When this object is so clearly in mind it seems curious that so little attention has been paid to the temperature of store rooms for “ mellowing.” This question is not only bound up with efficient carding, but obviously with the oils em. ployed and fire insurance.

Blending Machinery.—Two or three machines are essential for blending, viz., the Shake Willey, the Willow or Willey and the Fearnought. The simple construction of the Shake Willey is shown in Fig. 8. It is made in several forms with one, two or more swifts. Its function is always simply to shake and in no sense to tear or tease the wool. The normal Willow consists essentially of (a) An automatic intermittent feeding apparatus. (b) A willowing or beating and tearing appar- atus; and (c) An automatic delivery apparatus usually linked up to the automatic feed apparatus. The construction and action of these parts will be * See Appendix. 28
