FOSSIL MASTODON AND MAMMOTH REMAINS. 15 



OGLE COUNTY. 



Byron. — Some years ago a large bone, supposed to be from 

 the foreleg of a mastodon, was found two or three miles above 

 Byron. The bank of Hock river had caved down for some dis- 

 tance back from the stream; some five feet below the surface of 

 the highland coming up to the river and about fifteen feet above 

 ordinary water level, the bone was found sticking in the bank. 

 The bank seems to be a sort of modified drift made up of some- 

 what marly, dark-colored, alluvial clay intermixed with river 

 sand and considerable gravel. The formation is hardly alluvium, 

 but seems to be a kind of river drift. The fossil is light, porous, 

 and whitish in color, in rather poor state of preservation. We ob- 

 tained it through the courtesy of Mr. Mix and sent it to the State 

 Geological Cabinet.

Harper. — A number of years ago Mr. Gross found the tdoth of 

 a mastodon on his farm in Forreston township, one mile south of 

 Harper. A small stream cuts through the farm, and one spring, 

 after a freshet, the tooth was found in a large bed of gravel which 

 had been washed to one place along the shore of the stream. The 

 freshet washed a hole about nine feet deep out of the bed of the 

 stream just above this gravel bed, and the finder, thinking that 

 the tooth might have been washed out of this place, made a dili- 

 gent search for other remains, but failed to find anything. The 

 tooth measures eight inches in length and four and a half inches 

 in width at the widest point, and is in an excellent state of preser- 

 vation, having smooth polished surfaces. Another tooth was 

 found in the same place a short time before by a Mr. Ainsworth.

 sils at F. G. Rossman's, a farmer living near Roch'elle, which he
