276 LIFE OF THE PLEISTOCENE 



Deposits apparently referable to the Yarmouth horizon, altho a few of these 

 may prove to be of Sangamon age, have been recorded as follows: 



Vigo, 122 Bartholomew, 123 Warren, 124 Brown, 120 Jennings, 126 Vermilion, 127 

 Clay, 127 Knox, 128 Dubois, 129 Parke, 129 Ohio, 129 and Franklin 130 counties. 



10. OHIO 



References to the old soil and old forest beds of Ohio are very numerous. 

 Many of these are indefinite and may refer to either the Yarmouth or the 

 Sangamon intervals. In Montgomery County, near Germantown, a section 

 passed thru two tills and penetrated a peat bed of considerable thickness. 

 This is shown below: 



Section on Twin Creek 



1. Till (Wisconsin) 60-70 feet 



2. Stratified sand and gravel (Sangamon) 10 " 



3. Till (Illinoian) 15-25 " 



4. Peat in saucer shaped depression (Yarmouth) 12-20 " 



The upper layers of peat (No. 4) contained the species of plants indicated 

 below: 131 



Sphagnum moss Juniperus virginiamts 



Grasses Coniferous wood 



Sedges 



Three species of mammals are reported. 



Elephas 



Mastodon americanus 



Castoroides ohioensis • 



It is said that scarcely a square mile in Montgomery County is without this 

 peat stratum. 



It is believed that records of the old forest bed in southern Ohio should be 

 referred to the Yarmouth interval, as they underlie deposits apparently refer-
