The ships' bells were chiming "five", that is to say, half-past ten, as the boat, after having been challenged by the anchor watch, swept alongside the _Thetis's_ gangway ladder, and the two young men ascended to the deck. Somewhat to their surprise, they found Milsom on board; for, as they were not expected until the following day, they would not have been at all astonished to learn that the skipper was ashore, amusing himself at the theatre, or elsewhere. But Milsom explained that he had had enough of Havana: he had been to the theatre twice, and considered that it was not a patch upon the Alhambra in Leicester Square at home; he had been to the Cathedral, and had been shown the tomb of Christopher Columbus--the genuineness of which he greatly doubted; he had sauntered in the Alameda in the evenings, listening to the military bands, of which he thought nothing, and trying to discover a Spanish girl that could hold a candle to one of our own wholesome, handsome English lasses, and had failed; and he had also tried, and had failed, to determine the precise number of separate and distinct odours--"stinks", he called them--which go to make up the characteristic smell of Havana. From all of which it will be gathered that the worthy man, with the restlessness characteristic of the sailor, was beginning to weary of his inactivity--although during the past week he had been anything but inactive, it may be mentioned--and was pining for something fresh in the way of excitement. It appeared that, finding himself with spare time on his hands notwithstanding his preparation of the yacht for the projected trip, he had amused himself by designing an elaborate disguise for the craft, under the impression that a time might very possibly arrive when such a disguise would be found exceedingly useful; and he proudly produced a sketch of the said disguise which, when unfolded before the astonished gaze of the two young men, showed the _Thetis_ transmogrified into something resembling a two-funnelled torpedo gunboat, with ram stem and round, spoon-shaped stern all complete. It was a contraption most ingeniously built up of wood and canvas by the joint efforts and skill of Milsom, Macintyre, and the carpenter; and was so handily contrived that, according to the statement of its inventor or designer, given fine weather and smooth water for four hours, the vessel's appearance could be so completely changed that "her own mother wouldn't know her."
