 comprehension of the vast supply that is required 

 by a tree when we view its foliage, each leaf being 

 employed in receiving and transmitting gases from 

 the air in certain proportions to the plant : these 

 great operations having been effected during the sum-

 tree, they appear .to be injurious to the smaller 

 herbage, but they are more generally dispersed as 

 they part from the sprays by the gales of autumn,
