bridge, where two others were found, and to Chelsea, where 

 a fourth, and one that might be a variety, were growing. I 

 pointed out the characteristics of each species in growth, 

 branching, bark, fruit and leaves, and especially in the buds. 

 He listened with the most captivating attention, and ex- 

 pressed surprise at my dwelling upon the peculiarities of the 

 buds. "I have never known the buds to be spoken of as

 who was ready and happy to communicate wealth of inform- 

 ation upon every point I could ask about. 



Some days after, I invited all the members of this Society
