'"TWIST" IN TREES. 

 By Wm. Ham. 



Nature-observers in Australia have doubtless often noticed 

 the number of native trees which have a decided twist in their 

 trunks, giving the appearance of having been bodily turned 

 round. In many cases, though probably not in all, this twist is 

 carried right throug'h the wood of the tree. I do not know of 

 any scientific observations on this subject.
