The cross section area per cent., based on the area in 1907 in 

 the two experimental areas as a whole, was found as follows : 



showing a most decided influence of the dry and rainy seasons. 

 Differentiating now the two parts in the two areas, the one 

 with the moss cover turned (a), the other with the living moss 

 cover (b), the following difference in the cross section area per 

 cent, appeared; the basis being again the total area in 1907: 



I 



II 



1908 1909 1910 



a .343 2.018 1.778 



b .086 2.067 I. 611 



a .105 1.346 1.365 



b .072 1.436 1.465 



The stands with the living moss cover remain in the drouth year 

 behind those with the dead cover, the younger stand more than 

 the older. In the two wet years the opposite relation appears, the 

 fully saturated living moss bolsters acting favorably in hot days 

 of the wet season. 



This showing accentuates the desirability of destroying the 

 living moss cover. A removal or breaking up every five years, 

 which in those parts may be done by the poor farm population 

 gathering the litter for bedding, is the proposed method.

Setting out young trees of those species 



Planting which develop a pronounced taproot is 



with always attended by liability of injury to 



Borer. this root and consequent set back in the 



growth of the plant. A conical, auger-like 



borer with a blade 7^ inches long and 5 inches across at the top 



has proven very satisfactory for this work and very cheap in use.
