Little fellows, especially of the class of brick-layers, are no great readers, otherwise we might suspect that the feat of the skipper-boys had conveyed some inspiration to Steeple Jack. Who is Steeple Jack? asks some innocent reader at the Antipodes. He is a little, spare creature who flies his kite over steeples when there is any thing to do to them, and lodging a cord on the apex, contrives by its means to reach the top without the trouble of scaffolding. No fragility, no displacement of stones, no leaning from the perpendicular, frightens Steeple Jack. He is as bold as his namesake, Jack-the-Giant-Killer, and does as wonderful things. At Dunfermline, not long ago, when the top of the spire was in so crazy a state that the people in the street gave it a wide berth as they passed, he swung himself up without hesitation, and set every thing to rights. At the moment we write, his cord is seen stretched from the tall, slim, and elegant spire of the Assembly Hall in Edinburgh, which is to receive, through his agency, a lightning-conductor; and Jack only waits the subsidence of a gale of wind to glide up that filmy rope like a spider. He is altogether a strange boy, Steeple Jack. Nobody knows where he roosts upon the earth, if he roosts any where at all. The last time there was occasion for his services, this advertisement appeared in the _Scotsman_: “Steeple Jack is wanted at such a place immediately”—and immediately Steeple Jack became visible. In 1827 the child’s toy was put to a very remarkable use by one Master George Pocock. This clever little fellow observed that his kite sometimes gave him a very strong pull, and it occurred to him that if made large enough it might be able to pull something else. In fact, he at length yoked a pair of large kites to a carriage, and traveled in it from Bristol to London, distancing in grand style every other conveyance on the road. A twelve-foot kite, it appears, in a moderate breeze, has a one-man power of draught, and when the wind is brisker, a force equal to 200 lbs. The force in a rather high wind is as the squares of the lengths; and two kites of fifteen and twelve feet respectively, fastened one above the other will draw a carriage and four or five passengers at the rate of twenty miles an hour. But George’s invention went beyond the simple idea. He had an extra line which enabled him to vary the angle of the surface of his kites with the horizon, so as to make his aerial horses go fast or slow as he chose; and side lines to vary the direction of the force, till it came almost to right angles with the direction of the wind. His kites were made of varnished linen, and might be folded up into small compass. The same principle was successfully applied by a nautical lad of the name of Dansey to the purpose of saving vessels in a gale of wind on “the dread lee shore.” His kite was of light canvas.
