The woods were pretty full of the kind of hickory-trees called pignuts, and the boys gathered the nuts, and even ate their small, bitter kernels; and around the Poor-House woods there were some shag-barks, but the boys did not go for them because of the bull and the crazy people. Their great and constant reliance in foraging was the abundance of black walnuts which grew everywhere, along the roads and on the river-banks, as well as in the woods and the pastures. Long before it was time to go walnutting, the boys began knocking off the nuts and trying whether they were ripe enough; and just as soon as the kernels began to fill out, the fellows began making walnut wagons. I do not know why it was thought necessary to have a wagon to gather walnuts, but I know that it was, and that a boy had to make a new wagon every year. No boy's walnut wagon could last till the next year; it did very well if it lasted till the next day. He had to make it nearly all with his pocket-knife. He could use a saw to block the wheels out of a pine board, and he could use a hatchet to rough off the corners of the blocks, but he had to use his knife to give them any sort of roundness, and they were not very round then; they were apt to be oval in shape, and they always wabbled. He whittled the axles out with his knife, and he made the hubs with it. He could get a tongue ready-made if he used a broom-handle or a hoop-pole, but that had in either case to be whittled so it could be fastened to the wagon; he even bored the linchpin holes with his knife if he could not get a gimlet; and if he could not get an auger, he bored the holes through the wheels with a red-hot poker, and then whittled them large enough with his knife. He had to use pine for nearly everything, because any other wood was too hard to whittle; and then the pine was always splitting. It split in the axles when he was making the linchpin holes, and the wheels had to be kept on by linchpins that were tied in; the wheels themselves split, and had to be strengthened by slats nailed across the rifts. The wagon-bed was a candle-box nailed to the axles, and that kept the front-axle tight, so that it took the whole width of a street to turn a very little wagon in without upsetting.
