In the semi -arid parts of the west where a bit of marsh is the one 

 green acre when the hills and valleys have turned brown in sum- 

 mer, the marsh birds have a peculiar charm. The red-wing, with 

 his black coat and the gleam of keen red from his epaulettes, is a 

 strong noie in the landscape, but best of all is his flute-like o-ka-lee, 

 with its cool suggestions of marsh grass and cat-tails.
