CoMFAKATivE Yield of Spruce axd Vise Grown up Thickly on Open L.and. 



Xow, on page 185 of this report it was said if our spruce ever gave out 

 and we wanted to grow timber to supply our pulp mills, that if the pulp 

 mill men would content themselves with pine lumber we could cover a 

 hirge section of the State over with thick pine groves producing great 

 amounts and values. These figures will help justify a pait of that state- 

 ment. They will show at any rate why it is to pine and not to spruce 

 that we should pi-obably look in any such emergency. Such compara- 

 tive figures of course would not hold in all conditions true. So far as I 

 can judge, however, the.se figures are somewhere near representative of 

 their rei<i)ective species. 



D — Grov/th on Spruce in Cut-Over Lands in Per Cent and 



Amount* 



On jjages 26 to -28 of this report Pressler's tables for determining the 

 percentage of growth of trees wei-e explained, and illustration given of 

 their use. Later, on pages 5G and 12."5, were given some of the general 

 results arrived at by this means. It remains now to record the results 

 iti full and to state or restate the most impoitant inferences derived there- 

 from. 



The observations made were all on spruce trees, on those of small and 

 medium size. When notes of this kind were taken note was also made of 

 the soil, nature of growtii, etc., ami the tree observations have been 

 divided in accordance therewith. Thus the figures obtained on the Ken- 

 nebec wei-e divitled into ;i groups, for s|)ruc(! in hard wood or mixed laud, 

 and in thrifty and unlhrit'ty black grovvth respectively.
