date. The analyses show, vnth reference to the composition of the corn 

 at different dates, that — 



(1) The percentage of water in corn fodder cut August 2G was considerably greater 

 than that in the samples taken September 19. 



(2) The percentage of ash in the dry matter decreased materially as the plant 

 matured. 



(3) The percentage of albuminoids had decreased slightly in the dry matter during 

 the period of growth between August 26 and September 19. 



(4) The percentages of fat, fiber, and carbohydrates had increased during the same 

 period, the two former, however, not to any marked extent. 



The analyses of silage show a slight increase in the percentages 

 of protein, fat, and cellulose, and a decrease in carbohydrates from 

 December 4 to March 5. 



Report on the progress of the -work of the experimental farms 

 of the Dominion of Canada, W. Saunders {Canada Central E.rpt. 

 Farm Bid. Xo. 13. June 3, 1891, px). 16). — An outline of the work of the 

 experimental farms during 1890 presented to the Committee on Agricul- 

 ture and Colonization of the House of Commons of the Dominion of 

 Canada. Details of this work were published in the Annual Eeport 

 of the experimental farms for 1890. 



Variations in the fat of milk drawn from the bottom of the can, 

 H. H. Dean {Ontario Agr. CoUege Uxpt. Sta. Bid. Xo. 66, June :J8, 

 1891, pp. 7). — These tests were undertaken to determine whether or 

 not, in delivering milk to customers by drawing it through a faucet at 

 the bottom of the can, there is a difference between the milk served 

 first and that drawn last, so that each customer does not get his fair 

 share of fat. Tests were made by the Babcock centrifugal method of 

 the fat in milk drawn by four different milkmen at different intervals 

 during the delivery. The tabulated results show practically no differ- 

 ence in the percentage of fat in the milk drawn from the same can at 

 different times, the variations noted being all within the errors of 

 analysis liable to occur with the method emijioyed. 



Winter- wheat experiments, T. Shaw and C. A. Zavitz {Ontario 

 Agr. GoUege Expt. ^ta. Bid. Xo. 67, August 12, 1891, pp. i5).— Tests 

 were made of 51 varieties, 24 Canadian and American, and 27 foreign. 

 ISTone of the foreign varieties proved equal to the others. Tabulated 

 data are given for 23 of the Canadian and American varieties. 



(1) The bald wheats have given on an average 9.86 bushels or 21.42 per cent more 

 per acre than the bearded varieties, but the latter have weighed on an average 1.37 

 pounds more per bushel. 



(2) The white wheats have given an average of 5.18 bushels more per acre than 

 the red wheats, and they also stand higher in the estimation of the millers than the 

 latter. 



(3) The bald white chaff white wheats gave an average of 13.6 bushels per acre 

 more than the bearded red chaff red wheats. 



(4) The seven leading varieties in point of yield were all white wheats except the 

 American Bronze. 



(5) The four best-yielding white wheats for 1891 were the Garfield [64 bushels per
