which you can know very easily by its glossy entire 

 leaflets and by the distinct wing along the edge of the 

 leaf stem, between each pair of leaflets. This sumac in 

 autumn time turns a cool crimson, like the brilliant 

 scarlet of the staghorn or the smooth sumac, but all 

 the richer in effect, from its subdued fire. Its glossy 

 leaves give a dark, lustrous glow to the whole mass, 

 which seems to suggest that the shrub is just about to 

 break out into full flame. Proceeding onward, the next 

 fork of the Walk (the sixth from the Sixth Avenue 

 Gate northwards) brings you to some handsome honey 

 locusts, buckthorn, English hawthorn and bristly locust. 

 You can find them easily. One honey locust stands in 

 the very angle of the Walk's fork. It has very dark 

 (almost black) bark, smoothish, save where it is broken 

 by rather clearly-cut ridges. The trunk and branches 

 fairly sprout thorns — strong, fierce-looking things with 

 a kind of three-tined growth which has been sufficient 

 to give the tree one of its names tricanthos (three- 

 thorned). Its genus name, Gleditschia, is from Gled- 

 itsch, a German botanist. This tree exhibits a strange 

 combination of strength and delicacy, strength in its 

 armed trunk, delicacy in its exquisite sprays of com- 

 pound leaves, made up of many small leaflets. The 

 honey locust is of the great pulse family, as is also the 

 locust, and its leaves look like finer, smaller editions of 

 the locust's leaf, having from ten to twenty-four small 

 pinnate leaflets. The honey locust has very conspic- 

 uous fruit, especially noticeable in late autumn and 

 winter, long strap-shaped pods often curled and twisted, 

 at first of a striking orange-yellow, later of a russet
