It seems as though there 

 were no motion quite as un- 

 dulating and graceful as 

 that of a tree with an abun- 

 dance of fine foliage. This 

 the honey locust has, and 

 about it there is something 

 very interesting. As though 

 to atone for the fact that 

 its leaves are abruptly pin- 

 nate, a growth never as 

 pleasing as when they are 

 terminated by an odd leaf- 

 let, or by a tendril, the end 

 leaflet often again divides 

 itself, and the leaf becomes 

 twice pinnate. In this way 

 it satisfies its desire for a 

 mass of fleecy, light foliage. 

 Growing on the branches 

 just above the axils of the leaves, or where the leaflets grow
