Complete Revolution IN Roofngl
1.-THE PLASTIC SLATE For
Roofing and other purposes.
Patented February 2lst, 1865.
YYvHIS INTERESTING DISCOVERY
u was made known to the world by the
Farmers Club OF New York, at their meet
ing in the latter part of June. 1866. and its
was earnestly discussed; but the inventor
William L. Potter, of Clifton Park, y. Y,
has been carefully experimenting with the
material for many years, and has demon
strated its utility and practicability.
After suffering many partial failures in
compounds of lime in all its various forms
and phases-in sand, granite, plaster, min
eral coal, clay of various kinds, marble
dust, soap-stOne, cement, coal-tar, vege-
table tar, asphaltum, etc.-in all the pro-
ligent and inventive mind could suggest,
for fourteen gears. He tried the slate-stone
also, in many combinations, before he dis
covered that natures aw OF reconstruction
was exceedingly simple, requiring only
gluten to hold the particles in connection
till time and the action of the elements
firmly unite them.
If ever a roof leaks, it will be owing to
other causes than the decay of the cover
ing. 1t will be because the water goes
round, not through it. 1t is uneQLoIed as a
paint over new tin, and would preserve 1t
many years without further attention,
and Should be used for that purpose in
stead of paint. 1t will repair all defects in
old TN roofs, such as rust-holes, cracks, and
breaks, making them permanently WaLcf-
proof, and more durable, at much less cost
than tin-smith could afford 10 do it, even
In his imperfect manner. Old roofs OF
every description can be repaired much
more durd6ty and cheaply with Plastic
Slate than with any o her material eXtant.
Coal-tar is found to be the viscious ele-
ment alike of coal and slate; and IL was
discovered not inUented, and scientific in
vestigation, as well as experience, fully es-
tablishing the fact that its exposure to
heat and cold, wet and dry, serves only to
reconstruct the two elements In their con-
ditlOn-SoLID SLATE.
PLASTIC SLATE Is SUPERIOR TO TIN
1. because 1t is better non-conductor OF
heat. The rooms under ii will be cooler
in summer and warmer in winter.
2. 1t will not rust.
3. 1t will not break or crack open like tin
does where Jolnted.
4. 1t is less dangerous, DIR. Tyng's church
one of the finest in New York, was burned
in November, 1865. causing loss of $3.50.
600, from a fire in its tin root, from the bra
ziers of some naen who were repairing it.
5. 1t needs no painting, which on tin
AMOUNTS in few years to the entire cost
of Plastic Slate Roof.
6. Because IL costs haJ as much, and lasts
ts0ice as long.
