Nest. — A wide platform of flags and rushes in a

On the big unfenced prairies and the treeless 

 expanse of marsh where there is nothing to hide 

 a lurking foe, you find the sandhill cranes, some- 

 times in small migracing flocks but usually in 

 pairs, stalking about in dignified but ever watch- 

 ful manner, stretching up to nearly a man's 

 height to survey the surrounding country, then 

 stooping to probe the earth for worms, catch a 

 distant grasshopper, or spear a luckless frog or 

 minnow. Let an enemy appear in the distance, 

 and the long necks are up, and one of the most 

 powerful, far-reaching of bird-notes rings out with its alarm chal- 

 lenge, a prolonged bugle-like cry, deeper and heavier than the 

 loon's, and often heard a mile away. With a quick run the splendid 

 birds moimt on the wing, the bugle-notes resounding rhythmically 

 with only the space of an inspiration between as they fly ; and 

 though their calls mellow in the distance, the cranes vanish as 

 specks in the air before the sound of their magnificent voices is en- 

 tirely lost. Vkunon Bailky.
