FOEEST TREES AND FOEEST SCENERY 



the excessive or ill-timed grazing of 

 sheep, which trample to death the 

 young tree seedlings as they pass over 

 the ground in great herds and devour 

 the last vestiges of vegetation, thus 

 leaving a bare and dry forest floor, 

 upon which the old trees subsist 

 with difficulty through the prolonged 

 droughts of summer.
