ASH 341 



Of Fungi. The Canker Fungus (Nectria ditissima) 

 causes cankerous spots on the bark, and the timber becomes 

 blackened, and acquires a most unpleasant smell. 



Various species of Polyporus (or Bracket fungi) attack 

 the stems and branches. Fames igniarius causes white rot. 



Of Insects. The Ash Bark Beetle (Hylesinus fraxint] 

 attacks the upper branches of healthy trees, and often kills 

 them. This beetle, together with H. crenatus, is very 

 common on sickly trees. 



The Ash Branch Bark Beetle (H. oleiperda} also occasion- 

 ally does damage. Cockchafer grubs gnaw the roots of 

 young trees. 



Of other Pests. Rabbits are, perhaps, more fond of eating 

 the bark of Ash than of any other tree. 



The American Ash, or White Ash, and the Oregon 

 Ash have probably a great future in this country. Though, 

 until their success be proved by time, any planting of them 

 must be regarded somewhat in the light of an experiment. 

 There is, however, every probability that the Oregon Ash will 

 prove a most valuable tree in this country ; and may, possibly, 

 rival the Common Ash. 



Both grow very quickly, and they are peculiar in that 

 their seed germinates during the first year. They are usually 

 rather later in coming into leaf than the Common Ash, and 

 so often escape a spring frost when the common variety 

 suffers. 



The White Ash will grow on rather dry, sandy soils, 

 such soils being far too dry for the Common Ash. It is 

 therefore worth an extensive trial on such soils. It is the 

 quickest growing of any variety of Ash. 



The Green Ash is not likely to be of much value, as it does 

 not usually grow to a large size.
