580 EXPERIMENT STATION KECORD. 



these requirements were not fulfilled the judges regarded the methods 

 of A. H. L. Horn, Gerber. Krugmann, and Lindstrom as about equally 

 accurate and of value for the use of the farmer. They recommend 

 that each be awarded 500 marks. The detailed results of the tests ot 

 the methods are promised later. 



Pasteurization of cream, H. Appel {MalJceritid., 7 {1894), p. 42S). — 

 At the Randers (Denmark) Agricultural Fair in June, 1894, 250 entries 

 of butter were made, 120 of which were made from pasteurized cream, 

 and 130 from unpasteurized cream. Of the butter made from pasteur- 

 ized cream 32.5 per cent was awarded premiums, as compared with 5.4 

 per cent of butter made from non-pasteurized cream. — F. w. woll. 



Dairy calendar for 1895, F. W. Woll (Netv York: John Wiley 4- Sons, 1895, pp. 

 S27). — This little book is on the plan of the German agricultural calendars, but is 

 even more comprehensive and practical. One-half consists of a diary, and the 

 remainder of condensed information on breeds, milk, cream, butter, cheese, feeding, 

 general tables, statistics, and a directory of dairy associations, commissioners, 

 schools, institutes, etc. As a reference book for dairymen, butter and cheese mak- 

 ers it deserves commendation. It is to be welcomed as a valuable addition to our 

 rapidly growing literature of jiractical dairying.

AGRICULTURAL ENGINEERING. 



Frequency of irrigation, J. W. Sanborn ( Utah Sta. Rpt. 1893, pp, 

 86-94). — This is an account of a continuation in 1893 of experiments 

 described in the Annual Report of the station for 1892 (E. S. E., 4, p. 

 87). Plats of wheat, timothy, and clover on gravelly upper bench 

 soil were irrigated at intervals of 3, 6, 9, 12, 15, and 18 days, the total 

 amount of water applied to each plat during the season being the 

 same. In experiments on wheat during 4 years the best average 

 results were obtained by irrigating every 9 days. Timothy did not 

 appear to require so frequent irrigation. For clover irrigation every 

 16 days gave the best results. 



Observations on the temperature of the soil of the different plats 

 before irrigating, 2 hours after, and 1 day after indicated that the less 

 frequent the application of water the higher the temperature of the 

 soil (the difference amounting in some cases to about 10° F.).
