being urged whereby a number, and it is believed a relatively large number, 

 of the largest and most up-to-date spraying machines on the market will be 

 distributed among the more progressive of the Farmers' Institutes, to be 

 owned and used co-operatively by the members. The difference which 

 this movement, if successful, will make in the potato industry of the Garden 

 Province is perhaps not easily realized at present, but its results will be 

 far-reaching. 



The reader in Nova Scotia and Prince Edward Island is referred to the 

 occasional bulletins and annual reports of the Dominion Experimental 

 Farms, Ottawa (which are sent regularly, free on request) for more extended 

 information ; or further details will be gladly supplied from the laboratory. 

 The officer in charge is at all times anxious to meet farmers and to discuss 

 with them the diseases of farm crops and their remedies. If necessary and 

 practicable a visit will be made and the necessary advice and treatment 

 given. Considering the short time the laboratory has been established, a 

 surprisingly large amount of correspondence has been addressed to it. 

 It is only by a further extension along this line that the greatest use can be 

 made of the establishment and the undoubtedly large losses now caused by 

 plant disease curtailed. Letters (which must be stamped) addressed to the 

 Laboratory of Plant Pathology, Charlottetown, P.E.I., will have prompt 

 attention. 



FIELD LABORATORY OF PLANT PATHOLOGY FOR NEW BRUNSWICK AND 



QUEBEC 



G. C. Cunningham, B.S.A., Assistant in charge 



The establishment of the branch laboratory at Fredericton, N.B., was 

 the outgrowth of the potato inspection system inaugurated by the Dominion 

 Department of Agriculture in 1912. This inspection, aiming at preventing 

 the spread of various diseases, particularly powdery scab, proved of inestim- 

 able value in calling the attention of the Department authorities and the 

 farmers in general to various diseases which were causing serious losses 

 throughout the Dominion. The importance of this step is only now being 

 recognized. For instance, powdery scab which was promising to become 

 prevalent in many potato growing sections, has scarcely occurred, or only 

 very rarely, during the last two years. A survey showed that farmers who 

 had large quantities of potatoes infected with powdery scab in 1914, have 

 almosteliminated this trouble from their crop. In the spring of 1916 it was
