YyyHIS INTERESTING DISCOVERY
u. was made known to the world by the
Fnrmers' Club OF New York, at their meet
ing in the latter part of June, 1865, and its
importance to our 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 It's utility and practicabilfty.
After suffering many partial failures In
compounds of lime in all its various forrns
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-
POI tfons and combinations that an intel
ligent and inventive mind could suggest,

also. in many combinations, before he dis
covered that natures aw demonstration
was exceedingly simple, requiring only
gluten to hold the particles In connection

round, n OF through 1t. 1t is uneQuoled as q
paint over new tin, and would preserve 1t
many years without further attention,

old TN 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 IL, even

every description can be repaired mncn

Coal-tar is found to be the viscious eie-
discovered, not fnvented, 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-
ldition-SOLID SLATE.
