weather conditions during the summer much 

 better than they could previously. One example 

 of such use is evidenced in table 12, which was 

 devised by fire control officers in Interior Alaska 

 to indicate progressively worsening burning con- 



ditions according to cumulative moisture content 

 and current burning index. Such a table facili- 

 tates wiser use of equipment and manpower in 

 organizing both fire preparation and fire sup- 

 pression activities.
