WORLDS TALLEST CHIMNEY.

Above the Surrounding Country.
From Power.
Experience has shown that the height
of factory chimneys is not alone de-
pendent on how much smoke or other

essential that chimney, especially
| where IL has to remove poisonous and
other detritus products of combustion,
containing dangerous and unhealthy
poison, not alone for human beings. but
for plants as well. is to be constructed
to such height that the escaping gases
produce no harm, especially ut chemical
factories and gas works. where, in most
cases. the poisonous and dangerous pro-
ducts of combustion escape before they
enter the flue, thus demanding fire.

is often found impossible to carry out
After the experience of to-day, an
| outlet height of about three hundred
feet above the level, Is considered suih'
cient to prevent harmful action to plant
life. as we'll as the interference with
the health of people living In the viein-
ity of the chimney. Should this terri
tory be surrounded with wooded
| heights, It is well to increase in the
same ratio the height of the chimney.
In rolling or billy country, the outlet
of the chimney must be placed at least
three hundred feet above the highest

of this great height, cost so much that
It is cheaper to build the flue of the
chimney on this highest point, and
erect the chimney proper on the al

nature.
On account of this aforesaid condi-
| ton the Royal Saxon Smelling Works
at Halsbrucke. in Freiberg, were com
PEELED to build a high chimney. which
| can safely be considered to be the high
est and most prominent chimney of this
century. The chimney has height
above the surrounding plane OF 459 feet.
! The height of the chimney itself is 4z9
feet 6 inches, and, therefore, at the
time of its completion, in 1889, was the
highest chimney in the world. The top
internal diameter is about feet The
enormous height did not suffice to sup
ply sufficient security for the surround
ing neigh borhood against the outgoing
gases. and, therefore, this chimney was
erected upon one of the adjoining
highest hills. which Is 1876 feet higher
than the smelling works situated in
the valley. In consequence OF this po-
sition. the chimney obtains an addl-
tional height, an increased efficiency
equivalent 10 height of over 656 feet.
As this chimney could not be placed
next to the factory, but was built, as
before mentioned upon the highest hill
a flue of over $40 feet was constructed
which runs part of the distance over a
bridge. specially built to hold the con-
struction over he river Nude, which
separates the factory from the hill up
on which the chimney is built, thereby
reducing to rational amount the cost
of the construction, the outlet of the
said chimney being about three hun
dred feet above the adjoining plane.
| Notwithstanding this great saving by
the construction OF the fue, and util-
izing nature for the additional height,
the chimney alone cost over $31
the construction of the 1,64O feet OF
fue $4,000, hence the total cost Is
about $4,000, including excavations.
foundations. and the necessary iron
rings; the two latter items cost $500.
But even the tremendous cost has been
a good investment so far, as the COM
