ARTIFICIAL WOOL TESTS
In general appearance the artificial fabrics are bard to distinguish from the genuine article, but when one was recently submitted to a shrinkage test by immersion in water, and then allowed to dry normally, the result was a shrinkage to almost half the original size. On another piece of the artificial material the hot head of a match was dropped, and it immediately passed right through. A third test was carried out by fraying the edge of the sample and applying a lighted match, and the result was quite startling. The material flared up and burned ra.pidiy, as though soaked in petrol. The artificial article will not withstand heat or cold as efficiently as wool, the natural clothing of the sheep, which is almost a non-conductor of heat, and is non-inflammable. Economically and hygienically wool has all the properties ideal to human use to a far greater extent than any other material, and man has so far failed in his efforts to vie with nature in the production of a substitute.
