The presence in dyewood extracts of coloring matters in various stages
of development has hitherto militated against their use in place of
the raw materials by many dyers and printers who are still employing
inherited and antiquated processes in which the whole of the coloring
matter is not rendered available. It is often asserted by these that
even the best of extracts fail to give anything like the results
attained by the use of well-prepared woods, and that, indeed, their
application proves a complete failure. Such failure, however, is
simply due to the want of chemical knowledge on the part of the dyers,
for there is no real difficulty in making any good and pure extract
serve all the purposes for which the woods were used. It is to be
hoped that in this branch of industry, as well as in many others, the
employment of chemists will become more general than at present, and
not be restricted, as is often the case, to young men without
experience and without the trained intellect so essential to success
in chemical investigations. High class chemical skill is of course
available to the manufacturer, but the man of science who brings
matured knowledge and valuable brain work into the business required
social as well as pecuniary recognition, and the sooner and more
fuller this fact is appreciated the better it will be for the
maintenance and progress of our industries.
