Mr. Boyd, in the paper so often referred to, says in regard to this, that he was some time previously asked to supply asbestos yarn spun in such a way as to have good capillary action, and, on making inquiry, found it was to be used for the above purpose. In describing the mode of using it, he says that there is placed over the opening rising from the sewer a hood of galvanized wire, interlaced with this asbestos yarn, the ends of the yarn dipping into a receptacle filled with liquid disinfectant, which, as they become saturated, form a disinfecting screen, through the meshes of which the gases rise, and in their passage through are purified and rendered innocuous. The system hitherto previously adopted for deodorizing sewer gas has been to cause it to rise through charcoal, but it is found that the impurities soon clog this up, and simply prevent the passage of the gas, whereas in the arrangement just mentioned (which is that of Messrs. Adams & Co., of York), the gas rises freely, and is perfectly deodorized.
There are, of course, very numerous other applications of the material which might be referred to or described, but probably those already mentioned are the most important and the most interesting; and these, it is hoped, are at any rate sufficient to indicate the great value of this singular mineral product, as well as to confirm the statement with which I started, that this is indeed one of Nature's most marvellous productions.
FOOTNOTE:
[10] There is a Patent Removable Covering now manufactured in New York which is said to be entirely formed of pure asbestos fibre, made in cylindrical sections of three-foot lengths of the exact size of the pipes to be covered. In this the asbestos fibres are so interlaced, that the sections, whilst possessing strength and flexibility, afford so large a number of air-cells as to give the covering the very highest non-conducting quality, whilst at the same time it cannot char or be in any way injured by the most intense heat from without or within. Fire Felt sectional coverings for boilers and large surfaces are made in convenient forms in sheets, &c. The same Company also manufacture what is called a Superator Jacket, both fire and waterproof, being in fact a flexible sheet of asbestos strengthened with wire netting, the asbestos being waterproofed by a special process, and provided with patent lacings, so that the jackets may be effectually kept in place, whilst being readily removable without cutting or loss of material.
