As there is a gradual accumulation of litter within 

 the forest after each burning, the owner can never be 

 certain that the inflammable material is of such limited 

 extBBt that a damaging fire cannot occur, unless he 

 burns each season. It is obvious that Light Burning 

 costs as compared with those of prevention and suppress- 

 ion of fires, renders the former method impracticable.

The damage occurring to grazing, to watersheds 

 and the soil, are also of vital Importance. This is 

 particularly true in California, where grazing is pre- 

 valent and irrigation is employed extensively.
