1883. Excerpt: ... tion of modern architectural science. The art of
erecting chimneys for steamengines, and for similar purposes, has,
however, fared somewhat better, since all the more substantially
useful part of architecture, comprising nearly the whole of that
appertaining to manufacturing industry, has for some time past, in
our northern counties at least, merged into the province of the
civil and mechanical engineer, technically known in Lancashire as
the factory engineer. Factory engineers, however, though differing
widely from architects generally on many points, are not at all
agreed among themselves as to the best form and construction of a
chimney for attaining the principal end in view; namely, the best
draught at the least expense. In short, the problem of how to give
a sufficient velocity to the air passing through the fire-grate,
with a given temperature in the furnace or in the escaping
products, and at a minimum rate of consumption of the fuel to be
used, has scarcely yet received and adequate solution, even
theoretically. Practically, the question has received many
solutions--too many, one may say, for the convenience of ordinary
business men--which circumstance is one of the main causes that has
rendered the present work necessary, as well as contributing to
some of its chief difficulties. The multitude and diversity of
opinions on this subject may, in a great measure, be ascribed to
the generally prevailing reliance on the dicta of some few popular
professors, or rather amateurs, of chemistry; in which category we
might also, perhaps without much injustice, include a few so-called
scientific guide-books. I am not for decrying the present
inundation of cheap scientific treatises, which is so marked a
feature of the times; but, on the contrary, think such ...
