Rocks, White Orpingtons, and Buffi Orpingtons. The Ancona pen started with 

 6 birds, the others with 12. The number of birds was reduced from 90 to 87 

 in the second year and to G7 in the third. The average egg production of the 

 pullet year was 72.17 eggs per hen, of the second year 61.48 eggs, and of the 

 third year 50.53. Fourteen Plymouth Rocks were retained for a fourth year 

 and produced 24.57 eggs per hen. The birds of the Mediterranean class laid 

 more' consistently througliout the Hv^t three years than did the Plymoutli 

 Rocks or the Orpingtons. 



The percentage production of each pen by months is also tabulated. The 

 older birds showed a greater decrease in winter tlian in sununer production. 



Artificial illumination of poultry houses to increase fall and winter egg 

 production, V. G. Aubry (Neiv Jersey Stas. Hints to Poultry men, 7 (1919), 

 No. 10, pp. 4). — The management of laying hens when winter days are artifi- 

 cially prolonged by the use of electric lights or other sources of illumination 

 is briefly outlined. It is pointed out that no mystery attaches to this much 

 discussed method of increasing egg production ; the birds merely have more 

 time to eat. 



How to prevent loss in market eggs, G. H. Pound (New Jersey Stas. Hints 

 to Poultrymen, 7 {1919), No. 9, pp. 4). — Notes on the grading, handling, and 

 packing of market --eggs are given. It is f^tated that poultrymen in Petalunia, 

 Cal., because of the attention they give to these matters, are able to undersell 

 New Jersey poultrymen in the wholesale fancy egg market of New York City. 



DAIEY FAEMING— DAIRYING. 



Experimental feeding' [of dairy stock], G. A. Langelier (Canada Expt. 

 Farms Rpt. 1918, pp. S8, 89). — Experiments conducted at Cap Rouge, Que., are 

 reported. 



A group of 3 calves reared mostly on skim milk and a home-made calf meal 

 composed of corn, oats, and flaxseed (4:2:1), consumed in the first 24 weeks 

 after birth 89.5 lbs. of whole milk. 2,322 lbs. skim milk, 260 lbs. of the meal, 

 220 lbs. of hay, 103 lbs. of roots, and 15 lbs. of silage per head. 



Continuing work previously noted (E. S. R., 40, p. 775) the average feed 

 consumed by :i heifer until calving time (about 28 months) was found to be 

 892 lbs. whole milk, 7,553 lbs. skim milk, 764 lbs. meal, 2,910 lbs. hay, 5,590 

 lbs. roots, 6,074 lbs. silage, 181 lbs. green feed, and 94 days of pasture. 



A group of milch cows allowed an unlimited grain ration consumed a pound 

 of meal for each 2.18 lbs. of milk produced. The profits (on a 1913 price basis) 

 were greater than those from two other groups i-eceiving a pound of meal, 

 respectively, for each 4 and for each 8 lbs. of milk. 



There is also a note on the growth of two heifers, twin sisters, one fed a 

 heavy ration, one a liglit one. 



Report on calf-feeding experiments conducted at the college farm, Kil- 

 marnock, in 1916 and 1917, W. G. R. Paterson (West of Scot. Agr. Col. Bui. 

 SJf (1918), pp. 13-23). — To study economical methods of rearing calves in cheese 

 making districts, 32 Ayrshire calves were fed during the course of the two 

 years' experiments. It was found that the gradual i-eplacement of whole milk 

 by whey between the third and sixth week and then the feeding of whey with 

 grain or other concentrates resulted in calves practically as thrifty and as well- 

 grown as the check lots fed skim milk and crushed oats. The concentrates 

 fed with the whey included (1) oat meal and fi:<li meal, (2) palm-nut meal, 

 and (3) fine middlings nnd fish meal. 



The escutcheons of dairy cows, J. J. Hoopku (Breeder's Gaz., 76 (1919), No. 

 2, pp. 52, 53).— A brief discussion is given of tlie escutcheons of 1,019 dairy
