After they had succeeded in passing the warriors in the forest they met no delays on their journey and before daybreak arrived at the city. Joe found the house where we had left the airship, but could not get in. He secreted himself and Lucia in a nook between two rear buildings until morning, when the family that inhabited the place arose. By good luck they managed to creep in unobserved and made their way to the roof, where they found the biplane had been left undisturbed. The natives knew nothing of its operation and perhaps regarded the machine with superstitious awe. In overhauling the machine Joe discovered that Lucia understood it as well as he did. She had watched us put it together and repair it after Alfonso’s accident and had listened carefully and intelligently while we were instructed in its use. Now she helped Joe adjust it, and they got it in order just as I was led out for my execution. Peering over the edge of the roof Joe watched me being led away and at first could not understand what was up. But when the entire population not already gathered at the water front hurried after us, he gave a shrewd guess that the hour of my execution was at hand. He knew pretty well what the programme would be. I was to be drowned in sight of the watching Faytans. The water front was not visible from their station on the housetop, but Lucia proposed she should take a flight in the airship and find out how seriously I was in danger. He allowed her to go for two reasons. One was that he believed he could start the machine all right from the roof, which she could not do. And then, if she found a chance to rescue me, we could go back to the ship in the biplane and Lucia and I would both be saved. To go himself meant to leave her there alone upon the roof, in a strange city and surrounded by enemies. Of course her mission was a desperate one at the best; but Joe considered it less hazardous than for her to be left upon the roof, and the biplane could not be trusted to carry three. He questioned Lucia closely, and her knowledge of the machine was more accurate than his own. She had never operated it, but neither had he, for that matter, so in the end he let her go. The biplane was started safely at the first attempt, and Lucia rose well into the air and circled around until she got her bearings and could overlook the tragedy being enacted on the bay. Then, seeing my danger, she headed directly for me—and the result you know. “Where is he now?” I asked Lucia. “Still in the Pearl City,” she replied. “Before I left him he said he would hide until to-night and then make his way back across the island.” “Did he say where he would hide?”
