But when her husband had expressed great wonder and admiration
over the paper made from that particular pulp, and had sold it in London
at an advance of several shillings over the price of his other paper,
which had not met with any such accident, she realized that the time for
silence had passed. Her account of the happy accident led her grateful
husband to purchase a costly scarlet cloak for her on his next visit to
London town. This accident brought about another result which was to
prove of inestimable value to the future paper-maker--the use of bluing
in paper when especial whiteness is desired.
Important as the bluing or coloring is, however, it is only one of the
numerous operations or manipulations that take place in the beater. Many
of these, such as engine-sizing and body-coloring, require skill and
constant watchfulness. Here, too, if anywhere, adulteration takes place.
It is sometimes necessary to secure a fine-appearing paper at small
cost, and it is profitable to add to its weight. In such cases a process
of "loading" takes place here, and clay or cheap, heavy fibers are
added.
