leaves. At the oend of the Walk, as it turns down 

 southeasterly to meet the fork, is a fine white oak with 

 its leaves cut into about nine lobes. Just back of this 

 oak, southeast of it, is black cherry, with rough, scaly 

 bark and shining, glossy, taper-pointed leaves. South- 

 east of the cherry is pin oak, with its leaf-lobes bristle- 

 tipped and rounded out by deep bays or sinuses re- 

 minding you of the scarlet oak's leaves. But if you 

 look at the slender yellowish petioles of these leaves you 

 will not confuse them with the stout leaf-stalks of the 

 scarlet. About opposite the point of the fork here, on 

 the northerly side of the Walk, is another pin oak, and 

 west of this, back (north) of the Walk is a good mock- 

 ernut hickory. The mockernut you can tell by its large 

 buds, its large leaves (compound), whose leaf-stems 

 are very pubescent, as are also the undersides of the 

 leaflets. The leaflets run in sevens and nines, usually in 

 sevens. Beyond the fork of the Walk, on the southerly 

 side, down the bank a little, is English yew, with dark 

 green (uppersides), flat, sharply tipped leaves, seem- 

 ingly arranged in a two-ranked manner on the branch. 

 The leaves are linear, that is, with edges nearly parallel, 

 and on the undersides are yellowish green a mark 

 which will distinguish this tree for you from the Ceph- 

 alotaxus, whose leaves are whitish on the undersides. 

 Just beyond the yew stand several clumps of Catesby's 

 andromeda, low bushes of thick, leathery, pointed 

 leaves on short reddish leaf-stems. Beyond these, on 

 either side of the Walk, are the two swamp white 

 oaks of our quest. Note the differences in the leaves 

 of the two trees. As has been said above, the one on
