The suddenness of this change of weather so fixed my eyes on heaven that it was some seconds before they alighted on the bay, mapped out below my feet, and robbed a moment later of the sun. The knoll which I had just surmounted overflanked a little amphitheatre of lower hillocks sloping towards the sea, and beyond that the yellow arc of beach and the whole extent of Sandag Bay. It was a scene on which I had often looked down, but where I had never before beheld a human figure. I had but just turned my back upon it and left it empty, and my wonder may be fancied when I saw a boat and several men in that deserted spot. The boat was lying by the rocks. A pair of fellows, bareheaded, with their sleeves rolled up, and one with a boathook, kept her with difficulty to her moorings for the current was growing brisker every moment. A little way off upon the ledge two men in black clothes, whom I judged to be superior in rank, laid their heads together over some task which at first I did not understand, but a second after I had made it out - they were taking bearings with the compass; and just then I saw one of them unroll a sheet of paper and lay his finger down, as though identifying features in a map. Meanwhile a third was walking to and fro, polling among the rocks and peering over the edge into the water. While I was still watching them with the stupefaction of surprise, my mind hardly yet able to work on what my eyes reported, this third person suddenly stooped and summoned his companions with a cry so loud that it reached my ears upon the hill. The others ran to him, even dropping the compass in their hurry, and I could see the bone and the shoe-buckle going from hand to hand, causing the most unusual gesticulations of surprise and interest. Just then I could hear the seamen crying from the boat, and saw them point westward to that cloud continent which was ever the more rapidly unfurling its blackness over heaven. The others seemed to consult; but the danger was too pressing to be braved, and they bundled into the boat carrying my relies with them, and set forth out of the bay with all speed of oars.
I made no more ado about the matter, but turned and ran for the house. Whoever these men were, it was fit my uncle should be instantly informed. It was not then altogether too late in the day for a descent of the Jacobites; and may be Prince Charlie, whom I knew my uncle to detest, was one of the three superiors whom I had seen upon the rock. Yet as I ran, leaping from rock to rock, and turned the matter loosely in my mind, this theory grew ever the longer the less welcome to my reason. The compass, the map, the interest awakened by the buckle, and the conduct of that one among the strangers who had looked so often below him in the water, all seemed to point to a different explanation of their presence on that outlying, obscure islet of the western sea. The Madrid historian, the search instituted by Dr. Robertson, the bearded stranger with the rings, my own fruitless search that very morning in the deep water of Sandag Bay, ran together, piece by piece, in my memory, and I made sure that these strangers must be Spaniards in quest of ancient treasure and the lost ship of the Armada. But the people living in outlying islands, such as Aros, are answerable for their own security; there is none near by to protect or even to help them; and the presence in such a spot of a crew of foreign adventurers - poor, greedy, and most likely lawless - filled me with apprehensions for my uncle's money, and even for the safety of his daughter. I was still wondering how we were to get rid of them when I came, all breathless, to the top of Aros. The whole world was shadowed over; only in the extreme east, on a hill of the mainland, one last gleam of sunshine lingered like a jewel; rain had begun to fall, not heavily, but in great drops; the sea was rising with each moment, and already a band of white encircled Aros and the nearer coasts of Grisapol. The boat was still pulling seaward, but I now became aware of what had been hidden from me lower down - a large, heavily sparred, handsome schooner, lying to at the south end of Aros.
