YOUNG TREES AND SUNSTROKE 149 



liable to be scorched than during a period of 

 prolonged sunshine. 



When trees are planted out singly it is well to 

 choose those with spreading heads and low stems, 

 as then the tree will shade itself to a great extent, 

 the short amount of bare stem being less exposed to 

 the sun's rays than a taller one. After all, this is 

 only Nature's method of protection, as, in a wild 

 state, no young tree is bare-stemmed, except in a 

 wood, where it is shaded by those near it. On the 

 edge of a wood, or in the open, young trees are 

 furnished to the ground with foliage, which is not 

 shed until the stem has become hardened enough to 

 withstand climatic vicissitudes. If trees with tall 

 stems are the only ones available, then the stems 

 should be shaded by some means for a year or two, 

 especially when they have become established and 

 are making strong, sappy growths, as the stem is 

 practically in the same condition and apt to be 

 scorched by a sudden burst of hot sunshine. 



Goat and Wood-Leopard Moths 



Sunstroke must not be confounded with the 

 ravages of the caterpillars of the Goat Moth and 

 Wood-Leopard Moth, the external signs of which 

 are much the same, but on the bark being removed 

 one or two channels almost the size of a man's 

 little finger are to be seen, together with accumula- 

 tions of wet sawdust-like material deposited by the 

 caterpillar. These are exterminated by thrusting a
