82 PRACTICAL FORESTRY.

 breezes to keep them in health and insure vigorous 

 growth, for a stagnant atmosphere is no more to be 

 desired than stagnant pools of water, but unfortunately,

 extensive plantations. The poplars and willows have 

 been most extensively planted, probably, because they 

 could be easily obtained and readily propagated by
