lone a section will carry one band of Bheep and immediately 

 receive the reply that it took so many days to food it. 



When we know by aotunl grazlnrj how long a section 

 will carry a given amount of etook TTO heve accurate dnto 

 fjr caparison with unfod ranges to 50 1 their carrying 

 capacity. 



Then ooroparing tho value of ono typo \vlth another 

 we have definite <?oto to estimate the carrying capacity of 

 any ran^ro in thet vicinity. V/o fully realize that tho typoc 

 uoed in thin system and their forage value might not n^ply 

 to other Forests, but think that the theory of estimating by 

 fee' types and by tho number of days feed per unit 10 aound 

 and can be applied under any conditions.

 have noticed fifty youn^ trees, averaging thirty feet hl^h 

 and 10 inches D.3.H., that have boon killed or ruined along 

 the Lemon Canyon road this Spring. I have also noticed that 

 tho dcnage is usurlly done to trees fjroTvin,^ In openings, where 

 no dou>jt tho br.rk, owlnr 1 : to the extrr. amount of sunshine, is
