The morning passed over brightly and tranquilly, the sea was calm, the sky, with the exception of a few faint gray streaks scattered about it in different directions, was quite clear, the wind favourable, though not full, and nothing was seen over the face of the ocean, but a few scattering fishing boats, and the distant gleam of white sails making their way to various points upon the horizon. There was a quietness in the scene, a peaceful mildness in the aspect of the treacherous sea, which brought a calm to the bosom of Lucy Effingham and Charles Tyrrell. They felt as if the time which had passed before, had been a period of turmoil and vexation, of grief, care, and anguish, and as if now had begun another state, as if this was the first day of a tranquil existence. Toward three o'clock, however, not exactly to windward, but somewhat more to the southeast, the blue of the sky which had extended at first clear and distinct from the zenith to the horizon, began to change to a sort of lead colour, as it approached the verge of the sea. As the time went on, it grew deeper and deeper in hue, not separate, and defined from the rest of the sky, but blending into the blue as it approached the zenith, yet at the height of a few degrees above the waves presenting the colour of a dark cloud. Across this, too, there began to appear small detached masses of a cloud of a different colour, a whitish or silvery gray, and Hailes and the captain, who had passed the greater part of the day in walking up and down the deck, side by side, paused and looked out in that direction several times, commenting on what they saw with laconic briefness. Another object, however, soon after attracted their attention, which was a vessel right to windward, with all sails set, and coming up apparently with a much stronger breeze than they themselves possessed. The captain of the ship watched the coming vessel for a minute or two through his telescope, and then handed it to Hailes, who watched her accurately, also, for some time, and then replied to something that the master had said to him, "Yes, she is," and added a very unnecessary oath. The captain again took the glass, and after having resumed his examination for some time he turned round and gave orders for making more sail. These orders were promptly obeyed, and ere they had been executed long the wind began to freshen. The sea at the same time became somewhat rougher, and the schooner cut through the water with far greater rapidity. Charles Tyrrell began to be a little apprehensive, judging, from what he remarked, that the captain found greater reason to hurry his voyage, than he had at first anticipated. Leaving Lucy for a moment, he approached Hailes, and asked him in a low tone, what vessel that was they had been looking at. "She is the revenue-cutter," said Hailes; "at least I think so, by the cut of her sails." "Is there any chance of their coming up with us?" demanded Charles Tyrrell.
