implies, spreads by underground shoots which grow 

 so rapidly and so thickly that the tangled masses be- 

 come thicket-like. It is a handsome shrub in winter. 

 Then its ruddy branches, noticeably streaked with fine 

 gray lines, brighten and glow in brilliant crimson, mak- 

 ing a rich sight against the snow. Its leaf is of a 

 lighter green, narrower than the flowering dogwood's, 

 and pointed. In June this shrub blooms and breaks 

 in flat conspicuous cymes of white flowers, and these 

 are succeeded in late August by gray-blue or lead- 

 colored berries. Just behind this Cornus, toward the 

 Drive, is a fine mass of American elder, with compound 

 leaves of from seven to eleven leaflets. The lower 

 leaflets are often three-parted. 



A little further on you come to the fork of the Walk 

 by the lamp and the stairs leading from the Plaza 

 Entrance, whence we came down to go around the 

 Pond. 



Now let us go back to the first fork of the Walk 

 east of the Stone Bridge, and follow its left-hand 

 branch, northeasterly toward the Drive. As you come 

 near to where this branch opens out into the drive 

 walk, on your right you pass a compact hawthorn with 

 rather triangular or heart-shaped leaves. These leaves 

 are of a beautiful dark lustrous green, and are from 

 three to five-lobed. This tree is a fine type of the 

 Washington thorn, Cratcegns cordata. It flowers hand- 

 somely in May or June in terminal white corymbs. 

 These change into small coral red berries about the 

 size of small peas, are ripe in September, and remain 

 hanging on the tree long after the leaves have fallen,
