The beast is known as the South American tiger, and is by far the most powerful and dangerous of tropic beasts of prey. It is swift enough to capture horses on the open pampas and strong enough to drag them away after the kill. In some of the countries south of the Isthmus the jaguar is a menace to the inhabitants, and settlements have been deserted because of them. It is rarely that one is found as far north as the Isthmus.
