full-bodied, well-boiled
printers' varnish, using a little soap and drying preparation to make them
work smoothly and dry quickly.

In mixing tints to print with, the muller should be used to rub in the
colors thoroughly, otherwise the work is liable to be streaky. It is
advisable to mix no more of a tint than is needed for the work in hand.
Most colored inks work best if applied to the rollers a little at a time,
until the depth of color desired is reached, as colored inks distribute
slower than black, and are more liable to thicken upon and clog the type
when too much is taken at once.

HINTS ON "CASTING UP."

The most simple and effective contrivance for casting-up work is, for
every printer to set up, in vertical parallel lines, the m's of each font
in his office, with figures in succession beside them, and work them upon
good hard paper, but little wet or pressed, which ought to be dried very
gradually. If the cast-up work printed with the same type as these
measures very little variation will be found; for if the measure and the
measured page do vary from the measurement, the one is compensated by the
other. But even this method can scarcely be trusted in setting the price
with the compositor, since the difference between a thin and thick space
will carry an en quadrat, and thus may give the turn in the 500 letters,
so as to make 1,000 difference.

HOW TO ASCERTAIN THE QUANTITY OF PLAIN TYPE REQUIRED FOR NEWSPAPER.

To ascertain the quantity of plain type required for a newspaper,
magazine, and other work, find the number of square inches and divide the
same by four; the quotient will be the approximate weight of the matter.
As it is impossible to set the cases entirely clear, it is necessary to
add 25 per cent to large fonts, and 33 per cent to small, to allow for
dead letter. This, of course, is only approximate, but will be found
sufficiently close for all practical purposes.

CARE OF WOOD-CUTS.

Care should be taken that wood-cuts are thoroughly dry before being sent
to the foundry, as the intense heat to which they are subjected frequently
causes them to warp and split, especially if pierced.

REMEDY FOR TYPE THAT STICKS IN DISTRIBUTING.

Great difficulty is sometimes experienced in distributing type which has
been allowed to remain in form for any length of time. Prevention, of
course, is better than cure; but where the remedy is required, the
following may be tried with advantage:--Pour b
