“There is something doing, then?” she exclaimed.

“There is likely,” he answered, grimly, “to be a great deal doing!”

The two men who stood upon the hill, and Peter Ruff, who lay upon his stomach behind a huge boulder, looked upon a new thing.

Far down in the valley from out of a black shed—the only sign of man’s handiwork for many miles—it came—something grey at first, moving slowly as though being pushed down a slight incline, then afloat in the air, gathering speed—something between a torpedo with wings and a great prehistoric insect. Now and then it described strange circles, but mostly it came towards them as swift and as true as an arrow shot from a bow. The two men looked at one another—the shorter, to whose cheeks the Cumberland winds had brought no trace of colour, gave vent to a hoarse exclamation.

“He’s done it!” he growled.

“Wait!” the other answered.

Over their heads the thing wheeled, and seemed to stand still in the air. The beating of the engine was so faint that Peter Ruff from behind the boulder, could hear all that was said. A man leaned out from his seat—a man with wan cheeks but blazing eyes.

“Listen,” he said. “Take your glasses. There—due north—can you see a steeple?”

The men turned their field glasses in the direction toward which the other pointed. “Yes!” they answered. “It is sixteen miles, as the crow flies, to Barnham Church—thirty-two miles there and back. Wait!”

He swung round, dived till he seemed about to touch the hillside, then soared upwards and straight away. Peter Ruff took out his watch. The other two men gazed with fascinated eyes after the disappearing speck.
