978 EXPERIMENT STATION RECORD. 



A method of milk production, C. E. North (Med. Rec. [N. Y.], 73 (1908). 

 No. 7, pp. 263-2S(i). — The author found from experience, which he describes, 

 that " the use of sterile covered pails and sterile millv cans by the ordinary 

 farmer will immensely reduce the bacteria in his milk, even though no other 

 sanitary precautions are taken." He suggests that since the farmer has not 

 facilities for proper sterilization of his milk utensils it is desirable to " increase 

 the functions of the creamery, so that it becomes a washing and sterilizing 

 plant for all the milking pails and milk cans of all the farmers contributing 

 milk to it." The creamery should require its patrons to use only those utensils 

 and to deliver 'the milk twice a day. "The dairy house, where wa.shing and 

 sterilizing of utensils and cooling and bottling of milk are done, may be at a 

 distance of several miles from the cow stable without materially increasing the 

 bacterial count, provided the milk is delivered at the dairy house within one 

 hour after milking." 



The hygienic and economical production of milk for infants, Pusch 

 (Ztschi: Infekfionskraiik. k. Hijg. Haustiere, 3 (1908), No. 5, pp. J,01-J,69, figs. 

 10). — This is to a large extent an account of experience at the veterinary high 

 school in Dresden. The health of cows, their care and feeding, and methods of 

 milking and handling the milk are discussed. 



Inspection of dairies, C. Harrington {Ann. Rpt. Bd. Health Mass.. 38 

 (1906), pp. 4/5-^27, pis. 14). — Of the 3,421 dairies examined by the veterinarian 

 employed by the board for this purpose, 1,004, or 31 per cent, were found to be 

 without objectionable feature. The attention of the proprietors of the remain- 

 ing 69 per cent of the dairies was called to the objectionable conditions, the 

 great majority of which were stated to be susceptible to correction at little or no 

 expense. The report states that the results, while not all that could be wished, 

 have been very encouraging for hopes of success in the efforts to improve the 

 condition of the milk supply. The nature of the defects to which attention was 

 called is explained and illustrated. 



Milk supply of Chicago and twenty-six other cities, J. M. Trueman (Il- 

 linois Sta. Bui. 120, pp. Jfl-70). — The principal feature of this bulletin is the 

 report of results of a 7 months' study of the conditions under which milk is sold 

 in Chicago, in which about 1,100 samples were collected and analyzed by the 

 author. In addition to that, the conditions in 26 other cities of 10,000 or more 

 population are discussed. 



The data reported show chiefly the percentage of fat and the amount of sedi- 

 ment in the milk, and the results of examination by the Wisconsin curd test. 

 Considerable difference was found in the quality of the milk bought in differ- 

 ent sections of Chicago. In the better portions of the city the milk was uni- 

 formly up to grade in butter fat, the data reported showing that of 95 samples 

 from one such district only 9 per cent were below standard grade in this respect. 

 On the other hand, in poorer sections of the city the quality of the milk was not 

 so good. In one section, of 413 samples tested 32 per cent were below the legal 

 standard of butter fat, and in another section, of 150 samples collected 50 per 

 cent were below the standard. The larger portion of the milk throughout the 

 city also contained considerable quantities of sediment. 



Of the milk collected in the smaller cities over 19 per cent of the samples 

 were found to be below the legal standard of butter fat, and 63 per cent were 

 below the legal standard for total solids. 



Market milk, bacteriological data, F. L. Stevens (CentU. Bakt. [etc.], 2. 

 Abt., 20 (1907), No. Jf-5, pp. lL'f-121). — The data reported were accumulated 

 during a routine examination of 235 samples of the milk of Raleigh, in continu- 

 ation of work previously reported (E. S. R., 17, p. 1006).
