116 WILSON EXPEDITION TO CHINA 



This species, which is one of the most valuable of the Chinese timber trees, is 

 everywhere common up to 1000 m. altitude. It is a medium-sized tree with a 

 relatively slender trunk and gray, roughish bark which exfoliates in thin, irregularly 

 oblong sheets. The branches are small and ascending and form a narrow head. 

 The wood is white or nearly so, heavy and very tough. It is largely used in turn- 

 ing and for making pulley-blocks, tool handles and for any and every purpose 

 where strength is needed. Colloquially this tree is known as the " Tian shu," 

 and the wood as " Tian mu." Pictures of this tree will be found under Nos. 63, 

 473, 626, 719, 0247 of the collection of my photographs and also in my Vegetation 

 of Western China, Nos. 198-200. E. H. W.
