Then he gave a low, soft whistle. The opossums looked up, but did not move. There was a piece of stick within reach of his hand, and picking it up, he whirled it toward them. They looked up again, but still did not move.

Slowly drawing himself out of the tent so as not to disturb the others, Chap rose to his feet and approached the opossums. One of them turned and ambled slowly to a short distance, but the other stood still.

Chap walked close up to him, but the creature merely arched its back and looked at him.

Picking up a stick which was lying near the ashes, Chap gave the stupid creature a little punch. The opossum merely twisted itself up a little and opened its mouth.

“Upon my word!” said Chap; “if you are not the tamest wild beasts in the world! I don’t believe either of you ever saw a man before, and don’t know that you ought to be afraid of him. But I’m not going to hurt a non-resistant. You can go ahead and eat your supper, for all I care.”

And so he slipped quietly back into the tent, and left the opossums to continue their meal.

It might have been supposed that when Chap did close his eyes, he would sleep longer than the others, but this was not the case. Either because he did not rest well in a new place, or because his mind was disturbed by his responsibilities as captain of the party, he awoke before any of the others. It was broad daylight, and again he slipped out of the tent without disturbing any of his companions.

The opossums were gone, and Chap walked along the water’s edge, looking at the hosts of birds which were flying above him. There were gulls and many others which he did not know, and near the other side of the river was a small flock of very large birds, which he supposed must be pelicans.

As he walked round the little clump of trees, under which the tent was pitched, he saw upon the sand, near the water’s edge, something which made his heart jump.

It was an alligator, the first Chap had ever seen out of a menagerie. It was about eight feet long, and was lying in the sunshine, with its head toward the water.
