Herons and Bitterns 



when these bitterns, like all their kin, step boldly out of their 

 retreats and indulge in longer flights from home. Many men of 

 science have thought the powder-down tracts on their bodies 

 glow with phosphorescent light in the dark and attract fish 

 to the water's edge, where the bird stands motionless, ready to 

 transfix a victim with its beak. But as yet this is only an inter- 

 esting theory that has still to be Droved.

The Japanese artists, "on many a screen and jar, on many 

 a plaque and fan, "have taught some of us the aesthetic value 

 of the heron and its allies birds whose outstretched necks, long, 

 dangling legs, slender bodies, and broad expanse of wing give 

 a picturesque animation to our own marshes. But American 

 artists seek them out more rarely than shooters, and a useless 

 mass of flesh and feathers lies decomposing in many a morass 

 where the law does not penetrate and the rifle ball does. Long- 

 fellow, in "The Herons of Elm wood," paints a word picture of
