pean variety, as you can distinguish by their entire, 

 cihate or hairy margins, so different from the strongly- 

 toothed leaves of our native beech. The leaves of these 

 trees come out a deep dark crimson purple in the spring 

 and hold that color late into the summer. Their 

 bark is a fine light gray, and the swing of their 

 branches is noticeably horizontal from rather short, 

 squatty trunks. They are beautiful trees and well 

 worth your careful consideration. As you follow the 

 path along, it bends gently here to the southeast, and

 and flowers early in March or April before its leaves 

 come out. Its flowers are greenish-brown. 



In the next bend of the Walk, on your left, you will 

 have to stop surely to look at the handsome masses of 

 the smooth sumac which fling out scarlet and orange 

 in such beautiful blendings in autumn. The easiest 

 way to tell a smooth sumac from its twin brother, the 

 staghorn (for the leaves are very much alike) is to 

 look at the branches. The branches of the smooth 

 sumac are beautifully smooth, a clean, clear pinkish-red 

 or magenta-crimson, overlaid with the loveliest of 

 lilac bloom. The branches of the staghorn sumac are 

 as dififerent as can be — covered with a sticky pubes- 

 cence. This pubescence, when the leaves of the bush
