“Ah!” remarked Don Hermoso; “I will see that Don Sebastian’s visits are discouraged henceforth. It is true that I know nothing against him—indeed, he is spoken of as a very promising officer—still, like yourself, Carlos, I do not altogether trust him; he is not precisely a desirable acquaintance, and I will endeavour to make him understand that he is not wanted at the hacienda.”

At this moment the Thetis passed Cape Frances and opened out into the Bay of Cortes.

“There is our destination, gentlemen,” said Milsom, pointing to a projecting bluff some eight or nine miles up the coast. “That bluff is Piedras Point; and beyond it is the Laguna de Cortes—or the Pirates’ Lagoon as some people call it. And here we are at the edge of the Bank; from this point onward I intend to proceed very cautiously indeed.”

So saying, he laid his hand upon the handle of the engine-room telegraph and rang down for “Half speed”, calling down the voice tube a moment later for the engines to be run dead slow. And as the yacht slowed up she passed from the dark blue of the deep water to the pale, whitish blue of the shallow water that covers the immense coral reef known locally as The Bank.

“Mr Perkins,” shouted Milsom, “I must have a man as lookout at the foremast-head, if you please. You had better bend a boatswain’s chair on to the gaff-topsail halyards, and send him up in that, as I shall require him to stay there until we are safely at anchor. And when you have done that, rouse your cable on deck, and see everything ready for letting go. Jack, I can spare eyes for nothing but the ship just now, so oblige me, will you, by taking the glasses, and say whether you can see anything in the shape of a boat coming toward us with a flag flying. And, between whiles, you may just look carefully along the coast to see if you can spot a guarda-costa hovering about. We don’t want to be caught napping in the act of landing this stuff.”

Jack took the glasses out of their case and swept the whole of the visible coast, but for some time without result; there was nothing under either sail or steam to be seen in any direction. At length, however, when the yacht had arrived within about two miles of Piedras Point, a small pirogue under sail suddenly shot out from behind the point, heading to the southward close-hauled; she carried a sprit-mainsail and a jib, and at the top end of the sprit there fluttered a diminutive replica of the red-and-yellow flag which was flying from the fore truck of the yacht.

“Ah!” exclaimed Jack, as he brought his glasses to bear upon the boat; “here comes your pilot, Phil, at last, and he is flying the ‘all right’ signal, so I suppose we may take it for granted that the coast is clear.”

“Yes, I see him,” answered Milsom. “Keep her away a couple of points, Quartermaster, and give that boat a chance to fetch us. She is coming alongside. Masthead there. Keep a very bright lookout, my man, for sunken rocks; there are plenty of them to be found here if they are looked for.”

“Ay, ay, sir!” answered the man. “We have passed a few already; but I didn’t say anything, because we weren’t headin’ so as to hit ’em.”

Ten minutes later the pirogue was close at hand, and Milsom rang down the signal to “Stop”. The pirogue was a very quaint-looking craft, of about twenty feet in length by some five feet beam, formed out of a solid log of wood which had been roughly trimmed with an axe to form the bottom portion of her, with a couple of planks above to form her top sides. Although the trade wind was blowing quite fresh, this queer-looking craft carried no ballast, properly so-called; but to prevent her from capsizing a couple of negroes stood on her weather gunwale, holding on to ropes attached to her masthead, and leaning back almost horizontally out over the water. A third negro, attired in a picturesquely dirty shirt, and trousers rolled up above his knees, and with a most shockingly dilapidated straw hat on his head, steered the little craft by means of a broad-bladed paddle laid out over the lee quarter. Primitive, however, as the craft was in appearance, she came through the water at a most astonishing rate, and presently shot up alongside under the lee of the yacht, the two negroes who acted as ballast smartly recovering themselves and springing inboard as she did so. A rope’s end was thrown down into her, and the picturesque individual who had been steering her nimbly climbed up the side of the yacht and stepped on deck, where he was met by Don Hermoso.
