The rest is boon-waste. The breaking of 100 pounds of stalks requires, in theordinary routine of a double process by hand, about 20 hours; and with the above de-scribed machine, from 17 to 18 hours. To scutch 100 pounds of broken flax clean, 130hours of labor are required by the German swinging method. Mr. Bundy obtained a patent in 1819, for certain machinery for breaking and pre-paring flax, which merits description here. Fig. 423, a A A a, is the frame, made either of.
