494 EXPERIMENT STATION RECORD. 



separated into 5 lots, was conducted by the author for the purpose of determining 

 the comparative value of distillery pulp and beet pulp as feeds for milch cows. 



The distillery pulp was obtained from § potatoes and J Indian corn. Chemical 

 analysis showed it to vary considerably in composition, the water content of seven 

 samples ranging between 91.67 and 95.80 per cent, and the protein content between 

 1.20 and 2.25 per cent. The average composition was as follows: Moisture, 93.79 per 

 cent; fat, 0.33 per cent; crude protein, 1.62 per cent; carbohydrates, 3.65 percent; 

 ash, 0.61 per cent; acidity (calculated as lactic acid), 1.27 per cent. 



The experiment was continued for 71 days, separated into 3 periods, of which the 

 second was the experimental period proper of 30 days' duration. The results indi- 

 cated that 14 kg. of distillery pulp fully took the place of 13 kg. of beet pulp. In a 

 ration low in protein, 14 kg. of distillery pulp could not, however, take the place of 

 1 kg. mixed concentrated feed (sunflower-seed cakes, cotton-seed meal, and wheat 

 bran, fed in the proportions of 0.4:0.4:2.5). This was, on the other hand, appar- 

 ently the case when a ration rich in protein was fed. — f. w. woll. 



Dairy herd record, W. J. Elliott (Montana Sta. Rpt. 1904, pp. 207-210). — Rec- 

 ords of 6 cows for 1 year are reported and comments made thereon. 



The discussion of the milk problem from the standpoint of production, 

 C. E. Maeshall (Michigan Sta. Bui. 228, pp. 185-195). — Among the features of the 

 problem considered are the cost of milk production, the ability of individual farmers 

 to produce milk profitably under conditions fulfilling the requirements of the sanita- 

 rian, the unwillingness of consumers to pay extra prices for pure milk, the ignorance 

 of consumers and even milk inspectors concerning milk production, the proper hand- 

 ling of milk, etc. 



It is estimated that 12 cts. per quart is not too high a retail price for milk w T hen all 

 the conditions under which it is produced and handled are ideal. The author does 

 not believe that 1 per cent of the farmers are capable of producing milk profitably 

 in a pure form. He argues for the production and sale of milk of different grades on 

 a business basis. Such specifications as seem fair for the production of 5-cent milk, 

 6-cent milk, and so on, should be agreed upon by contract between producer and 

 consumer. 



The producer should decide upon what grade of milk he is willing to produce. The 

 consumer should understand clearly the difference between, say, 5-cent milk and 

 10-cent milk and should decide what grade he wants. The inspector specially 

 trained for this purpose should merely see that the specifications are fulfilled. Forty- 

 one specifications are enumerated, all of which it is believed should be embodied in a 

 contract for the best grade of milk. 



Scheme for the sanitary control of the municipal milk supply, G. W. Goler 

 {.liner. Med., 10 (1905), Xo. 17, pp. 696-699, dgms. 3) .—A brief account is given of the 

 establishment and development of the Gouttes de Lait, or infants' milk depots, 

 which, it is argued, should now be aided and extended by the State instead of by 

 private philanthropy. 



The plan of municipal control presented provides for a chief sanitary officer and 

 advisory board for the Gouttes de Lait, an advisory board or milk commission for the 

 general milk supply, and a bureau for inspection and laboratory examination. With 

 some modifications, this plan has been in operation in Rochester, N. Y., and some 

 of the results there obtained are here presented. For several years the effort has 

 been made to secure a municipal standing of 100,000 bacteria per cubic centime- 

 ter. The average number, however, during 1904 was 253,727. Of the total samples 

 examined, 47 per cent contained less than 100,000 bacteria per cubic centimeter. 



A study of the milk supply in New York, S. W. S. Toms (N. Y. State Jour. Med., 

 5 (1905), No. 9, pp. 336-344). — The author discusses the subject of milk contamina- 

 tion, reports upon the condition of a number of dairies inspected by him, and gives 

 the regulations and rules for the production and sale of milk in Rockland County.
