One breaking machine of this construction is capable of supplying 12scutching stands of the ordinary mill.

Once passing through the machine is quite sufficient to prepare the flaxstraw thoroughly for being scutched. The force required to drive it is one 300 will best show its construction and mode of action. It having been found that many disadvantages were inherent in the old scutch-mill, sev-eral persons have set themselves to work to supply a machine which would reduce the costof labor, obviate the necessity of obtaining skilled workmen, and diminish the great waste offibre, which was but too frequent in the ordinary mill. Among the most successful of thesescutching machines is an invention of Mr. MacBride, of Armagh, Ireland, ^^s. 301, 302. It 301. consists of a cast-iron frame, at each end of which is a compartment, enclosing a double setof beaters of peculiar construction, which revolve rapidly in a contrary direction, strikingalternately on each side of the flax, as it is submitted to their action, and thoroughly remov-ing the woody part, which falls down in dust into a pit or hollow under the machine. Inorder to carry the flax gradually through the machine aud present it in a proper manner to FLAX. 543 the beaters, in succession, an endless double rope is introduced, carried in the hollow of alarge grooved wheel, in which it is kept tight by means of tension weights. The flax straw,made into handfuls, is introduced at a, under the double rope at one end of the machine,and is at once grasped by it firmly, rather above its middle, and carried along slowly, by themovement of the grooved wheel unt
