The nights were never really dark until toward morning, when the stars seemed to dim and the moon dipped below the horizon. Sometimes there were a few drifting clouds, but they never obscured the sky long enough to be utilized as a mask. So Steve decided to make his attempt at the dark hour preceding dawn and made Orissa go to bed and get what sleep she could. She said her good-byes to the others then, so it would not be necessary to disturb them at the time of departure.
At three o'clock her brother called her and told her to get ready. Chesty and Steve were seated in the launch when the girl arrived on deck, and she quickly took her place. While it was much darker than it had been earlier in the night, Orissa found she could see near-by objects quite distinctly. Four of the crew, headed by Captain Krell, were standing by to lower the launch over the side, and as the owls were hooting their most dismal chorus their screams drowned any noise made by the windlass.
No sooner had the launch touched the surface than Chesty dipped his scull in the water and with a dexterous motion sent the little craft forward toward the mouth of the inlet. They might have been seen from the shore had the Mexicans been alert, but at this hour many who were supposed to be watching had fallen asleep, and if any remained awake their eyes were not turned upon the waters of the tiny bay. Quite noiselessly the launch moved on and presently turned the point of rock at the right.
Orissa stifled a cry and Steve's heart gave a bound as the bow of the launch pointed straight at the big boat of Ramon, scarcely ten feet distant; but Chesty saw the danger, too, and a sharp swing of the scull sent the light craft spinning around so that it just grazed the side of the Mexican's boat, in which all the occupants were fast asleep.
Next moment they had passed it, and still Chesty continued sculling, as it was not safe as yet to start the engines. But when they had skirted the shore for such a distance that the screeching of the owls would be likely to drown the noise of their motor, Steve started the machinery and the launch darted away at full speed.
Half an hour later they crept between the big rock and the bluff and were safe in the deep hollow at the foot of the ravine, having accomplished the adventure so easily that they marvelled at their own success.
"Strikes me as a good omen," remarked Orissa, cheerfully, as they disembarked and drew the launch upon the sands. "I hope the luck will follow you on your return, Chesty."
"Me?" replied the big boy. "Why, nothing ever happens to me. Let us hope the good luck will follow you and Steve, on whom the safety of the entire party now depends. What first, Steve?
"The tent. We must get that down before daybreak, so they won't see us working on it from the bay, and interfere with our proposed flight."
Orissa led the way to the bluff and at once Steve and Chesty began tumbling the rocks from the edges of the canvas. This was no light task, for the girls had erected a solid parapet in order to defy the wind; but just as the first streaks of dawn appeared the tent came down and they hastily seized the canvas, added it to the covering of the upper plane, which had been inside the tent, and lugged it all down the incline to where the frame of the Aircraft lay.
