But, to go on, we find some more yellow-woods 

 and then three very beautiful European beeches. Com- 

 pare their soft, toothless leaves with those of our own 

 beech. Our own is strongly toothed, and looks like 

 a broadened form of the chestnut leaf. Then we 

 come to Norway spruce, sparse and thin, not doing 

 very well for some reason and then to a lusty paper 

 birch, side by side with European beech. Next to 

 these we have a good tall American white ash and 

 beyond the ash, hop tree (Ptelea trifoliata). Then 

 come Kcclrcuteria, American ash again, (close beside 

 the Walk) with its strongly individualized bark, and 

 then sturdy English maple (Acer campestre}. If you 

 should happen to see an English maple bloom don't 

 mistake it for a Norway maple, as I have frequently 

 known people to do. It has its flowers in a corymb 

 like that of the Norway maple but its green is darker. 

 Look at the leaves. They will set you right. A lit- 

 tle open stretch follows and we come to American ash 

 again. Just beyond, indeed almost beside it, we meet 

 an evergreen which at once arrests attention by its 

 beautiful dark green short blunt leaves. If you look 

 at its bark you will see that it is dashed and splashed 

 with grayish-white. This grayish-white is resin and 

 the tree is a fine specimen of Oriental spruce (Picea 

 Orientalis). It is distinctly conical in form and you 

 can tell it by this shape, and by its blunt, short, dark 

 green needles scarcely half an inch long. 



Up to this point, easily marked by the conical form 

 of the Oriental spruce, you have passed on your left, 

 beginning at the Irving Statue, single leaved ash, Eu-
