rerders to learn what has been done
with the same material elsewhere,
The Vanne aqueduct for supplying
water 10 the city of Paris is thirty
seven miles in length, embracing
from two and half to three miles of
arches of uniform span of thirty nine
and one-third feet, and also eight or
ten bridges of from seventy-five to
one hundred and twenty-five feet
span, with a thickness at the crown
of fifteen and three-quarter inches.
The lighthouse at Port Said,
Egypt, is one hundred and eighty
feet high, without joints, and resting
upon a monOlithic block of concrete,
containing nearly four hundred cubic
yards.
At Vesinet, near Paris, an entire
Gothic church, also a complete mono
18th, with its foundations, walls and
steeple, was built; the steeple being
one hundred and thirty..feet high, and
is in a perfect state of preservation.
The entire floor of this church is
paved with the same material in
variety of beautiful designs, and with
an agreeable contrast of cOlors.
In constructing the municipal bar
racks of Notre Dame, Paris, the
arched ceilings of the cellars were
made of this concrete, each being a
single mass. The spans varied from
twenty-five to twenty-five feet, the
rise in all cases being One-tenth the
span, and the thickness at the crown
eight and two-third inches In the
same building the arched ceilings of
the three stories of galleries, one
above the other, facing the interior
and all the subterranean drainage,
comprising nearly six hundred yards
of sewers, are all monoliths of con-
crete.
Several large houses, some six
stories in hight, have been construct
ed in different cities. In these the
entire masonry, comprising both the
exterior and partition walls, the
chimneys, with f1ues, cellar arches,
cistern, ETC., is single monOlith of
concrete.
Concrete has been in general use
for more than quarter of century,
and in the numerous and varied ap-
plications which have been made of
1t in Europe, America and elsewhere,
it has received the most emphatic
Communications from all prominent
engineers and architects.
For warehouses, churches and
large buildings of every description;
for foundations, quay walls, light
houses. ietties and piers; for abut-
ments and massive walls of all kinds;
for sidewalks, platforms and tagging,
and for many other minor purposes
concrete possesses not only compare
tive cheapness, but all the essential
merits of brick and stone with respect
to strength, hardness and durability;
while for many purposes, such as
cellars and cellar floors, cisterns,
reservoirs, tanks and fountains;
arches, vaulted ceilings and vaults,
tunnels, aqueducts, sewer and water
pipes, and ornamental work of every
description within the province of
the architect or engineer, it possesses
advantages peculiar to itself, and not
equally shared by any other ma
terial.
The contract for the remaining two
stories of the police building, which
will be of brick, has been let to Mr..
E. B. Thomas, who will commence
operations shortly, and we hope soon
to chronicle the completion of build
ing which, though it may not be a
'joy forever" to some. will be an OBJ
ject of pride to those of our citizens
who may not be forcibly detained
therein.
