EXPERIMENT STATION BULLETINS. 355 



the majority of cases the deficiency in protein was accompanied by an 

 excess in fiber or hulls. 



This condition, as explained by the manufacturers, is due to an un- 

 usual demand on the part of the munition manufacturers for lint or 

 short fiber cotton. To meet this demand the seed has been cleaned more 

 llioroughly than ever before which has made it more difficult to maintain 

 llie quality of the meal to that of the present standards. \Miile such a 

 condition may, perhaps, be unavoidable under the existing conditions, 

 there is, certainly, no good reason why the manufacturers and shippers 

 sljould not have frankly made the facts known to the buyers and lowered 

 their guarantees to conform to the actual analysis of the meal. 



An examination of the tables of analyses will show which companies 

 were most derelict in fulfilling their obligations to the buyers. 



LINSEED MEAL. 



Forty-six samples of linseed meal representing 13 manufacturers or 

 shippers were received, only two of which were found to be low guaran- 

 tee in protein. Some of the samples contained an excessive amount of 

 screenings and other foreign materials. 



FLAXSEED MEAL, 



Four samples of flaxseed meal were collected and analyzed. None of 

 the samples carried a guaranteed analysis as pure flaxseed meal is ex- 

 empt from the provisions of the law. 



Two of the samples contained excessive amounts of screenings and 

 other foreign materials and on presenting the fact to the manufacturers 

 they have given assurance that their products will be kept reasonably 

 clean in the future. 



DISILLERS' DRIED GRAINS, CHIEFLY FROM CORN. 



Seventeen samples of corn distillers' grains were collected. The 

 samples of "Continental Gluten Feed" manufactured by the Continental 

 Cereal Co.,. Peoria, Illionis, included under this classification, were all 

 below guarantee in both protein and fat. It is significant to note that 

 the average percentages of protein and fat in the five samples were 4.4 

 per cent and 3.5 per cent respectively below the average for all the other 

 samples of this class while the average price was only 50 cents per ton 

 lower. 



CHIEFLY FROM RYE. 



Two samples of rye distillers' grains were collected both of which 

 were below guarantee in both protein and fat. Several unofficial samples 

 of this brand were also received from purchasers, the majority of which 

 were found to be below guarantee in protein. The Interstate Feed Asso- 

 ciation was notified of our findings and also requested to change the 

 guaranteed analysis since which time has been selling under a guarantee 

 of 15 per cent protein.
