"In the year 1780, there were twenty Water Frame factories, the property of Mr. Arkwright, or of persons who had paid him a consideration for permission to use his machines. After the repeal of the patent in 1785, the number of factories rapidly increased, and in 1790, there were one hundred and fifty in England and Wales. About 1790, factories were also built for the Jenny; in these factories the cotton was carded and roved by the newly -invented machines, which furnished weft better in quality and lower in price, than that spun on the smaller Jennies in the houses of the weavers. Carding, roving and spinning were now given up in the cottages, and the women and children formerly employed in those operations, applied themselves to the Loom. The invention of the Mule, by enabling spinners to make finer yarns than any the Jenny and Water Frame could produce, gave birth to the muslin manufacture, and found employment for this additional number of weavers."
