The cruiser was the next craft to be dealt with, and, after her, the gunboat; the whole operation of disabling the three vessels being accomplished with almost ludicrous ease in about an hour and a quarter: after which the adventurers returned to the yacht and hoisted in the submarine, stowing her away and concealing her in the quarter boat, without, so far as they were aware, having attracted the attention of a single soul. CHAPTER TEN. THE ACT OF "CERTAIN VERY CLEVER CONSPIRATORS." When, on the following morning, the saloon party on board the _Thetis_ mustered for breakfast beneath the awning which sheltered the top of the deck-house from the too-ardent rays of the sun, they found that their alfresco breakfast-room commanded an uninterrupted and most charming view of the whole of Havana harbour, with the picturesque old town stretching along the waterside on their port hand. It was at that moment a dead calm, for the sea breeze had not yet set in, and the mirrorlike surface of the water reflected a perfect picture of the various craft dotted about the harbour, and of the buildings ashore, already blazing in the dazzling light of the unclouded sun. The business of the day had hardly begun; the ferryboats to Regla were loaded with passengers; boats conveying meat, vegetables, fruit, and fish to the shipping were lazily rippling through the scum that coated the surface of the water; belated fishermen were sweeping their crazy- looking craft out to sea; and a thin column of brown smoke was rising vertically into the motionless air from the funnel of torpedo boat Number 19, which was evidently getting up steam in good time to go in search of the _James B. Potter_. But for the awning over their heads the party would also have seen that a thin, feathery film of smoke was curling upward from the cream-coloured funnel of their own craft; for although it had been decided not to go to sea until the afternoon, Jack had given instructions to have steam for ten o'clock, so as to be prepared for any emergency.
