ilary jockeyed skilfully through, kept on descending into a narrow cleft in the slope. The walls rose almost perpendicularly on either side. About fifty feet down there was a sharp turn and the gorge angled downward for another fifty feet. When the flier came to rest at the bottom, it was securely hidden in a slanting cleft, some forty feet wide and several hundred long. A mountain brook brawled at one side, assuring plentiful water. The outside world was absolutely invisible. Perpetual twilight reigned; only a pale dim religious light filtered through.
"Just the thing," Wat exulted. "We'll never be found here, no matter how much they search, unless someone actually stumbles into the opening. There's almost eighty feet of solid rock above us, and their search beams only penetrate about ten to fifteen."
"Splendid." Hilary said. "Now we've got to get to work."
For two days they toiled incessantly. A rope ladder was fabricated to insure ease of entrance and exit without recourse to the ship. Wat, as the least conspicuous, was delegated to scour the countryside and bring in stores of provisions. The bottom of the gorge was leveled off with infinite labor. Rough wood shelters were erected. Spares and electrical equipment to replace worn parts in the Vagabond were also purchased by Wat, in cautious small purchases. It necessitated long trekking through mountain trails, but there was no murmur from him. The search, he reported, seemed to be slackening. Only the routine guards whizzed by on the conveyors, and the usual Mercutian fliers that kept to the regular air lanes.
At last even Hilary was satisfied. He was ready now for the plan that had been slowly forming in his mind during the days of their flight and of work. He was going to attempt a rescue of Joan. She had never left his thoughts once; he was burning with inward anxiety, though his face was a mask to cover his true feelings.
he last evening he sat with the others within one of the wooden shelters. A huge fire of fragrant pine knots blazed up a crude boulder chimney.
