“We are now under the cloud ring which encircles this part of the earth. God has placed these clouds above our heads in this region for a particular purpose. You will observe that the thermometer and barometer stand lower under this cloud ring than they do on either side of it. The clouds not only promote the precipitation which takes place in this region, but they also cause the rains to fall on places where they are most required, shading the surface from which the heating rays of the sun are to be excluded, and thus giving tone to the atmospherical circulation of the world and vigour to its vegetation. You have often, when the sun is sending his rays with great heat down on the earth, seen the atmosphere dancing, as it were, and trembling. This appearance is caused by the ascending and descending columns of air. The cloud ring creates on a greater scale this circulation of the atmosphere; indeed, the more we examine the phenomena of Nature, the more we shall discover the hand of a directing Providence, in suiting all things for the convenience and use of the beings placed by Him on the earth.”

Day after day the ship remained in this calm region with a cloudy sky. People began to feel ill; and some fancied that as they were going further south the heat would increase, and could scarcely understand that as they proceeded the atmosphere would again become cold. Captain Davenport and the officers were on the watch to make use of every breath of air which would forward the ship on her course; and at length she once more got the breeze, and those who had before been complaining of lassitude and illness suddenly revived and came on deck to enjoy the renovating and refreshing breeze. The sky was clear; the sea bright and sparkling as before. Cheerful countenances were everywhere visible, instead of the weary, downcast looks which most of those on board had worn for the previous ten days. The only person who never seemed depressed was Mr Hooker. When not taking exercise on deck, he always had a volume in his hand, from which he was constantly making notes into his pocket-book.

“You see, my young friend,” he said to me one day, “I am anxious to ascertain what others have known, because all that man can aim at is to increase the stock of knowledge possessed by his fellow-men.”

The varied changes of the ocean, and the creatures which appeared beneath its surface, and occasionally above it, afforded us an unfailing source of interest. On a bright morning I was engaged with some work by the side of the boatswain when I heard Grace cry out—

“Oh, look—look what funny birds!”

“Why, miss, those are not birds, unless they may be called water birds; those are flying-fish,” said Mr Tarbox, who had come with me to the ship’s side.

Others, with Mr Hooker, came also, looking on at the curious sight. Numbers of fish with wings, or more properly fins, as long as their bodies, were rising out of the water and darting along for a considerable distance above the surface, again, however, to fall helplessly into their native element. Directly after them, in pursuit, appeared several large fish—now one of the latter leaped half out of the water, now another, seldom failing to catch one of the beautiful creatures in its huge jaws.

“The dolphins are getting a fine banquet,” I heard Mr Hooker remark. “The poor dactylopteri are the sufferers; but they do not fall a prey to their persecutors without a brave attempt to escape. See, no sooner have they wetted their wings than they are out of the water again, and will lead them a long chase, till the dolphins are wearied out.”

We watched the pursuers and pursued till they were lost to sight in the distance.

The ship once clear of the Doldrums, met the steady trade-wind blowing from the south-east. With her tacks aboard, she stood away towards the South American coast. When I went on deck at night, I observed a change in the appearance of the constellations; and now the beautiful one of the Southern Cross became every day clearer, rising as it were in the sky. The magellhenic clouds also came in sight, showing that the ship was now in the southern hemisphere. Frequently patches of light were passed in the water; caused, Mr Hooker told me, by the pyrosoma. They exhibited a beautiful pale silvery light; but when they were taken out of the water the light disappeared, till any particular part of the creature was touched, when the light again burst forth at that point, pervading the whole animal mass.
