PREFACE.


The substance of the following pages was originally comprised in a
series of Letters from Canada to a friend in London, who was desirous of
obtaining all the authentic information possible on a subject on which
so little appears to be generally known.

The use of Asbestos in the arts and manufactures is now rapidly assuming
such large proportions that, it is believed, it will presently be found
more difficult to say to what purposes it cannot be applied than to what
it can and is.

Under these circumstances, although much of the information here given
is not new, but has been gathered from every available source, it is
hoped that the compilation in its present shape may be found acceptable.

ASBESTOS.


One of Nature's most marvellous productions, asbestos is a physical
paradox. It has been called a mineralogical vegetable; it is both
fibrous and crystalline, elastic yet brittle; a floating stone, which
can be as readily carded, spun, and woven into tissue as cotton or the
finest silk.

Called by geologists "asbestus" (the termination in os being the
adjective form of the word), the name of the mineral in its Greek form
as commonly used (+asbestos+), signifies "indestructible." The French
