not more tliaii $^50,(»0(). The \vin»^' provided for in tliis appropriation 

 is to ])e devoted to dairvin<i- and is now api)roacliing completion. The 

 completed aoricultural ])uildin<^- will include not only this dairy build- 

 mg }>ut also the respiration calorimeter building which was completed 

 several years ago. 



The Pennsylvania Station is very much in need of additional funds to 

 develop its scientific investigations. During the past 3^ear the respira- 

 tion calorimeter, representing an investment approximating !^15,0»M), 

 was in actual use less than 300 hours, owing to the fact that there 

 were not funds to provide sufficient help to carry on investigations 

 with this apparatus while investigations were going on in other divi- 

 sions of the station. This is one of the very important lines of investi- 

 gation in animal husbandry in this country and adequate funds should 

 be provided for its support. There is also need of additional funds 

 for a systematic study of the soils of the State and for investigations 

 to aid in the development of the horticultural and poultry interests. 

 The appropriation ahead}' made for the college and station, while it 

 will not directly relieve the station, is very encouraging, owing to the 

 fact that it was secured by the united and persistent demands of the 

 agricultural interests of the State. It is hoped that these interests 

 will contituic to demand recognition through increased appropriations 

 for the investigation of problems aftecting them. 



LINES OF WORK. 



The ])riiicipal lines of work conducted at the Pennsylvania Station 

 during the past year were as follows: Chemistry — cooperation with 

 other departments in the study of foods, feeding stuffs, excreta, fer- 

 tilizers, and agricultural products, miscellaneous anal3'tical work, 

 study of chemical changes in vinegar and vinegar solids, and of varia- 

 tions in the composition of milk, experiments with tobacco, referee 

 work for the Association of Official Agricultural Chemists of the 

 United States; meteorology; analysis of fertilizers, foods, and feed- 

 ing stuffs; horticulture — variety tests of small fruits, experiments 

 with crown gall of fruit trees, growing ginseng; field experiments — 

 rotation experiments with fertilizers on 144 plats, rotation of legumes 

 for soiling purposes, variety tests of farm crops; feeding experi- 

 ments — investigations in animal nutrition in the respiration calorim- 

 eter, feeding steers and correlated chemical studies on the relative 

 losses from the manure of fattening cattle under different conditions 

 of feeding; dairying — building up a herd from common stock, feeding 

 dairy cow's, study of the effect of keeping drinking water constantly 

 before cows, effect of variety in the grain ration of cows, experiments 

 to tost the value of a home-mixed calf meal as a substitute for milk in
