 the products of rice at the (liferent stages of the milling process were 

 obtained from one of the principal milling establishments of New 

 Orleans and analyzed at the Station. The samples included " rough 

 rice'' (as shipped from the plantation), "rice from the stones," 

 " pounded rice." bran. " rice from the cooling floor," " polish." cleaned 

 milled rice, and hulls. Rice straw, obtained from another sou.rce, was

 The digestibility of the albuminoids was estimated by treatment with 

 pepsin solution. The absolute and relative cjuantities of the jjroxi-

BULLETIN No. 25 (STATE STATION). 



Analyses of commercial fertiuzeks and other substances use- 

 ful TO AGRICULTURE, W. C. Stubbs, Pii. D. (pp. 301^17). — Tliis 

 includes reports on the analyses of forty-seven diiferent kinds of com- 

 mercial fertilizers, besides limestone, marl. " gluten meal," guano, 

 water from an artesian well, and bituminous coal. The sami)les were 

 selected by the Connnissioner of Agriculture, or by the ])urchaser, 

 under regulations prescribed by the Commissioner or by the Station; 

 or were sent to the Station by private parties. The full text of the 

 fertilizer law and popular explanations of the ingredients and valua- 

 tions of commercial fertilizers are given, together with descriptions 

 of the samples analyzed and tabular records of the analyses. " The 

 demand for fertilizers during the last season has decidedly increased. 

 The general character of the ai'ticle oH'cred for sale has been fairly 

 within the guarantee given." 



XJntU'i- the fertilizer law every citizen of the State is amply protected from 

 fraud and imposition by iinscrnpulons dealers, and there exists absolutely no 

 cause for distrust in the piirchase of conunercial fertilizers, if the farmer will 

 but claim the protection afforded him. The sellers of good wares are also pro- 

 tected, as ample facilities are afforded them of properly advertising their goods. 



It is also stated that cotton-seed meal is largely used as a fertilizer 

 in all ])arts of Louisiana, being considered the cheapest and best 

 source of nitrogen, and that the use of tankage is increasing.
