`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 Archimedes' lever; from which he said he could move the world if he had a point from which his mechanism might operate, and promised to have a long talk on the subject of mechanics when we should be safe on land.

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, if the rope had not been well secured, 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 outriggers to preserve the balance, by nailing long poles across at the stem and stern, and fixing at the ends of each empty brandy cask.

Then, the boat appearing steady, I got in; and turning it towards 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. I persuaded my wife (not without considerable difficulty), to put on a sailor's dress, assuring her she would find it much more comfortable and convenient for all she would have to go through.

She at last consented to do this, and left us for a short time, reappearing with much embarrassment and many blushes, in a most becoming suit, which she had found in a midshipman's chest.* We all admired her costume, and any awkwardness she felt soon began to pass off; then we retired to our hammocks, where peaceful sleep prepared us all for the exertions of the coming day.
