directions for mounting apply to platinum or silver
enlargements, crayon or other kinds of paper, but not to bromide
enlargements. The bromide paper requires a different method of handling
on account of the gelatin surface, which when wet is destroyed by
contact with any dry substance, as the latter removes the gelatin.

For determining the proper position of photographic enlargements (bust
pictures) on the strainer, the following scale will be useful as a
general guide. When the size of the strainer is 16x20, 20x24, 22x26, or
25x30 inches, the distances from its top to the top of the head of the
portrait should be respectively 3-1/2, 4, 4-1/2 and 5-1/2 inches.

MOUNTING BROMIDE ENLARGEMENTS.

The first requisite for this is a water-tight tray, large enough to
hold the enlargements. A hard rubber tray can be purchased, or a wooden
one that will answer the purpose may be made. I use one of my own
construction that is cheap and serviceable. It is simply a wooden box,
27x32 inches and 4 inches deep, made of 1/2 inch grooved material and
lined with black oil cloth, not cut at the corners, but folded in. In
this, when about half full of water, lay the enlargement face up, and
let it remain in the water fifteen minutes. It should then be laid face
down on the wet cloth (which should be all ready) as described in the
preceding chapter, for mounting crayon paper. Care must be exercised to
have the cloth wet all over, for if there should be any dry spots in it
they would ruin the gelatin surface. With a cloth or squeegee remove
the water from the back of the enlargement and also from the cloth
around its edges, for if there is too much water on the edge of the
cloth it will work up into the paste and prevent it from sticking when
mounted. Now paste the enlargement and strainer according to the
directions given for mounting crayon paper, place the enlargement on
the strainer and rub it down by using the fingers wet in a little
water, or the squeegee can be used; and then trim off even with the
outside of the strainer. Avoid rubbing too hard along the edges, as by
so doing you will press out all the paste and it will not stick.

You can remount a bromide enlargement as often as necessary in case it
does not come out perfect, only bear in mind that you must not allow
anything dry to touch the surface when wet. But I should not advise you
to try more than three times directly on the strainer. It would be
better to mount
