haw, is a white mulberry with shining green mitten- 

 shaped leaves. Beyond the rock, an American elm 

 sweeps up its vase-like form, and, diagonally across 

 the Walk from it, is a Norway maple, full foliaged 

 and lusty. About in line with the next abutment of 

 rock, but close by the border (right) of the Walk, 

 is scarlet oak with bristle-tipped leaves, and just be- 

 yond it, a pignut hickory. Beyond the hickory is

 pignut has compound leaves, with the leaf stem smooth.

 on the right (north) of the Walk. This mass is quite

 mountain sumac garnishes its southeastern corner. 

 This sumac you easily recognize by the wing along 

 the leaf-stem and between the leaflets. Up the rock, 

 and back of the sumac an old black cherry lifts its 

 shaggy scaly bark. Down in the southwesterly corner 

 of the rock mass is a whispering chatty gathering of 

 the Japan zebra grass. How lovely it is, with its 

 handsome bands (across the leaves) of green and 

 white. 



Near the Mineral Spring House, beyond the rock 

 mass here, the Walk throws off an arm to the right 

 (northerly) which meets the Border Walk of the Drive 

 beyond. This arm of pathway has a very interesting 

 tree to show us — the white beam tree of the mountain- 

 ash tree family. It stands on the right (east) of the 

 path, about opposite the short branch of Walk that 

 runs in behind Mineral Spring House. This tree, from
