6(i EXPERIMENT STATION RECORD. 



to growth niul ease of propaj^ration render them of less vahie than the prickly 

 I)ear, except in certain limited localities where they are especially abundant." 



The bulletin contains a brief summary of literature regarding the feeding 

 value of cacti and a general discu'ssion of the importance of these plants as 

 feeding stuffs in arid regions. 



Concentrated feeding stuffs, .J. I'. Street, ,J. W. Kellogg, and V. J. Cae- 

 UERRY (\cir ■Icrxcii Stas. Bui. llil. iip. ',<;). — ITnder the State feeding-stuff law 

 471 samples were analyzed, of which 804 belonged to the class that required a 

 guarantee. 



The goods analyzed included cotton-seed meal, linseed meal, gluten meal 

 and feed, corn bran and similar goods, hominy meal and feed, distillers' grains, 

 malt sprouts, dried brewers' grains, molasses feeds, proprietary mixed feeds, 

 alfalfa meal, barley feed, curled cocoanut fiber, dried beet pulp, beef biscuit, 

 proprietary poultry feeds, meat meal, beef scraps and similar goods, wheat bran, 

 feeding flour, wheat middlings, wheat feed, ground wheat, wheat and rye 

 bran, rye bran, rye feed, rye middlings, ground rye, corn meal, corn and cob 

 meal, ground oats, ground corn and oats, ground mixed grains, buckwheat mid- 

 dlings, buckwheat bran, and buckwheat feed. 



"Of the IGO different brands of feed received, and whicli should have been 

 guaranteed, 2 failed to meet this requirement. 



" Of the 304 samples whicli were guaranteed, 77 were deficient, 53 of these 

 being low in protein. 



" Of the 107 samples which did not require a guarantee, all were pure prod- 

 ucts, but the wheat brans and feeding flours were.below normal quality : one 

 sample each of wheat middlings, rye middlings and rye bran were misbranded. 



" No direct adulteration is reported, but the inferiority of cotton-seed meal 

 this year, and the poor quality of certain molasses grains and alfalfa meals, 

 are worthy of notice. 



"Certain feeds of good <)nality still liear guarantees higher tlian their com- 

 ]iosition warrants. 



"The variability in composition of certain high-grade feeds and the absence 

 of a corresponding variation in selling price demands that a strict regard must 

 be given to the prices asked, as well as to the amount of nutrients guaranteed. 



"The cheai)est protein feeds this year were buckwheat middlings, mali: 

 sprouts, dried lu'ewers' grains, high-grade distillers' grains, and cotton-seed 

 meal." 



Analyses of feeding stuffs and mineral and spring waters, A. L. Knisely 

 (Orcyoii fSta. Rpt. lUO.j, in>. 60-l.i). — Analj-ses are reported of western wild 

 oats {Avena fatua) at different stages of growth, alfalfa, blue clover (Mclilottis 

 cocrulea), mill feed, oat chop, dairy chop, gluten feed, wheat bran, prepared 

 cattle food, and several varieties of barley. A number of mineral and spring 

 waters were also analyzed. The percentage composition of wild oats in 

 proper condition for hay making was water (51.11, protein ^.72, fat (ether 

 extract) 1.58, nitrogen-free extract 22.G1, crude fiber 0.20, and ash 2.78 per cent. 

 The percentage composition of blue clover was water 11.03, protein 19.17. fat 

 2.07, nitrogen-free extract 3G.71, crude fiber 22.44, and ash 7.98 per cent. 



Judged by the analytical data. " wild oats are considerably richer than aver- 

 age timothy hay, nearly as rich as Kentucky blue grass or redtop, and compar.^' 

 favorably with orchard grass and ordinary oat hay. . . . The so-called blue 

 clover is a plant exceedingly rich in protein." 



Grape marc and its utilization for feeding farm animals, E. Bertain- 

 CHANi) (Bill. Dir. Afjr. ct Com. [Tunis], 10 (IDOG), No. .'/, pp. 527-.T2.')).— Analy- 

 ses are reported of different sorts of grape marc and its value as a feeding 

 stuff is favorably spoken of.
