44. _Green Township, Summit County._—Professor William C. Mills, of the State University of Ohio, has informed the writer that he had secured remains of a young mastodon in section 13 of this township (Tp. 2 N., R. 9 W.). The bones were found at a depth of about 30 inches and were badly decayed. The region is flat and lies in a bend of the headwaters of Tuscarawas River. 45. _Massillon, Stark County._—S. P. Hildreth, in 1837 (Amer. Jour. Sci., ser. 1, vol. XXXI, p. 56), reported that a year or two before he wrote some very large bones and tusks of a mastodon had been brought to light in excavating a mill-race near Massillon through a swamp or wet prairie. This city is situated on the Tuscarawas River. 46. _Canton, Stark County._—In the Cincinnati Inquirer of November 11, 1910, a paragraph announced that some boys, while digging in the east end of the city, had found 2 mastodon teeth. On November 26 the writer received a letter from Mr. N. D. Bush, of Canton, who described the teeth, so that it is certain that they were those of the mastodon. Both Massillon and Canton are situated on the broad Grand River moraine. 47. See page 70. 48. _Trumbull County._—Mr. John T. Plummer, in 1843 (Amer. Jour. Sci., ser. 1, vol. XLIV, p. 302, footnote), stated that he owned a grinder with 10 prominences which had been found in this county. Evidently the tooth was that of a mastodon, but the locality is somewhat vague. For 49 and 50 see page 74; for 51 see page 75. MICHIGAN. (Maps 5, 8.) 1. _Church, Hillsdale County._—In 1901 there was found, on the farm of Mr. Levi Wood, near Church, the greater part of the skeleton of a small mastodon. This was exhumed by an agent of the U. S. National Museum and is exhibited there. The animal is small and probably a female. The bones were found in a peat-swamp, not far from the surface. Those most deeply buried were only 4 feet from the surface, while others were down only about 2.5 feet. The whole of the township in which Church is situated is occupied by a part of the Mississinawa moraine, the outermost one formed by the Erie lobe of the Wisconsin ice. So far as the ground is concerned, the mastodon might have lived there long before the close of the Wisconsin stage at any time after the exposure of the moraine. This mastodon was described and figured by Mr. C. W. Gilmore in 1906 (Proc. U. S. Nat. Mus., vol. XXX, p. 610, plate XXXV).
