When brush disposal was initiated, operators throughout this district were very much opposed to it, but now take it as a matter of course, and we have very few complaints from this source. One of our largest operators in the lodgepole type in Wyoming has complained on several occasions of the added responsibility thrown on the operator's shoulders from this source, and has asked that the Service take entire charge of brush disposal, carrying it out at such times as may seem best and meeting the costs from funds deposited by the operator for this purpose from time to time. This is an unusual case, however, and, where the burning is properly supervised by the operator, little trouble occurs. Shortly after piling and burning was initiated we had some trouble with operators because of their lax supervision of this phase of the operations, and, because of a general inclination on their part to consider brush disposal impracticable, they make no effort to carry it out properly. When an honest effort is made to secure efficiency in its disposal, operators secure results at very low cost and rarely, if ever, complain of this feature, particularly in view of the fact that our stumpage appraisals now consider brush disposal as a distinct item of operating costs and allow a rather liberal figure for it.
The only compensating advantages I can think of which ensue to the operator through brush disposal, are the slight reduction in the fire hazard and, as previously mentioned, the slightly increased freedom in skidding operations. If a sufficient margin has been allowed for brush disposal in the stumpage appraisal, I think these two points can really be considered as distinctly advantageous to the operator. How-
