is close to land: he has left his earth-chest. But he has yet to get on shore. In the night he may lie hidden somewhere; but if he be not carried on shore, or if the ship do not touch it, he cannot achieve the land. In such case he can, if it be in the night, change his form and can jump or fly on shore, as he did at Whitby. But if the day come before he get on shore, then, unless he be carried he cannot escape. And if he be carried, then the customs men may discover what the box contain. Thus, in fine, if he escape not on shore tonight, or before dawn, there will be the whole day lost to him. We may then arrive in time; for if he escape not at night we shall come on him in daytime, boxed up and at our mercy; for he dare not be his true self, awake and visible, lest he be discovered.”
