THE AUTHORS 



CHARLES W. PHILPOT is a Research Forester in the Fire Physics 

 research work unit at Missoula, Montana. His B. S. and M. S. 

 degrees in Forestry were obtained in 1961 and 1962, respectively, 

 from the University of California at Berkeley. He received his 

 Ph.D. in Plant Science-Forestry in 1970 from the University of 

 Montana. He was assigned to the Pacific Southwest Forest and 

 Range Experiment Station at Berkeley from 1961 to 1963 and to the 

 Riverside Forest Fire Laboratory in Riverside, California, from 

 1963 to 1966. In 1966 he transferred to Lntermountain Station's 

 Northern Forest Fire Laboratory at Missoula, where he initiated 

 the first fuel chemistry studies. He has shown the chemical com- 

 position of plant materials, pyro lytic reactions, and the behavior 

 of the extractives to be important in fire spread, intensity, and 

 fuel ecology. 



ROBERT W. MUTCH received his B. S. degree in Biology from Al- 

 bion College, Michigan, in 1956 and his M. S. degree in Forestry 

 from the University of Montana in 1959. He was Superintendent 

 of the Priest River Experimental Forest in northern Idaho from 

 1958 to 1960. Since 1960, he has been engaged in wildland fuels 

 research at the Northern Forest Fire Laboratory, and is cur- 

 rently participating in a wilderness fire study with personnel from 

 the Northern Region of the USDA Forest Service.
