From these figures the capacity of the White Pine to produce large amounts of valuable stem- 

 wood is apparent. Thus, on soil on which the KM) year-old trees developed only a height of 92 

 feet, over 13,000 cubic feet of stemwood, corresponding to about tj(),()00 to 70,000 feet B. M., 

 American scale, were cut per acre over and above about 1,200 cubic feet of material removed in 

 previous thinnings. In every case the "Wliite Pine excels the common pine, and even the Spruce 

 in this respect. It should be added that most of these plantations, made in the early part of this 

 century, were not executed according to present superior methods, the species being an exotic and 

 expensive was set out more in orchard fashion, as most planters in our country have been apt 

 to do, at distances of 8, 12, and more feet apart. Owing to this fact the development was prob- 

 ably not as satisfactory in the earlier years as it might have been had the method of close planting, 

 either pure or in mixture, prevailed. 



The superiority of growth over the German Spruce and Pine is more fully illustrated in tiie 

 following table, which shows the distribution and proportion of trees of White Pine and Spruce 

 and of White Pine and Scotch Pine that are found in given diameter classes in two mixed planted 

 growths of these species : 



Distrihnlion and proporliou of While I'ine and .^jtrnct- and IVhiti T'ine and Scolcli Pine. 



It appears that nearly 32 per cent of the White Pine is over 12 inches In diameter, as against 

 less than 7 per cent of the Spruce, while 35 jier cent of White Pine, as against 0.5 per cent of 

 Scotch Pine, developed over 12 inches in the mixture of these two, aiid over II per cent of the 

 former belongs to sizes above 14 inches, which is hardly reachetl at that age by its competitor. 

 These tigures prove clearly that the White Pine excels the Scotch Pine even during the age of
