“The tapir tiger—that is what we call the jaguar. A good name for him. Look there and you see why!”

Jacome indicated a chunk of cooked tapir meat, hanging from a tree branch near the fire. The smell of its favorite food had evidently drawn the “tapir tiger” in from the jungle. But that did not fully satisfy Mr. Brewster.
