in the serum. A chemical study was also made of the lime-snlphur 

 mixture used for sprays. The effect of different kinds of lime was 

 investigated, and it was found that lime containing magnesia does 

 not give as concentrated a solution for spraying as lime containing 

 no magnesia. 



The entomologist also worked with lime-sulphur sprays to deter- 

 mine whether they are as recommended, whether they can be used 

 in gas-spraying machines, and whether arsenicals can be applied 

 with them. The extent of dilution has received attention, and it is 

 urged that the sprays should be standardized as they are now on 

 the market in commercial form. Studies were further made of cab- 

 bage root maggots, maple Eriophyidw, apple and pear leaf hoppers, 

 clover mite, lesser tarnished plant bug, and the cherry ermine moth. 

 The brown-tail moth, the snowy tree cricket, the leaf blister mite, 

 and the leaf hoppers and their secondary hosts, were also studied. 



The bacteriological department, in addition to its Adams fund 

 work, also studied the milking machine with reference to the germ 

 content of the milk. It was found that cleaner milk can be obtained 

 with the machine than by hand milking, provided care is exercised. 



In agronomy some of the pot experiments with fertilizers were con- 

 tinued, and a variety of field experiments were carried on. 



The cooperative work of the station with farmers included experi- 

 ments in potato spraying and controlling currant cane blight, cabbage 

 black rot, and the cabbage maggot. The cooperative work with this 

 Department consisted in growing sugar beets and studying the control 

 of the Hessian fly. The station did no extension work, but took part 

 in farmers' institute work to some extent. 



The following publications were received from this station during 

 the year: Bulletins 299, popular edition, May weather and fruit 

 harvests; 302, popular edition. Is it wise to dip nursery stock? 303,
