72 THE BIRD WATCHER

more as a hand here than a mouth—yet what is done 
with entire ease is as though it were not done at all. 
Even so do the guillemots—the common ones, I mean 
—but then, they used to fight for their fish. Here 
I saw little or nothing of any real attempt on the part 
of one bird, to take the fish from another. 
In swimming under water the black guillemot uses
