Wythe County at that time occupied far more territory than at present, and possibly the bones described by Madison had really been found in Washington or Smyth Counties; but Saltville, as the writer is informed by Mr. E. C. Hutton, surveyor, never was in Wythe County.
5. _Covington, Alleghany County._—In 1901 there was sent to the U. S. National Museum by Dr. A. C. Jones, of Covington, a lower last molar of a mastodon found at that place. This tooth differs from the ordinary teeth of _Mammut americanum_ in having the crown more depressed. The writer has observed similar teeth which have been found elsewhere. It is possible that they belonged to a species distinct from _M. americanum_. Dr. Jones informed the writer that the tooth was found within the city limits of Covington, about 300 yards from Jackson River, at a depth of 12 feet, in brick clay.
6. _Hot Springs, Bath County._—In the U. S. National Museum is a part of an upper left second true molar, recorded as having been found about a mile from the Hot Springs Hotel. The tooth is silicified. It was presented by Mr. J. F. McAllister. Hot Springs is at the head of Wilson Creek, a tributary of Jackson River. In the folio of Monterey Quadrangle coming down nearly to Hot Springs, no mention is made of any Pleistocene; but the presence of occasional deposits of soils along some of the streams is recorded. Evidently some of these deposits were laid down in Pleistocene times.
7. _Edom, Rockingham County._—The American Geologist in 1891 (vol. VII, p. 335), contains an account of the finding at this place of bones of what was called a mammoth, but which was more probably a mastodon. It was said to have been discovered on the land of a Mr. Frank. The information was furnished by Dr. Zirkle, who stated that a nearly complete skull had been found.
In the U. S. National Museum is the symphysis of the lower jaw of a mastodon, recorded only as having been found in Virginia. The specimen (No. 210) would not be worth mentioning were it not that it presents in front two sockets for tusks of considerable size. The bases of the tusks are retained at the bottom of the sockets. The left socket has a diameter of about 35 mm.; the other is slightly smaller. From the outside of one socket to the outside of the other is 94 mm. The front of the symphysis is damaged, so that its length can not be determined. Its lower face is quite flat. The height of the jaw at the front of the tooth which was present is about 150 mm. It seems to the writer that this jaw belonged to the species _Mammut progenium_.
