1t appears that special attention is
being paid in France and England to a
more general substitution Of iron and
steel for wood. wherever practicable,
in manufactured articles. such. for in.
stance. as building materials. boxes and
packing cases. barrels or casks. car
riages or carts, and other vehicles. fur.
niture. fencing. railway work. sheds,
signal boxes. telegraph poles. etc. In
Franco there have recently come in use
window frames and doors.
which are said to be light and strong
and Of far greater durability than could
ever be assumed of wood. There is no
too. it is thought why CORFU.
gated barrels of iron or steel should
not be used for liquors. since milk and
fruits and other articles are
kept in cans. Steel is finding much
favor among carriage builders, but
there is still much prejudice against
the metal being used in the manufac.
ture of furniture.
