and cooperative work in dry farming was carried on. Most of these 

 experiments were interfered with by an early frost which damaged 

 the crops. This department made tests of about 75 varieties of 

 grass, grain, and vegetable seeds during the year. 



In animal husbandry, feeding experiments were made with lambs 

 and an account of the work was prepared for publication. The lambs 

 were fed in five lots of 32 each and corn alone was compared with 

 linseed-oil cake against alfalfa meal combined with corn. A number 

 of digestion experiments were made to determine tlie coefficients for 

 Wyoming forage plants. A coop^ative breeding experiment with 

 polled Hereford cattle and pasture experiments with alfalfa, peas, 

 rape, and similar crops for pigs were in progress in cooperation with 

 the station chemist. 



The forage-plant investigation b}' the chemist, which was closed 

 earh' in the year, was a continuation of an earlier study to determine 

 the chemical composition of some of the native forage plants of the 

 State, but in the more recent work account was taken of the effect 

 of altitude upon the composition of the plants. It was observed in 

 general that the crude protein and nitrogen-free extract content of 

 forage plants increases while the percentage of crude fiber decreases 

 with an increase of altitude. The relation of organic matter to bac- 

 terial activity in soils was also studied, and while considerable work 

 has been done conclusions have not yet been drawn. 



The irrigation engineer completed a study of the reclamation by 

 means of underdrainage and leaching of a badly water-logged and 

 alkalied portion of the stock farm, and made a report upon this work. 



The station veterinarian, in addition to cooperative and other 

 Adams fund work, prepared over 600 tissue specimens obtained from 

 the season's post mortems, and the study of these was carried on as 

 rapidly as time permitted. Various inquiries were made during the 

 year as to the manufacture and distribution of vaccines by the station 

 for prevention of disease, and some few vaccines of both the stock 

 and autogenic types were prepared. 



The station undertook little cooperative and extension work during 

 the year. One demonstration farm, located at Wheatland, was super- 

 vised by the station and conducted with funds from private sources, 

 A large amount of machinery was loaned by manufacturers for use in 

 demonstration work and also in the experimental work upon the 

 station farms. 



The publications received from this station during the year were 

 as follows: Bulletins 85, Feeding Experiments, 1909-10; 8G, Pota- 

 toes; 87, Wyoming Forage Plants and Their Chemical Composition — 

 Studies No. 4; 88, Woody Aster; and the Annual Report for 1910.
