24. Petersburg, Monroe County.—Alexander Winchell (Amer. Jour. Sci., vol. XXXVIII, 1864, p. 224) reported mastodon remains from this place. The town is in township 7 south, range 6 east. According to Leverett and Taylor’s map, Petersburg is within the beach which marks the old glacial Lake Warren. Probably, therefore, this mastodon lived after the retirement of this lake, unless it had lived during the time of Lake Wayne and been covered over by the deposits of Lake Warren when the waters of the latter made their advance on the land. The time of the mastodon was more probably after both lakes had ceased to exist.
23. Saline, Washtenaw County.—Mr. N. A. Wood, of the University of Michigan, informed the writer that he had seen some mastodon remains which had been found here in 1880. No exact statements were given regarding the place. Saline is very close to the beach of old Lake Maumee, where this beach is crossed by Saline River and on the Defiance moraine.

26. Seven miles southeast of Ypsilanti, Washtenaw County.—In 1908 (Folio 155, U. S. Geol. Surv., p. 9), Russell and Leverett stated that remains of a mastodon had been found a few years previously on the farm of Albert Darling, about 7 miles southeast of Ypsilanti, where laborers were digging a ditch across a swampy field. The lower jaw with molar teeth in place, the left tusk, teeth of the upper jaw, portions of the cranium, some vertebræ and ribs, and some of the larger bones of the limbs were found. With considerable restoration these parts were mounted and placed in the museum of Michigan University. The locality must be not far away from Huron River and within the beach of old Arkona Lake, a predecessor of the present Lake Erie.

INDIANA.
Mastodons Found in the Unglaciated Region.
1. Posey County.—On page 341 of Blainville’s “Ostéographie des Mammifères,” volume III, it is stated that Lesueur had shown Blainville drawings of a fine vertebra and a femur, with its epiphyses, of a mastodon which had been found along the Wabash River. His language indicates that this was somewhere below New Harmony. He stated that these bones were in the library at Vincennes, Indiana. In answer to my inquiry about these bones, President Horace Ellis, of Vincennes University, informed me that some bones which appear to be those mentioned are in his university.
These remains were found in digging a well, at a depth of 60 feet. One of the curators of the library at Vincennes, Mr. Badollet, states that with these bones were some skin and hair. We may suppose that there was some mistake about this.
