60-80 ft. in height, are known. The best results may be looked 

 for by planting it in deep moist loam, where the atmospheric 

 conditions are moist and free from impurities. It succeeds, 

 however, under much less favourable conditions, even when 

 planted in the centre of an industrial town. An old tree grow- 

 ing in a small yard between the Gas Works and Brewery at 

 Brentford, and only separated by a wall from the exceedingly 

 busy High Street, is an excellent example of this. Either as an 

 isolated specimen, for planting in groups, or for avenues, the 

 maidenhair tree is equally desirable. Propagation is by seeds, 

 and the varieties are grafted on stocks of the type. It has no 

 value for silvicultural purposes.
