The first of these inventions was a simple one, but it made necessary all that followed. From the beginning of the art, one man could weave into cloth all the yarn that several spinners could produce. Indeed, it was seldom that a weaver’s family, his wife and children all working at the spinning wheel, could supply sufficient weft for his loom; and this difficulty was increased by the invention of the fly-shuttle in the year 1738. This invention, made by John Kay, consisted in giving motion to the shuttle by a mechanical device which saved time and exertion to the weaver and nearly doubled the daily product of his loom. The increased demand for yarn led to many experiments, and at last a machine was produced upon which many threads could be spun by a single pair of hands: the water frame commonly attributed to Richard Arkwright. With this important invention came many others in the same field, making famous the names of Hargreaves, Crompton, and Cartwright. The moment it became possible to accomplish by machinery what formerly had been done entirely by hand, the first effect was to increase the productive power of the workman and thus to add vastly to the wealth of the nation, and secondly, to gather into the factories the craftsmen who had formerly worked in their homes. In the beginning of the eighteenth century the textile manufacturing of England was carried on by craftsmen dwelling in the rural districts, the master clothiers living in the greater towns, sending out wool to be spun into yarn which, returned to them prepared for the loom, was re-distributed among other hand workers in other cottages. The Lancashire weaver worked in his cottage surrounded by a bit of land, and generally combined small farming with domestic manufacturing. Sometimes a single family performed all the labor, the wife and daughters working at carding and spinning, the father operating the loom; sometimes other craftsmen joined the household and worked as members of one family. The extent of mercantile establishments and the modes of doing business were very different from what they were soon to become. It is quite true that a limited number of individuals had, in previous ages, made fortunes by trade, but until the very end of the seventeenth century the capital in the hands of British merchants was small. Because of the bad condition of the roads and the lack of inland navigation, goods were conveyed by pack horses with which the Manchester chapmen traveled through the principal towns, selling their goods to the shopkeepers, or at the public fairs, and bringing back sheep’s wool to be sold to the clothiers of the manufacturing districts.
