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. VIRGINIA. (Map 5.) 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. Dr. Lyon G. Tyler, president of College of William and Mary, informs the writer that the fossils above mentioned were doubtless destroyed in a fire which consumed the main building in 1859. 2. _City Point, Prince George County._—The U. S. National Museum (No. 539) contains a part of the upper second true molar of _Mammut americanum_, sent there in 1888 by Mr. John S. Webb. The tooth is silicified. Mr. Webb reported that the fragment had been unearthed by laborers in making a ditch through some lowland which abounded in shells and blue marl. In a letter dated September 2, 1918, Mr. Webb informed the writer that his recollection is that the tooth was found about 12 miles north of Disputanta and near James River. 3. _Abingdon, Washington County._—An upper right second true molar in the U. S. National Museum (No. 8807) is recorded as having been received in January 1869 from Mr. Wyndham Robinson, but there is no information as to the exact locality, depth, and kind of soil inclosing it. With it were found some vertebræ and fragments of ribs and of tusks.
