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.
33. _Denham, Pulaski County._—In 1915 the U. S. National Museum secured a large part of the skeleton of a mastodon found about 2 miles west of Denham. The locality is described to the writer by Mr. W. D. Pattison, of Winamac, as being on the half-section line between the southeast quarter of the northwest quarter and the northeast quarter of the southwest quarter of section 9, township 31 north, range 3 west. This would be not far west from the center of the section. The skeleton was thrown out by the shovel of the ditching machine, but most of the bones, including the skull, were obtained in quite good condition. They were found at a depth of about 9 feet, in a marly deposit, itself overlain by sandy materials.
