PRESENT DISTRIBUTION OF DISEASE 



During the early season of 1909 

 large shipments of foreign seedling 

 pines were received in the Continent 

 of America, part of which went to 

 New York, New Jersey, New Hamp- 

 shire, Pennsylvania, Connecticut, 

 Vermont, Massachussets, Ohio and 

 Indiana. But a portion of the same 

 shipments was introduced into Can- 

 ada. In all of these States, and also 

 as far as Minnesota, the disease is 

 now established, as well as in parts 

 of Canada. It was first discovered 

 in the year 1914, near Guelph, 

 Ontario, and later in other parts of 

 the Niagara Peninsula, mainly on 

 currants, but, unfortunately, on 

 native pines' also. It is now dis- 

 tributed generally in Southern 



Ontario, but may not yet have 

 reached the important white pine 

 section, although no systematic 

 search has been possible there. Quite 

 recently the currant rust stage was 

 found in Ottawa; as it was also this 

 season in certain localities of Quebec 

 province. Very urgent need exists 

 for systematical inspection of all pine 

 areas. In the west no inspection has 

 yet been possible. 



It is gratifying to note also that 

 both the Ontario and Quebec govern- 

 ments have become deeply interested, 

 and much work promises to be done 

 next year. It would be a matter for 

 congratulation if the government in- 

 spectors should be aided by the 

 employees of lumber companies and 

 other concerns interested. 



VALUE OF WHITE PINE LUMBER CUT IN 1915 



In Bulletin 58A, published by the 

 Forestry Branch, Department of the 

 Interior, the white pine lumber, in- 

 cluding both species. White Pine 

 {Pinus Strobus) and Western white 

 pine (Pinus monticola), is valued at 

 $17,584,149 for 1915, or nearly three 

 quarters of the value of the five 

 commercial spruce species of Canada 

 taken together. 



It is to be hoped that the matter 

 dealt with in this article will be fully 

 discussed at a meeting in the near 

 future, at which all interested parties 

 may be represented. Co-operative 

 effort alone will save the situation. 

 Meanwhile, if, as a result of this 

 article, attention and careful thought 

 become focussed on its subject matter, 

 something will have been accom- 

 plished. 



In conclusion, I wish to anticipate 

 the probable charge against me of 



crying out "wolf" causelessly, and of 

 taking too alarming a view of the 

 situation. Let me most emphatically 

 re-iterate, I am an alarmist, and am 

 so of set conviction in this matter. 

 My attitude is based on the ex- 

 perience of other countries, with 

 forest timber diseases, on the already 

 rapid and insidious spread of this 

 particular disease in America, and 

 lastly, but not least, on the import- 

 ance of rousing to action all con- 

 cerned, while there is yet time. So 

 surely as my warnings lie unheeded, 

 will the ultimate loss of trade and 

 revenue fall on all, whether or not 

 interested financially now, in the 

 White Pine Industry, one of the prime 

 factors in our Dominion's vast re- 



sources.
