The export of pulpwood declined somewhat below the previous 

 year, but was still 40.3 per cent of the total production; altogether 

 the total rise in exports of pulpwood for the last 8 years was not 

 great, but while the wood pulp export also decreased under the 

 previous year in amount, in value it increased due to considerably 

 higher price ($25.48 as against $20.87). The United States take, 

 of course, the largest proportion of these exports, the proportion 

 in export of wood pulp having grown to over 87 per cent. 



The bulletin on poles and cross-ties is based on data from 381 

 purchasing firms. The total of poles for all uses in 1914 had 

 fallen considerably, nearly to one half the purchases for 1913, 

 showing differently from the pulp situation the influence of the 

 war. Continuous reduction in pole purchases are, however, notice- 

 able since 1910, when over 780,000 poles figures, as against 283,184 

 in 1914, the price being slightly advanced over the previous year 

 to $2.33, or $660,262 altogether. Cedar forms 85 per cent of the 

 output. 



The purchase of cross-ties was practically the same in the 

 last three years, and considerably larger than in 1910 and 1911, 

 not quite 20 million at an average value of 45 cents. Jack pine and 

 cedar furnishing the bulk (over one half) ; tamarack, Douglas fir, 

 hemlock, Western larch and spruce in almost equal quantities, 

 one third of the consumption.

Dr. Weir names and describes this new, and apparently wide- 

 spread, disease and its results. It is distributed throughout the 

 northwestern United States and Western Canada; its distribution 

 southward is still unknown. It is readily recognized by the foliage, 

 first yellowing, then browning in patches, beginning at the tips, 

 or by the formation of witches' brooms. It attacks all age classes 

 and kills seedlings. In mature trees it probably influences incre- 

 ment, but does not otherwise prove detrimental and affected trees
