There was much improvement in the affairs of the Oregon station 

 during the past year, and a much hirger amount of experimental 

 AYork was done than formerly. The generous appropriations from 

 the State have been of great assistance, and show the interest and 

 sympathy in the work of the station.

The staff of the Pennsylvania station was strengthened during the 

 year by the addition of a large number of assistants in different de- 

 partments. Otherwise there were few changes of importance on the 

 staff. The facilities for investigation were increased by the con- 

 struction during the year of an open shed suitable for conducting 

 experiments with a comparatively large number of steers, and by 

 the renting of an additional farm, which made possible the con- 

 struction of an open shed for milch cows, A series of six lots 

 adapted to experimental work in fattening hogs was also provided 

 on this farm. The construction of two ranges of greenhouses, each 

 30 by 100 feet, with a suitable head house, added to the facilities of 

 the department of horticulture. 



As in previous years, the Adams fund was used principally in 

 three general lines of investigation, conducted by the Institute of 

 Animal Nutrition, the department of experimental pomology, and 

 the departments of experimental chemistry and agronom3\ The 

 studies of the effect of fertilizers, manures, and lime on the soil and 

 crops in the long-term rotation plats were continued, partly in co- 

 operation with this department, and certain parts of the work were 

 completed. The results secured have been embodied in 24 papers, 

 which have appeared for the most part in the last four annual re- 

 ports of the station. Fertilizer experiments similar to those on the 

 rotation plats have been laid out on permanent pasture and the 

 different lines of investigation were extended to these plats. 



The year's work on the animal metabolism project was mainly 

 along the line of making improvements in accessory features of the 

 respiration calorimeter and in working up the results of previous 

 work. 



The investigations on the causes affecting yield and quality of 

 apples were extended to include 12 orchards, covering 91 acres in 

 different parts of the State, besides the new 29-acre station orchard. 

 The results thus far secured in these investigations indicated nitro- 

 gen to be the limiting factor in apple-orchard fertilization. Experi-
