violet, indigo flowers clustered in terminal spikes. Its 

 common name is false indigo. Beyond this bush is 

 a little halesia or snow-drop tree with which you no 

 doubt have already become well acquainted. Try to 

 see the halesia in early spring. At that time it seems 

 the very essence of spring itself, and its pearly white 

 flower bells with their hanging clapper-like pistils, 

 seem to ring out "purity, purity, purity," through 

 the leafing trees from all their silent little bell?. There 

 is a music that is soundless and that is the music of 

 a flower to the eye. Such music bells the halesia in 

 spring. But you can know it when it is not in bloom by 

 its bark, which is distinctly marked with longitud- 

 inal lines. Its leaves are very soft and velvety, oblong 

 egg-shape, from two to four inches in length, 

 and finely serrate. If it be in fruit, you can surely 

 know it by its seed which is distinctly four-winged ; 

 hence its name Halesia tetraptera, (tetra, Greek for 

 four and ptera, wing). As we go along, we meet, still 

 on the right, a young Washington thorn (Cratccgus 

 cor data) with small leaves very noticeably triangular 

 in form. It blooms in middle or late May with ter- 

 minal corymbs of white flowers which develop into 

 small scarlet berries in September. These hang upon 

 the tree late into the winter and they are cheery, 

 glowing sights when all the paths are stilled with the 

 driven snow. As you go on south two pretty young 

 black haws lean out over the Walk to you. The sec- 

 ond is very near a lamp-post that stands by the Drive. 

 This will show you where you are. Just beyond the 

 lamp-post is black cherry (Primus scrotina) with
