Just what these figures mean can "be seen "by the 

 following calculations: Assume - Species Y.P. 

 Rotation 150 years; stand per acre at end of rotation ~ 

 50 H Bd. ft. Stumpage - 15 per M Bd ft* Planting 

 Interest 5$. 



10 compounded at S% for 150 years equals 640. 



Stumpage will sell at $3L0; leaves (750-640)- $110 for 

 profit and protection* 



Planting at $15 under the same conditions - $15 at Z% for 

 150 years equals about 960; leaves (960-750) or a loss of 

 $210i We must approach. a figure of about 1E to "break 

 oven* 



Discussion* In reply to cue st ion Kotok 

 said "Reforestation "by seeding costs 

 you 5. to 10. per acre; OB a large 

 scale it could "be reduced to 2, to 5. 

 per acre. Results are very uncertain. 

 By leaving seed trees on sales we are 

 probably investing at l&ast $5. per 

 acre in reforestation." 



8:50 - Economy of Using Rangers in Seec. Collection and 

 Field Planting. 



PRATT: 



A, Use of rangers in seed collection not good e- 

 conomy: 



l t Seed collecting season coiaes when multitude of other 

 duties clain rangers 1 time. Necessary worlr in other lines 

 cannot "be done "by temporary labor, Time employed in col- 

 lecting seed is badly needed for supervisory worlr i^iich is 

 always urgent at this time of year on timber sales and 

 grazing. 



2. Cost higher than by contract, as a rule. 



B.Use of rangers in field planting good economy: 

 1* tfor:: of educational and constructive value to rangers. 



2. Spirit of friendly rivairy results in valu&ble ideas.
