is the color that is best adapted to most prints. A very attractive
card-mount is what is called a "plate-sunk" mount. The card has a
depression in the centre a little larger than the print to be mounted,
and has the effect of a frame. This card is of heavy board and rather
expensive, yet it pays to buy a good card-mount for prize competition
pictures.

Never mount a print on a card only a trifle larger than the print. The
picture should have at least an inch-wide margin all round. A 4 x 5
print should be mounted on a 6 x 8 card, and larger prints on
correspondingly larger cards. Do not use what is called a 4 x 5
card-mount for a 4 x 5 picture. If you have never used a larger mount
than one which just fits the picture try an unmounted print on a large
sheet of plain paper, and see how much the picture gains in beauty by
having a wider margin to the mount.

A nice way to mount prints for exhibition is to first mount the print on
a plain card, and then place a mat over it of rough water-color paper,
or such paper as is used to mat pictures. In using a mat do not trim the
photograph; mount it in the centre of the card, and then place the mat
over it.

Mount your pictures in as neat and attractive manner as possible, and
see if it does not raise your standard of "technical excellence."

SIR KNIGHT FRED. P. MOORE asks if there is any way to fix a
defective plate that has holes or scratches on the film; if
chemicals can be bought at drug stores, and are they cheaper or
dearer than those bought of the photograph dealers; and would also
like the formula for paste given over again. A negative that has
scratches in the film can have the holes or scratches filled up in
this way: apply retouching fluid to the spots in manner directed
on bottle. When it is dry take a soft lead-pencil and mark or
pencil out the spots, filling them with the soft lead. Be careful
not to mark any place except where the holes and scratches are, as
all such marks will show in the print. It is best to experiment
with a spoiled negative first before attempting to retouch a good
plate. A little practice and a steady hand will soon enable an
amateur to retouch the spots in his negatives so that the print
will show a perfect picture. It is much cheaper to buy
photographic chemicals at the regular dealers; for instance, I
bought 5 grs. of ferricyanide of potassium at the
