amount of steam and electrolytic bleach liquor. The pulp circulates slowly around the tiled tank under careful temperature control and when the bleaching is completed is dropped down into vats floored with perforated tile, where it is drained and thoroughly washed, in order to remove all traces of chlorine that may remain. After the showers of filtered water have been turned off and the pulp allowed to drain for a while, it is stirred and diluted by a heavy stream of cold water from a hose, so that the milk-white mass will flow through pipes to other thickeners which deliver the pulp at a constant density to the stock chest in order that a uniform sheet of pulp may be secured on the pulp machines. These pulp sheets of uniform moisture content make possible absolute exactness in the use of raw material in the paper mill. This is largely responsible for

the constantly uniforrri quality of Systems Bond.

FIRST STEPS IN THE PREPARATION OF RAGS

After a few minutes of this treatment the rags go to the sorting room, where they are sorted by hand into different grades, according to their quality. This operation is done by women who stand before long tables to each one of which a knife is fastened. With this knife the sorter opens seams and cuts off buttons, hooks and eyes and rubber. This done, the rags are again inspected by other women, "overlookers,"
