greatest success; Of course, being
perfectly freproof. The only sup

light iron rods across the buildings.
One bridge over which we walked,
was built by Mr.. Boch's father in
l841, across a small stream in his
park, and is ffty-four feet long, six
feet wide, with an arch of about four
feet rise; and being united by iron
rods, scarcely shakes with any ordi |
nary weight. Every few years it re-
ceives coat of tar and sand.
WHITE AND coLoRED STONE CHINA.
The Europeans use more colored
ware than We do, and some Of the
vases, &c, are beautifully painted;
but much white ware is also made
not strictly transparent porcelain,
but of fine quality such as sells in
the United States under the name of
stone china or granite ware. The
materials for the body" of this ware,
as made at Mettlach, are chiefly clay
from near Worms, with kaolin from
Navarro in France, and grey pipe clay
from Nielsen in Saxony, mixed with
ground burnt-fint aud felspar. The
glaze is silicate of alumina, or almost
a glass, being composed of fine clay
ground by a series of revolving quartz
rocks, then freed from all grit by pas
sing through fine wire gauze and
cloth, (the filtration aided, as in

in the glaze, then allowingit to dry, and
afterwards exposing it to high heat in
the kilns. These are usually about
sixteen feet across inside with various
fues near the outer diameter of the
dome, reaching half way up its sides,
the heat afterwards descending by
central aues, having permeated the
ware In its sagger cover. For the
finest articles, muffies are used, and
fine rods of ware are laid so as to pre-
vent any two pieces from touching.
The latest improvements have been
adopted In every respect, and there
are patents for heating, drying, &C.,
connected with the steam engines.

thorough arrangements for healthful
ventilation, streams of air being sent
from below for the removal of dust
from around each machine whenever
it arises, while the workman is
smoothing the edges and performing
similar dry finishing work.

gives four or five orders each year.
MERTzIa TILE WORKS.
Besides manufacturing tiles for
and for fire proof roofs and
bridges, this establishment makes
tiles to receive large panes of glass, so |
that roofs thus constructed can be |
fully lighted by the use Of these at
suitable intervals; one pave tile being |
equal to two common roof-tiles.

also made of tasteful patterns; and
