476 EXPEEIMENT STATION EECOKD. [Vol. 38 



From a compilation of results at numerous experiment stations with nearly 

 GOO piKS tliose hand-fetl consumed an average of 5.47 lbs. of feed per head daily 

 and made an average daily gain of 1.23 lbs., while those self-fed ate 8 lbs. of 

 feed daily and made an average daily gain of 1.92 lbs. 



Several types of self-feeder.s are figured and described. 



Killing hogs and curing pork, F. G. Ashbkook and G. A. Anthony ( U. S. 

 Dept. Agr., Farmers' Bui. 913 {1911), pp. 39, figs. 22).— This publication treats of 

 home equipment for handling pork, and the killing, dressing, cutting, and curing, 

 including lard rendering, brine and dry curing, smoking, and sausage making. A 

 farm smokehouse is described, and a small ice house is figured and specifications 

 for its construction given. 



Standardized war rations for poultry, H. R. Lewis {Ncio Jersey Stas. Hints 

 to PouUrymcn, 6 {1911), No. 3, pp. 4).— The text is given of resolutions adopted 

 at a conference held in New York City November 22, 1917, by representatives of 

 the poultry departments of the colleges of agriculture of New York, Connecticut, 

 Massachusetts, and New Jersey. These resolutions urged the fixing of prices for 

 corn and the compulsory sale of cold-storage poultry products. 



The following standardized war rations for poultry were also approved : 

 (1) Scratch rations — cracked corn, feed wheat, heavy oats, and barley, 

 5:1:2:2; (2) mash — equal parts of wheat bran; wheat middlings; corn meal, 

 corn meal feed, or hominy; gluten feed; crushed or ground bone; and meat 

 scrap.

DAIRY FARMING— DAIRYING. 



The relation of the milk-vein system of dairy animals to production, A. W. 

 Aldeich and J. W. Dana {Vermont Sta. Bui. 202 {1911), pp. 3-24, fl&s. 3).— 

 Measurements were taken of the milk-vein systems of more than 600 cows in 

 the university herd and in the cow-testing associations of the State. These 

 were compared with the yearly milk and fat yields for as many years as there 

 were records. 



Measurements on a few cows were taken several times during the year to find 

 out how much variation there is in the same vein at different stages of the 

 lactation period. A slight increase was found in the size and crookedness of the 

 veins of some young cows after freshening but not enough to affect the outcome 

 appreciably. The age of the cow was not taken into consideration in making 

 up the tables. 



Correlation data on the different points compared are tabulated, and the 

 calculations in connection with one of the comparisons are given. It was found 

 that some degree of correlation seems to be traceable as between (1) the size of 

 the milk wells and the milk and fat yields, (2) the diameter of the milk veins 

 and the milk yield, and (3) body length and milk vein length. There also seems 

 to be some probability that cows showing forks or extensions of the milk vein 

 system may be better milk and butter producers than those not thus favored. 



The influence of the sire on the herd, J. H. AVilson {Vermont Sta. Bui. 202 

 {1911), pp. 39-44)- — During the 20 years in which the station herd consisted 

 essentially of grade Jerseys four pure-bred Jersey bulls were used. Data are 

 tabulated showing the production of the daughters of these bulls and of their 

 dams. Each bull at the time of purchase was thought to be a superior animal, 

 and from the standpoint of pedigree should have done good service. The four 

 methods used for comparing the production of the daughters with that of their
