3. _Towson, Baltimore County._—Professor F. A. Lucas (Maryland Pliocene, Pleistocene vol., p. 163) stated that the collection of the Maryland Geological Survey contains a fine upper last molar of a mastodon found on the Ridgeley estate, at Hampton, near Towson, about 10 miles north of Baltimore. At present one can not determine the time during the Pleistocene when this tooth was part of a living creature.
4. _Lane’s Creek?, Washington County._—The writer received, in 1912, a letter from Professor A. F. Bechdolt, of Bellingham, State of Washington, in which he stated that somewhat more than 37 years before, while teaching school in Washington County, Maryland, he saw the remains of a skull of a mastodon which some negroes had unearthed in making a mill-race, but they had broken it in pieces with sledgehammers. Professor Bechdolt recollected plainly the “mammillary face” of the tooth. The locality is described as being near the Pennsylvania line, south and somewhat west of Mercersberg, Pennsylvania, among the foot-hills of North Mountain, at a place locally known as “The Corner.” It appears probable that the locality was somewhere along Lane’s Creek.
4. _Clear Spring, Washington County._—In circular No. 109, volume XIII, Johns Hopkins University, 1893, pages 26, 27, is an account of the finding of a mastodon tooth in 1863. It was discovered after a storm, lying on a pile of driftwood, in Conococheague Creek, at a point 2.5 miles south of Clear Spring, and a mile north of the entry of the creek into Potomac River. The tooth is in the collection of Johns Hopkins University.
1. _Six miles east of Williamsburg, York County._—In Godman’s Natural History (3d ed., 1860, vol. II, p. 77) mention is made of the discovery, in 1811, of remains of a mastodon along the banks of the York River, 6 miles east of Williamsburg. The account was derived from Dr. S. L. Mitchill (Med. Repos., New York, vol. XV, p. 388; Cuvier’s “Theory of the Earth,” p. 399). He had received his information from Bishop James Madison, then president of College of William and Mary, at Williamsburg. The parts found consisted of the bones of the pelvis, a thigh bone, 2 vertebræ, 2 ribs, 2 tusks, and 7 molar teeth, 4 of which were yet in a part of the jaw, probably the lower. The largest tooth is reported as weighing 7.25 pounds; the smallest between 3 and 4 pounds. It is probable that mastodon teeth in a wet condition would weigh the amount stated. Clark and Miller (Bull. IV, Virginia Geol. Surv., 1912, p. 20) refer this animal to the Pleistocene of the Talbot formation.
