Silk printing, also, 224 CALICO PRINTING, is chiefly confined to handkerchiefs, but the printing of woollen fabrics or mousseline delaines is an important branch of the art. The first step in calico printing is to remove the fibrous down from the surface of thecloth, which is done by passing the piece rapidly through a flame of gas, or over a red-hotsemicircular plate. The latter method will be found described under the head of Bleach-ing ; the former is performed as follows :—Fig. 95 is a vertical section of the gas-singeing 95 AA. apparatus. Its diameter is such as to admit of pieces of the greatest width. The pipe aruns along from end to end under the machine, and is supplied with ordinary gas ; the pipesB B are branched into this, being five in number on each side. Connected with thesebranches are the pipes, c c, which are perforated with fine holes, at distances of about ^ ofan inch; the pipes b b are furnished with taps, a a. Above the tubes c c are the pipes, d d,which are cut open at the bottom along the length, and communicate by the branch pipes,F F, with the large pipe, e, which is exhausted by a fan. Two pairs of cylinders, g g, ofwood, covered with fustian, turn on their axes in the direction of the arrows, and drawthrough them the pieces d cl with a velocity of about 4 feet per second. The pair of rollers,G G, to the right, are moved by a belt and pulley ; the other p
