ance to the ordinary run of gum-trees that the occurrence of turpentines is often a 
relief to the eye. My experience tends to show that turpentines have a large number 
of roots near the surface, which, if disturbed, readily kill the tree. I would not, 
however, like to generalise on this point. I have seen some experiments on 
pollarding the turpentine. The trees were cut in the month of May, and have freely 
sent forth leaf-buds a considerable distance down the trunk, giving the tree quite 
an ornamental appearance. Where a tree is growing too large, and it is not necessary 
to absolutely remove it, the experiment I have indicated might he made.
