"HIS INTERESTING DISCOVERY
was made known to the world by the
Farmers Club OF New York, at their meet
ing in the latter part of June. 1885, and its
importance to u country and the world
was earnestly discussed but the inventor,
William L. Potter, of Clifton Park, N. Y,
has been carefully experimenting with the
material for many years, and has demon
strated its utility and practicability. fHa
After suffering many partial failures in
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-
portions and combinations that an INTEL
llgent and inventive mind could suggest,
Tor fourteen years. He tried the slate-stone
covered that natures iaw demonstration
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 uneQuaJed 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 tan roofs, such as rust-holes, cracks, and
breaks, making them permanently water
proof, and more durable, at much less cost
than a tin-smith could afford to do it, even
IN his imperfect manner Old roofs of
every description can be repaired much
more durdbly and cheaply with Plastic
Slate than with any other material extanu.
Coal-tar is found to be the viscious ele-
ment alike of coal n slate; and it vas
discovered, not fnUented, and in
tabiishing the fact that its exposure to
heat and cold, wet and drv, serves only to
reconstruct the two elements in their con-
d"ftion-SoLID SLATE.
