Swiss Family Robinson

by Johann David Wyss

Jack showed me where he thought the bridge should be, and I certainly saw no better place, as the banks were at that point tolerably close to one another, steep, and of about equal height.

`How shall we find out if our planks are long enough to reach across?' said I. `A surveyor's table would be useful now.'

`What do you say to a ball of string, father?' said Ernest. `Tie one end to a stone, throw it across, then draw it back, and measure the line!'

Adopting my son's idea, we speedily ascertained the distance across to be eighteen feet. Then allowing three feet more at each side, I calculated twenty-four feet as the necessary length of the boards.

The question as to how the planks were to be laid across was a difficult one. We resolved to discuss it during dinner, to which we were now summoned. And my wife, as we sat resting, displayed to me her needlework. With hard labour had she made two large canvas bags for the ass to carry. Having no suitable needle, she had been obliged to bore the hole for each stitch with a nail, and gained great praise for her ingenuity and patience.

Dinner was quickly dispatched, as we were all eager to continue our engineering work. A scheme had occurred to me for conveying one end of a plank across the water, and I set about it in this way.

There fortunately were one or two trees close to the stream on either side; I attached a rope pretty near one end of a beam, and slung it loosely to the tree beside us; then, fastening a long rope to the other end, I crossed with it by means of broken rocks and stones, and having a pulley and block, I soon arranged the rope on a strong limb of the opposite tree, again returning with the end to our own side.

Now putting my idea to the proof, I brought the ass and the cow, and fastening this rope to the harness I had previously contrived for them, I drove them steadily away from the bank. To my great satisfaction, and the surprise and delight of the boys, the end of the plank which had been laid alongside the stream began gently to move, rose higher, turned, and soon projecting over the water continued to advance, until, having described the segment of a circle, it reached the opposite bank.

I stopped my team, the plank rested on the ground, the bridge was made! So at least thought Fritz and Jack, who in a moment were lightly running across the narrow way, shouting joyfully as they sprang to the other side.

Our work was now comparatively easy. A second and third plank were laid beside the first; and when these were carefully secured at each end to the ground and to the trees, we very quickly laid short boards side by side across the beams, the boys nailing them lightly down as I sawed them in lengths; and when this was done, our bridge was pronounced complete.
