I was already some way up the hill before I paused to breathe and look behind me. The sight that met my eyes was doubly strange.

For, first, the storm that I had foreseen was now advancing with almost tropical rapidity. The whole surface of the sea had been dulled from its conspicuous brightness to an ugly hue of corrugated lead; already in the distance the white waves, the 'skipper's daughters,' had begun to flee before a breeze that was still insensible on Aros; and already along the curve of Sandag Bay there was a splashing run of sea that I could hear from where I stood. The change upon the sky was even more remarkable. There had begun to arise out of the south-west a huge and solid continent of scowling cloud; here and there, through rents in its contexture, the sun still poured a sheaf of spreading rays; and here and there, from all its edges, vast inky streamers lay forth along the yet unclouded sky. The menace was express and imminent. Even as I gazed, the sun was blotted out. At any moment the tempest might fall upon Aros in its might.

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.
