When Bedford had read this passage, John Fordyce said he had travelled hundreds of miles on the Western railways where Mr. Edgeworth's sails could have been applied without a "stage-coach" to be afraid of them.
JACK THE DARTER.
In one of my journeys from Hare Hatch to Birmingham, I accidentally met with a person whom I, as a mechanic, had a curiosity to see. This was a sailor, who had amused London with a singular exhibition of dexterity. He was called Jack the Darter. He threw his darts, which consisted of thin rods of deal of about half an inch in diameter and of a yard long, to an amazing height and distance; for instance, he threw them over what was then called the New Church in the Strand. Of this feat I had heard, but I entertained some doubts upon the subject. I had inquired from my friends where this man could be found, but had not been able to discover him. As I was driving towards Birmingham in an open carriage of a singular construction, I overtook a man who walked remarkably fast, but who stopped as I passed him, and eyed my equipage with uncommon curiosity. There was something in his manner that made me speak to him; and from the sort of questions he asked about my carriage, I found that he was a clever fellow. I soon learned that he had walked over the greatest part of England, and that he was perfectly acquainted with London. It came into my head to inquire whether he had ever seen the exhibition about which I was so desirous to be informed.
"Lord! sir," said he, "I am myself Jack the Darter." He had a roll of brown paper in his hand, which he unfolded, and soon produced a bundle of the light deal sticks which he had the power of darting to such a distance. He readily consented to gratify my curiosity; and after he had thrown some of them to a prodigious height, I asked him to throw some of them horizontally. At the first trial he threw one of them eighty yards with great ease. I observed that he coiled a small string round the stick, by which he gave it a rotary motion that preserved it from altering its course; and at the same time it allowed the arm which threw it time to exercise its whole force.
If anything be simply thrown from the hand, it is clear that it can acquire no greater velocity than that of the hand that throws it; but if the body that is thrown passes through a greater space than the hand, whilst the hand continues to communicate motion to the body to be impelled, the body will acquire a velocity nearly double to that of the hand which throws it. The ancients were aware of this; and they wrapped a thong of leather round their javelins, by which they could throw them with additional violence. This invention did not, I believe, belong to the Greeks; nor do I remember its being mentioned by Homer or Xenophon. It was in use among the Romans, but at what time it was introduced or laid aside I know not. Whoever is acquainted with the science of projectiles will perceive that this invention is well worthy of their attention.
A ONE-WHEELED CHAISE.
After having satisfied my curiosity about Jack the Darter, I proceeded to Birmingham. I mentioned that I travelled in a carriage of a singular construction. It was a one-wheeled chaise, which I had had made for the purpose of going conveniently in narrow roads. It was made fast by shafts to the horse's sides, and was furnished with two weights or counterpoises, that hung below the shafts. The seat was not more than eight and twenty or thirty inches from the ground, in order to bring the centre of gravity of the whole as low as possible. The footboard turned upon hinges fastened to the shafts, so that when it met with any obstacle it gave way, and my legs were warned to lift themselves up. In going through water my legs were secured by leathers, which folded up like the sides of bellows; by this means I was pretty safe from wet. On my road to Birmingham I passed through Long Compton, in Warwickshire, on a Sunday. The people were returning from church, and numbers stopped to gaze at me. There is, or was, a shallow ford near the town, over which there was a very narrow bridge for horse and foot passengers, but not sufficiently wide for wagons or chaises. Towards this bridge I drove. The people, not perceiving the structure of my one-wheeled vehicle, called to me with great eagerness to warn me that the bridge was too narrow for carriages. I had an excellent horse, which went so fast as to give but little time for examination. The louder they called, the faster I drove; and when I had passed the bridge, they shouted after me with surprise. I got on to Shipstone upon Stone; but before I had dined there I found that my fame had overtaken me. My carriage was put into a coach-house, so that those who came from Long Compton, not seeing it, did not recognize me. I therefore had an opportunity of hearing all the exaggerations and strange conjectures which were made by those who related my passage over the narrow bridge. There were posts on the bridge, to prevent, as I suppose, more than one horseman from passing at once. Some of the spectators asserted that my carriage had gone over these posts; others said that it had not wheels, which was indeed literally true; but they meant to say that it was without any wheel. Some were sure that no carriage ever went so fast; and all agreed that at the end of the bridge, where the floods had laid the road for some way under water, my carriage swam on the surface of the water.
