rtises or tenons, so that the cutting line may readily be
followed.

This is the most difficult tool to hold when in use, but that will be
fully explained under its proper head. Each kit should have two, as in
making mortises and tenons one gage is required for each side of the
mortise or tenon.

CHISELS.--Two kinds are found in every kit--one called the firmer (Fig.
7) and the mortising chisel. The firmer has a flat body or blade, and a
full set ranges in width from three-eighths of an inch to two inches.
The sizes most desirable and useful are the one-half inch, the inch and
the inch-and-a-half widths. These are used for trimming out cross grains
or rebates for setting door locks and hinges and for numerous other uses
where sharp-end tools are required.

[Illustration: _Fig. 7._]

THE MORTISING CHISEL.--The mortising chisel (Fig. 7_a_), on the other
hand, is very narrow and thick, with a long taper down to the cutting
edge. They are usually in such widths as to make them stock sizes for
mortises. Never, under any circumstances, use a hammer or hatchet for
driving chisels. The mallet should be used invariably.

[Illustration: _Fig. 7a._]

TRUSSES.--There should be at least two, each three feet in length and
twenty inches in height.

SAW CLAMPS.--These are necessary adjuncts, and should be made of hard
wood, perfectly straight and just wide enough to take in the narrow
back saw. The illustration shows their shape and form.

THE GRINDSTONES.--It is better to get a first-class stone, which may be
small and rigged up with a foot treadle. A soft, fine-grained stone is
most serviceable, and it should have a water tray, and never be used
excepting with plenty of water.

[Illustration: _Fig. 8._]

AN OIL STONE is as essential as a grindstone. For giving a good edge to
tools it is superior to a water stone. It should be provided with a top,
and covered when not in use, to keep out dust and grit. These are the
little things that contribute to success and should be carefully
observed.

THE MITER BOX.--This should be 14 inches long and 3" by 3" inside, made
of hard wood 3/4" thick. The sides should be nailed to the bottom, as
shown.

THE WORK BENCH.--In its proper place we show in detail the most approved
form of work bench, fitted with a tool rack to hold all the tools,
conveniently arranged. In this chapter we are more particularly
