Looked at from above, the host appears to be attacked by a leaf- 

 parasite and it is quite surprising to find on the lower surface the 

 sporosphores of one of the Polyporaceae.

RixG-s IN Bark Formed by Branches. — The bark of the 

 white pine, Finns Strobns L., as is well known, usually docs not 

 roughen until the tree becomes quite old, that is ten inches or 

 upward in diameter, although I have seen trees five or six inches 

 in diameter in which part way up the trunk the bark was rough 

 for a distance of four or five feet, the balance both above and 

 below being cntirelj' smooth. 



The branches are vcrticillate and numerous, although in heavy 

 stands of timber the lower whorls usually die back when the 

 shoots are about half an inch in diameter, and even higher up it 

 is usually only three or four that persist and grow to any size. The 

 effect is to give the otherwise smooth trunk a most curious 

 ringed appearance, each ring of roughened bark about about two 

 inches across marking the place of a whorl of branches. These
