Report of Chemist, L. L. Van Slyke, Pit. D. (pp. 170-256).— 

 Tlie author entered upon liis duties July 12, 1890, succeeding E. F. 

 Ladd. 



Data obtained in connection with the test of breeds of dairy eoics (i)p. 

 171-242).— These data include analyses of the feeding stuft's used, e. g., 

 hay (timothy, red clover, clover and timothy, Kentucky blue grass, 

 barley, oat, oat and pea, etc.), oat and vetch forage, oat and pea for- 

 age, maize forage, altalfa forage, sorghum forage, maize silage, beet roots, 

 mixed roots, linseed meal, ground oats, wheat bran, wheat middlings, 

 cotton-seed meal, corn meal, grain mixtures, sweet milk, and skim milk; 

 a detailed record up to the last of November, 1890, for each cow of the 

 yield of milk and milk constituents, the composition of the milk, com- 

 l)osition of butter, creaming and churning data, and the percentage of 

 fat recovered and lost in butter making. Many of these data are incor- 

 porated in Bulletin Xo. 31 of the station (see Experiment Station 

 Record, vol. iii, p. 311). A description is given of the methods used in 

 creaming, churning, and sampling butter for analysis. 



Analyses of fertilizers (pp. 212-253).— Analyses of 69 samples of com- 

 mercial fertilizers. 



Experiments ivith methods of creaming (pj). 251-256). — The general 

 plan of a series of experiments commenced on this subject is discussed. 

 The data are reserved for a ftitiu-e bulletin. 



Report of Acting Horticulturist, C. E. Hunn (pp. 257-308, 

 plates 15). — The work of the year included tests of varieties of small 

 fruits and vegetables ; a comparison of imported vs. Ameri'can-grown seed 

 of cabbages and caulitlowers; a test of the relative yield of varieties 

 of tomatoes grown by diflerent methods of culture; a test of varieties 

 of potatoes, in connection with which an experiment was made on the 

 liability to decay of tubers taken from varieties subject to decay last 

 year as compared with tubers of varieties that were free from decay ; a 

 continuation of exi)eriments in cross-fertilization of fruits ; and notes 

 on insects and fungi and the means for their rejiression. 



Strawberries (j^p. 258-276). — Brief descriptive notes on 103 varieties 

 gro^\Ti at the station, with tabulated data regarding the prevalence of 

 blight on these varieties in diflerent years (1886-90), and descriptive 

 notes on 43 varieties grown at Pulaski, J^ew York, by L. J. Farmer, and 

 on 11 varieties grown at Rochester, Xew York, by Green's Xursery 

 Company. The results of experiments in crossing varieties are illus- 

 trated in 15 plates, accompanied by brief descriptive notes. 



"Of 1,000 seedlings fi'uiting during the seasons of 1888 and 1889, but 

 20 were saved as showing any indication of being of value. Of these 20, 

 15 have been discarded this season. Of 700 seedlings fruiting this year 

 for the first time, less than 50 have been noted as good enough to give 

 1 more year's trial." 



As shown in the illustrations, many of the plants resulting fi"om cross- 

 fertilization in 1890 produced fruits quite unlike those of either of the 

 parents.
