As might be expected, asbestos is also found in China, but, as a matter
of course, the use to which it is put there is one we should little
dream of here. For instance, in the translation of a Chinese medical
book by Dr. Hobson, of the London Medical Mission, asbestos is seen to
figure (of all places in the world) under the head of _tonics_, in
company with such heterogeneous substances as "dried spotted lizard,
silkworm moth, human milk, parasite of the mulberry tree, asses' glue,
stalactite," and a few more surprising things. Perhaps it may be just as
well for us that we are not yet educated up to so fine a point as that,
and that consequently the mineral we are speaking of does not yet find a
place in the British Pharmacopoeia, but is left to exhibit its
apparently more natural properties in the arts and manufactures.
A correspondent of _The Financial News_, writing from Barberton in
January, 1888, says that at Komali Fields, fifty miles from that place,
asbestos has just been found, but that it was as yet too soon to discuss
the merits of the find.
In sending you an account of the Canadian asbestos industry, you will
scarcely expect me to give you any very detailed information about its
Italian competitor. Any account of the one, however, would necessarily
be so incomplete without some mention of the other, that I will do the
best I can with the little information I have been enabled to obtain on
the subject of the Italian mines.
Experiments with the view of utilizing asbestos in Italy appear to have
been first successfully carried on in 1850 by the Chevalier Aldini, of
Milan, and others, mainly with the object of turning the mineral to
account in the manufacture of asbestos cloth. The Chevalier had a
complete suit made of it--cap, gloves, tunic, and stockings--for the
purpose of testing its protective powers for firemen; and of this I
shall have something to say presently.[3] But it was not until twenty
years after this that any success was attained in the manufacture of
asbestos millboard and paper, the commercial value of which is now
assuming such large proportions.
About the same time the manufacture of asbestos into packings for piston
glands was successfully accomplished in America; and some two years
afterwards a company, calling itself "The Patent Asbestos Manufacturing
Company, Limited," was formed in Glasgow for the purpose of making
piston packings according to this American invention. In 1880 this
Glasgow Company united its business with that of Messrs. Furse Brothers
and Co., of Rome, asbestos manufacturers, as well as with that of the
Italo-English Pure Asbestos Company, and, when the amalgamation was
complete, the new Company, taking the name of "The United Asbestos
Company, Limited," became possessed of nearly the whole of the known
Italian mines, and, consequently, of a practical monopoly of the trade
in asbestos from that country.
