made the better and more economical gains, from whicli it is concluded that 

 clover hay is the better roughage for fattening lambs. 



In the second experiment each lamb of lot 1 started with 10 oz. of grain 

 per day and each lamb of lot 2 with 6.4 oz., both lots finishing with 18 oz. per 

 lamb. During the period of the experiment the lot on the heavy grain ration 

 made an average gain per animal of 0.162 lb. daily, at a cost of 15 cts. per 

 pound ; that on the light grain ration averaged 0.126 lb. daily, at 17.9 cts. 

 per pound. 



A trial was made at Agassiz, B. C, of fattening ram and wether lambs on 

 rape. The lambs were pure-bred Dorset Horned, the rams being the better 

 individuals. The rape was only a fair crop and would support only 11 lambs 

 to the acre for 54 days. The lambs were run 14 days without grain and were 

 then fed 1 lb. each per day of a mixture of 4 parts whole oats, 2 parts crushed 

 barley, 1 part linseed oil meal, and 1 part corn meal. During the 54 days of 

 the test the rams made an average daily gain of 0.54 lb., at a cost of 4.6 cts. per 

 pound, the wethers a gain of 0.453 lb., at 5.6 cts. The value of an acre of rape 

 with the ram lambs was $17.97, with the wethers $14.03. 



Lamb feeding (Neto Mexico Sta. Rpt. 1917, pp. 85-87). — Tliis experiment 

 was made to determine whether lambs would make profitable u.se of weeds and 

 other roughage that usually go to waste, and also to determine the most 

 economical ration for finishing them for market. 



Rambouillet grade lambs, 168 in number, were run for 30 days in fields con- 

 taining cornstalks and weeds. Their gains during this period were small. They 

 were then divided into four lots and fed for 60 days. Three lots were fed 

 an average of 1 lb. of shelled corn daily and one lot 0.6 lb. All were fed 

 alfalfa hay, but in two lots part of it was replaced by corn silage. In one 

 lot a part of the shelled corn was replaced by corn silage. 



The results indicate that it is more economical to limit the grain ration apd 

 to feed corn silage in connection with the alfalfa hay. 



The agricultural situation for 1918. — I, Hog production should be in- 

 creased (U. S. Dept. Agr., Office Sec. Circ. 84 (1918), pp. 24, figs. 2).— Atten- 

 tion is called to the increasing needs of pork products to meet home demands 

 as well as those of our allies. While pork constitutes more than one-half of 

 the meats produced in the United States it furnishes also large supplies of fats, 

 the need for which is acute. During 1917 there was a decrease of 5,427,000 

 hogs, or about 7 per cent less than in 1916. The exports of pork products in 

 1917 were 1,417,000,000 lbs. 



To meet the demands 15 per cent more hogs are needed. There was an 

 increase in cereals during the year, much of which is available for pig feed, 

 of 836,624,000 bu. To encourage feeding the U. S. Food Administration fixed 

 a minimum price on hogs on the hoof at $15.50 per 100 lbs. at the stockyards. 



To further the production of pork it is recommended to preserve breeding 

 animals, to market hogs at heavier weights, to use self-feeders, and to feed 

 more wastes, such as city garbage. Pig clubs, swine breeders' associations, and 

 loans to pig feeders are indorsed. 



The more common diseases of the hog are explained, special attention being 

 given to the employment of the serum treatment for hog cholera. 



Swine, E. S. Archibald et al. {Canada Expt. Farms lipts. 1916, pp. 560- 

 573, 577-581, 583-597, pis. .i).— At the Central Experimental Farm an experi- 

 ment was carried out to determine the best method of feeding weanling pigs 

 10 weeks old or over during the summer. The pigs were divided into four lots of 

 eight or nine pigs each and the experiment continued 84 days. Lot 1 received 

 a mixture of equal parts of shorts, ground oats, and finely ground barlejs plus 

 skim milk. Lot 2 received the same feeds as lot 1 plus all the green clover they
