., vol. XXXVI, pp. 36–70), Dr. H. C.

Mercer gave a detailed account of his explorations in this cave. It is

situated about a mile from the left bank of Caney Fork River, a mile

above the mouth of a confluent called Dry Branch, and at an elevation of

about 1,000 feet above sea-level. It is excavated in Carboniferous

limestone and opens into what is known as “Beech Cove.” Thomas L. Bailey

(“Resources of Tennessee,” vol. VIII, pp. 131–132) described it as being

situated 3.5 miles south of Quebeck, near the head of a hollow or cove

extending south from McElroy’s store. The latter is probably the

locality put down on the topographic sheet of the quadrangle as Elroy.

It is further said to be one branch of an extensive cave whose other

branch is known as Arch Cave. Bigbone Cave is known to extend a distance

of 3 miles. It appears that the cave had been exploited for saltpeter in

the wars of 1776, 1812, and 1863 and immense amounts of the nitrous

earth had been removed. Mercer found no bones until he had reached a

small passage at a distance of 900 feet from the entrance. Here he found

an epiphysis of a left humerus, 6 vertebræ, an astragalus, and a

calcaneum of a sloth, evidently a young animal; and he concluded that

they were probably parts of the same animal that Harlan had described

many years before; also a part of a skeleton that had been found there

in 1884, which is the one described by Safford. A remarkable feature of

the bones of the young animal found in this cave, as noted by Harlan,

Leidy, and Mercer, is the presence of some of the cartilage, some shreds

of ligaments, and a part of the horny sheath of one claw.

2. _Lookout Mountain, Hamilton County._—In 1894 (Amer. Naturalist, vol.

XXVIII, pp. 355–357), Dr. H. C. Mercer reported his work, done in 1893,

in a cave situated on Lookout Mountain, near Chattanooga, Tennessee. In

a brief report made June 4, 1896 (Dept. Amer. and Prehist. Archæol.

Univ. Penn.), Mercer stated that this cave is on the left bank of

Tennessee River, 0.25 mile below Chattanooga Creek. According to the

report last quoted, the cave earth, “with its culture layer,” was

removed by him to a distance of 58 feet from the entrance. According to

the report of 1894, this was effected by digging 4 trenches, 6 feet 10

inches wide and with a depth of 3 feet, in two cases to rock bottom.

Near the bottom of the deposit were found a jaw of _Tapirus haysii_ with

teeth, and a jaw of a small _Mylodon_, identified as such by Professor

E. D. Cope. A bone of the extinct peccary appears to have been found

higher up in the layer of refuse. In a letter received by the writer in

1919, Doctor Mercer stated that later Cope expressed some doubt

regarding the identity of the bone supposed to belong to _Mylodon_.

A further reference to this cave and its contents will be found on page

396.

3. _Memphis, Shelby County._—In 1850 (Proc. Bost. Soc. Nat. Hist., vol.

III, p. 280; Amer. Jour. Sci., ser. 2, vol. X, p. 58), Jeffries Wyman

reported that a tooth and a claw of _Megalonyx jeffersonii_ had been

found in the “diluvium” of Mississippi River at Memphis. The tooth is a

first upper molar of large size; the claw is that of the median digit.

With these were found remains of mastodon, beaver, and _Castoroides

ohioensis_.

4. _Nashville, Davidson County._—From Mr. William Edward Myer,

Nashville, Tennessee, the writer has received for examination a fragment

of a tooth of a mylodon which was found near Nashville, in sand or

gravel, along Cumberland River, beneath 30 feet of gravel. This tooth

appears to be the left lower penultimate molar of _Mylodon harlani_, but

it is in some ways different. The antero-inner face has a broad, shallow

groove, while the outer face makes a smaller angle with the inner hinder

face than in the tooth figured by Leidy.

The transverse section resembles that of the lower penultimate molar of

_M. sulcidens_ Cope (Proc. Amer. Philos. Soc., vol. XXXIV, plate X, fig.

4_a_), and somewhat the tooth regarded by Cope as the upper fourth molar

of _M. sulcidens_ (op. cit., plate XI, fig. 7). It is probable that _M.

sulcidens_ and _M. renidens_ of Cope are synonyms of _M. harlani_, as

Stock (Bull. Geol. Soc. Amer., vol. VIII, p. 331) is inclined to

believe.

The greatest length of a cross-section of the tooth found at Nashville

is 27 mm.; the greatest width 14 mm. The tooth is the property of Mr. H.

L. Ridge, of Nashville.

At the same locality have been found remains of _Equus leidyi_, _E.

complicatus_, _Mammut americanum_, a camel (_Camelops?_), a species of

deer, and some turtle bones. The deposit seems to belong to a stage not

far removed from the Aftonian.

KENTUCKY.

(Map 3.)

1. _Bigbone Lick, Boone County._—In 1831, Dr. Richard Harlan (Monthly

Amer. Jour. Geol., vol. I, p. 77, plate III, figs. 1 to 3) described a

left ramus of the lower jaw of a ground-sloth which had been brought to

New York. This jaw he referred to his _Megalonyx laqueatus_ (_M.

jeffersonii_); but it was later shown by Owen (Zool. Beagle, 1840, p.

68) to belong to _Mylodon_, and he named it _M. harlani_ in honor of Dr.

Harlan. From Cooper (Monthly Amer. Jour. Geol., vol. I, p. 172) it is

learned that this bone had formed part of the Finnell collection at

Cincinnati. So far as the present writer sees, there was nothing in

Harlan’s article to show where the jaw was discovered. In 1855

(Smithson. Contrib. Knowl., vol. VII, p. 47, plate XIV, figs. 1, 2),

Leidy further described and illustrated the specimen and stated that it

was found at Bigbone Lick. In 1903, Barnum Brown (Bull. Amer. Mus. Nat.

Hist., vol. XIX, p. 511) stated that Harlan’s specimen ought to be in

Columbia University, but it could not be found. It is more probable that

it was destroyed in a fire in the old American Museum of Natural

History.

In his report on Bigbone Lick (op. cit., p. 171), Cooper stated that he

had seen in the “Western Museum,” Cincinnati, a large humerus of a

megalonyx. Cooper further wrote that he and a companion had found at the

lick a metacarpal bone which he supposed belonged to the same animal.

The humerus was described and figured by Harlan (Jour. Acad. Nat. Sci.,

Phila., ser. 1, vol. VI, p. 277, plate XIII, fig. 10). Cooper (op. cit.,

p. 172) mentions other bones of _Megalonyx_ found at Bigbone Lick, but

some may have belonged to _Mylodon_. This is the case with the fragment

of lower jaw with 4 teeth which became the type of _Mylodon harlani_, as

above mentioned. In Princeton University there is an ungual phalanx 167

mm. long, 66 mm. high, and 43 mm. thick at the middle of the height.

This is labeled as having been found at Bigbone Lick. A list of the

species discovered at this place will be found on page 403.

2. _Bluelick Springs, Nicholas County._—In the collection made by Mr.

Thomas W. Hunter, in the sulphur spring at the place mentioned, the

writer has seen two ungual phalanges which were identified as those of

_Megalonyx jeffersonii_.

3. _Henderson, Henderson County._—A considerable part of a skeleton of

_Megalonyx jeffersonii_ was found at different times extending through

some years, about 5 or 6 miles below Henderson, in the bank of Ohio

River. This skeleton is now in the University of Indiana and was

described by Leidy in 1855 (Smithson. Contrib. Knowl., vol. VII, art.

3). This collection furnished a fine skull and lower jaw. In the same

deposits were found many horns and bones of deer. The geology of the

locality and the age of the bones will be discussed on page 405.

FINDS OF PLEISTOCENE MASTODONS IN EASTERN NORTH AMERICA.

ONTARIO.

(Map 5.)

1. _Essex County._—In 1898 (Science, n. s., vol. VII, p. 80), Dr. H. M.

Ami reported that he had exhumed some mastodon remains in this county.

The exact locality was not given. It was north of the west end of Lake

Erie. The section dug up was from 6 to 8 feet deep. At the bottom were

clay and boulders; above this were found gravel and the bones, and above

these sand, shell marl, peat, and other sands of various colors. The

remains were fragmentary.

2. _Morpeth and Highgate, Elgin County._—In 1858 (Canad. Jour. Indust.

Sci. Art, ser. 2, vol. III, p. 356), E. J. Chapman announced the

discovery of a tooth of mastodon at or near this place. He had seen a

drawing of the tooth. It appears that another man also had sent to the

journal an account of the discovery, accompanied by drawings. These

showed 5 distinct crown-ridges.

In 1891 (Geol. Mag. London, ser. 3, vol. VIII, p. 504; Brit. Assoc. Adv.

Sci., 64th meeting, 1892, p. 654), Professor J. Hoyes Panton gave an

account of the discovery of mammoth and mastodon bones at Highgate, only

a few miles north of Morpeth. These were found in a bed of marl. Some

measurements of the mastodon were given.

3. _St. Thomas, Elgin County._—In a private museum at Niagara Falls,

owned at the time by Davis Brothers, the writer saw a quite complete

lower jaw and a tusk, labeled as having been found at this place in

1856, on the farm of Isaac Barnard. The jaw had the last 3 teeth on the

right side and the last 2 on the left side. In front was a tusk about 6

inches long which appeared to be in the middle of the jaw. The upper

tusk is curved in a semicircle. Dr. J. W. Dawson (Geol. Mag. London,

ser. 1, vol. VI, 1869, p. 39) mentions this find. He stated that there

were 2 lower tusks. If this was the case the species _M. progenium_ is

indicated.

4. _London, Middlesex County._—In the article quoted above from the

Geological Magazine of London, Dr. J. W. Dawson stated that there were

in the Provincial Museum 3 mastodon molars which had been found at

London.

5. _Marburg, Norfolk County._—In 1898 (Science, n. s., vol. VII, p. 80),

Dr. H. M. Ami reported the exhumation of remains of a mastodon at some

place in this county. The skull, 25 ribs, 40 foot-bones, 2 tusks, and

many vertebræ were recovered. The remains were buried at a depth of from

only 3 to 4.5 feet. At the bottom was clay; above this, shell marl, and

sands of different colors; and above all was peat.

The writer has seen this skull in Victoria Museum, Ottawa. It is to a

considerable extent restored. It appears to have been found at or near

Marburg. A small label, somewhat injured, has the record: “West half lot

15, R V, Tp. of [?]dhouse, Norfolk Co., Ont. Ami, 1897.” The penultimate

and ultimate molars are in place. The former is 113 mm. long; the latter

is 174 mm. long, and has 4 crests and a talon. The tusks are present and

the right one is 2,230 mm. long. The skull is a large one. The width

across the rear is 760 mm.

6. _Dunnville, Haldimand County._—In 1869 (Geol. Mag. London, dec. 1,

vol. VI, pp. 38, 39), Dr. J. W. Dawson gave an account of the finding of

a mastodon, in 1868, at the place named, situated at the east end of

Lake Erie. When he reached the place a large part of the animal had

disappeared, especially the tusks. He found 7 teeth, a few vertebræ, a

few fragments of ribs, and part of the right ramus of the lower jaw.

These remains were buried in a swamp, partly embedded in a layer of fine

sand. This contained fresh-water shells of species yet living in that

region. The sand was 2.5 feet thick and rested on boulder clay. Over the

sand was 1.5 feet of black vegetable mold. He regarded it as clear that

the animal lived long after the close of the Glacial period.

7. _St. Catharines and Welland Port, Lincoln County._—At Rochester

University, New York, the writer has seen a cast of a lower jaw, labeled

as having come from the place named above. On the left side the second

and third molars are present, the former slightly worn, the hindermost

not at all. On the right side the hindermost molar is not to be seen.

The second molar is tilted up behind and lowered in front. The little

wear of the tooth is on the hinder end. It is possible that the

hindermost molar was yet in the bone and somewhat under the second one.

The ramus has a length of 400 mm.

8. _Toronto, York County._—It does not appear to be wholly certain that

the mastodon has been found at Toronto; but its occurrence there is

probable. In some of his papers Coleman has reported that its presence

was believed to be determined.

9. _Junction of Missinaibi and Moose Rivers, Algoma County._—In 1898

(Science, n. s., vol. VII, p. 80), Robert Bell reported a mastodon tooth

from the locality mentioned. It had been chopped out of a skull by an

Indian. Later Bell attempted to obtain the skull, but could not, because

of high water. A further account was given of this tooth by Bell in 1898

(Bull. Geol. Soc. Amer., vol. IX, p. 383).

CAPE BRETON ISLAND.

1. _Middle River, Victoria County._—In 1912 (Proc. Trans. Nova Scotia

Inst. Sci., vol. XIII, pp. 163–174), Mr. Harry Piers, curator of the

Provincial Museum, Halifax, presented a paper in which he detailed the

history of mastodon remains found on Cape Breton Island. At the place

above named, in a meadow, at a depth of only 5 inches, was found a right

femur. According to Piers’s account, this was discovered about the year

1834, possibly a few years earlier. It came into the possession of the

Mechanics’ Institute, at Halifax, and later of the Provincial Museum of

Halifax, where it is now preserved. It was noticed and figured by J. W.

Dawson in the four editions of his “Acadian Geology.”

2. _Baddeck, Victoria County._—According to Piers’s account, a molar

tooth of a mastodon, now in the Provincial Museum, was found in 1859, at

the place named. This tooth is figured by Dawson, with the femur. Piers

states that Dawson was in error in crediting Honeyman with the

discovery. Details regarding this are wanting. The molar has 3 crests.

In the same museum is a part of a proboscidean tusk, but it is not

certain where it was found. It is quite certain that all of these

remains are of animals which lived there after the Wisconsin ice had

retired.

These localities are not indicated on the map.

MASSACHUSETTS.

(Maps 5, 6.)

1. _Coleraine, Franklin County._—In 1872 (Amer. Jour. Sci., vol. III, p.

146), Dr. Edward Hitchcock, in a letter to one of the editors, reported

the discovery of a tooth of a mastodon at or near this place. It had

been shoveled out of a muck-bed, on the farm of Elias Bardwell. Nothing

more is known about the matter. This tooth was mentioned by B. K.

Emerson in 1917 (Bull. U. S. Geol. Surv. 597, p. 149).

2. _Shrewsbury, Worcester County._—In 1885 (Trans. N. Y. Acad. Sci.,

vol. V, pp. 14, 15), N. L. Britton read before the Academy an extract

from the New York Times, copied from the Worcester Spy of October 14,

1885, relating to the finding of a human skull near Shrewsbury, close to

the spot where mastodon remains had been found the year before. In

Science (vol. VI, 1885), Professor F. W. Putnam gave an account of the

investigations of the case made by himself and others. The conditions

under which the mastodon was buried were incidentally described. In the

same year Franklin P. Rice, a member of the Worcester Natural History

Society, published a pamphlet of 8 pages, in which the discovery and

exhumation of the remains were set forth; one molar, an upper

penultimate, was well figured. A trench was being made in a meadow of a

farmer, W. U. Maynard, about 2 miles from the center of Shrewsbury, on

the road to Northborough. The teeth and some bones of the mastodon were

met at a depth of 8 feet. Putnam stated that these remains, as well as

the human skull, were resting on blue clay beneath a bed of peat. Rice

reported that the mastodon bones and teeth were resting on bed-rock.

Putnam believed that both skulls had been transported thither by water

before the peat was laid down. From Mrs. Ella Horr, custodian of the

Natural History Museum of Worcester, the writer has learned that the

mastodon remains are preserved there. Mention was made of these remains

by B. K. Emerson in 1917 (Bull. U. S. Geol. Surv. 597, p. 149).

There is no reason to suppose that the mastodon in question lived before

the Wisconsin stage, but at its close. The ice must already have retired

beyond the State, and the land, which, according to Dr. Fairchild, was

depressed at the latitude of Shrewsbury about 350 feet, must have been

elevated enough to reduce considerably the area covered by water before

conditions would have favored the presence of mastodon. It is possible,

however, that the depression was not so great.

CONNECTICUT.

(Maps 5, 6.)

1. _Cheshire, New Haven County._—In 1828 (Amer. Jour. Sci., vol. XIV, p.

187), a note appeared which stated that in the summer of the preceding

year 3 or 4 large molar teeth of a “mammoth” had been found near

Cheshire. From the description it is evident that they were teeth of a

mastodon. They were in fine condition but were immediately destroyed in

a frolic of the workmen. The teeth had been found in gravel only a few

feet under ground. Warren (“Monogr. on _Mastodon giganteus_,” p. 3)

stated that the mastodon teeth had been found in making a canal at

Cheshire. He undoubtedly referred to the teeth mentioned above.

Schuchert (Amer. Jour. Sci., ser. 4, vol. XIV, p. 321) states that one

tooth was preserved and is now in the Yale University collection.

2. _New Britain, Hartford County._—In 1835 (Amer. Jour. Sci., vol.

XXVII, p. 165), a report was published about the finding of a vertebra

of a mastodon in digging a canal for a factory in Berlin, not far from

New Britain. It appears to have been met with in a deposit of marl.

Schuchert (op. cit., p. 322) mentions this find and says that the

locality was not in Berlin, but in New Britain. The depth is given as 3

feet and the material as mud or clay.

Schuchert, as cited, gave an account of the discovery, in 1852, of

another mastodon in New Britain. Two or three teeth and some bones were

found in a soft swampy soil.

3. _Farmington, Hartford County._—In 1914 (Amer. Jour. Sci., vol.

XXXVII, pp. 321–330), Schuchert and Lull described the exhumation of a

mastodon near the town named. All of the principal bones of the skeleton

were secured. One tusk and most of the foot-bones were missing. The

account ought to be taken by collectors as a model for their reports.

The exact position of the skeleton is given. A topographic map of the

surrounding region is furnished, as well as the details concerning the

materials occurring above and below the bones. These lay on boulder clay

of Wisconsin age and were covered by materials washed in from the

surrounding higher grounds. No mollusks were found in the excavation,

and little vegetation. The bones, as shown by Lull’s map, were

remarkably little disturbed, not more than one might expect from the

activities of wolves. One of the tusks was, however, removed from the

skull a distance of 23 feet and left on ground 2 feet higher. Schuchert

regarded this as being hard to explain. The other tusk was not found at

all.

4. _Bristol, Hartford County._—In 1885 (Trans. N. Y. Acad. Sci., vol. V,

p. 14), O. P. Hubbard stated that the remains of a mastodon had been

found at Bristol, but no further information was furnished.

5. _Sharon, Litchfield County._—In 1828 (Amer. Jour. Sci., vol. XIV, p.

187), in a footnote, it was reported that, a good many years before that

time, some remains of mastodon had been found near Sharon. In 1835

(ibid., vol. XXVII, p. 166) it was stated that a mastodon bone, found

probably at Sharon, had been presented to the museum of Yale College.

There seems to be no certainty that the bone was correctly identified.

NEW YORK.

(Maps 5, 6, 34.)

1. _New Dorp, Richmond County._—In 1901 (Ann. N. Y. Acad. Sci., vol.

XIV, p. 67), Dr. Arthur Hollick reported the discovery of some fragments

of a molar of a mastodon in a swamp deposit in the Moravian cemetery

immediately north of New Dorp, Staten Island. The molar was found at a

depth of 23 feet. The swamp, now drained, was located immediately on the

moraine of the Wisconsin ice-sheet (Folio 157, U. S. Geol. Sur.). It had

evidently at first been a pond about 25 feet deep; later it had become

filled up with sandy silt, muck, and vegetable débris. At a depth of

about 8 feet Hollick found a stratum approximately 2 feet thick, in

which were cones of white spruce (_Picea canadensis_), a tree now found

not farther south than northern New England and the Adirondacks.

Evidently the mastodon had lived there not long after the retirement of

the ice, for the tooth appears to have been only about 2 feet above the

bottom of the old pond. The spot is probably at an altitude above the

submergence described by Fairchild (Bull. Geol. Soc. Amer., vol. XXVIII,

p. 279).

2. _Ridgewood, Kings County._—In 1885 (Trans. N. Y. Acad. Sci., vol. V,

p. 15), Mr. D. S. Martin stated that some 15 or 20 years before that

time a mastodon skeleton had been exhumed in excavating for the

Ridgewood, Long Island, reservoirs. No details were furnished.

3. _Jamaica, Queens County._—In 1859 (Proc. Amer. Assoc. Adv. Sci., 12th

meeting, 1858, p. 232), J. C. Brevoort reported the finding of 5 molar

teeth and fragments of bones in removing pond-muck in the valley of a

small stream which flowed into Baisley’s pond, near Jamaica. In the pond

itself was a deposit of mud, in some places 6 feet deep, which rested on

gravel. This deposit of mud, mixed with vegetable matter, is continued

up the valley mentioned. The bones and teeth were found about 20 yards

from the channel of the stream, resting on the gravel and covered by

about 4 feet of the muck.

According to Folio 83, of the U. S. Geological Survey, Jamaica and

vicinity is situated on stratified drift which was laid down while the

foot of the glacial ice was immediately north of the town. The mastodon

must have lived there after the retreat of the ice from the island; it

may have been a long time afterward. According to Fairchild, as above

cited, this locality was submerged by the sea while the stratified

materials were being laid down.
