to be in one piece, without a joint; though, just when the wind catches them freshly, and drives the bird swiftly along, they are turned slightly upwards toward the tips, through the momentary yielding of the quills. Strange though it may seem, this straightness—almost stiffness—of the wing-contour adds to—nay, makes—the grace of the fulmar petrel's flight, and the pronounced bend at the joint, which, in the gull and kittiwake, causes the forepart of the wing to slope backwards in a marked degree, looks almost clumsy by comparison. The reason, I think, is that the petrel's straight, thin, flat-pressed wings look so splendidly set to the wind, suggesting a graceful ship—lateen-rigged—in fullest sail, whilst the others seem timidly furled and reefed, by the side of them. Sometimes, indeed, the wings do bend just a little—for, after all, they have a joint—but the straight-set attitude is more germane to them, and soon they assume it again, shooting forward so briskly, yet softly, that one seems to hear a soft little musical click.
And thus this dream and joy of glorious motion, this elemental spirit of a bird, floats and flickers along, cradled in air, looking like a shadow upon it, sweeping and gliding, rising and falling, in circles of consummate ease. No, this is not dominion, but union and sweet accord. There is no in-spite-of, no proud compelling, here. Lighter than the air that it rides on, the bird seems married to it, clasps it as a bride.
