equal quantities were fed in separate boxes at the same time to each 

 horse of the 3 teams. In^order to exclude a possible error due to the 

 convenience in the positions of the feed boxes, which were placed 

 side by side, the bleached and unbleached oats were fed in different 

 boxes on alternate days. It was observed that each horse ate the 

 bleached oats as readily as the unbleached oats. Frequently the 

 horses ate from the boxes alternately, so that they finished eating 

 both the bleached and the unbleached oats at practically the same 

 time. 



Profits Resulting from Bleaching. There are two sources 

 through which a profit is derived by 1;he process of bleaching oats. 

 (1) By purchasing low grades of oats, improving their appearance, 

 and selling them at approximately the price of unbleached oats of 

 similar appearance, and (2) by increasing the original weight by 

 the addition of moisture during the bleaching process. 



The cost of bleaching grain with sulphur depends largely upon 

 the facilities available for handling and the quantity of grain 

 bleached. The average capacity of a bleacher is about 3,000 bushels 

 per hour. The cost of the sulphur (20 to 30 pounds) required to 

 oleach 1,000 bushels of grain should not exceed 50 cents. The 

 steam required for the process is not an expensive item, as it is 

 usually at hand for running other elevator machinery. From esti- 

 mates obtained from various persons engaged in this line of work 

 the cost of bleaching, when the plants are running full capacity, 

 varies from about one-eighth to one-quarter of 1 cent per bushel.
