As for wear--well, they all of them wear till
after we get tired of wearing them. Paper "vulcanized" by being run
through a 30 per cent. solution of zinc chloride and subjected to
hydraulic pressure comes out hard and horny and may be used for trunks
and suit cases. Viscose tubes for sausage containers are more sanitary
and appetizing than the customary casings. Viscose replaces ramie or
cotton in the Welsbach gas mantles. Viscose film, transparent and a
thousandth of an inch thick (cellophane), serves for candy wrappers.
Cellulose acetate cylinders spun out of larger orifices than silk are
trying--not very successfully as yet--to compete with hog's bristles and
horsehair. Stir powdered metals into the cellulose solution and you have
the Bayko yarn. Bayko (from the manufacturers, Farbenfabriken vorm.
Friedr. Bayer and Company) is one of those telescoped names like Socony,
Nylic, Fominco, Alco, Ropeco, Ripans, Penn-Yan, Anzac, Dagor, Dora and
Cadets, which will be the despair of future philologers.

This is now made into a large variety of useful articles of which a few
examples are here pictured]
Soluble cellulose may enable us in time to dispense with the weaver as
well as the silkworm.
