This shape is a graceful one, something between that of a grebe and a guillemot. One might say that a guillemot had been sent to a finishing-school and had very much profited by it; but this is not to imply that the grebe—I am thinking of Podiceps Cristatus—is slighted in the comparison—no bird that swims need think itself so. Much there is grebe-like in manner and action, and in shape, except for the crest.
