30. _Ashley, Steuben County._—The American Museum of Natural History, New York, contains the fine skull of a mastodon, found in Steuben Township not far from Ashley. The finder of the skull, Mr. Walter F. Deller, of Ashley, informed the writer that it was discovered in a swamp which was being drained, about 5 feet from the surface. He states that the bones lay in a marl, itself overlain by muck, and on top of all some soil which had been washed in. So far as can be determined, the animal was buried between the Mississinawa and the Salamonie moraines. With the skull were found other parts of the skeleton, which shows that the remains were in their original place of burial. MASTODONS FOUND OUTSIDE OF MISSISSINAWA MORAINE AND BETWEEN WABASH AND KANKAKEE RIVERS. 31. _Beaver Lake, Newton County._—In 1870 (Geol. Surv. Illinois, vol. IV, p. 229), Frank H. Bradley reported that in draining Beaver Lake, in Newton County, mastodon remains had been found, in company with _Boötherium_. No details were furnished, and it is not known what was done with the specimens. It is probable that the musk-ox belonged to the species _Symbos cavifrons_. It occurs over the country much more abundantly than any other musk-ox. Beaver Lake has disappeared from the maps, but it is shown on the geological map of Indiana, published in the Eighteenth Annual Report of the Geological Survey of Indiana. The lake occupied a part of the present township of McClellan (township 30 north, range 9 west). Doubtless this lake existed ever since the retirement of the ice from that region. The mastodon was probably found in making the ditch from the lake in a northwesterly direction into the Kankakee River. 32. _Jasper County._—John Collett, at that time State geologist, reported in 1882 (12th Ann. Rep. Geol. Surv. Indiana, p. 73) that remains of a mastodon had been found in this county, but no particulars were furnished. He stated that remains of this species, as well as those of the mammoth, were buried in deposits of peat. A portion of the county is occupied by the Marseilles morainic system, the remainder by the Kankakee marsh, perhaps largely a lake during the latter part of the Wisconsin stage. On the maps the number 32 is placed arbitrarily.
