TIMBEK GROWING AND LOGGING PRACTICE IN CALIFORNIA 61 
and generalized rules for desirable practice, based on research and 
experience, and to specify in detail only those practices which prop- 
erly can be so stated. 
The principal factors are fire protection and slash disposal, 
logging methods, and intensity of cutting. Each of these will be 
treated separately. 
SLASH DISPOSAL AND FIRE PROTECTION 
The essential slash-disposal and fire-protection measures required 
to keep forest lands productive have been discussed in the first section 
of this bulletin. An adequate general protection system, care with 
fire, and special protection measures and patrol are, of course, equally 
needed on lands managed for full timber crops. 
Fig, 22.— slash PROPERLY PILED READY FOR BURNING 
When slash is well piled, damage to young growth and seed trees is largely 
avoided. Compact piles located away from the remaining trees and young 
growth accomplish this. 
Partial disposal of logging slash plus patrol, with the object of 
minimizing fire danger, was recommended for owners who had not 
fully decided on deliberate growing of timber, and whose primary 
interest was to keep the lands valuable for sale or exchange. To such 
owners the immediate cost of piling and burning, mentioned as a 
desirable and effective means of reducing hazard, is likely to be a 
deterrent, because it is not certain that this cash investment can 
always be recovered in sale or exchange. But once a land policy of 
timber growing is decided on, additional measures for protecting the 
investment can and should be adopted. Under these circum- 
stances, pending further study of the partial disposal plan, piling 
iand burning of the slash is recommended as a superior method.
