sycamore maple with its five-lobed leaves, and then 

 osage orange. This osage orange is one of the oldest 

 in the Park. Back of the osage orange are several 

 beeches of the native type. Opposite the osage orange, 

 on the right of the Walk, is American hornbeam, and 

 out beyond it, almost in line with the hornbeam, is a 

 fine old bur or mossy-cup oak. This tree grows close 

 beside a good sized rock. The rock, by the way, is 

 beautifully covered with Chinese wistaria. The bur 

 oak is a tall tree with light gray, scaly bark, so coarsely 

 furrowed as often to seem scaly. You can pick it out 

 easily by its peculiar leaves, which have, near the mid- 

 dle, two sinuses (the curve or bay between the lobes) 

 opposite each other, cut almost in to the midrib. The 

 leaves are quite large, from six to twelve inches long, 

 and look something like an enlarged edition of the 

 narrow-form leaf of the white oak. But if you fail 

 to find the characteristic "opposite sinuses," look for 

 the corky wings which are almost sure to be present on 

 the younger branches of the tree. If by chance you 

 should find an acorn of the tree, its cup, almost com- 

 pletely grown over the nut and nearly enclosing it with 

 a frouzelly fringe, will tell you at once that the tree 

 is the bur oak or over-cup oak. This name well suits 

 the tree, judging from its acorn. 



A little further on and we have come again to the 

 fork of the Walk by whose easterly branch we pro- 

 ceeded northerly to the Drive, by the Morse Statue. 

 Let us now go back to the first branching of the Walk 

 referred to in this ramble, the first beyond the Shakes- 

 peare Statue, on the Mall, and follow its left arm along
