4. _Bellevue, Eaton County._—The writer has learned from Mr. N. A. Wood, of the University of Michigan, that mastodon remains had been described from near Bellevue by Mr. E. A. Foote, in the third volume of the Report of the Pioneer Society of Michigan, on pages 402–403. The animal was found on the farm of Mr. Charles Cummings. It was a large one, the femur having a length of 3 feet 10 inches and one tusk was over 12 feet in length. Four teeth belonged to the upper jaw. The remains must have been found before 1879. Bellevue is situated on the Kalamazoo River, which here traverses the Kalamazoo moraine. As in other cases in the central regions of the State, mastodons may have lived at a rather early stage after the Wisconsin ice began to withdraw; but they may have kept farther from the glacial front. 5. _Olivet, Eaton County._—Dr. A. C. Lane (Ann. Rept. Board of Geol. Surv. Michigan for 1901, p. 253) reported the finding of mastodon bones near Olivet. A letter from Professor Samuel Rittenhouse, of Olivet College, gives the information that many of the bones of the skeleton had been secured. These were exhumed from a marsh on the northwest quarter of section 11, township 1 north, range 5 west. Following Leverett and Taylor’s map, the locality seems to be on an esker through which flows Battle Creek. The country in this region is covered by the Kalamazoo morainic system of the Saginaw lobe. The mastodon must have been buried after the ice receded from that moraine. 6. _Stanton, Montcalm County._—Mr. N. A. Wood, preparator in the University of Michigan, informed the writer that Mr. L. C. Hodges, of Stanton, in 1911 found some mastodon teeth. Nothing more is known about these remains. Stanton is situated between the West Branch morainic system and the Charlotte system. 7. _Buchanan, Berrien County._—Mr. William Hillis Smith, of Niles, Michigan, informed the writer that many remains of mastodons were found in a large ditch made to drain the Bakerstown marsh. This ditch began south and west of Buchanan and emptied into Lake Michigan. It was 16 feet wide and 8 to 10 feet deep. In the course of the work bones and teeth were frequently thrown out by the steam shovel, especially bones of mastodons. One skull was badly crushed, but was repaired by Mr. E. H. Crane, of Kalamazoo, and sold to the Ward Establishment, of Rochester, New York. Exact statements as to localities are wanting, but the ditch was evidently located on and within the Valparaiso moraine. It is this moraine which runs around the southern end of Lake Michigan and separates the St. Lawrence drainage from that of the Mississippi; east of the lake it extends far north into Michigan. Naturally, this moraine was formed before the withdrawal of the Lake Michigan lobe of the Wisconsin glacier into that lake, and the mastodons might have lived, died, and been buried there at any time after the exposure of the moraine and the development of climatal conditions that permitted their existence.
