Crowds of cattle, like mobs, are strangely subject to some sudden impulse. Any seamy-faced old drover will illustrate this fact with stories till midnight, telling how Alkire's cattle resting one morning on Bald Knob suddenly threw up their heads and went crashing for a mile through the underbrush; and how a line of Queen's steers charged on a summer evening and swept out every fence in the Tygart's valley, without a cause so far as the human eye could see and without a warning. Three hundred cattle had crossed, swimming the track of the loop as though they were fenced into it, and I judge there were a hundred in the water, when the remainder of the drove on the south shore made a sudden bolt for the river. The move was so swift and uniform, and the distance to the water so short, that Ump and the ferrymen had barely time to escape being swept in with the steers. The whole drove piled up in the river and began to swim in a black mass toward the north shore. I saw the Bay Eagle sweep down the bank and plunge into the river below the cattle. I could hear Ump shouting, and could see the bay mare crowding the lower line of the swimming cattle. The very light went out of the sky. We forced our horses into the river up to their shoulders, and waited. The cattle half-way across came out all right, but when the mass of more than two hundred reached the loop of the curve, they seemed to waver and crowd up in a bunch. I lost my head and plunged El Mahdi into the river. "Come on," I shouted, and Jud followed me. If Satan had sent some guardian devil to choose for us an act of folly, he could not have chosen better than I. It is possible that the cattle would have taken the line of the leaders against the current if we had kept out of the river, but when they saw our horses they became bewildered, lost their sense of direction and drifted down into the eddy,--a great tangle of fighting cattle. We swung down-stream, and taking a long circle came in below the drove as it drifted around in the outer orbit of the eddy. The crowd of cattle swam past, butting each other, and churning the water under their bellies, led by a half-blood Aberdeen-Angus steer with a ring in his nose. Half-way around we met Ump. He was a terrible creature. His shirt was in ribbons, and his hair was matted to his head. He was trying to force the Bay Eagle into the mass of cattle, and he was cursing like a fiend. I have already said that his mare knew more than any other animal in the Hills. She dodged here and there like a water rat, slipped in among the cattle and shot out when they swung together. On any other horse the hunchback would have been crushed to pulp. We joined him and tried to drive a wedge through the great tangle to split it in half, Jud and the huge Cardinal for a centre. We got half-way in and were flung off like a plank.
