RE^MBION OF PLAN 



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

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

 on rough data. 



This i)lan should be revised at the termination of tlie lirst 10-year cutting 

 period, if revision is not required before that time.

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. 



.'i. Correction of estimate for both GoA-ernnient and private timber by checking 

 stands cut and left against original estimate. 



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

Timber exploitation within this circle startetl in 1J)13, at which time the 

 Towle Lunil)er Co. constructed a mill of about :iO.0()O daily caiiacity on Slate 

 Creek. This mill wms oiperaUvl by tlie company from IJU.'S to the miildle of the 

 season in lOlii. During I his time about 10,U00.0(K) board feet of timber was cut. 



In 1!)1(> the Spanish Peak Lumber Co. was organized, with holdings of over 

 100,(KJ0,000 board feet within this unit. A mill o{ about G.O.OlK) daily capacity 

 was en-cteii at Spanish lianch. 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 l'aci(i<- Railroad. 



In 1910 the Government made the present .sale of 100,000,000 board feet to this 

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

 since that time. 



In 1!»2<) the company purchased the Towle Lumber Company's mill and pri- 

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

 season.
