When it came to the surface it invariably showed 
its whole body or at least as much of it as a Whistler 
or Old Squaw would have shown under similar circumstances. 
ut from the moment when I began chasing it, the loose 
ruff-like plumage of the head was pressed down so tightly 
that the head looked scarce thicker than the slender neck, 
I could not make it fly and finally left it swimming and 
diving.
