Mr. Boyd, in the lecture before referred to, says that some years ago, when resident at Genoa, he was one of the members of a committee for procuring a new floating chapel for the use of seamen. The old chapel was built on the deck of a hulk, but the extremely high summer temperature caused the repairs to be both frequent and costly. The committee therefore wanted the new chapel to be built of iron, but were deterred by the fear that its roof and sides, exposed to the sun, would get so hot as to render the interior unbearable. He therefore proposed to fill up the space between the outer skin and the inner boarding with asbestos ground to a rough powder; and this suggestion was adopted, the powder being tightly rammed in by the carpenters. The result, he informs us, was so successful that whilst the outside temperature stood at 100°, the temperature inside, when doors and windows were kept shut, did not exceed 70°. And he therefore suggests that asbestos powder might be used in a similar way for rendering the deck cabins of steamers navigating the Red Sea and Suez Canal more comfortable for the passengers. For wall and ornamental papers it is being largely used, and a superior quality of asbestos writing paper is now being made in Paris. One can easily imagine a great future in this line for asbestos paper written or printed on with asbestos ink for all kinds of registers and permanent records, bankers' and merchants' books, and the like. One of the leading manufacturers in New York already prints his price lists on asbestos paper. And another has on show fine papers as susceptible of receiving good impressions from type as any in use in modern books. Coloured wall papers also are manufactured in great variety, which are not merely incombustible, but practically indestructible by fire; and which retain, even after severe heat tests, their colourings, markings and letterings as clearly impressed and as vividly visible as before. Boards also are made of asbestos, varying from the thinnest and lightest card to heavy shelving, fit either for partitions in safes or for use in large libraries. In a recent number of "L'Industrie Moderne" I found an account of a new process invented by a Mr. Ladewig for manufacturing pulp and paper from asbestos fibre, which he asserts will not only resist the action of both fire and water, but will absorb no moisture; this pulp, he says, may be used as a stuffing and for the joints of engines. He further proposes to use it in the form of a solid cardboard as a roofing material for light structures.
