Director, Dominion Experimental Farms, 

 Ottawa. 



SIR, I have the honour to submit herewith the manuscript of a bulletin 

 on "A Preliminary Survey of Forest Insect Conditions in British Columbia," 

 which has been prepared by Mr. J. M. Swaine, M.Sc., by whom the investigation 

 was undertaken. It is recommended that this manuscript be published as a 

 Bulletin of the Second Series. 



Frequent reports of serious forest insect depredations in British Columbia 

 have been received during the last few years, and in view of the high commercial 

 value of the merchantable timber in the province, an investigation was pro- 

 jected. A request from the Minister of Lands of the province that such an 

 investigation should take place coincided with our own wishes, and enabled 

 us to arrange for the work to be carried on in co-operation with the provincial 

 forestry officers. The Provincial Government contributed to the expenses of 

 the investigation by defraying Mr. Swaine's expenses while in the province. 

 I wish to acknowledge the assistance which Mr. H. R. MacMillan, Chief Forester 

 of British Columbia, with whom the details of the work were arranged, rendered 

 on all occasions. 



The present bulletin has been written with a view to assisting immediately 

 the lumbermen and owners of timber limits in the matter of recognizing the 

 commoner species of injurious beetles, and their injuries, with a view to the 

 adoption of the control measures which are described. The cost of the carrying 

 out of these control measures is very frequently more than covered by the 

 sale of the logs in addition to checking the outbreak of beetles which might 

 result in the destruction of a large amount of timber. 



I have the honour to be, sir, 



Your obedient servant, 



C. GORDON HEWITT, 



Dominion Encomologist.
