along its stem it is marked with darker tinges of 

 gray, which give you the idea of bands put around the 

 trunk. But if the bark fails to fix it for you, look at 

 the ovate or heart-shaped leaves, which are lobed va- 

 riously, like the usual mulberry leaves, mitten form, 

 with the thumb on either side or perhaps both thumbs 

 on the same mitten. The leaves are very rough on 

 the uppersides but soft and downy on the undersides. 

 The flowers of this tree are not very striking. They 

 occur in inconspicuous greenish catkins in the spring. 

 On old trees the leaves are scarcely lobed at all. 



Push on from the paper mulberries a little and strike 

 off from the path to the lake border. At a point there, 

 about opposite the Japan silver fir, on the upper Walk 

 of the hill, you will be delighted to see a good speci- 

 men of the smooth alder. Its little black "cones" hang- 

 ing all through it tell you it is "alder" and its thick, 

 finely serrate, smooth leaves, green on both sides, tell 

 you it is the Alnus serrulata. The leaf is obovate in 

 shape, acute at the base, but its margin is very finely 

 serrate. 



Go up the hill again now to the middle path and 

 see if you can find the alternate-leaved dogwood which 

 stands near the Walk a little way along. You will 

 know it first of all by its alternate leaves. But its 

 bark, quite different from that of the flowering dog- 

 wood, is ashy gray. Its leaves are noticeably taper 

 pointed. If you are passing near here in late May, 

 you may see its flowers, in large white flat cymes. 

 These change into bright blue berries on reddish stalks.
