cow. Replajinj^ the 5 ponuds of linseed meal with 8 pounds of wheat bran the milk 

 yield was rather less on the whole, but in one case more than when linseed meal was 

 fed. The yield of butter was considerably diminished. 



The substitution of oats for the linseed meal was followed by a smaller milk yield 

 and less butter, but of superior quality to that from liuseed-!iieal food. 



The experiments with silage and cotton-seed meal have not been repeated a snffi- 

 cient number of times to warrant any definite conclusions. With silage the chief 



difference noted was the more efficient recovery of the fat in the butter, and the but- 



t 



ter under cotton-seed meal was of much better quality than when linseed meal was 

 fed. * » » 



Of all grain foods tried, gluten meal gave the largest flow of milk, but the percent 

 of fat was exceptionally low. Dry feed, a waste product from the manufacture of 

 starch and glucose from corn, ranked next to gluten meal. Corn meal followed these 

 for producing flow of milk. Linseed meal gave the largest amount of butter, but the 

 quality was not of the best, being too soft. Oats gave the best-colored and hardest 

 butter, but somewhat crumbly. A combination of foods was the most satisfactory 

 butter ration. 



In the feeding trials made with five individual animals we find that the character 

 of the food did largely influence both the yield of butter and the qiiality.

 The following topics are treated: grass plats and forage crops; potato 

 experiments; fertilizer experiments with corn; corn in hills, drills, and 

 broadcast; variety tests of corn, beets, and carrots; fertilizer experi- 

 ments with grass ; relative yields of four varieties of barley ; warm 

 water for milch cows; snbsoiliug experiments; the mannre platform. 



Grass plats and forage crops (pp. 216-223). — Notes In continuation 

 of those in the Annual Report of the station for 1888 (See Experiment 

 Station Bulletin No. 2, p. 164). The number of different grasses, clovers, 

 and other forage plants grown at the station on small plats was 

 increased in 1889 so as to include some 65 species and varieties. In 

 addition to the species especially recommended in the Report for 1888, 

 meadow foxtni\{ Alopecurus prateiisis), orchard grass {Dacfylis glomcrata), 

 tall meadow oat grass {Avena elatior), yellow oat grass [Avena Haves- 

 cens), and sheep's fescue {Festuca ovina) for pasturage, and the rye 

 grasses {Lolium paceyii and L. perenne) have given good results. 



Tabulated data are given for the yields in 1889 of mixtures of forage 

 plants seeded on large plats in 1886. The best yields were on the plats 

 where (1) alsike clover, perennial rye grass and timothy; and (2) 

 meadow fescue, timothy, Kentucky bine-grass, and white, alsike, and 

 red clovers were the leading plants. The yields of alfalfa and prickly 

 comfrey in 1889 are given in a separate table. In 1889, as in the pre- 

 vious year, ])rickly comfrey did not make good silage or hay. Alfalfa, 

 however, was the main-stay as a soiling crop, " having been the first 

 thing ready to feed in the spring, and the fourth crop the last in the fall." 

 [For the results of 7 years' experience with alfalfa at this station, see 

 Bulletin No. 16 of the station, or Experiment Station Record, Vol. I, 

 p. 266.] 



The kinds and amounts of seed used in a new series of mixtures of 

 grasses sown in the spring of 1889 are stated in a table.
