Analyses arc also reported of table salt, gypsum, volcanic ash, and magnesite. as 

 well as a mineral analysis of onion chaff. The latter contained 4.89 per cent water. 

 7.89 per cent ash, 1.54 per cent nitrogen, 0.7l' per cent phosphoric arid, 0.14 per 

 cent potash (actual), and 4.34 per cent ether extract. In the author's opinion onion 

 chaff would have more value as stall litter than as a fertilizer. 



Licensed commercial feeding stuffs, 1904, F. W. Woll and G. A. Olson ( Wis- 

 consin Sta. /»'"/. lis, pjt. :,o). — Data are given regarding the guaranteed composition of 

 the 52 brands of feeding stuffs licensed for sale in Wisconsin for the year ending 

 December 31, 19:i4, as well as the results of analyses of a number of samples of 

 licensed feeding stuffs, unlicensed feeding stuffs, feeds not subject to license, and 

 miscellaneous feeds. A number of samples of unlicensed feeding stuffs not offered 

 for sale in the State were also analyzed. The feeding stuffs analyzed included ground 

 linseed cake, oil meal, viscid oil meal, cotton-seed meal, gluten meals and feeds, 

 hominy feed, mixed corn and oat feeds, miscellaneous dairy feeds, animal meal and 

 similar goods, poultry feeds, rape meal, distillers' grains, mixed and proprietary 

 feeds, granulated bone, meat meal and similar products, wheat bran, middlings, red 

 dog flour, cereal oil meal, corn distillers' grains, mustard-seed cake, rape-seed cake, 

 corn, corn meal, oats ( whole and ground) , barley, ground spelt, dried brewers' grains, 

 ground malt, malt sprouts, mixed feed, cereal middlings, buckwheat bran, and mil- 

 ler's smut. The text of the State feeding-stuff law is quoted. 



In the case of the guaranteed feeds a large number were not up to the standard in 

 composition, but the authors believe that the deficiencies were, as a rule, perhaps 

 unintentional and ■'came from a lack of close supervision of the chemical composi- 

 tion of the output of the lactone-, rather than from any intention to deceive the 

 consumers. In other cases, as for instance in the brands of the oil meals, a defi- 

 ciency in protein was always accompanied by an excess of fat above the guaranty. 

 In this case the buyer was not necessarily the loser, since the feeding value of fat 

 for some purposes is at least equal to that of protein, but feeds of this class are, as a 

 general rule, purchased for the sake of supplanting farm-grown crops or more starchy 

 mill-feeds with protein, and tin- buyer has, at any rate, a right to obtain the feed 

 which the jniaranty of the dealer of the feed would suggest, and not one equally 

 good." 



Concentrated feeding stuffs licensed for sale in Wisconsin, 1905, F. W. Woll 

 ( Wisconsin Sta. Bui. 120, />/>. 8-5, 7-9). — A list is given of the feeding stuffs which 

 are licensed for -ale in the State in 1905, together with their guaranteed protein and 

 fat content, and the text of the State feeding-stuff law is quoted. 



Cacti as forage, R. II. Forbes and W. W. Skinnei; {Arizona Sta. Jij>t. 1904, pp. 

 496, 497). — Owing to the local interest in various sorts of cacti as cattle feeds, the 

 chemical composition of a number of such plants was studied. In quoting the results 

 the analytical data have been recalculated on the basis of fresh material.
