vuvHIS 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, 1863, 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
strated its utility and practfcability.
After suffering many partial failures in
compounds of lime in all its various forms
eral coal, clay of various Kinds. marble
dust, soap-stone, cement, coal-tar, veee-
table tar, asPhaltnm. etc;min Pa, an the pro-
Hgent and inventive mind could suggest,
for fourteen gears. He tried the slate-stone
also, in many combinations, before he dis
covered that natures law of reconstruction
was exceedingly simple, requiring only
gluten to hold the pa ticles in connection
till time and the action OF the elements
firmly unite them.
III ever a roof leaks, 1t will be owing to
other causes than the decay of the cover
round not through it. 1t is uneQudted as a
paint over new tin, and would preserve IT
many years without further attention,
and should be used for that purpose in
stead of paint. 1t will repair all defects in
old tin roofs, such as rust-holes, cracks, and
breaks, making them permanently water water,
than a tin-smith could afford o do 1t, even
in his imperfect manner. Old roofs of
every description can be repaired much
more durabiy and cheaply with Plastic
Slate than with any other material eXtant.
Coal-tar is found to be the yiscous ele-
ment alike of coal and slate: and it was
discovered, not inrented, 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-
dition-SOLID SLATE.

1t is not necessary to match, or tongue
and groove the sheating-boards; but the
more solid, aud level, and close they are
laid, the better and more durable the roof
will be. They should by all means be sea-
soned. tH
a double lining of good roofing-feIt is
laid in shingle form, each edge eing fast
ened down with cIeats. This lining Is de-
signed to i7lsuiote the roofing from the
boards lest their shrinking and swelling
should injure the covering. After the pro-
cess of felting or lining the roof is COM
pleted, the mastfc, mixed to the consist
ency of thick mortar (bei,lg more than three
Jourths slate, is then spread upon the felt,
about one-eighth of an inch thick, with a

it will be better than when new.
