entire area, but up to the present time chutes and gas trucks have been used. 

 It would seem that a railroad is desirable, particularly in logging the more 

 inaccessible portions of the area. Until more data are accumulated on the size 

 of operation requiring a railroad and as long as the operating company can 

 show a profit by using trucks the Government is not in a position to dictate the 

 method of transportation.

REVISION OF PLAN 



A working plan must be revised at frequent intervals if it is to be workable 

 and not become obsolete. Revision is essential when the original plan is based 

 on rough data. 



This plan should be revised at the termination of the first 10-year cutting 

 period, if revision is not required before that time. 



DATA NECCESSARY FOR REVISION OF PLAN 



1. Division of the area into site classes, based on height of trees. 



2. One hundred per cent estimate of trees over 4 inches d. b. h. left after 

 cutting, and at least 1 per cent estimate of trees under 4 inches d. b. h. 



3. Correction of estimate for both Government and private timber by checking 

 stands cut and left against original estimate. 



4. Yield study by sites on cut-over land to determine the rate of growth after 

 release by cutting. 



APPENDIX, MEADOW VALLEY WORKING CIRCLE 



HISTORY OF WORKING CIRCLE 



Timber exploitation within this circle started in 1913, at which time the 

 Towle Lumber Co. constructed a mill of about 30,000 daily capacity on Slate 

 Creek. This mill was operated by the company from 1913 to the middle of the 

 season in 1915. During this time about 10,000,000 board feet of timber was cut. 



In 1916 the Spanish Peak Lumber Co. was organized, with holdings of over 

 100,000,000 board feet within this unit. A mill of about 65,000 daily capacity 

 was erected at Spanish Ranch. An aerial tramway was constructed to convey 

 the lumber from the mill to the lumberyard at Grays Flat, which is on the 

 main line of the Western Pacific Railroad. 



In 1916 the Government made the present sale of 106,000,000 board feet to this 

 company. Cutting of both Government and private timber has been continuous 

 since that time. 



In 1920 the company purchased the Towle Lumber Company's mill and pri- 

 vate holdings, operating it in conjunction with their own mill during the entire 

 season. 



The cut by years for both Government and private timber from this unit is
