From 'Marco Polo' by Isaac Asimov published in 1926
The Great Khan has many leopards and lynxes kept for the purpose of chasing deer, and also many tigers which are larger than the Babylonian lions, have good skins and of a handsome colour — being streaked on the sides, with white, black, and red stripes. They are active in seizing boars, wild oxen and asses, bears, stags, roebucks, and other beasts that are the objects of sport.
It is an admirable sight, when the tiger is let loose in pursuit of the animal, to observe the savage eagerness and speed with which he overtakes it. His Majesty has them conveyed for this purpose, in cages placed upon cars, and along with them is confined a little dog, with which they become familiarized.
The reason for thus shutting them up is, that they would otherwise be so keen and furious at the sight of the game that it would be impossible to keep them under the necessary constraint. It is proper that they should be led in a direction opposite to the wind, in order that they may not be scented by the game, which would immediately run off, and offer no chance of sport.
His Majesty has eagles also, which are trained to catch wolves, and such is their size and strength that none, however large, can escape from their talons.
