dyeing, if that had not been done earlier, and others, according to the nature of the cloth or the kind of surface desired. In these successive stages of manufacture it was the spinning that was apt to interpose the greatest obstacle, as it took the most time. From time immemorial spinning had been done, as explained, on some form of the spinning-wheel, and by women. One weaver continuously at work could easily use up the product of five or six spinners. In the domestic industry the weaving was of course carried on in the dwelling-house by the father of the family with the grown sons or journeymen, while the spinning was done for the most part by the women and younger children of the family. As it could hardly be expected that there would always be as large a proportion as six of the latter class to one of the former, outside help must be obtained and much delay often submitted to. Many a small master who had agreed to weave up the raw material sent him by the master clothier within a given time, or a cloth weaver who had planned to complete a piece by next market day, was obliged to leave his loom and search through the neighborhood for some disengaged laborer's wife or other person who would spin the weft for which he was waiting. One of the very few inventions of the early part of the century intensified this difficulty. Kay's drop box and flying shuttle, invented in 1738, made it possible for a man to sit still and by pulling two cords alternately throw the shuttle to and fro. One man could therefore weave broadcloth instead of its requiring two as before, and consequently weaving was more rapid, while no corresponding change had been introduced into the process of spinning.
