To me the most amazing thing was the spectacle of the swifts. It was late for them, near the end of August; they should now have been far away on their flight to Africa; yet here they were, delaying on that desolate east coast in wind and wet, more than a hundred of them. It was strange to see so many at one spot, and I could only suppose that they had congregated previous to migration at that unsuitable place, and were being kept back by the late breeders, who had not yet been wrought up to the point of abandoning their broods. They haunted a vast ruinous old barn-like building near the front, which was probably old a century before the town was built, and about fifteen to twenty pairs had their nests under the eaves. Over this building they hung all day in a crowd, rising high to come down again at a frantic speed, and at each descent a few birds could be seen to enter the holes, while others rushed out to join the throng, and then all rose and came down again and swept round and round in a furious chase, shrieking as if mad. At all hours they drew me to that spot, and standing there, marvelling at their swaying power and the fury that possessed them, they appeared to me like tormented beings, and were like those doomed wretches in the halls of Eblis whose hearts were in a blaze of unquenchable fire, and who, every one with hands pressed to his breast, went spinning round in an everlasting agonized dance. They were tormented and crazed by the two most powerful instincts of birds pulling in opposite directions--the parental instinct and the passion of migration which called them to the south. In such weather, especially on that naked desolate coast, exposed to the fury of the winds, one marvels at our modern craze for the sea; not merely to come and gaze upon and listen to it, to renew our youth in its salt, exhilarating waters and to lie in delicious idleness on the warm shingle or mossy cliff; but to be always, for days and weeks and even for months, at all hours, in all weathers, close to it, with its murmur, "as of one in pain," for ever in our ears.
