We are aiiiiroaching very rapidly a condition in the Province of British 

 Columbia, in regard to insects of importance to the agriculturist and fruit-grower, 

 which will very soon demand most serious consideration. We are reaching a 

 point in which the whole system of orchard-management in relation to spraying 

 will have to be reconstructed and viewed from a different light than heretofore. 

 The importance of such pests as the codling-moth. San Jose scale. pear-thri]is. woolly 

 aphis, and black currant bud-mite cannot be loo lightly de,-ilt with. The fruit- 

 growers of I'.ritish Coliimliia. as will bei-ome evident in the pa.ires that folbiw. have 

 since the inception of the fruit-growing industry relied on two main considerations; 

 el) The youth of their industry and the production of fruit free of serious jiests 

 which beset fruit-growers in other sections of Canada: and (2) the wise considera- 

 tions of the Provincial Government aud the r'roviucial Board of Horticulture, who 

 liave dealt witli insect pests in most drastic manners, both through an efficient system 

 of (piarantine and inspection at the ports of entry, and through careful and |iains-
