As a further precaution against the spread of fires, our 

 field force requires public highways, railroads and trails to be 

 kept clear of brush and inflammable debris. Logging opera- 

 tions are closely followed, and the slash therefrom must be 

 taken care of in such a way as to remove as far as possible 

 the danger from fire. It is not always possible to burn the 

 brush following logging operations, nor is it in many cases de- 

 sirable. The method of disposal used depends entirely on the 

 local conditions, such as the character of the timber, the den- 

 sity of the stand, and the kind of soil. Wherever logging oper- 

 ations are carried on in mixed stands, and that valuable 

 hardwood timber is left standing, it is manifestly undesirable 

 to start a fire that will sweep over the ground completely. 

 The timber remaining will be either killed directly by the fire, 

 or eventually overthrown by wind, on account of the burning 

 up or drying out of the ground cover. Under favorable condi- 

 tions, on all pure stands of pine, the brush is burned as the 

 work proceeds. 



During the past season the Service has erected over ninety 

 lookout towers for the use of the patrolmen and rangers. With 

 the aid of these the field men are able to watch a much larger
