 It is estimated that for 8 mill of one hundred thousand feet capacity the cost of conveying the waste from the machine where jt is made and de- stroying if in g closed burner is 42 cents per cord or S10.G5 per day, Burners seldom bring in any revenue. although in a few eases ashes arc sold for fertilizer, and n ? number of others the burner furnisher hot feed water for the boilers.
 Both burners and fire pits add to the insurance rates on lumber. and in the case oI pit on the mill i.sclf. In order to reduce the fire hazard to zero. in the case ot tho burners. it is necessary to keep all lumber piles al least one hundred and fifty feet away from ihe burner. The matter is much worse in the case of pits, especially the open ones, which must he kept three hnud,Cd feet away from the mill and five hundred feet away from any lumber piles. When nearer than tbese distances from the mill and yard respectively, thc insurance rates mount up rapidly with closer proximity until they become practice ally prohibitive when the frepit is nearer than one hundred feet
 No we'll managed mill would pro GHcc waste if it could Do avoided This. however, is not pcs: iblc. so the next best thing is to seek out some method of utilization of the waste so it will pay for it's disposition. The forest service is working on this problem. but has not yet found a satisfactory solution.
