PKELIMINARY ACCOUNT OF THE FORESTS IN 

 CUMBERLAND COUNTY, ILLINOIS. 



By Arthur G. Vestal_, Stanford University^ Cal. 



Cumberland County is at the northern edge of the lower 

 Illinoisan till-plain. The upland soil is a silt loam, very 

 poorly drained, because of the level surface and the im- 

 pervious clay subsoil. Practically the whole area is 

 drained by the Embarrass river, which runs south through 

 the eastern part of the county. The valley of the Embar- 

 rass is 80 to 100 feet deep and in most places about one and 

 a half miles wide.
