in the glass, which should have been
perfectly cleaned; lay in the passepartout and fasten it with small
brads. Then lay the crayon down on the table face up and turn the frame
over on it, and after you have it in the proper place, draw the picture
and frame partially over the edge of the table, and from underneath
mark the back of the passepartout where the edges of the picture come;
then turn the frame and picture over so that it shall be face down. Now
cut eight strips of old tin-type metal one-quarter of an inch wide and
three inches long, making holes at each end of them for the tacks, and
with these strips fasten the picture in its place by tacking one end of
each to the strainer and the other end to the frame. Also cut a piece
of heavy manilla paper the size of the frame, lay it on a board, dampen
it with a sponge, apply starch paste around each side and the ends for
a space of six inches, and lay it over the back of the picture and
frame, pressing it down on the latter; then set it away to dry. This
will make a neat smooth back which will exclude moth and dust from the
portrait.

PASSEPARTOUT MOUNTING.

The following method will be found useful, especially if you want to
exhibit a crayon without the expense of framing it. Lay on the mounting
board a piece of heavy manilla paper somewhat larger than the picture,
then put the crayon on this face up, next the passepartout, and last
the clean glass. Mark the size of this on the paper, and then, having
removed the glass, crayon and passepartout, cut the paper enough larger
than the marks to allow it to come up one inch all around over the
edges of the glass; next dampen the paper, and apply the starch paste
to its edges about six inches all around, then lay the crayon,
passepartout and glass back where they were on the paper, and bring the
latter up, lapping it over the face of the glass; cut the corners out
so as to bring them over properly; rub the edges down thoroughly on the
glass, and with a ruler and knife trim off the paper, allowing
one-quarter of an inch margin; then set away to dry. This will put the
crayon in good condition to be exhibited, and will thoroughly protect
it.
