A five- or six-knife machine is capable ofchaffing the straw into half-inch lengths as fastas it falls direct from an ordinary threshingmachine ; and over a large portion of the coun-try the two operations of threshing and chaffing by one ordinary steam engine are commonlyperformed. There is great saving in this, asthe straw falls from the shakers on to the chaff-cutter platform, and can be fed into the feedbox by a mechanical feeder without furtherhandling; the risk of injury from wet, and theprobability of twisted straw through stackingbeing avoided. Those who are accustomed towork these larger machines find it difficult torealize why others use smaller machines. Thereis, of course, the greater initial expense; butwhere there is a considerable quantity of chaffrequired for feeding, there is undoubtedlyeconomy in using the larger machines. All largemachines are provided with means to conveythe straw in the feed box to the knives, and thelarger machines have an endless webbing run-

Riddles of various gaugestake off coarse mater,ials and sift out heavy dirt,and many machines are fitted with blasts oraspirators to clear out dust, so that a perfectlyclean chaff is made.
