choppy sea and directly down stream keeping in the swiftest 
part of the current and making a succession of remarkably long 
dives. Although I paddled hard I did not succeed in overtak¬ 
ing it until it turned into the meadow and then I did not get 
nearer at any time than about 100.yards for it doubled on me 
continually and went almost as far under water at each dive 
as a Loon. 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. But from 
the moment 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.
