of the casks. I then contemplated with delight my little squadron of boats ranged in a line; and was surprised that my wife still continued depressed. She looked mournfully on them. "I can never venture in one of these tubs," said she.
"Wait a little, till my work is finished," replied I, "and you will see it is more to be depended on than this broken vessel."
I sought out a long flexible plank, and arranged eight tubs on it, close to each other, leaving a piece at each end to form a curve upwards, like the keel of a vessel. We then nailed them firmly to the plank, and to each other. We nailed a plank at each side, of the same length as the first, and succeeded in producing a sort of boat, divided into eight compartments, in which it did not appear difficult to make a short voyage, over a calm sea.
But, unluckily, our wonderful vessel proved so heavy, that our united efforts could not move it an inch. I sent Fritz to bring me the jack-screw, and, in the mean time, sawed a thick round pole into pieces; then raising the fore-part of our work by means of the powerful machine, Fritz placed one of these rollers under it.
Ernest was very anxious to know how this small machine could accomplish more than our united strength. I explained to him, as well as I could, the power of the lever of Archimedes, with which he had declared he could move the world, if he had but a point to rest it on; and I promised my son to take the machine to pieces when we were on shore, and explain the mode of operation. I then told them that God, to compensate for the weakness of man, had bestowed on him reason, invention, and skill in workmanship. The result of these had produced a science which, under the name of Mechanics, taught us to increase and extend our limited powers incredibly by the aid of instruments.
Jack remarked that the jack-screw worked very slowly.
"Better slowly, than not at all," said I. "It is a principle in mechanics, that what is gained in time is lost in power. The jack is not meant to work rapidly, but to raise heavy weights; and the heavier the weight, the slower the operation. But, can you tell me how we can make up for this slowness?"
"Oh, by turning the handle quicker, to be sure!"
"Quite wrong; that would not aid us at all. Patience and Reason are the two fairies, by whose potent help I hope to get our boat afloat."
I quickly proceeded to tie a strong cord to the after-part of it, and the other end to a beam in the ship, which was still firm, leaving it long enough for security; then introducing two more rollers underneath, and working with the jack, we succeeded in launching our bark, which passed into the water with such velocity, that but for our rope it would have gone out to sea. Unfortunately, it leaned so much on one side, that none of the boys would venture into it. I was in despair, when I suddenly remembered it only wanted ballast to keep it in equilibrium. I hastily threw in anything I got hold of that was heavy, and soon had my boat level, and ready for occupation. They now contended who should enter first; but I stopped them, reflecting that these restless children might easily capsize our vessel. I remembered that savage nations made use of an out-rigger, to prevent their canoe oversetting, and this I determined to add to my work. I fixed two portions of a topsail-yard, one over the prow, the other across the stern, in such a manner that they should not be in the way in pushing off our boat from the wreck. I forced the end of each yard into the bunghole of an empty brandy-cask, to keep them steady during our progress.
It was now necessary to clear the way for our departure. I got into the first tub, and managed to get the boat into the cleft in the ship's side, by way of a haven; I then returned, and, with the axe and saw, cut away right and left all that could obstruct our passage. Then we secured some oars, to be ready for our voyage next day.
The day had passed in toil, and we were compelled to spend another night on the wreck, though we knew it might not remain till morning. We took a regular meal, for during the day we had scarcely had time to snatch a morsel of bread and a glass of wine. More composed than on the preceding night, we retired to rest. I took the precaution to fasten the swimming apparatus
