23. _Losantville, Randolph County._—Losantville is, according to Leverett (Monogr. U. S. Geol. Surv. LIII, plate VI), on the Bloomington moraine of the Wisconsin. As indicated on the map, the drift is covered with silt formed in local ice-border pools. Hence the mastodon in question left his bones in a depression on the top of the Wisconsin drift-sheet, and later they were covered by a deposit of peat. In Nautilus, volume IV, page 131, Elwood Pleas, of Dunreith, Indiana, gave a list of six species of mollusks found associated with the mastodon. All are yet living. Dr. A. J. Phinney (Twelfth Ann. Rep. Ind. Geol. Surv., p. 181) stated that mastodon bones had been met in this county, but no details were furnished. 24. _Dalton, Wayne County._—In the Earlham College collection there is a lower jaw found in Nettle Creek, near Dalton. It contains the last two molars. The last one has five crests and a talon. The front of the symphysis is rough, but there are no alveoles for tusks. Dalton is in the northwestern corner of the county and on the southern border of the Shelbyville moraine, where this joins the Bloomington moraine. 25. _Jacksonburg, Wayne County._—Dr. John T. Plummer (Amer. Jour. Sci., ser. I, vol. XLIV, 1843, p. 302) stated that he had obtained near Jacksonburg, 18 miles west of Richmond, a tooth. It had four cross-ridges and was so well preserved that a dentist attempted to make artificial human teeth from it. According to Leverett’s map, the tooth was probably on the surface of Wisconsin drift. It could not, therefore, have lived until after the Shelbyville moraine had been cleared of ice. 26. _Richmond, Wayne County._—In the twelfth volume of the American Geologist, page 73, Professor Joseph Moore, then of Earlham College, stated that some sound teeth and decayed bones of a mastodon had been found 2 miles east of Richmond, in scooping out a fish-pond. A label on a lower last molar states that the remains were found on the Floyd farm. With them were found a fragment of an incisor of _Castoroides_. According to Leverett (Monogr. LIII, plate VI), the locality would be outside of the Bloomington moraine of the Wisconsin drift. MASTODONS FOUND WITHIN THE MISSISSINAWA MORAINE. 27. _Penn Township, Jay County._—Mr. David McCaslin (12th Ann. Rep. Geol. Surv. Indiana, p. 169) stated that various remains of mastodon had been found in Jay County. He mentioned in particular fragments found in Penn Township (township 24 north, range 8 east) and which seemed to indicate the presence of an entire skeleton. It is, however, possible that this skeleton was that of an elephant. The Salamonie moraine passes diagonally through this township.
