Cooks Falls, Delaware County, N. Y.; altitude 1,300 feet; slope 20 per cent, east by south; soil very 

 shallow, fine, crumbly loam, fresh and rich, very full of flat sandstone fragments; humus 2 inches deep, 

 well decomposed ; plot one-ei ghth acre in similar stand of 8 or 10 acres, which contains scattered older trees. 

 The trees are mostly of sprout origin. Basswood and ash, especially, grew in clumps of numerous sprouts, 

 from small stump. Density 0.9; reproduction, a few unthrifty sugar-maple seedlings. 



Plot No. 15. — Age, 32 years; yield, 19.8 cords per acre; average height of dominant trees, 48 feet.

Cooks Falls, Delaware County, N. Y.; altitude 1,300 feet; slope lOper cent, south; soil very shallow, fresh, 

 sandy loam, very full of rock fragments; humus rather dry, 1| inches deep; plot one-eighth acre, representa- 

 tive of more than 10 acres of second growth, containing scattered larger trees; density 1, but south exposure 

 permits golden rod among the ground cover. The beech are mostly root sprouts 1 and 2 inches in diameter, 

 and most of these are badly suppressed, many dying, and some dead. The dead and dying were not 

 counted. Reproduction occasional aspen, red maple, and cherry seedlings; none of beech. This plot is 

 in the same stand as the thinned plot described last in this list. 



Plot No. 16. — Age, 42 years; yield, 30.6 cords per acre; average height of dominant trees, 70 feet.
