Tract H. (Vermilion Township. See. 6, Above Vermilion 

 Kiver). 



This was rather a thin stand of white oak, bur oak, black 

 oak and shagbark hickory, on upland soil, just past 

 Bailey's Falls. Some cutting had been done recently, and 

 hazel brush, blackberry bushes and asters formed the main 

 undergrowth. The stand, as was found from ring counts 

 on stumps was from 75 to 80 years old. The trees were 

 short, not averaging more than ll^ sixteen-foot logs per 

 tree, reproduction consisting mostly of white oak and black 

 walnut.

Tract I. (Sec. 7, Above Vermilion Kiver). 



This was one of the best stands examined, so far as forest 

 conditions were concerned, but did not average quite so 

 high as tract F. The tract comprises about 160 acres, and 

 the leading species in order are white, black, and red oak. 

 The soil is a brown silt loam and the ravines were deep 

 enough to give some little difference of forest composition 

 due to soil moisture, so strips were run across the ravines. 



Grazing had been light and there were about 26 three- 

 inch trees per acre. Seedlings consisted of elm, ash, and 

 white oak, the latter being where openings had been made 

 in the stand by cutting. Clear length was good, and trees 

 would make about two 16-foot logs per tree. The humus 

 was about three inches deep, well decayed with a layer of 

 hardwood leaves on top. The composition of stand was as 

 follows :
