1. _Kingsport, Sullivan County._—The writer was informed by Mr. George P. Torbett, a newspaper man, that D. M. Lafitte, of Bristol, Tennessee, had a tooth of a mastodon, found near Kingsport. Mr. Torbett had seen the tooth and recognized its similarity to a mastodon tooth shown him. 2. _St. Clair, Hawkins County._—Dr. S. W. McCallie, State Geologist of Georgia, waiting in 1892 (Science, vol. XX, p. 333), reported that a mastodon tooth had been found somewhere in that county. On making inquiry of Dr. McCallie the writer received the information that the tooth was found about 3.5 miles nearly due east from St. Clair and about 7 or 8 miles south of Rogersville. The tooth was presented to the University of Tennessee. 3. _Mossy Creek, Jefferson County._—The writer has received from Mr. W. C. Bayless the information that a mastodon tooth had been found 3 miles south of the place named. The more exact locality is given as the farm of John Silver, 0.75 mile north of Bays Mountain. The tooth was discovered under a white oak stump, at a depth of 6 feet. It was 7.5 inches long and had 5 cross-crests. 4. _Dandridge, Jefferson County._—The geologist G. Troost, writing in 1835 (Trans. Geol. Soc. Pa., vol. I, p. 142), stated that he had in his cabinet a tooth of a mastodon from the locality named. 5. _Neuberts Springs, 7 miles Southeast of Knoxville._—Doctor McCallie, as cited above, reported the discovery of four molars of a mastodon in a fair state of preservation at a point 7 miles southeast of Knoxville. They were found beneath 30 inches of a yellow tenacious clay, in which occurred water-worn stones. In a communication to the writer, Dr. McCallie indicates that the remains had been buried at a time when Tennessee River flowed at a higher level than at present. 6. _Eleven miles West of Nashville, Davidson County._—From Mr. William A. Nelson, a member of the Tennessee Geological Survey, the information has been received that some mastodon remains, including teeth, had been found 11 miles west of Nashville, just west of Mill Creek and about 200 yards from Cumberland River. The remains occurred in a very tough yellowish clay which occupied a solution channel in the Carter Creek limestone. This was at a depth of about 15 feet from the surface.
