"Do not be too sure of that, dear wife; when you see my contrivance completed, you will perhaps prefer it to this immovable wreck." I next procured a long, thin plank, on which my tubs could be fixed, and the two ends of this I bent upward so as to form a keel. Two other planks were nailed along the sides of the tubs; they also being flexible, were brought to a point at each end, and all firmly secured and nailed together. I felt satisfied that in smooth water this craft would be perfectly trustworthy. But when we thought all was ready for the launch, we found, to our dismay, that the grand contrivance was so heavy and clumsy, that even our united efforts could not move it an inch. "I must have a lever," cried I. "Run and fetch the capstan bar!" Fritz quickly brought one, and, having formed rollers by cutting up a long spar, I raised the forepart of my boat with the bar, and my sons placed a roller under it. "How is it, father," inquired Ernest, "that with that thing you alone can do more than all of us together?" I explained, as well as I could in a hurry, the principle of the lever; and promised to have a long talk on the subject of Mechanics, should we have a future opportunity. I now made fast a long rope to the stern of our boat, attaching the other end to a beam; then placing a second and third roller under it, we once more began to push, this time with success, and soon our gallant craft was safely launched: so swiftly indeed did she glide into the water that, but for the rope, she would have passed beyond our reach. The boys wished to jump in directly; but, alas, she leaned so much on one side that they could not venture to do so. Some heavy things being thrown in, however, the boat righted itself by degrees, and the boys were so delighted that they struggled which should first leap in to have the fun of sitting down in the tubs. But it was plain to me at once that something more was required to make her perfectly safe, so I contrived out-riggers to preserve the balance, by nailing long poles across at the stem and stern, and fixing at the ends of each empty brandy casks. Then the boat appearing steady, I got in; and turning it toward the most open side of the wreck, I cut and cleared away obstructions, so as to leave a free passage for our departure, and the boys brought oars to be ready for the voyage. This important undertaking we were forced to postpone until the next day, as it was by this time far too late to attempt it. It was not pleasant to have to spend another night in so precarious a situation; but yielding to necessity, we sat down to enjoy a comfortable supper, for during our exciting and incessant work all day we had taken nothing but an occasional biscuit and a little wine. We prepared for rest in a much happier frame of mind than on the preceding day, but I did not forget the possibility of a renewed storm, and therefore made every one put on the belts as before.
