do not shred off into fine thread-like filaments, like 

 the Adam's needle you found down on Section Num- 

 ber One. Beyond the mound lily, and about south 

 of the center of the Monument, is the pretty pearl 

 bush, cultivated from China for its large white flowers. 

 These have spoon-shaped petals, and come out in long 

 axillary racemes in May or June. It is a beautiful 

 shrub, and the white of its flowers is purity itself. It 

 gets its name from the Latin exo, external, and chorde,

 the far south-westerly corner of the path is Lycium 

 barbarum. Directly back (west) of the Monument 

 is a handsome double-flowered variety of the prairie 

 rose, and at the northwest corner of the path we have 

 fragrant honeysuckle. Directly north of the Monu- 

 ment are two low-growing specimens of the pearl bush. 



On the right of the Walk, as you went around, 

 you passed Rhodotypos (in the corner), then cut- 

 leaved blackberry and bristly locust, opposite the 

 mound lily. The bristly locust is easily identified by 

 its bristly branches and locust leaves. It sprawls 

 about beautifully here, directly opposite the south- 

 easterly corner of the Monument. As you follow the 

 path down the gentle decline to its junction with the 

 Drive Walk, you will see, on your right, as you go 

 northerly, a fine old weeping European silver linden. 



Follow the Drive Walk northwards from this junc- 

 tion, and, about half way to the Arbor beyond, you 

 will pass three fine cottonwoods. These are on the 

 left of the Walk. Beyond these, a little space, on the 

 left again, you will find black alder or common win-
