192 KEPORT OF OFFICE OF EXPERIMENT STATIONS. 



testing seed from different sour6es as well as individual plants was 

 started this year. In a pasture improvement experiment begim in 

 1909, various treatments such as harrowing, reseeding, fertilizing, 

 liming, plowing, and sheep pasturing were tried. 



The horticulturist continued variety tests of plums, apples, and 

 lettuce. The work with apples included the renovation of an orchard 

 formerly in sod by bringing the land into good tilth. Fertilizer tests 

 with lettuce were made in the greenhouse and the value of Romaine 

 and head lettuce for greenhouse culture was compared. The prepa- 

 ration of a monograph on varieties of lettuce was continued ; and the 

 influence of different top-dressings in growing carnations on raised 

 benches in greenhouses with reference to the keeping quality of the 

 flowers were studied. 



In animal husbandry, the results of feeding experiments with sheep 

 showed that the use of clover hay produced greater and cheaper gains 

 than the hay mixture ordinarily fed in the State; that turnips fed 

 with grain and hay appreciably reduced the cost of mutton produc- 

 tion ; and that silage Fas not as valuable as turnips as a feed for sheep. 



The entomologist demonstrated the possibility of controlling the 

 black fly in the "\Miite Mountains by treating streams where these 

 flies breed with a suitable soluble oil which kills the larvae without 

 injury to the trout in the stream. Studies were also made of leaf 

 hoppers, blister mites, and other insects. 



The station carries on cooperative experiments with farmers in the 

 hay-land improvement work, and with this department in testing 25 

 strains of soy beans with reference to period of maturity, yielding 

 capacity, habits of growth, and general adaptability. The study of 

 the nutritive ratio of corn and soy-bean silage mixed in the proportion 

 of 2:1, as compared with pure corn and pure bean silage, was also 

 pursued cooperatively. Part of the station work on soil potash is 

 in a measure cooperative with farmers. The station made examina- 

 tions of 238 samples of grass and grain seed and analyses of 135 sam- 

 ples of feeds and 110 samples of fertilizers for the State board of 

 agriculture. 



The following publications were received from this station during 

 the year: Bulletins 111, A Study of Farm Buttermaking in New 

 Hampshire ; 112, The Availability of the Soil Potash in Clay and 

 Clay Loam Soils; 113, The Codling Moth and How to Control It by 

 Spraying; 111, Some Apple Diseases; 115. Variety Tests of Oats, 

 Barley, AMieat. and Rye; 116, Analyses of Fertilizers; 117, Analyses 

 of Feeding Stuffs: Circular 7. Some Essentials in Farm Butter- 

 making; Scientific Contributions 3, The Oblique Banded Leaf 

 ■Roller — A New Insectary; 1, The Relation of Temperature to the 

 Growth of Insects; and the Annual Report, 1907-8.
