Right and left of the horsemen the pioneers of this strange army passed. At one that rolled along the ground, breaking shapelessly and trailing out reluctantly into long grappling ribbons and bands, all three horses began to shy and dance. The master was seized with a sudden, unreasonable impatience. He cursed the drifting globes roundly. "Get on!" he cried; "get on! What do these things matter? How _can_ they matter? Back to the trail!" He fell swearing at his horse and sawed the bit across its mouth. He shouted aloud with rage. "I will follow that trail, I tell you," he cried. "Where is the trail?" He gripped the bridle of his prancing horse and searched amidst the grass. A long and clinging thread fell across his face, a grey streamer dropped about his bridle arm, some big, active thing with many legs ran down the back of his head. He looked up to discover one of those grey masses anchored as it were above him by these things and flapping out ends as a sail flaps when a boat comes about--but noiselessly. He had an impression of many eyes, of a dense crew of squat bodies, of long, many-jointed limbs hauling at their mooring ropes to bring the thing down upon him. For a space he stared up, reining in his prancing horse with the instinct born of years of horsemanship. Then the flat of a sword smote his back, and a blade flashed overhead and cut the drifting balloon of spider-web free, and the whole mass lifted softly and drove clear and away. "Spiders!" cried the voice of the gaunt man. "The things are full of big spiders! Look, my lord!" The man with the silver bridle still followed the mass that drove away. "Look, my lord!" The master found himself staring down at a red smashed thing on the ground that, in spite of partial obliteration, could still wriggle unavailing legs. Then, when the gaunt man pointed to another mass that bore down upon them, he drew his sword hastily. Up the valley now it was like a fog bank torn to rags. He tried to grasp the situation. "Ride for it!" the little man was shouting. "Ride for it down the valley." What happened then was like the confusion of a battle. The man with the silver bridle saw the little man go past him, slashing furiously at imaginary cobwebs, saw him cannon into the horse of the gaunt man and hurl it and its rider to earth. His own horse went a dozen paces before he could rein it in. Then he looked up to avoid imaginary dangers, and then back again to see a horse rolling on the ground, the gaunt man standing and slashing over it at a rent and fluttering mass of grey that streamed and wrapped about them both. And thick and fast as thistle-down on waste land on a windy day in July the cobweb masses were coming on.
