212 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



Numerous lines of work were conducted with the Hatch fund, the 

 more important of which are here briefly enumerated. The chemist 

 made a study of the alkaline and neutral permanganate methods as 

 applied to vegetable and animal ammoniates, and the water-insoluble 

 nitrogen containing residues in commercial fertilizers. The work 

 was carried out in cooperation with the Rhode Island and Connecti- 

 cut stations, and the method worked out at the station was adopted 

 by all the New England stations. The veterinarian's work during 

 the year was mainly in connection with the continuation of the study 

 of infectious abortion in cows, and attention was also given to an 

 outbreak of malignant necrotic stomatitis in swine and calves. The 

 causal organism of this disease {Bacillus iiecrophorus) was isolated. 



In the forestry work were included experiments in the thinning of 

 white pine made in cooperation with agricultural students on land 

 belonging to the university. The horticulturist continued work on 

 scion selection to determine the value of scions selected from parents 

 showing high productivity. Inheritance studies with cucumbers 

 were conducted to observe the behavior of contrasting characters in 

 the future plants. The offspring of the original crosses during the 

 past year were in the third generation, and a strong, vigorous race of 

 new forms has been secured, but further tests are necessary to deter- 

 mine the permanency of structural characters. The results of a study 

 of plant diseases, occurring in 1910, as well as a compilation and 

 coordination of the results of 20 years' work along similar lines, 

 especially in relation to the weather, was issued as Bulletin 159 of 

 the station. 



The station performs practically no extension work, but has super- 

 vised periodic tests of pure-bred dairy cows. 



The publications received from this station during the year were 

 as follows: Bulletins 152, Commercial Feeding Stuffs — Principles 

 and Practice of Stock Feeding; 153, Plant Diseases— Potato Spray- 

 ing; 154, Commercial Fertilizers — Soil Classifications and Adapta- 

 tions; 155. Principles and Practice of Ice Cream Making; Circulars 

 4, Forest Nursery Stock for Distribution in the Spring of 1910; 5, 

 Concerning Bulletins 145, 147, 148, and 150; and the Annual Reports 

 for 1909 and 1910. 



The income of the station during the past fiscal year was as 

 follows : 



Unitea states appropriation, Hatch Act $15,000.00 



United States appropriation, Adams Act 15, 000. 00 



State appropriation 2, 142. 93
