ASH.

Ash is extremely durable if felled in the winter 
months and proper-ly seasoned before use ; but where 
these precautions are neglected few woods are more 
perishable. Very great advantage will be found in re¬ 
ducing the Ash logs soon after they are felled into plank 
or board for seasoning, since, if left for only a short time 
in the round state, deep shakes open from the surface, 
which involve a very heavy loss when brought on later 
for conversion. 
Ash wood, when beginning to decay, changes at 
the centre to a blackish colour, as also it will do if 
the trees are pollarded or topped off during growth, 
hence the “best quality” should be uniformly greyish- 
white throughout 
There are several varieties of the Ash which attain 
timber size, and those which are raised for ornamental 
purposes in this country are very numerous. This tree is 
remarkable for its lateness in putting out its leaves in the 
spring, and for throwing them off very early in the 
autumn.
