stands Scotch elm. Here we are opposite a little arm 

 of Walk which has run in from near Sixty-ninth 

 Street. There are several good specimens of Scotch 

 elm gathered here, and you can know them by the side 

 points near the ends of their leaves. 



Continuing, northwards, near the place where the 

 Walk widens out around a wooden platform through 

 the centre of which an aged pin oak still lives on, flut- 

 tering a few leaves from its lopped branches, you will 

 find, on your right, Turkey oak, and then two horse- 

 chestnuts on your left. About opposite the Turkey 

 oak is European linden, and diagonally northwest of it 

 is sour gum or tupelo. 



The Walk narrows beyond the pin oak in the plat- 

 form, and as you follow it there is a sturdy European 

 beech on the right, with a couple of Scotch elms just 

 beyond. Opposite these, on the left of the Walk, are 

 two silver maples. Beyond, standing in a stalwart 

 cluster, are two stately scarlet oaks. These are fine 

 types, healthy in every way. As you come out upon 

 the Drive Walk, near the Morse Statue, two well grown 

 pin oaks fling their boughs over you. You may some- 

 times confuse a pin oak with a scarlet oak, but one 

 sure way to distinguish them is by their leaf stems 

 the pin oak's is always slender and yellowish; the 

 scarlet is swollen at base, stout, and often tinged with 

 red. 



We will turn to the left here and follow the Drive 

 Walk back to the west and south. Just beyond the 

 pin oak is an elm which will interest you. Look at its 

 tiny leaves, This is the Ulmus parvifolia, from Si-
