The feeding: of undecorticated cotton cakes to cattle and sheep on pasture,

 7^-75). — The comparative merits of Jv^yptian and J}ond)ay cotton-seed cakes, which 

 are both made from seed which has not been delinted or decorticate<l, werr^ tested 

 with cattle and with wethers, land)s, and ewes for 2 months, the cattle beinjr fed 8 to 

 5 lbs. of cake per head daily during the first month and later 7 lbs. of the cake, and 

 the sheep from 0.25 lb. to 0.5 lb. Considering the test as a whole greater gains were 

 made on tlie Bombay cake than on tlie Egyptian cake. The Boml)ay cake was also 

 considerably cheaper. " So far there is no reason to suppose that the harder and 

 more woolly Bombay cake has had any injurious effects on tlie animals to which it 

 was fed; but this can only be satisfactorily ascertained by a trial covering a consider- 

 ably longer period." 



Analyses of the 2 sorts of cottun-seed cake and of Indian cotton seed by S. H. Collins 

 are reported. The differences observed were not great. " The i)hysical character of 

 the fiber of the 2 c-akes is, however, very different; the til)er of the Bombay cotton 

 cake having an objectionable woolly nature. . . . Indian cotton seed [is] a food 

 greatly esteemed in India for feeding milch buffaloes and cows. Imlian cattle do 

 not api)ear to object to the woolly character of the fiber, and if British i-attle are 

 more fastidious it is i>robal)ly due to the fact that they are accustomed to better 

 feeding." 



Manures for pasture in Tree Field, D. A. Gilchrist {('ountii ('ouncil Norlh- 

 lunhirlaiid, Edacdtioii Com., Jipt. I'JO-i, j>p. 2-18, thjirnt. o). — Tlie effect of manures on 

 pasturage as shown by gains in weight made by sheep was studied under practically 

 the same conditions as in earlier work at Cockle Park (E. .S. R., lo, j). 175). In the 

 20 weeks of the test the average weekly gain per sheep) on all the i)lats was 2.2 11)S. 

 The total gain in weight in excess of gains made by the sheep on the nntreated plat 

 ranged from 27 lbs. made by the 5 sheep on the plat which Jiad T)een manured by 5 

 tons of common lime in 1897 to 144 lbs. made by 10 sheep on the plat which had 

 been manured with 1,680 lbs. of basic slag in 1900. At the close of the test sheep 

 were selected for slavightering from the lots which contained suitably fattened 

 animals. It appeared that sheep fattened best on the plat manured with 660 lbs. of 

 basic slag in 1897 and the sami' amount in 1900. 



The amount of forage remaining on the i:)lats at tlie close of the season was meas- 

 ured by feeding it to cattle during the winter. A botanical analysis of the hay 

 growing on the different jilats is reported. 



The eflfect of nitrog-enous manures on the feeding- value of hay, T. H. 

 MiDDLiCTox [Cuaatii Coinicil yurlltiunhrrl(i)i<l, Educatmn. Com., Bj>t. I'JO.l, pj). oH-iUS). — 

 Since it was found that nitrogenous manures exercise a j>ronounced effect on the 

 character of the hay, feeding experiments with 5 lots of 10 sheep each were under- 

 taken to determine whether its quality was as much affected as its appearance. The 

 hay selected was mixed clover and rye grass grown on unmanured land; early-cut 

 hay from a field top-dressed with 224 lbs. of nitrate of soda per acre; late-cut, but 

 better cured, hay from a field manured as above; rowen, chiefly rye grass, from top- 

 dressed land; and rowen, chiefly clover, from unmanured land. 



The sheep fed rowen hay were given 0.5 lb. i)er head per day in addition to roots 

 and t'oncentrated feed. The others were given 2 ll)s. of hay per head per day with 

 roots, concentrated feed, and a little molasses. In the 105 days of the test the gain
