The cargo that the tender carried was far larger than Jack had thought it to be, and the launch was kept busy for nearly two hours plying between the beach and the mother vessel. The men in charge of the unloading worked very hard to get everything ashore before darkness set in, but in spite of their efforts the sun had gone down and twilight was fast coming on when the launch was finally hoisted upon its davits and the Blueflower was ready to maneuver toward the open sea again.
In the half light of evening this was no easy task, and Jack and Mr. Warner watched with interest the careful methods adopted by Captain Wilmoth. But even with all his caution the Blueflower’s steel sides scraped against the hidden granite of Cobra Reef on two occasions and it was only by the quickest kind of action that the vessel was saved from having her hull ripped open.
“Say, but that was as tough a job as I ever want to undertake,” said the captain as he came down from the pilot house after the Blueflower had come to anchor outside the reef. “Did you hear her scrape? That granite would have ripped off a couple of our plates if we had gone ahead six inches further. I surely feel as if I had earned my supper to-night. And I’m going to get it right now. I trust you gentlemen are ready to eat.”
“We are,” was the unanimous reply, and Jack and Mr. Warner accompanied the chief officer down to the saloon, for, you see, it had been decided that they stay aboard the tender overnight and run ashore in the launch next morning.
Day had disappeared entirely and night had settled down by the time they finished supper and came on deck again. Stars were winking overhead and a great round yellow moon was just appearing above the eastern horizon. Over the island the white light from the tower on the promontory flashed periodically, and just below and to the left burned a great bonfire, marking the location of the construction camp. The Blueflower swayed softly at its anchorage, and from the direction of the shore came the deep-toned lullaby of the breakers, softened by distance to a soothing night song. It was a wonderfully calm and clear evening, and it made a lasting impression on Jack. It seemed to him as if the world had not a trouble or a care on all its broad breast, and he too felt singularly contented.
At half-past ten the watch fire on shore had gone out completely, telling plainly that the construction camp was asleep. This suggested retiring to the three individuals on the deck of the tender, which suggestion they were not long in following, for they were all tired, and besides they intended to be astir early the following morning.
By three bells of the first dog watch all on board the Blueflower were awake, and by six o’clock Jack and Mr. Warner had breakfasted and were on deck. Then since all their effects had been moved ashore the night before, there remained nothing for Jack and the engineer to do but shake hands with Captain Wilmoth and their friends among the Blueflower’s crew and start in the launch for Hood Island.
Though the little boat was a sturdy craft, the tide racing through the opening in the reef threw her off her course several times during the trip, and Jack gained a good idea of how treacherous the water of Hood Island was and he could also see, by glancing along the jagged edge of rocks, how the eddies formed and swirled about the Cobra Head. Indeed, though there was practically no sea running, the currents and cross-currents of the tide created waves about the base of the big rock that assumed the proportions of breakers, and dashed spray high in the air as they crashed against the immovable granite.
Mr. Warner saw what Jack was looking at and remarked, “Cobra Head looks like a mighty ugly place, eh, lad? We are not going to have the easiest time in the world building a lighthouse out there. Just think of surveying the site for the tower! Why, in a storm a man wouldn’t stand any more chance on the top of that rock than a straw. The currents are so nasty out there that the seals don’t even attempt to land. They come inside the reef and climb on shore to sun themselves.”
“Seals? Do they have ’em here?” queried Jack, forgetting for a moment about the dangers of Cobra Head.
