154 KEPORT OF OFFICE OF EXPERIMENT STATIONS. 



roAv test of corn conducted since 1907 was continued and has resulted 

 in a marked variation in yield among the Jitferent varieties. Fer- 

 tilizer tests on grass lands to determine the effects of various ferti- 

 lizer elements on the yield of hay on the bowlder clay type of soil 

 were carried on as previously outlined. The results of five years' 

 work indicated the value of nitrate of soda for top-dressing on this 

 kind of soil. Pasture-improvement work was conducted on six plats, 

 and experiments on soil inoculation for leguminous plants were in 

 progress. 



The department of botany carried on spraying experiments with 

 Bordeaux mixture and various lime-sulphur washes. A number of 

 insecticides were applied with the lime sulphur to determine their 

 comparative efficiency and their tendency to injure the plants. 



The entomological department made considerable progress in add- 

 ing to its economic collections, studying the blister mite, apple leaf- 

 hopper, and other apple insects, as outbreaks of these pests occurred, 

 and in making observations with reference to the repression of black 

 flies, deer flies, and midges. 



In animal husbandry a sheep-feeding experiment was completed 

 and the results published as Bulletin 152 of the station. The prin- 

 cipal feature of this work was the comparison of clover hay and of 

 hay consisting of timothy and native grasses for sheep and lamb 

 feeding, together with a study of the value of turnips in the ration. 

 Work relating to the eradication of the stomach worm in sheep was 

 continued during the year. 



The chemist, among other lines of work, continued studies on the 

 liming of soils. The results secured in the preliminary tests gave 

 no evidence that lime was needed on the soils under experiment. 



In horticulture observations were made on varieties of plums with 

 reference to pruning, blossoming, time of bearing, yielding capacity, 

 etc., and a variety test of apples was carried on in an orchard with 

 part of the trees 5 years and part 9 years old. Work with carnations 

 and lettuce was closed out during the year and fertilizer experiments 

 with potatoes were begun. An orchard sur\'ey of the State was 

 carried forward as an extension feature. 



The station is carrying on cooperative experiments with fanners 

 in hay culture and with this department in conducting farm sur- 

 veys. The members of the station staff have assisted to some extent 

 in fanners' institute and extension work. 



The following publications were received from this station during 

 the year: Bulletins 148, Results of Seed Tests for 1910; 149, Results 

 of the Feed Inspection for 1910; 150, Results of Fertilizer Inspec- 

 tion for 1910; 151, Twenty-first and Twenty-second Reports; 152,
