Passing out through the farm garden on his way to the lanes beyond, where he hoped to recapture the comfortable sense of peacefulness that was so lacking around house and hearth—especially hearth—Crefton came across the old mother, sitting mumbling to herself in the seat beneath the medlar tree. ‘Let un sink as swims, let un sink as swims,’ she was repeating over and over again, as a child repeats a half-learned lesson. And now and then she would break off into a shrill laugh, with a note of malice in it that was not pleasant to hear. Crefton was glad when he found himself out of earshot, in the quiet and seclusion of the deep overgrown lanes that seemed to lead away to nowhere; one, narrower and deeper than the rest, attracted his footsteps, and he was almost annoyed when he found that it really did act as a miniature roadway to a human dwelling. A forlorn-looking cottage with a scrap of ill-tended cabbage garden and a few aged apple trees stood at an angle where a swift-flowing stream widened out for a space into a decent-sized pond before hurrying away again through the willows that had checked its course. Crefton leaned against a tree-trunk and looked across the swirling eddies of the pond at the humble little homestead opposite him; the only sign of life came from a small procession of dingy-looking ducks that marched in single file down to the water’s edge. There is always something rather taking in the way a duck changes itself in an instant from a slow, clumsy waddler of the earth to a graceful buoyant swimmer of the waters, and Crefton waited with a certain arrested attention to watch the leader of the file launch itself on to the surface of the pond. He was aware at the same time of a curious warning instinct that something strange and unpleasant was about to happen. The duck flung itself confidently forward into the water, and rolled immediately under the surface. Its head appeared for a moment and went under again, leaving a train of bubbles in its wake, while wings and legs churned the water in a helpless swirl of flapping and kicking. The bird was obviously drowning. Crefton thought at first that it had caught itself in some weeds, or was being attacked from below by a pike or water-rat. But no blood floated to the surface, and the wildly bobbing body made the circuit of the pond current without hindrance from any entanglement. A second duck had by this time launched itself into the pond, and a second struggling body rolled and twisted under the surface. There was something peculiarly piteous in the sight of the gasping beaks that showed now and again above the water, as though in terrified protest at this treachery of a trusted and familiar element. Crefton gazed with something like horror as a third duck poised itself on the bank and splashed in, to share the fate of the other two. He felt almost relieved when the remainder of the flock, taking tardy alarm from the commotion of the slowly drowning bodies, drew themselves up with tense outstretched necks, and sidled away from the scene of danger, quacking a deep note of disquietude as they went. At the same moment Crefton became aware that he was not the only human witness of the scene; a bent and withered old woman, whom he recognised at once as Martha Pillamon, of sinister reputation, had limped down the cottage path to the water’s edge, and was gazing fixedly at the gruesome whirligig of dying birds that went in horrible procession round the pool. Presently her voice rang out in a shrill note of quavering rage:

‘’Tis Betsy Croot adone it, the old rat. I’ll put a spell on her, see if I don’t.’

Crefton slipped quietly away, uncertain whether or no the old woman had noticed his presence. Even before she had proclaimed the guiltiness of Betsy Croot, the latter’s muttered incantation ‘Let un sink as swims’ had flashed uncomfortably across his mind. But it was the final threat of a retaliatory spell which crowded his mind with misgiving to the exclusion of all other thoughts or fancies. His reasoning powers could no longer afford to dismiss these oldwives’ threats as empty bickerings. The household at Mowsle Barton lay under the displeasure of a vindictive old woman who seemed able to materialise her personal spites in a very practical fashion, and there was no saying what form her revenge for three drowned ducks might not take. As a member of the household Crefton might find himself involved in some general and highly disagreeable visitation of Martha Pillamon’s wrath. Of course he knew that he was giving way to absurd fancies, but the behaviour of the spirit-lamp kettle and the subsequent scene at the pond had considerably unnerved him. And the vagueness of his alarm added to its terrors; when once you have taken the Impossible into your calculations its possibilities become practically limitless.

Crefton rose at his usual early hour the next morning, after one of the least restful nights he had spent at the farm. His sharpened senses quickly detected that subtle atmosphere of things-being-not altogether well that hangs over a stricken household. The cows had been milked, but they stood huddled about in
