ARTIFICIAL WOOL TESTS.
Id general appearance artificial fabrics are hard to distinguish from the genuine wool article, but when one was recently admitted to a shrinkage test by immersion in wirier and then allowed to dry normally, the result was a shrinkage to almost half tho 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 edgo of the sample and applying a lighted match, and the result was (piite startling. The material flared up and burned rapidly, as though soaked in petrol. The artificial article will not withstand tho heat, or cold as efficiently as wool, the natural clothing of tho sheep, which is almost a non-conductor of heat and is non-inflammable. Economically and hygienically wool has all the properties ideal to lmnivi use to a far greater extent than any other material, and man has so far failed in his efforts to vie with Nature in tho production of a substitute.
