Back of the hop tree, by the border of the Lake, you 

 will find another silver bell, and beyond the silver 

 bell, oleaster with its willow-like habit of growth and 

 gray-green silvery leaves. Beyond the oleaster is 

 American elm. 



Coming to the Walk again and following on, you 

 pass a fine American basswood a little beyond the last 

 tulip by the Walk. You cannot mistake it, especially 

 if it is in leaf, for its leaves are large, noticeably lop- 

 sided heart-shaped. As the season advances, the 

 American basswood shows distinct shades of yellow- 

 green in its leaves and if you get to know this tint, you 

 can tell the American basswood afar off. Notice how 

 differently it puts out its branches from the habit 

 of the European linden. A little further on, the Walk 

 throws off to the left a short arm to cross the Drive. 

 As it nears the Bridle Path and Drive, you pass some 

 splendid European silver lindens, very easily known 

 by their smooth bark and cordate leaves, white on the 

 undersides. You can tell them also by their notice- 

 ably sugar loaf form. Crossing the Bridle Path for 

 a moment, in the south-west corner of the little space 

 between it and the Drive, at the left, is Koclreuteria, 

 A lamp-post guards the south-east corner and 

 back of it, by the border of the Drive you meet a fine 

 Japan pagoda tree, then Judas tree with good-sized 

 heart-shaped leaves, then Reeve's spiraea and a fine 

 clump of lilac at the extreme north-easterly end of 

 this island-like space. Directly opposite the lamp- 

 post, on the right of the path is another K&lreuteria, 

 with a young hop tree or shrubby trefoil beside it.
