SHADE TREES.

 of a fine old elm. 



GINKGO. 



A tree (Ginfcgo biloba, L.) introduced thirty or forty years 

 ago from Eastern Asia. It grows rapidly on almost any 

 soil, develops a narrow cylindrical or conical crown that 

 adapts it well to narrow streets, and is apparently not af- 

 fected by insects or disease. The fan-shaped leaves with 

 straight veins are unlike those of any native tree and their 

 bright coloring in the fall sometimes rivals that of the 

 maples. The only objection thus far made to the ginkgo 

 as a street tree is that its fruit, an oily nut, is sometimes 

 malodorous. Even where the heat reflected from paved 

 streets is considerable the tree thrives. It promises to be 

 one of our most valuable species.
