As in all tropical localities night came on swiftly, and by the time they had brought all their things to the top of the bluff and started a camp-fire darkness was upon them, lit up only by a few bright stars far overhead. They had brought with them a fair sized tent and Sam and Darry were soon hard at work cutting the necessary poles for erecting the shelter.

“These forests look as if they had never seen the axe of a woodsman,” said Sam. “What immense trees! Some of them must be two hundred feet high.”

The poles were soon cut and then the erection of the tent began. It was placed at a point where the ground sloped a little, which would allow the water to run off in case it rained. It was fastened down with extra heavy stakes so that nothing short of a hurricane would be able to level it.

The tent erected, they took the most valuable of their stores inside, piling them up at the rear. There was a case for their guns, another containing ammunition, and a third medicines, and also several bundles of clothing. They had also brought with them a number of canned goods, coffee, sugar, salt and some jerked beef, in case they should be unable to bring down their own meat. The jerked beef had been purchased at Apure, where there is a large market for beef, both “on the hoof” and prepared. Among the stores were also a bag of flour and a small bag of beans—the latter brought along by Sam, who declared that he was going to have his usual Sunday morning delicacy, no matter what happened.

It was decided by the professor that throughout their stay in the jungle each should take his turn at watching during the night. “There are seven of us all told,” he said. “And that will give each only about an hour apiece, which will be no hardship. Perhaps nothing will come to disturb us, but with one on guard all the others will be able to sleep in comfort.”

The first night in the camp passed without anything unusual occurring. The boys were up bright and early, and Mark discovered a pool at the foot of the waterfall where they might bathe and wash to their hearts’ content. The water was as cool as it was pure and refreshed them wonderfully.

“Makes a fellow feel like living again,” cried Darry, as he splashed around. “I presume that water comes from the very top of yonder mountain.”

“No doubt of it,” returned Mark, “and some of it may be melted snow for all we know.”

Hockley had been too lazy to take a bath, and still lay on the flooring of the tent, snoring lustily. To wake him up, Darry went and pulled him by the foot.

“Hi, you, let go!” cried the sleepy youth, as he sat up. “Can’t you let me sleep?”
