The monthly averages for each year of milk and cream produced by 

 the station herd, the cost of food, receii)ts for cream, and the cost of 

 the skim-milk with whole milk at 3 cents per quart, are given below. 



Aceragc per month. 



The net cost of food in this case refers to the total cost, less the value 

 of the fertilizing constituents contained in the cream, which was calcu- 

 lated from the average of several analyses. " In selling cream miicli 

 less fertilizing constituents are lost to the farm than in selling the whole 

 milk. * * * The cost of skim-milk varied considerably during 

 ditiercnt months of the year, mainly on account of the changes in the 

 valuation of the cream. * * * xije feeding value of skim-milk 

 containing 9.5 per cent solids, as compared with whole milk, is stated by 

 good authority to be as 3,1 to 4. On this basis, with whole milk selling 

 at 3 cents per quart, skim-milk would be worth 2.33 cents. The feed- 

 ing value of skim-milk, estimated on the customary basis of 4.33 cents 

 per pound of digestible nitrogenous substances and fat, and .9 cent for 

 noniiitrogenous substances, would amount, per gallon, to 1.91 cents." 



(5) Some facts conerrning two creameries (pp. 81-102). — This is mainly 

 a statement of the number and breed of cows kept, the rations fed, aud 

 the cream produced by each of 193 patrons of two creameries, and a 

 statement of totals and averages for the whole number. Analyses are 

 also given of numerous samples of butter and cream from each creamery, 

 analyses of cream from the station dairy, and a summary of the butter 

 and cream analyses. 



Feedino experiments with pigs, C. a. Goessmann, Pir. I), dip. 

 103-123). — A short discussion of the feeding experiments with pigs 

 made at the station since 1884, including a tabulated summary of the 

 results ; and a report of the tenth experiment in this line, made in 1889. 

 The latter was made with seven grade Chester White and Berkshire 

 pigs, weighing from 14 to 23 pounds each at the beginning of the ex- 

 periment, and extended from April 23 to August 28, 127 days. It diflfers 

 from the i)revious trials mainly in the substitution of barley meal for the 

 corn meal. About 5 (piarts of skim-milk daily were consumed by each 

 pig during the whole trial. Two ounces of barley meal added to each 

 quart of skim-milk fed, supplemented as needed by a mixture of two 

 weight parts of glnteu meal aud one of wheat brau, made up the ration
