The status of a sample from a T5-year old stand of mixed hardwood 

 in Hancock county is here shown. 



Along the Illinois River from the Hennepin bend down to Peoria, 

 the narrow draws, running back into the western bluffs some two or three 

 miles, as well as the face of the bluff, are wooded as a continuous belt 

 with this mixed hardwood subtype. Elsewhere cleared bluffs and draws 

 are as frequent as wooded ones. In the northeastern part of Calhoun 

 and extending into the southeastern corner of Pike county is an area of 

 upland where the soils are heavy. Here this mixed hardwood phase 

 changes to scrub and post oak. In many places near the Illinois valley, 

 notably in Mason county, sands have buried the old soils ; and in such 

 places the stands are of the type described under "scrub oak". 



Throughout the interior of the state this mixed hardwood subtype 

 occurs on the moraines and well-drained uplands, more frequently near 

 the Indiana line in Vermilion county and the Wisconsin line in Winne- 

 bago and Stephenson counties ; but it is usually less frequent than the oak- 

 hickory extreme, even in these regions. 



A sample plot from a virgin stand in McLean county shows the 

 splendid sizes attained by trees under conditions favorable to this type.
