10 AGRICULTURAL EXPERIMENT STATION. [Jan. 



production of milk and of pork have been continued, with 

 some modifications ; to these have been added of late experi- 

 ments to ascertain the cost of feed for the production of beef 

 and mutton. A variety of field crops, in particular reputed 

 fodder crops, have been raised for testing their relative 

 feeding value, and to determine their general merits in a 

 mixed farm management. Some of these crops suffered, 

 in common with our grain crops, from exceptionally cool 

 and wet weather during the latter part of June and the 

 months of July and August. 



The la})oratory work has been exceptionally large and in 

 various directions, in consequence of the additional chemical 

 work called for by the Hatch Experiment Station, and by 

 the State inspection ctf commercial fertilizers ; aside from 

 the numerous applications of farmers, associations, and 

 parties interested in farming, for the examination of fer- 

 tilizers, fodder articles, well-waters, etc. 



The details of the work carried on in the previously stated 

 directions are recorded in the subsequent pages under the 

 following headings : — 



Feeding Experiments. 



I. Feeding experiments with milch cows, to ascertain the feed- 

 ing value of fodder corn, corn stover and corn ensilage, as com- 

 pared with English hay, and also of sugar beets and of carrots. 



II. Feeding experiments with milch cows, to ascertain the 

 value of a mixed crop of vetch and oats, of Southern cow-pea 

 and of serradella, when fed as green fodder in part or in the 

 whole for English hay. 



III. Financial record of twelve cows, kept at the Massaohu- 

 setts Experiment Station. 



IV. Creamery record of the station during the years 1887, 

 1888 and 1889 ; with some observations made during several 

 visits to the farms of one hundred and ninety-three patrons of two 

 creameries in our vicinity. 



V. Feeding experiments with pigs ; skim milk, barley meal, 

 corn meal, wheat bran and gluten meal serving as fodder ingre- 

 dients of the daily diet. 



Field Experiments. 



VI. Experiments to compare the effect of different forms of 

 nitrogen on the growth, etc., of corn.
