trivance in actual use shall be left during the noon hour without a 

 watchman, and during the same period of each year the purchaser may 

 be required at the discretion of the Forest officer to employ a night 

 watchman to guard against the escape of fire from the logging engines, 

 (w. y. p., w. f., s. p., C. Tahoe, D 5, 1912). 



The most satisfactory fire protection measure (a) is to use 

 oil for fuel ; any wood or coal-burning steam engine is dangerous. 

 Even oil if forced unproperly in feeding by a green fireman may, 

 with some machines, set fires. There is always some damage 

 from rigging (b) ; consequently if steam logging can be avoided 

 it is preferable from the lessee's standpoint to (c) (c'=recent 

 revision) prohibit the use of donkey engines or steam skidders 

 (d) (e) (f) (h) (i) (j) are clear. The officers in D 6 

 have, it is understood, hit upon a satisfactory spark arrester al- 

 though it must be admitted that without repeated and careful 

 inspection, spark arresters are dangerous (g). 



PROGRESS OF CUTTING. 



2y. (a) No timber will be cut, except from the areas specified by the 

 Forest officer. Cutting and other phases of the operation will only be 

 allowed, and shall be completed successively, on such portions of the 

 sale area as may be designated by the Forest officer. No Hve timber 

 will be cut except that marked or otherwise designated by the Forest 

 officer. If for any reason the Forest officer orders the cutting to cease 

 on the whole or any portion of the sale area, no further cutting will be 

 done until the Forest officer gives him permission. 



(b) Cutting shall progress in such a manner as in the opinion of the 

 Forest officer in charge, will not cause depreciation of the stumpage 

 value of the uncut timber remaining on the sale area. (1. p., E. s., b. 

 f., Medicine Bow, D 2, 1911). See also 25. 



ANNUAL AMOUNT TO BE CUT AND REMOVED. 



28. (a) Second, unless extension of time is granted, all the timber 

 except the 15,000,000 feet of white pine timber will be paid for, cut and 

 removed on or before January ist, 1914, and 20,000,000 feet of the white 

 pine timber will be paid for, cut and removed on or before January ist, 

 1915, and the remaining merchantable portion of the timber on the 

 area first described in this instrument will be paid for, cut and removed 

 on or before and not later than January ist, 1916, provided that if the 

 actual scale of the timber overruns the estimate of the entire area 

 by 15 per cent, the Company at its option upon application to the Dis- 

 trict Foresters, will be granted an extension of time to cut and remove 

 the remainder of the timber uncut on January ist, 1916, from the area 

 first described in this instrument, or be relieved from the obligation to 

 cut and remove any timber in excess of the fifteen per cent, overrun of 

 the estimated amount of 75,000,0000 ft. B. M. on the area herein first de- 

 scribed (w. w. p., Coeur d'Alene, D i, 1911-) 



(b) A period of twenty (20) years will be allowed for the cutting
