so beautifully lobed, shakes the light from its healthy 

 foliage in flashes of white fire. 



As you follow the Walk back, westward, just as you 

 come to the cross-walks before mentioned, in the north- 

 easterly corner of the junction, two Scotch elm stand 

 side by side. Back of these, up on the ridge of rock 

 that rises abruptly, you will find a good specimen of 

 the chestnut oak. You can tell it easily, even at a 

 distance, by its distinctive leaves. These are obovate 

 and wavy margined, running in coarse easy cuttings, 

 like an old-fashioned cookie. On the undersides of 

 the leaves the ribs show prominently, about ten to 

 sixteen pairs, usually. It stands a little southeast of 

 the lamp that guards the north fork of the crossways 

 here. 



Before we take this northerly trend of the Walk 

 (the one which goes on under the Arch ahead) there 

 are some things ' to see along the left branch of the 

 junction here. 



Up the bank on your right as you go westward, 

 there is a pretty young hawthorn of the variety coc- 

 cinea. It stands about midway between a Scotch elm 

 and a cottonwood. The cottonwood you can tell by 

 its spade-shaped leaves and flattened leaf stems, the 

 hawthorn by its thorns. This hawthorn is commonly 

 called the scarlet-fruited hawthorn on account of the 

 very large (half an inch) round or pear-shaped scarlet 

 berries it bears in September. The leaf of this haw- 

 thorn is of a beautiful light green, very regularly lobed, 

 and roundish ovate in form. It is a thin leaf compared 

 with the leaves of the other hawthorns in the Park.
