Extension committee.— This committee has made a final report 

 to the Assistant Secretary, which includes a recommendation that 

 each major bureau of the department detail an employee to give his 

 entire time to extension problems, to be financed by the Extension 

 Service. 



Some preliminary arrangements were made for cooperation with 

 the extension agents of the department in educational work in 

 meteorology, i. e., informing the farmer and the business man what 

 the Weather Bureau has available that would be of assistance to 

 them and how it may be obtained. A trip was made by the official 

 in charge through the Southeast and in some of the States east of 

 the Mississippi River to acquaint the extension agents and others 

 with the nature of our products, and to formulate plans whereby the 

 information could be distributed in the most expeditious and widest 

 manner possible.
