From Roy Chapman Andrews' excellent book 'Across Mongolian Plains' published in 1921.

Unfortunately I did not reload the camera with a fresh roll of film and thereby missed one of the most unusual and interesting pictures which ever could be obtained upon the plains.

The tents were already in sight when a wolf suddenly appeared on the crest of a grassy knoll. He looked at us for a moment and then set off at an easy lope. The temptation was too great to be resisted even though there was a strong possibility that we might be stalled in the desert with no gas.

The ground was smooth and hard, and our speedometer showed forty miles an hour. We soon began to gain, but for three miles he gave us a splendid race. Suddenly, as we came over a low hill, we saw an enormous herd of antelope directly in front of us. They were not more than two hundred yards away, and the wolf made straight for them. Panic-stricken at the sight of their hereditary enemy followed by the roaring car, they scattered wildly and then swung about to cross our path.

More than a thousand antelope were running diagonally across our course. It was a sight to stir the gods a thing to give one's life to see.

The wolf dashed into their midst and the herd divided as though cut by a knife. Some turned short about, but the others kept on toward us until I thought we would actually run them down. When not more than fifty yards from the motor they wheeled sharply and raced along beside the wolf.

To add to the excitement a fat, yellow marmot, which seemed suddenly to have lost his mind, galloped over the plain as fast as his short legs could carry him until he remembered that safety lay underground; then he popped into his burrow like a billiard ball into a pocket. With this strange assortment fleeing in front of the car we felt as though we had invaded a zoological garden.

The wolf paid not the slightest attention to the antelope for he had troubles of his own. We were almost on him, and I could see his red tongue between the foam-flecked jaws. Suddenly he dodged at right angles, and it was only by a clever bit of driving that Charles avoided crashing into him with the left front wheel.

All this had happened with an unloaded camera in the automobile. I had tried desperately to adjust a new roll of film, but had given up in despair for it was difficult enough even to sit in the bounding car. Were I to spend the remainder of my life in Mongolia there might never be such a chance again.
