“By all means,” answered Jack cordially. “Pray send your boat for your lieutenant—and any other officers whom you would like to be present. The more, the better; for, Señor, you must understand that I wish your inspection of my yacht to be thorough and exhaustive.”

The Spaniard bowed and, stepping to the gangway, called down to his coxswain, instructing him to proceed to the gunboat and request Lieutenant Fernandez to come on board the English yacht forthwith. Then, during the short interval between the dispatch and the return of the boat, the Spanish Commander chatted affably with Jack and Milsom upon indifferent subjects, incidentally introducing himself as Commander Luis y Albuquerque.

Lieutenant Fernandez was in a much more subdued mood when he returned than he had been upon his departure from the Thetis: probably he had done some hard thinking in the interim, and had come to recognise the possibility that trouble might be looming ahead of him; at all events his manner was all courtesy and politeness as he again stepped in through the gangway.

“Señor Fernandez,” said Don Luis, “I am very much afraid that, from what Don Juan Singleton has told me, there has been a most serious mistake somewhere, and that we have thus been betrayed into unwittingly inflicting a most unprovoked affront upon an English gentleman. Señor Singleton has, however,” with a bow to Jack, “been good enough to accept my explanation and apologies, and I therefore venture to hope that we may now consider the incident as closed. But Señor Singleton insists—quite justifiably, I think—that we shall satisfy ourselves as to the falsity of the statement that he is carrying munitions of war; and I have therefore sent for you to accompany me on a tour of inspection through this yacht, which we must make so thorough that there shall be no possibility of any aspersions being hereafter cast upon the integrity of Don Juan or his vessel. And now, Señor,” to Jack, “we are ready to accompany you.”

“Very well,” said Jack. “Where would you like to begin—forward, or aft?”

“Perhaps we may as well begin forward, and work our way aft,” answered the Spanish Commander.

“Right,” acquiesced Jack. “Captain Milsom, be so good as to give instructions for two or three men to attend us below with lanterns. Meanwhile, gentlemen, perhaps you will give my boats an overhaul. I will have the canvas covers stripped off them.”

“Oh no, Señor,” protested Don Luis, “there is not the slightest necessity for us to go to such extreme lengths as that; for, assuming for a moment that you actually had contraband on board, you would not be in the least likely to carry it stowed in your boats.”

Now this offer of Jack’s was a piece of “bluff”, for his boats were the only places that he did not wish the Spaniards to examine, since in one of them was stowed his submarine, the sight of which he knew would be likely to give rise to renewed suspicions. And, as we have seen, the “bluff” worked to perfection, possibly in consequence of the slight, but none the less perceptible, tone of sarcasm in which Jack made the offer. With a feeling of carefully suppressed relief, Jack accordingly led the Spaniards forward to the forecastle, down into which the party descended, and where they found three men—one of whom was the carpenter—awaiting them with lighted lanterns. The forecastle was soon examined, and then the hatch of the forepeak was lifted, and that darksome storehouse very carefully explored. There was no passage from the forepeak into the hold, as the collision bulkhead ran from the keelson right up to the deck; and, Jack having pointed out this fact, the party emerged on deck and descended into the officers’ quarters, proceeding from thence down into the main hold, where they found nothing but iron ballast and the water tanks, every one of which Jack insisted should be opened and looked into. Thence they proceeded to the engine-room and stokehold, where they found much to admire in the scrupulous cleanliness and unusual form of the machinery, but no sign or trace of anything in the nature of contraband. Then they entered the main saloon, and examined it and the sleeping cabins, finishing up with the steward’s storeroom, the sail-room, and the powder magazine. Jack was quite prepared to be questioned about this last, and he was; but he had his answer ready.

“Is it usual, Señor Singleton, for English yachts to go as heavily armed as your vessel is?” suavely enquired Don Luis.
