THE BLACK TERN 27 



ways the terns interest me more than any other water 

 fowl because their provision for swimming seems ahnost 

 unnecessary. In fact, I have never been quite able to 

 understand why they are water fowl at all. They re-

When I was a boy we had very few terns about home. 

 In fact, in Southeastern Iowa it is only occasionally that 

 terns of any kind are seen and those are mostly migrating. 

 However, I used to make occasional trips further north into

 never forget my first trip through " .orth western Ne- 

 braska and Eastern Colorado — not the first time I ever 

 rode through on a train, but the first when I had oppor- 

 tunity to drive over some of this country and become 

 acquainted with its birds and flowers. I happened to
