A LOST ART
Recovered.
Contractor John ]. LumSden in
Possession OF a Valuable
Secret.

The immense aquaduct which
brings the water from the hills 10
miles away, for the great city of Rio
de Jsneiro, has been the wonder and
admiration of travellers who visited
hat South American city. To archi-
tects it has been study and to me-
chanical engineers it has stood as an
unanswered problem for it seemed
utterly impossible for them to COM
prehend how it was possible. more
than four hundred years ago. for
workmen with the means at their
command, to raise those enormous
arches, more than eighty feet high,
and containing stones fifty feet long
and twenty feet wide. to their pres
ent position. however there were
those whose interest went far enough
to carefully investigate them and af-
that the great stones were made in
their position. the material being
carried to the top of the supports in
buckets. ON the heads of slaves,
where it was allowed to harden until
it is capable of sustaining pressure
of 1900 pounds to the cubic inch. one
of the strongest building materials
known AT the present day. 1t was
farther ascertained that although ages
had elapsed since its construction.
there were no signs of crack or crew
ice. but perfect surface with an ad-
amantine hardness. To unlock the
secret of this wonderful discovery and
again place in the hands of builders
this valuable knowledge was a most
important. but difficult task. and one
which required much research and
careful study. But by interesting the
descendants of the mighty builders
and exhausting ASSAYS it was finally
discovered and the world is again in
possession of the art of manufacturing
stone. brick. ornaments. sidewalks.
tile and u hundred other very valuable
assessories to present life and hsppi-
ness. without the use of heat These
materials may be made in any shape
and any color. or tint. and will in
much more lasting. than cast iron.
The fact that the water is crystalized
in the brick instead of being evapor-
ated by heat, prevents the material
from shrinking in the least. hence
there can be no cracking of fracture
of their surface, most desirable con-
sideration.
To acquire this information spent
two years in the city of Rio de janet
ro, among the natives and succeeded
which l have disposed of to Contract
ors in different parts of the east and
west. where it is the material which
has been chosen. after the most rigid
tests. for the heaviest buildings and
foundations of the present day. Side
walks made from this material will
maintain an unbroken surface for
ages. while their smooth and un-
yielding nature adapts them to the
most demanding taste.
In recommending this material for
any and all kinds of wear 1 wish to
make no mental reservations what
ever, as it has been proven, both by
time and the highest, qualified to
judge, to be the superior of every
thing heretofore known.
Sidewalks have been laid. brick
manufactured and ornamental tile
moulded right here in Grand juno
tion. and will continue to be made
for all time, as well as universally
used, when once their beauty. worth
and adaptability ale known.
This is to certify that l have this
day sold to contractor ]. J. Lumsden
of Grand Junction Colo. the sole
right to use the formula for this ever
lasting cement, west of the Rocky
mountains. in Colo. have also
instructed him in its manufacture
and he is in possession of complete
knowledge as to its use and manufac-
ture. Those interested may see
samples at his Office and on the
streets of Your city.
