diam. 67 ft. S.G. 389. W 24-25. K 770 kilos. The quickest 

 growing of Poplars. Sapwood very wide, nearly white, heart 

 brownish, not durable if exposed to moisture, but of larger 

 dimensions than, and equal in quality to any other Poplar. 

 Used for flooring, clapboards, inferior fuel, and extensively for 

 paper-pulp, for which purpose it is now largely and remunera- 

 tively planted in Britain. "Were every cottager to grow his 

 own fuel . . . perhaps no tree would succeed so well " (London). 

 The polishing wheels used by glass-grinders are made of hori- 

 zontal sections across the entire tree.
