regions where agriculture is practicable, and it can not live on the kind of forage 

 which we feed to cattle and horses. Wherever the ground can be cultivated its 

 place will be taken by the horse and ox. But it is by far the most useful animal 

 for the region north of the agricultural belt. It is the means of transmuting a vast 

 amount of vegetation into meat and skins necessary to the support of the Eskimos." 



The Government's importation of camels: A historical sketch, C. C. Carroll 

 (U. S. Dept. Agr., Bureau of Animal Industry Rpt. 1903, pp. 391-409; Circ. 53, pp. 

 391-409). — A detailed account is given of the attempts which were made by the 

 United States Government from about the middle of the nineteenth century and later 

 to introduce camels into the southwestern United States. A number of importations 

 were made and the results obtained were fairly promising. Attention is also drawn 

 to the reasons which led to the final sale of the herd and the decline of interest in 

 the project. 



The poultry and egg industry of leading European countries, A. Fossum 

 ( U. S. Dept. Ayr., Bureau of Animal Industry Bui. 65, pp. 79).— Statistical and other 

 information is given regarding the number of poultry and the poultry and egg indus- 

 try in the principal European countries, attention being paid particularly to cooper- 

 ative poultry societies. In the appendixes the author gives the rules governing the 

 Society for Poultry Breeding in Denmark, the Society for the Promotion of Poultry 

 Breeding in Denmark, the Society for Profitable Poultry Breeding, and the Danish 

 Cooperative Egg Export Society. 



Imports of meat, meat products, eggs, and dairy products into the United 

 Kingdom, G. F. Thompson ( U. S. Dept. Agr., Bureau of Animal Industry Rpt. 1903, 

 pp. 452-465). — Statistics are given of the imports into Great Britain for 1901-1903, 

 inclusive. 



Imports and exports of animals and animal products, J. Roberts ( U. S. 

 Dept. Agr., Bureau of Animal Industry Rpt. 1903, pp. 466-518). — An extended com- 

 pilation of statistical data. 



Notes for preparing carcass pork, veal, and dressed poultry for market, 

 J. W. Sandford (Jour. Agr. and Ind. South Australia, 7 (1904), No. 12, pp. 687, 

 688). — Brief directions are given for dressing pork, veal, and poultry to meet the 

 demands of the local market. 



DAIRY FARMING— DAIRYING. 



Home-grown protein as a substitute for purchased feeds and tests of soil- 

 ing crops, C. F. Doane (Maryland Sta. Bui. 98, pp. 57-83). — Eight feeding experi- 

 ments with dairy cows, in which comparisons were made of leguminous crops and 

 commercial feeding stuffs as a source of protein, are reported. Brief notes on the 

 culture of alfalfa and cowpeas are included. 



Alfalfa hay and corn meal v. corn silage and mixed grains. — A ration made up of 

 silage prepared from well-eared corn and a grain mixture consisting of 3 lbs. of malt 

 sprouts, 1 lb. each of linseed meal, gluten meal, and corn chop was compared with a 

 ration of alfalfa hay and 7 lbs. of corn meal. The nutritive ratios were respectively 

 1:5.5 and 1:5.3. The test included 15 cows and covered 2 periods of 28 days each. 

 The results showed a considerable difference in milk production in favor of the 

 alfalfa ration. 



Alfalfa hay and corn silage vnthout grain. — Three cows previously fed on corn silage 

 and mixed grains were fed for 15 days a mixture of 10 lbs. of alfalfa and 20 lbs. of 

 corn silage, and for a following period of 15 days the former silage and grain ration. 

 Although the alfalfa and silage ration had a nutritive ratio of 1:5.5, it failed to give 

 as satisfactory results judged from the yield of milk as the silage and grain ration. 

 Apparently some concentrated food was necessary.
