Steam pipes have recently been
made of ramie fiber, hardened under
tremendous hydraulic pressure, and
possessing a tensile strength equal to
two and one half times that of steel.
The ramie fiber, or China grass, has
the property of being unaffected by
moisture: it will not shrink nor swell,
it is a non-conductor of heat 1t can
not rust, and these features, together
with its great strength, are all desir-
able in steam pipes, its utilization in
this line being regarded, therefore, as
one of the possibilities of the future.

John w. Bookwalter, who owns
10000 acres of land in Nebraska pro-
poses to initiate great reform in farm
life, at an expense of $75, 600 or $780,

His idea is to bring the farmers homes
together into tastefully arranged
village near each ones land, instead
of having them on the individual
farms He has already started the
experiment on small scale, and says:

and establish free circulating
