In the .'is dairies from wliicli statistics were gathered tliere were in all 1,027 

 cows giving milk, an average of 21 for each dairy. These produced 1,582 gal. 

 of milk daily, or 1.54 gal. per day per cow, with an average of 4.54 per cent of 

 fat and S.9G per cent of solids-not-fat. The price of milk was 17 cts. per gal- 

 lon, making the income per day per cow 26 cts. The daily feed cost per cow was 

 12 cts., leaving a daily profit of 14 cts., not counting labor, interest on invest- 

 ment, insurance, or depreciation. 



Cost of producing milk, (J. A. Billings (New Jersey Stas. Rpt. J 907, pp. 79- 

 86). — Thirty-one cows comprising the herd during the year ending April 1, 

 ]!»07. produced on an a\erage per cow 6,288 lbs. of milk containing 4.3S per cent 

 of fat. 



•• Notwithstanding the advance in feed since 1906, the average cost of food per 

 cow for the year was $45.84, 3 cts. less than the average for the previous 

 year. This is explained by the greater amount of alfalfa grown on the farm, 

 and by the purchase of high* grade corn distillers' grains, in carload lots at 

 wholesale price. . . . 



" The feed cost of production of 100 lbs. of milk was 72.87 cts., of which the 

 roughage was 39.6 cts. and the feeds 33.2 cts. The cost of 1 qt. of milk was 

 1.5 cts. and 1 lb. of butter 14.27 cts." 



The cost of labor, interest, and decrease on herd per quart of milk is figured 

 at 1.48 cts., making the total cost of milk 3.04 cts. per quart. According to the 

 values calculated, " at 4 cts. a quart for the milk the farmer does not receive 

 full market rates at the present time for his hay or corn, even when no interest 

 is chai'ged on the investment in land and imjirovement." 



The unprofitable cow and how to detect her (Massachusetts 8ta. Circ. 12, 

 pp. .), Jigs. 2). — A brief explanation of the purposes and methods of cow-testing 

 associations. 



The progress of dairying in Canada (Rpt. Dairy and Cold Storage Conn: 

 Canada, 1907, pp. .'f-83, pis. 7). — A general discussion, including statistics, of 

 the cheese industry, the butter industry, sanitation in dairying, improvement of 

 dairy herds, and cow-testing associations. In connection with the latter topic, a 

 large numi)er of records of individual cows for 2 to 8 months are given, show- 

 ing the value of such accounts in the improvement of dairy herds. 



The data presented indicate that " in order to ascertain the value of a cow it 

 is necessary to test as well as weigh her milk. Frequently there is a gross dif- 

 ference of 50 lbs. of fat in the milk of 2 cows giving 4,.300 lbs. of milk each. 

 Many farmers are not only working hai"d but working overtime unnecessarily 

 keeping 12 cows when 7 would yield as much milk and butter fat. Cows of 

 mature age lower the average production of a herd just as often as heifers. 

 Many cows are evidently kept too long."

 Coinr. Canada, 1907, folio map). — A map showing the location of these estab- 

 lishments, to accompany the report of the dairy and cold storage conniiissioner.
