Then another sound—a dull _flop! flop!_—in the distance; and the stragglers who have remained below after luncheon are hastily summoned on deck. And there, far away in the haze, we can dimly descry the successive curved forms of a school of dolphins, racing each other, and springing twenty or thirty feet in the air before they come down with that heavy thud on the water. Those of us who have watched the beautiful lithe fish racing and chasing by the side of an Atlantic vessel, would fain have been somewhat nearer; but we can only see the dim forms springing into the haze. Then the dull pistol-shots in the south slowly cease, and we are left alone on the low murmuring sea. "But where is Miss Mary?" says the Laird, suddenly becoming aware of the absence of his chief companion. "Oh, she is in the saloon!" says his hostess, quickly and anxiously. "She is doing something to one of her water-colours. I suppose we must not disturb her." "No, no; certainly not," returns the Laird, lightly; and then he adds, with a smile which is meant to be very significant, "There is never any harm in hard work. Let her go on; she will have a fine collection of sketches before she leaves the _White Dove_." But our Queen Tita does not respond to that careless joke. There is a curious, constrained look on her face; and she quite peremptorily negatives a suggestion of the Youth that he should go below for the draught-board. Then one of us perceives that Angus Sutherland is not on deck. Has the opportunity come at last, then, for the clearing away of all secret troubles? What end is there to be to this momentous interview? Is it Stornoway harbour? Is our frank-eyed young Doctor to come up with a silent wonder and joy on his face—a message that needs no speech—a message that only says, "About with the yacht, and let us run away to the northern seas and Stornoway?" The friend of these two young people can hardly conceal her anxiety. She has got hold of the case of an opera glass, and opens and shuts it quickly and aimlessly. Then there is a step on the companion way; she does not look; she only knows that Angus Sutherland comes on deck, and then goes forward to the bow of the gig, and stands by himself, and looks out to sea. There is silence on board; for a low rumble of thunder has been heard once or twice, and we are listening. The mountains of Jura are dark now, and the sultry mist in the south is deeper in its gloom. This condition of the atmosphere produces a vague sense of something about to happen, which is in itself uncomfortable; one would almost like to see a flash of lightning, or hear the thunderous advance of a storm breaking in upon the oppressive calm. The Laird goes forward to Angus Sutherland. "Well, Doctor, and what think ye of the weather now?" The younger man starts and turns round, and for a second looks at the Laird as if he had not quite comprehended the question.
