State agencies, counties, municipalities, and individual- continued 
active participation in the eradication program during the year. A 
number of counties and cities furnished trucks for transportation of 
laborers and supplies. Farmers cooperated by providing storage 
space and supplying labor, the use of teams, tractors, and other equip- 
ment. Aerial photographs obtained through the cooperation of the 
Soil Conservation Service aided in the more efficient planning of 
survey activities. Experienced Bureau personnel closely supervised 
the work of relief labor crews, with the result that continued improve- 
ment was made in both survey and eradication methods. Field su- 
pervisors used every available opportunity to demonstrate the spread 
of stem rust from barberry bushes to grain, to explain the nature and 
economic importance of the disease and the distinguishing characters 
of the rust-susceptible barberry, and to recommend methods of eradi- 
cation. xV systematic survey was made to determine the prevalence 
and severity of stem rust in the different crop sections of each State 
in the control area, and in Kansas, Oklahoma. Texas, and Mexico. 
Table 8 shows, by States, the progress that was made in eradication 
during the year.
