GENERAL OUTLOOK. 



The Pennsylvania Station has fontiiuu'd most of the investio^ations 

 that were in projfrcss at the* tinio of the hist report, and has i)ul)lished 

 some results which ha\-e attracted considerable attention. Tliis is 

 e.<<pecially true of the reports of experiments on milk substitutes 

 for cahe.'^, and the experiments in ginseng culture. The latter experi- 

 ments have shown on the one hand the possibility of securing large 

 returns from ginseng culture when carried on skillfully and painstak- 

 ingly, and, on the other hand, they have served to demonstrate the 

 exaggerated claims made by those who ha\'e seeds or plants to sell. In 

 the division of animal nutrition attention has l)een centered on work in 

 cooperation wdth the Bureau of Animal Industry of this Department 

 with the respiration calorimeter, which has been brought to a high 

 degree of perfection. After a number of very satisfactory preliminary 

 tests, actual trials with an animal were undertaken. An interesting 

 series of experiments has been completed, and a report of the results 

 is being published b}- this Department. In these experiments an 

 attempt was made to determine the relative value both for maintenance 

 and for productive purposes of corn meal as a representative of con- 

 centrated feeding stufis and of clover hay as representing coarse fodders. 

 The studies on the available plant food in soils in cooperation with 

 the lUireau of Chemistrv have been continued; also the tobacco inves- 

 tigations in cooperation with the Bureau of Soils, and a study of the 

 losses from manures under diiJerent conditions in connection with an 

 experiment in steer feeding in cooperation with the State department 

 of agriculture. The station has also ari'anged to cooperate with the 

 State department of agriculture and local grape growers in the north- 

 westei'n part of the State in a study of the diseases of fruits with 

 especial reference to the grape. The work in the division of dair^' 

 husbandr}^ has been restricted owing to the resignation of the dairy- 

 man, but a study of conditions determining the amount of moisture 

 in butter has been made. 



The last legislature inade an appropriation of $100,000 toward the 

 erection of an agricultural ))uilding for the college and sbition to cost
