While the day presented much to occupy the attention, the night also afforded many objects of interest. The constellations of the northern hemisphere were now sinking one by one in the ocean; the Great Bear disappeared, followed by the Polar Star, and in their stead, towards the south, rose the Southern Cross, each night appearing higher and higher in the firmament. Charles and his sisters gazed at the beautiful constellation with deep interest. Beneath its glittering light they expected to pass the greatest portion of their future life; and it seemed to welcome them to the new world to which they were bound. Charles confessed that, interesting as it was, it scarcely equalled in beauty several of the northern constellations on which he had been accustomed to gaze. Now, too, the Magellanic clouds appeared in the heavens, composed probably of countless millions of worlds, so far away that the human mind can scarcely calculate their distance from this tiny world of ours. At night, also, Charles, with his sisters at his side, often watched the track of the ship on the ocean, which appeared like a broad road dotted with brilliant and innumerable stars; while on either side the waves were lighted up by thousands of electric sparks, appearing here and there; now lost altogether, now dispersed, as the waves rose and fell. Sometimes, when the wind freshened, and a huge sea broke against the bows with a tremendous crash, the spray appeared all alight, rising in the air to fall on deck like drops of fire. "Who would not wish to come to sea to witness such a spectacle as this?" exclaimed Emily, with enthusiasm, as the whole ocean appeared glowing with flashes of brilliant light. The remark was made not to Mrs Clagget, but to Mr Paget, who stood by her side. "You would scarcely suppose that this glorious illumination of the ocean is caused by countless numbers of minute living creatures," he observed. "As the telescope reveals to us some of the wonders of the heavens, so the microscope enables to inspect many of the smallest of created beings." "What, Mr Paget, is every spark of light we see a living creature?" asked May. "Yes, indeed," was the answer. "And probably we see at a time not a thousandth part of the number of those which are floating around."
