18 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



Much progress was made during the year in the wool standardiza- 

 tion work. More than 500 sets of the tentative wool grades have 

 been prepared and distributed among wool manufacturers, dealers, 

 growers, agricultural colleges, and others interested, evei'y State 

 being represented. In this way interested people are able to study 

 the grades until they come to know them. 



Up to the present time grades have been formulated and rec- 

 ommended for 14 of the more important fruits and vegetables. 

 These grades have been brought to the attention of growers and 

 dealers through demonstration work done in cooperation with State 

 representatives and with organizations of growers. Assistance also 

 is given to States in preparing and revising grades for a large num- 

 ber of products. 



Tentative standards have been prepared for eggs, and attention 

 is being given to the preparation of standards for live and dressed 

 poultry. 



Tentative hay grades have been formulated for timothy, clover, 

 timothy and clover- mixed, mixed grass and timothy, and grass mixed 

 hay. A complete exhibit of these grades has been prepared for 

 display at conferences, conventions, terminal markets, and elsewhere. 

 Also a bulletin on the subject "Laboratory Methods in Hay Stand- 

 ardization " is being prepared for early publication. 



REVISION OF GRAIN STANDARDS. 



Complaint of the wheat grades, especially in the Northwest, led 

 to a very thorough study of these grades during the summer and 

 fall of 1921. Experts not connected with the department were 

 employed to make a full investigation in the field. Many confer- 

 ences were held with the trade and inspection departments, as well 

 as with producers. As a result of these investigations some slight 

 changes were made in the wheat and corn grades, and important 

 changes were made in the rules governing inspection performed by 

 licensed inspectors. In the hope of being of further assistance to 

 the wheat interests in the Northwest, a price-reporting system de- 

 signed to furnish producers and dealers with comprehensive infor- 

 mation regarding market conditions and prices at the terminals 

 was inaugurated. In addition to this, an extensive " Know-your- 

 own- wheat " campaign is being conducted in cooperation with the 

 extension directors and other agencies in the States of Minnesota,
