THE CANADIAN FORESTER'S 



Though this table is pretty correct, we must not forget 

 that wood raries very much in density, according to the 

 land it grows on. The table having been drawn up for 

 the middle region of the States, the figures may, doubt- 

 less, differ a little from those which the same species 

 grown in Canada would indicate. 



The next table, showing the weight ot the chief sorts 

 of fire-wood found on our markets, will give a better 

 idea of their relative values. Indeed, considered in 

 regard to weight, one piece of wood is as good as another 

 as fuel, though the two may differ much in point of size. 

 Thus, a pound of poplar is worth quite as much as a 

 pound of hard-maple. But a piece of poplar weighing a 

 pound is much larger than a piece of hard-maple of the 

 same weight, and, consequently, it will take up much 

 more room in a cord, which will, of course, weigh less 

 than a cord of hard-maple, arid be of less value, as may 

 be seen in the next table : — 



So much for the value of trees as fire-wood. Let us 

 now see how trees rank when considered as materials 

 for building, etc.: — 



Oak. 



Walnuts. 



Hickories. 



Sugar-maple. 



Pine. 



White-ash. 



Black-birch. 



Elm. 



Larch. 



Yellow-birch. 



Spiuce. 



Arbor vitae.
