“It does not seem at all difficult,” said the spirited little fellow; “put us each into a great tub, and let us float to shore. I remember sailing capitally that way on godpapa’s great pond at S—.”
“A very good idea, Jack; good counsel may sometimes be given even by a child. Be quick, boys, give me the saw and auger, with some nails, we will see what we can do.” I remembered seeing some empty casks in the hold. We went down and found them floating. This gave us less difficulty in getting them upon the lower deck, which was but just above the water. They were of strong wood, bound with iron hoops, and exactly suited my purpose; my sons and I therefore began to saw them through the middle. After long labour, we had eight tubs all the same height. We refreshed ourselves with wine and biscuit, which we had found in some 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.”
