"When does the train reach our station?" Kamuka asked.

"Not for about an hour," calculated Chandra, "counting change of engines. Before they come back to look for us, we will be on the Grand Trunk Road."

Despite his assurance, Chandra was moving rather cautiously, but for another reason. He was looking from side to side, for they were in the jungle now and there was no telling what night creatures might still be on the prowl. Chandra knew this from occasional experience in such a setting, as any Indian boy would who had lived in a native village like Supari. But Kamuka, the boy from Brazil, recognized it instinctively, for he was jungle born and bred, though in the opposite hemisphere.

"Remember, Biff?" queried Kamuka. "The time the big jaguar jumped at you?"

"I remember," replied Biff, "because it was you who stopped it, Kamuka."

"I just helped," said Kamuka. "But this jungle reminds me of jaguars. Do they have them here?"

"They have cheetahs, leopards, and tigers. Those should be enough—and more."

"And big sucuria, too?"

"Yes, they have those." Biff turned to Chandra. "He means a boa constrictor. We ran into a big one up the Amazon, a snake the size of your python."

"What about Macu?" demanded Kamuka.
