THE PENRHYN SLATE COMPANY
ELEAZER JONES, MANAGER.
                         ------
  The extensive quarries of the Penrhyn Slate Company, situated at
Middle Granville, Washington County, in the northeastern part of the
State of New York, five miles south of Poultney, [Vermont] have been
operated on a large scale for a number of years, in the production of
the celebrated Purple, Green and Variegated Slate for roofing
purposes-beautiful in color when used separately or in combination, and
of great strength.

  Slate possesses some very remarkable and peculiar properties.  It may
be split into sheets as thin as a pice of card board; it is a conductor
of heat; does not tarnish with oil or great spots; resists the action of
most of the acids and alkalies; can be wrought to any design, plain or
ornamental, by machinery or any sharp steel instrument; yields freely to
the saw or rasp, and a smooth or satin-like surface is produced by
planing and rubbing.

  Previous to the year 1838, slate was mostly used for roofing,
flagging, he beds of billiard tables, educational purposes, etc.; but at
the date mentioned, a process was discovered and practically developed
in England, whereby slate was made to present the beautiful appearance
of the rarest marbles, and a polish put upon its surface which few of
them could be made to attain.  So perfect indeed, are the imitations,
that a very close examination is required to distinguish between the
original and the copy.

  The warerooms of this Company at Middle Granville, and at No. 40 West
18th Street, New York, should be visited by all who are desirous of
seeing to what perfection this art has attained.

  When every American home can thus be enriched and improved with
handsome chimney-pieces, ornamented furniture and various useful
articles-all at a very moderate cost, who can say that we are not moving
rapidly, and in the right direction?
