In the eight years since 1908 the pulpwood cut in Canada rose from 

 482,777 to 1,764,912 cords — almost fourfold and almost double since 

 19 1 2. The growth was steady and war conditions have practically 

 neither retarded nor increased it beyond the regular increases. This 

 cannot be said as regards value. The cord which in 1908 was valued 

 at $6 had increased in 1916 only to $7.42, or only 22 per cent; but the 

 increase in the last two years is 10 per cent above the previous one. 



The Province of Quebec produces about one-half of the total output 

 and Ontario a good third. As regards species, spruce furnished 68.2 

 per cent and fir 24.5 per cent ; but it is questionable whether the spruce 

 output does not contain some fir. As regards processes, sulphite fiber 

 has increased more than any of the other processes, equaling in the last 

 year the mechanical pulp in quantity, which latter, however, increased 

 also by 1 1 per cent. 



Canadian manufacture has increased generally, so that the percent- 

 age of export of unmanufactured material has decreased from 40.3 

 per cent of the total pulpwood cut to 37.7 per cent. This decrease dates 

 since 1912, when export still exceeded home manufacture. But the 

 export of wood-pulp tons since 1908 has shown more than 100 per cent 

 increase, although there were three years of decreases in the steady 

 advancement. In values this increase is even more striking, the values 

 of the last year being more than fourfold those of the first, with 

 $17,344,342, against which a negligible import of $552,000. 



A list of active mills, with location maps, is appended.

A Bud and Twig Key. By O. L. Sponsler. Ann Arbor, Mich. 1916. 

 Pp. 26. Price, 35 cents. George Wahr. 



This is a revised edition of a key, published in 191 1 in the Nebraska 

 Forest Club Annual, of about 85 species of the more important broad- 

 leaf trees of the United States, including a few exotics. For some 

 genera only a genus key is given, partly to save space, partly because 

 no distinctions could be made, as in the case of the ashes and the red 

 and silver maples ; the two black walnuts and two of the hickories seem 

 also to present difficulties in distinguishing by bud and twig.
