SILVICAL SYSTEMS IN NEW HAMPSHIRE; 903 



trees have had plenty of Hght for the last 15 years, they have made no 

 appreciable increased growth. On a few the leaders are beginning to 

 lengthen out, and this year's growth is probably 6 inches. However, 

 the majority are hanging on to life. Some of these trees are 75 to 100 

 years old. 



Keeping in mind the fact that the area cut is 2 by 3 miles and that 

 the trees were all taken excepting very small suppressed trees that were 

 not capable of reseeding the area, yet we have the ground covered with 

 reproduction of spruce and fir. 



The new growth is 40 per cent spruce and 60 per cent tir. The trees 

 are about 14 to 15 years old; the fir 12 to 14 feet high and the spruce 

 8 to 10 feet high. Some of the fir trees measured 4 inches in diameter 

 at the collar, 17 feet high, 17 years old, and showed eight rings to the 

 inch at d. b. h. Spruce is 4 inches in diameter at the collar, 13 feet 

 high, and 17 years old. The main portion of the new reproduction, 

 however, averages somewhat less in height, but the age class is a fairh- 

 uniform one of 14 to 17 years. This reproduction is on the ground only 

 where roads were not made. In peeling and hauling short wood, numer- 

 ous roads are made. However, here could be traced the old main roads 

 and* many of the lesser roads. Spruce and fir growth was dense at the 

 sides of the roads, but there was none in the roads. 



It appears, then, that unless seed trees were on the area, since the 

 area is fairly evenly stocked and is too large to be seeded in from the 

 sides and no growth is in the roads, the reproduction must have been 

 present at the time of cutting. 



RKPRODUCTIOX OF SOFTWOODS IN Tlli; II.AKUWOOD 'J'VPF 



At least 50 per cent of northern New Hampshire is in the hardwood 

 type — that is, softwood is mixed with hardwood, but the hardwood is 

 present in greater porportion than the softwood. 



Usually just the softwood is cut and the resulting reprcnluction is as 

 described in the foregoing })ages. Some areas where the hardwoods 

 were cut, too, were visited in order to study the resulting reproduction.

One concern has for the last six years been operating in Dummer. 

 cutting hardwoods and any .softwoods that may have been left. Mo.st 

 of the sj)rucc was cut for logs a niunlxr of years ago, but there was 

 left a scattering of small spruce and fir, 6 to 10 inches in diameter, as 

 was evidenced by the numerous softwood skids in tlu' log-haulinu 

 roads.
