54 %HE ADIRONDACK BLACK SP&UCE. 



In connection with the preceding tables it may be stated that 

 all of the 700 trees first examined were found on Township 20, 

 Franklin county, between two large ponds, Floodwood and Long 

 Pond. The two main slopes on this land run north and south, 

 with little or no difference in the timber on either slope. This 

 township has an average elevation of about 1,600 feet above the 

 sea. The spruce was above the average in quantity per acre, and 

 in quality it was first class. The trees were thrifty, but few 

 being found that were rotten at the stump. Not a tree had died 

 within the past ten years, the absence of any dead spruce having 

 been noted by the foresters. In size the trees were above the 

 average diameter for Adirondack black spruce. 



On Township 20, in a few places where the spruce was stand- 

 ing in " clumps," there was a yield of 40 standard logs (8,000 

 feet, B. M.) per acre ; where it was scattered through the other 

 timber, 15 standards (3,000 feet) would be a fair average. 



On Lots 34 and 35, Township 3, St. Lawrence county, the spruce 

 growing in clumps measured, in two different places, 35 standard 

 logs (7,000 feet) to the acre. Where it was scattered among other 

 species, it measured 12 standards per acre on an average. 



On Lots 50 and 63, Township 3, St. Lawrence county, the 

 spruce did not grow in clumps at all, but averaged 15 standard 

 logs to the acre. 



The spruce in each case was growing either in small clumps or 

 was scattered among hardwoods composed of beech, hard maple, 

 and yellow birch, the beech predominating in number of trees, 

 although of inferior diameter and height. The black spruce over- 

 tops the hardwoods where its diameter exceeds 14 inches ; 

 when standing in clumps it is taller than the scattered spruces oi 

 the same diameter growing among the hardwoods. Where it 

 grows in clumps the spruce has a small crown, the limbs being 

 small and short ; but in a scattering growth the spruces, as soon 

 as they overtop surrounding hardwoods, put out their limbs 

 thickly and large. 



A spruce 20 inches in diameter growing in a clump of spruces 

 will yield five logs, 13 feet 4 inches in length, while one of the same 

 diameter in a scattered growth mixed with hardwoods will yield but 

 four logs. In the one growing among hardwoods, after four logs
