528 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 



a number of States and are now in use in all of the important grain- 

 sorghum markets. Further study has been given to the tentative 

 grades for rye, which were established during the previous year, and 

 some minor changes have been made. These grades are now being 

 published. Investigations were carried on also covering rough rice, 

 brown rice, flax, and barley looking toward the establishment of 

 United States grades for these grains. 



Investigation of the milling and baking qualities of wheat varieties 

 was conducted for the purpose of securing information which will 

 lead to the development and production of superior wheat. Milling 

 and baking investigations of the various classes and grades of wheat 

 marketed in commerce and special investigation covering the factors 

 determining commercial grades were carried on in connection with 

 suggested changes in tlie Federal wheat grades established by the 

 department under the grain standards act. 



Seed of an Asiatic grass (Adlay) grown in the Philippine Islands 

 was experimented with from the standpoint of its bread-making 

 qualities. Methods and equipment for milling this seed, as well as 

 the milling and baking results from tests of various mixtures of flour 

 from Adlay seed and wheat flour, were reported. 



Two types of an improved grain-cleaning device designed for use 

 on threshing outfits were developed and tested experimentally in the 

 Pacific northwest and central northwest grain-producing areas last 

 harvest. Both types gave very satisfactory results. The recleaners 

 with improvements developed during the last harvest are being oper- 

 ated experimentally during this harvest in both the Pacific and 

 central northwest. General use of the improved recleaners on thresh- 

 ing outfits will greatly benefit the producer and country shipper. It 

 will enable the producer to put upon the market a higher grade and 

 more valuable product and at the same time the country shipper will 

 be saved transportation charges on trash. 



Investigations of the bulk handling of grain in the Pacific coast 

 producing section and at export points has been conducted in con- 

 nection with the transition from sack to bulk handling of grain in 

 that territory. As a result of these investigations it has been pos- 

 sible to assist producers and country dealers interested in handling 

 grain by bulk, also State agencies and municipal authorities in- 

 terested in port facilities for grain handling. 



A number of bulletins were published (see list at end of this report) 

 and manuscripts for other bulletins, covering United States grades 

 for rye and grain sorghums, bulk handling of grain on farms, foreign 

 material in spring wheat, and a revised handbook covering' the of- 

 ficial grain standards for wheat, shelled corn, and oats were prepared 

 during the year and submitted to the printer.
