because of the uniformity of the growth the area was practically 

 cleaned, leaving only scattered clumps of spruce two or three in a clump 

 or sometimes single trees. 



The result of the operation is that no excessive windfall was noted 

 and reproduction of spruce and fir covers the ground. The greater 

 number is of one age class, namely, an average of 15 years, with about 

 2 to 3 inches in diameter and 16 feet high. The height growth in the 

 last three years in fir averaged 14 inches, while in spruce the growth 

 is somewhat less. Besides this more or less even-aged class, there is 

 reproduction from 12 feet high down to one-year-old seedlings. About 

 75 per cent of the new growth is fir. Reproduction is ample ; in fact, 

 in a few years the trees will feel the effects of being crowded. 



Here, in this particular site, the soil was fairly deep and the few 

 remaining large trees were not wind-thrown. 



This plot is an example of good silviculture, excepting that too many 

 trees were left for seed. 



Spruce Plat, 1 2-iiicli Diameter Limit. Cut IQOO 



West of McKeen's Falls, on the Dead Diamond River, is a repre- 

 sentation of this type. Cut to a diameter limit of 12 inches about 10 

 or 1 1 years ago, there are now standing a good many trees from 6 to 

 10 inches in diameter, while the ground is covered with reproduction 

 6 to 10 feet high. Windfall is taking some of the old trees, but as a 

 whole the site is protected. The present stand might cut two or three 

 cords to the acre. It would be murdering the reproduction to go in and 

 cut the older trees unless extreme care was taken. The cost of logging 

 the remaining stand would be increased by the small cut per acre obtain- 

 able. Fewer seed trees would have served as well for reproduction 

 if any were needed. 



A saving in the cost of logging, by taking more trees and ignoring 

 the rigid diameter limit, might have been made, for more lumber per 

 acre could have been cut. If the stand is entered now. much reproduc- 

 tion will be destroyed, and if the stand is not entered, the old trees will 

 be wind-thrown or die before the second crop is ready for cutting. 



The reproduction is mostly fir 6 to 15 feet high, coming in under a 

 scattering of spruce 6 to 10 inches in diameter. The crowns of the 

 spruce are small and the growth is slow. The trees are over 100 years 

 old and no increased growth was found by testing with the increment 

 borer.
