by taking the Walk on the east of the Drive, where it 

 passes over Transverse Road No. 4. The Walk forks 

 just a little beyond the Transverse Road, and its west- 

 erly Branch will bring you beneath the green canopies 

 of this delightful grove. 



Primus padus. (European Bird Cherry. No. 31.) 

 On the westerly end of the little triangular-shaped bit 

 of ground that stands like an island on the Drive, just 

 as the latter crosses Transverse Road No. 4, you will 

 find a pretty fair specimen of this tree. The trian- 

 gular "island" is at the west branch of the Drive, just 

 before it passes over the Transverse Road, and the 

 bird cherry is on its westerly corner, back of a tulip 

 tree. The tulip tree is on the point of the triangle, 

 and you can tell it by its leaves, which seem to be 

 shorn off straight across the top in a very peculiar 

 way. The bird cherry is a small sized tree, with leaves 

 and flowers much like those of the choke cherry, ex- 

 cept that the flowers, which occur in drooping racemes, 

 are longer and larger than those of the choke cherry. 

 In addition they are very fragrant, while those of the 

 choke cherry are anything but that. The leaves of the 

 bird cherry are about four inches long, and obovate in 

 shape, with bases unequally heart-shaped. They are 

 sharply and doubly serrate. 



Sambucus nigra. (European Elder. No. 18.) As 

 you enter the Park at East One Hundred and Second 

 Street, and take the first left-hand (southerly) Walk, 

 close by the third series of steps, low down at your 

 left, as you go south, you will find this mass. Its 

 leaves are made up of five to nine leaflets. In June
