Lydia did not know when the captain came on board. Once, talking in the cabin made itself felt through her dreams, but the dense sleep of weary youth closed over her again, and she did not fairly wake till morning. Then she thought she heard the crowing of a cock and the cackle of hens, and fancied herself in her room at home; the illusion passed with a pang. The ship was moving, with a tug at her side, the violent respirations of which were mingled with the sound of the swift rush of the vessels through the water, the noise of feet on the deck, and of orders hoarsely shouted. The girl came out into the cabin, where Thomas was already busy with the breakfast table, and climbed to the deck. It was four o'clock of the summer's morning; the sun had not yet reddened the east, but the stars were extinct, or glimmered faint points immeasurably withdrawn in the vast gray of the sky. At that hour there is a hovering dimness over all, but the light on things near at hand is wonderfully keen and clear, and the air has an intense yet delicate freshness that seems to breathe from the remotest spaces of the universe,--a waft from distances beyond the sun. On the land the leaves and grass are soaked with dew; the densely interwoven songs of the birds are like a fabric that you might see and touch. But here, save for the immediate noises on the ship, which had already left her anchorage far behind, the shouting of the tug's escape-pipes, and the huge, swirling gushes from her powerful wheel, a sort of spectacular silence prevailed, and the sounds were like a part of this silence. Here and there a small fishing schooner came lagging slowly in, as if belated, with scarce wind enough to fill her sails; now and then they met a steamboat, towering white and high, a many-latticed bulk, with no one to be seen on board but the pilot at his wheel, and a few sleepy passengers on the forward promenade. The city, so beautiful and stately from the bay, was dropping, and sinking away behind. They passed green islands, some of which were fortified: the black guns looked out over the neatly shaven glacis; the sentinel paced the rampart.
