world, as we note that the pale yellow of these blossoms gleams 

 so vividly through the darkness as to advertise effectively their 

 whereabouts, while their fragrance serves as a mute invitation 

 to the pink night-moth, which is their visitor and benefactor.

HORSE BALM. RICH-WEED. STONE-ROOT. 



Collinsonia Canadensis. Mint Family (p. 16). 



One to three feet high. Leaves. Opposite, large, ovate, toothed,

 black-eyed Susans, which are laughing from every corner and 

 keeping up a gay midsummer carnival in company with the
