“It’s a wonder the government wouldn’t send gunboats down here!” shouted Jimmie in his chum’s ear. “It’s bananas to beams that both those steamers are carrying contraband goods in the shape of Chinks and opium.” “They can carry anything they like, so long as they let us alone!” Carl answered back. For a time both machines passed straight out to the west, rising slightly as they advanced. Then Ben turned away to the south, evidently with the intention of passing above the deck of the steamer which lay in front of the second beacon. Jimmie, of course, followed his example, and directly both flying machines dipped down to within a hundred yards of the deck. There was no longer any doubt concerning the mission of the vessel. At least a score of Chinamen were in sight. The appearance of the flying machines naturally created great excitement on the deck below. Hairy-faced sailors shook their fists violently upward, and the Chinamen were driven like cattle into a hatchway and passed out of sight. “We haven’t got a line on the bank burglars yet!” Jimmie shouted into Carl’s ear, “but we’ve butted in on a mighty prosperous game just the same!” Ben, of course, was beyond the reach of his chum’s voice, but he expressed his acknowledgment of the situation by turning in his seat and waving an arm in the direction of the _Louise_. As soon as the two aeroplanes passed beyond the beacon on the headland, they turned to the sea again and moved out some distance from the shore. It was the intention, of course, to pass down the coast in quest of another landing-place, and they swung out to sea in order that their movements might not be observed in case they were watched from the mountain. Perhaps three miles from the second beacon and schooner they turned sharply to the east and lifted to an altitude sufficient to enable them to cross the line of summits which guarded the coast. They proceeded in this direction for a short time passing over what seemed to them to be the highest peak of the Sierra de Santa Lucia, and then dropped down into what appeared, in the dim light of the stars, to be a round bowl of a valley between two parallel ridges. It was desperate and creepy work, settling down to earth, but the usual luck of the boys prevailed, and before long they found themselves in a grassy valley some two thousand feet below the summit. They all shivered as they stepped out of their seats and gathered in a group. “What did you see when you crossed the summit?” asked Ben, turning to Jimmie. “Anything particular attract your attention?” “To tell you the truth,” the boy replied, “I was so frightened, and so busy following your lead, that I saw only the neck-breaking places below and the stars above.” “Well,” Ben went on, “if you had taken a good look to the north, you would have seen a flying machine hovering over the headland where we saw the first signal.” “A flying machine?” repeated Carl. “That’s what I said!” insisted Ben.
