prohibitive to adulterated goods. It is gratifying to note that 

 in no case has the percentage of protein fallen materially below 

 the guarantee. From the fact that much of the cottonseed meal 

 carries more protein than the guarantee, it will probably result 

 in grading the cottonseed meals according to their composition. 

 One firm in the winter of 1898 handling unusually good cotton- 

 seed did this, guaranteeing the meal to carry 49 per cent protein, 

 instead of the 43 per cent of the other brands. 



Linseed Meal. 



Linseed meal is made by grinding flaxseed from which the 

 oil has been more or less completely extracted. "Old Process" 

 contains more fat and somewhat less protein than"Xew Process" 

 linseed meal. 



True and Company based their guarantee upon an analysis 

 made for them by the Station in October, 1897. Of the two 

 samples collected, one was a little above, the other a little below, 

 the guarantee. The goods were quite uniform, however. 



The Cleveland Linseed Oil Company placed the same guar- 

 antee upon their oil meal as on their flax meal. The flax meal 

 proved better and the oil meal poorer than the guarantee. The 

 attention of the company has been called to this, and they will 

 doubtless change their guarantee of protein in the oil meal. 



Only three samples of linseed meal were found by the inspec- 

 tors in November. Its high cost, relative to cottonseed meal 

 had apparently crowded it out of the market. The guarantee of 

 Douglass & Company's oil meal was based upon an analysis of 

 a sample sent to the Station months before by the wholesaler, 

 who writes as follows : "When you analyzed our oil meal we 

 had a large quantity on hand, and we tagged as you directed. 

 It is so high now that very little is sold and we have had a few 

 lots that we have sold and we supposed was of same quality. 

 We have not at present a single sack in our store." 



Gluten Meals and Feeds. 

 Gluten meals and gluten feeds are by-products left in the 

 manufacture of starch and glucose from Indian corn. Corn 

 consists largely of starch. The waste product from the manu- 

 facture of starch or susfar is relativelv much richer in oil and
