basis of the hypothesis that the White Leghoi-n carries in itself all the factors 

 for black pigmentation, the actual and expected results corresponded veiy 

 closely. 



The results of this study indicate that the admixture of 'Leghorn blood can 

 not be made without introducing complexities in either pattern or color. 



Seaweed for packing birds, M. Dekobka {Nature [Paris], J,2 {101 Jf), No. 

 2134, pp. 339-340, figs. 5; al)s. in Internat. Inst. Agr. [Rome], Mo. Bid. Agr. 

 Intel, and Plant Diseases, 5 {1914), No. 7, p. 918). — ^A new method of packing 

 birds is described, which consists " in placing the body in a natural bag formed 

 by the lamina of a certain seaweed occurring in islands off New Zealand. 

 Birds can be kept in good condition for several years in this way." 



DAIRY FARMING— DAIRYING. 



Beport of the dairy husbandry department, O. F. Hunzikee {Indiana Hta. 

 Rpt. 1914, pp. 37-47) I — In continuing Avork previously noted (E. S. R., .30. p. 

 575) three lots of five cows each were fed for six months corn silage and alfalfa 

 as roughage and a grain rating as follows: Lot 1, corn meal, wheat bran, and 

 cotton-seed meal 4:2:1 by weight ; lot 2, ground corn and wheat bran 1:1; 

 lot 3, ground corn and oats 1 : 1. The gains in weight per head were, respec- 

 tively, 19.64, 19.8, and — 7.56 lbs., the milk yields approximately 1,435. 1,400.7, 

 and 1.430 lbs., the milk fat yield 57.6, 56.72, and 56.86 lbs., the total dry matter 

 consumed per pound of millv 0.97, 0.99, and 0.94 lb., and the average daily 

 cost of feed 21.1. 20.7, and 20.5 cts. per head. The cost per pound of fat was 

 22.1, 22.2, and 22.5 cts., respectively. 



It is concluded that the use of wlieat bran or ground oats in a dairy ration 

 Is to be recommended, although the selection should depend largely upon its 

 availability. 



In an experiment in which three lots of six or seven calves were fed for 42 

 weeks as follows: Lot 1, an average of 11.2 lbs. skim milk per head per day; 

 lot 2, 1.41 lbs. per day of home-mixed calf meal consisting of hominy meal, 

 linseed meal, red dog flour, and dried blood equal parts by weight; and lot 3, 

 1.06 lbs. per day of a commercial calf feed, all of the lots receiving whole 

 milk until gradually displaced by the other feeds, and also receiving a dry 

 mash and a roughage feed of alfalfa hay and silage, the average daily gains per 

 head were 1.26, 1.04, and 0.78 lbs., the average daily cost of the ration 7.1, 

 7.4, and 9.67 cts., and the cost per pound of gain 5.6, 7.2, and 13.6 cts., respec- 

 tively. This experiment is being continued. 



In ox'der to determine the accuracy of the different methods of sampling 

 milk, including daily samples, composite samples with aliquot portions or equal 

 portions, samples every second day, every third day, every fourth day. and 

 evei'y fifth day. tests were made of 4,900 of samples taken by these methods. 

 The averages of the percentages of fat and pounds of fat of all samples and for 

 the entire 14 days show " a remarkable uniformity of results secured by the 

 several methods." 



Beport of an experiment on the feeding' of dairy cows, T. ^Milbubn and R. 

 Richardson {County Council Lancaster. Ed. Com., Agr. Dept., Farmers^ Bnl. 28 

 {1915), pp. 13). — An analysis of palm-nut cake is given as moisture 12.29. pro- 

 tein 18.79, fat 6.87, carbohydrates 48.84. fiber 9.51, and ash 3.7 per cent. 



Two lots of six cows each were fed by the reversal method for two months a 

 basal ration of roots, meals, and hay, lot 1 receiving daily in addition from 4* 

 to 5 lbs. of decorticated cotton cake, and lot 2 from 6J to 7* lbs. of jxilm-nut 

 cake. The cotton-cake fed lot yielded a total of 8,852 lbs. of milk during the
