Somewhat later in the day the boy made use of a deep pool of water for that purpose, and was surprised to see, peering up at him, features that were copper-colored from sunburn and exposure to the elements. The outdoor life at home had tanned him somewhat, but nothing in comparison with this.

The weather, while they were in the forest, was dry and pleasant, but the very day they emerged from its confines, a rain poured down that was even heavier than that which had detained them twenty-four hours at Huari. It commenced to fall as they were awakening, and descended in such torrents that any thought of trying to pursue their way while it lasted had to be abandoned. Their shelter-tent was fortunately pitched on a slight elevation, beneath the branches of a large ironwood tree which broke the force of the drops, or rather of the rain-sheets.

Señor Cisneros and Hope-Jones put on rubber coats and dug a shallow trench around the canvas, making a channel toward the river, and for the remainder of the day they sat in the little enclosure, except for a few minutes when one or the other ventured forth for a “breath of fresh air.” All wood in the vicinity was too wet for use as fuel; indeed, there was no spot where they could build a fire, had they had dry timber; so they were compelled to subsist upon smoked meat.

“This is Monday, is it not?” Harvey asked.

“Yes, and a decidedly blue Monday,” was the reply.

Toward evening they voted it the most miserable day of the journey, and their only comfort came from the Peruvian, who assured them that the heavy rains in that season seldom lasted for more than one day.

The rule held in this instance, and soon after dark the clouds were driven away, the moon silvered the dripping trees and bushes, and the travellers were able to emerge from under the canvas. By digging beneath some leaves, they found dried, decayed wood, that served admirably for fuel, and soon had a roaring blaze started, over which they cooked some fish that Harvey had caught during the afternoon.

After leaving the dense forest behind, they followed the Marañon through a much more open country. There were many trees, but they were not so close together, nor were they so tangled with vines, and the undergrowth also became thinner. This was due to a change in the soil, they having passed from the region of black earth to a land that contained more sand. It became quite rocky close to the river, and they were compelled to make frequent detours from the bank because of the boulders through which the stream passed.

One morning all became very much interested in witnessing a body of foraging ants, to which their attention was called by Señor Cisneros.

“These little creatures can be seen only in South and Central America,” he said, “and they have the reputation of being the wisest of all antdom. Look how they are marching in regular phalanxes, with officers in command!”
