Steam pipes have recently been
made Of ramie fiber, hardened under
tremendous hydraulic pressure, and
possessing tensile strength equal to
two and one half times that Of steel.
The ramie hber, or China grass, has
the property Of being unaffected by
moisture: It will not shrink nor swell
it is non-conductor Of heat II car
not rust, and these features. together
with its great strength, are all desir
able in steam pipes, its utilization il
this line being regarded. therefore. a.
one of the possibilities of tho future.
