screoninjis consi^^t of alfalfa seeds, clover seeds, and vaiioiis weed seeds; while sereeu- 

 ings No. 2 was made up mostly of eracked, l>rokeii and shrunken wheat. At the 

 beginnin-; of the test, which covered 14 weeks, the average weiglit of the hunlxs was 

 about 47 lbs. each. On good wheat the average daily gain wa.s 0.19 lb., and on 

 frosted wheat 0.21 lb.; on No. 1 screenings, 0.21 1))., and on No. 2 .screenings 0.24 11)., 

 while 4.54, 4. U), 5.o2, and 4.38 lbs. of the grains were required per pound of gain, 

 respectively, in addition to about 62 lbs. of alfalfa. The cost of food eaten i)er ]>ninid 

 of gain in the 4 lots was 4.88, 4.18, 3.24, and 3.95 cts., respectively. 



"Taking into account both the rate and the cost of the gains, the results of this 

 experiment indicate that it is more profitable to feed screenings than either good or 

 frosted wheat." 



The composition of the different grains fed is reported and tlu' work 01 the Cana- 

 dian stations in feeding frozen wheat cited in some detail.

 (Jour. n<J. .[(jr. [Londoti], 7 {1900), No. -?, /»75. .?/i-.?.5/).— Continuing previous work 

 (E. S. R., 12, p. 75), a test on the effect of different fertilizers on pasture land, as 

 shown by gains in weight made by sheep and by the hay crop, is reported. As in 

 previous years, the fertilizers consisted of cotton-seed cake, lime, and ammonia. 

 One plat, No. 6, served for the purpose of comparison and was not fertilized. Some 

 of the results olrtamed in the test in 1900, as well as the results obtained in the four 

 years during which the investigation has been continued, are shown in the following

The hay produced on the different plats in 1900 is reported and the amount com- 

 pared with the crop of previous years. In discussing the tests the author says: 



"Without attempting to draw general conclusions, it may be said that the third 

 and fourth seasons of the Tree Field experiment clearly indicate that manures may 

 modify the value of pasture by affecting the season of growth, as well as by increas- 

 ing the weight of ])roduce. Under the influence of different manures a lati' jiasture 

 may be made earlier, or a short-lived {lasture may be induced to persist far into the 

 autumn. There is nothing new in this assertion; most farmers who have had expe- 

 rience in the manuring of pastures will have remarked it as certainly as they have 

 noted that increa,sed jiroduction of meat follows manuring. But just as tlieTree 

 Field experiment has afff>r(led an exact means of determining the live- weight 

 increase due to the action of manures, so it promises to throw light on the specific 

 effects of certain fertilizers on the (juality, the earliness, and the persistence of pas- 

 tures. Exact information on these points is much wanted, and the future develop- 

 ment of the Tree Field jilats i)ronii.>Je to be instructive."
