and $8.94 in 1917 — an increa.se of $2.23 per cord, or nearly 33.2 per 

 cent, in the two years. 



Theorder of importance of the five provinces remained the same as 

 in 1916, Quebec leading with 1,109,869 cords, or over half the total; 

 Ontario second, with 735,691 cords, or over a third of the total ; British 

 Columbia third, with 134,814 cords; New Brunswick fourth, with 

 105,586 cords, and Nova Scotia last, with 18,374 cords. The quantity 

 of pulpwood consumed in each province is an increase in every case, 

 as is the average value per cord of wood. 



Spruce continues to lead all classes of wood, being 79.7 per cent of 

 the total in 191 7, balsam fir and hemlock being next in order of impor- 

 tance. These three woods all show increases from 1916. Poplar and 

 pine show decreases from the preceding year and tamarack and cedar 

 are reported from British Columbia for the first time in several years. 



Heart Rot in Western Yellow Pine 



Upon logged-off lands of the Flathead Indian Reservation the decay 

 in western yellow pine occurs largely in strips and patches. These 

 areas were very noticeable on account of the large number of culled 

 logs remaining after logging operations were completed. An investiga- 

 tion of the trees on eight different parts of the cut-over land was made. 

 My results, taken from 223 trees, are listed below: 



Shallow = to I foot depth, with some outcrop of rock. 



There was very little external evidence of decay in the standing 

 trees. \^ery frequently those in the worst stages had thrifty crowns 

 and a]j]jarently jjerfect boles. Neither was decay restricted to large 

 mature timber. Trees as small as 16 inches d. b. h. were frequently as 

 badly affected as were trees of 40 inclies d. b. Ii. The heaviest defect
