a stocky yellow birch. You know it at once by its 

 silvery gray-green bark tinged with copper. The bark 

 peels and curls in shreds and frayed ends which give 

 it a ragged appearance all its own. 



Nearer the Walk stands a hackberry, identified 

 easily by the warty knobs and ridges on its trunk, 

 usually more pronounced on the bark near the ground. 

 If the warty ridges do not satisfy you, look at its 

 lop-sided long egg-shaped leaves which are very rough 

 on the uppersides and hairy on the undersides. The 

 fruit of the tree is a globular drupe or berry on a

 purple, when ripe in the autumn. 



In the corner of the Walk, close by the water, on

 to a little peninsula which juts out into the Lake, just 

 north of Scarlet Island. A curved rail bounds the 

 Walk and cuts it off from this peninsula. If you 

 step over it and follow the shore of the Lake around 

 this peninsula you will find a fine American elm just 

 beyond the rail, then some umbrella trees, with their 

 large paddle-like leaves, and conspicuous crimson 

 fruits in September; then European tree alder, tulip

 This is an extremely interesting tree and you will

 You can tell it by its opposite leaves which are odd- 

 pinnate and made up of about nine (there may
