He turned to Chris as the sound of running feet and of the boats being hoisted overboard came loudly in the stillness of the night.

"Now Christopher, my boy, do you go down and go over the side again, and remember what we spoke of a few hours agone!"

The next half-hour was an exhausting one for poor Chris. It was an impossibility for him to keep for long at a time, either his own, or the shape of the porpoise. He had to enter the water under the eyes of the sailors waiting with their oars poised above the sea, in the shape they knew; Christopher Mason. But once he dived under, in order to seek out the treacherous channel in the half-light, he needed his fish's eyes and senses. He therefore would swim a few yards as a fish, but had to surface again as himself in order to let the men see him, and call: "The length of two boats, keeping to starboard, boys. Then ease her over this way—to port."

So it went, almost foot by foot until the Mirabelle was safe inside the cove and turned broadside to the entrance. Then, and only then, with the anchor safely dropped to the white sandy depths of this hidden harbor, did Chris, tired to his very bones, climb up the ladder and over the ship's side. There remained the camouflaging of the Mirabelle, for the stars were fading and before long, dawn would banish secrecy.

But Captain Blizzard and Mr. Finney awaited Chris on deck. Captain Blizzard had his hands clasped behind his back in his habitual gesture, and as Chris stood before him swaying with fatigue, there was a look on the Captain's face that Chris had never seen there before. The usually cheerful, joking man was grave, while Mr. Finney, so sober and forlorn as a rule, looked positively jubilant.

"My good lad," the Captain said, "you said you could do it, but truth to tell, I doubted it from the bottom of my heart. Now that you have succeeded where I am sure no other could have done as well, I find I have no words of praise good enough for ye." He looked almost tenderly at the tired boy. "I am proud of you, Christopher. You did a man's task with a boy's body and mind. And it took a man's spirit, too."

Without further words the Captain of the Mirabelle held out his pudgy hand to hold Chris's in a steadying grip, and Mr. Finney swung out his hand, his long face breaking into one of the rare smiles Chris was ever to see on it.

"Now, me boy," thundered the Captain, "do you go to your well-deserved rest. Depend upon it, we shall cover the ship with green until she looks like the proverbial Christmas hall decked with boughs of holly, as the song goes!" he added chuckling. "A little later in the day you shall be called to see what you make of the result. And now, to bed with ye both!" and he clapped Amos on the back.
