Edgar Caswall tortured his brain for a long time unavailingly, to think of some means of getting rid of what he, as well as his neighbours, had come to regard as a plague of birds. At last he recalled a circumstance which promised a solution of the difficulty. The experience was of some years ago in China, far up-country, towards the head-waters of the Yang- tze-kiang, where the smaller tributaries spread out in a sort of natural irrigation scheme to supply the wilderness of paddy-fields. It was at the time of the ripening rice, and the myriads of birds which came to feed on the coming crop was a serious menace, not only to the district, but to the country at large. The farmers, who were more or less afflicted with the same trouble every season, knew how to deal with it. They made a vast kite, which they caused to be flown over the centre spot of the incursion. The kite was shaped like a great hawk; and the moment it rose into the air the birds began to cower and seek protection--and then to disappear. So long as that kite was flying overhead the birds lay low and the crop was saved. Accordingly Caswall ordered his men to construct an immense kite, adhering as well as they could to the lines of a hawk. Then he and his men, with a sufficiency of cord, began to fly it high overhead. The experience of China was repeated. The moment the kite rose, the birds hid or sought shelter. The following morning, the kite was still flying high, no bird was to be seen as far as the eye could reach from Castra Regis. But there followed in turn what proved even a worse evil. All the birds were cowed; their sounds stopped. Neither song nor chirp was heard--silence seemed to have taken the place of the normal voices of bird life. But that was not all. The silence spread to all animals. The fear and restraint which brooded amongst the denizens of the air began to affect all life. Not only did the birds cease song or chirp, but the lowing of the cattle ceased in the fields and the varied sounds of life died away. In place of these things was only a soundless gloom, more dreadful, more disheartening, more soul-killing than any concourse of sounds, no matter how full of fear and dread. Pious individuals put up constant prayers for relief from the intolerable solitude. After a little there were signs of universal depression which those who ran might read. One and all, the faces of men and women seemed bereft of vitality, of interest, of thought, and, most of all, of hope. Men seemed to have lost the power of expression of their thoughts. The soundless air seemed to have the same effect as the universal darkness when men gnawed their tongues with pain.
