Knowledge of Tools.—A knowledge of tools and their uses is the first and most important requirement. The saw, the plane, the hatchet and the hammer are well known to all boys; but how to use them, and where to use the different varieties of each kind of tool, must be learned, because each tool grew out of some particular requirement in the art. These uses will now be explained.
A Full Kit of Tools.—A kit of tools necessary for doing any plain work should embrace the following:
1. A Hatchet.

34. Spirit Level.
The Hatchet.—The hatchet should be ground with a bevel on each side, and not on one side only, as is customary with a plasterer's lathing hatchet, because the blade of the hatchet is used for trimming off the edges of boards. Unless ground off with a bevel on both sides it cannot be controlled to cut accurately. A light hatchet is preferable to a heavy one. It should never be used for nailing purposes, except in emergencies. The pole of the hammer—that part which is generally used to strike the nail with—is required in order to properly balance the hatchet when used for trimming material.
About Saws.—There are four well-defined kinds. First, a long, flat saw, for cross-cutting. Second, a slightly larger saw for ripping purposes. Third, a back saw, with a rib on the rear edge to hold the blade rigid, used for making tenons; and, fourth, a compass or keyhole saw.
Cross-cuts.—The difference between a cross-cut and a rip saw is, that in the latter the teeth have less pitch and are usually larger than in the cross-cut saw. When a cross-cut saw is used for ripping along the grain of the wood, the teeth, if disposed at an angle, will ride over the grain or fiber of the wood, and refuse to take hold or bite into the wood. On the other hand, if the rip saw is used for cross-cutting purposes, the saw kerf will be rough and jagged.
The back saw is used almost exclusively for making tenons, and has uniformly fine teeth so as to give a smooth finish to the wood.
Planes.—The plane may be called the æsthetic tool in the carpenter's kit. It is the most difficult tool to handle and the most satisfactory when thoroughly mastered. How to care for and handle it will be referred to in a subsequent chapter. We are now concerned with its uses only. Each complete kit must have three distinct planes, namely, the jack plane, which is for taking off the rough saw print surface of the board. The short smoothing plane, which is designed to even up the inequalities made by the jack plane; and the long finishing plane, or fore plane, which is intended to straighten the edges of boards or of finished surfaces.

The Jack Plane.—This plane has the cutting edge of its blade ground so it is slightly curved (Fig. 6), because, as the bit must be driven out so it will take a deep bite into the rough surface of the wood, the curved cutting edge prevents the corner edges of the bit from digging into the planed surface.
On the other hand, the bits of the smoothing and finishing planes are ground straight across their cutting edges. In the foregoing we have not enumerated the different special planes, designed to make beads, rabbets, tongues and grooves, but each type is fully illustrated, so that an idea may be obtained of their characteristics. (Fig. 6a).
Gages.—One of the most valuable tools in the whole set is the gage, but it is, in fact, the least known. This is simply a straight bar, with a sharpened point projecting out on one side near its end, and having an adjustable sliding head or cheekpiece. This tool is indispensable in making mortises or tenons, because the sharpened steel point which projects from the side of the bar, serves to outline and define the edges of the mortises 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.

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.
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 ¾" 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 concerned with the uses of tools than their construction; and we impress on boys the necessity of having a place for everything, and that every tool should be kept in its proper place. A carpenter's shop filled with chips, shavings and other refuse is not a desirable place for the indiscriminate placing of tools. If correct habits are formed at the outset, by carefully putting each tool in its place after using, it will save many an hour of useless hunting and annoyance.
One of the most important things in laying off work, for instance, on trusses, is the disposition of the saw and square. Our illustration shows each truss with side cleats, which will permit the user temporarily to deposit the saw or the square so that it will be handy, and at the same time be out of the way of the work and prevent either of the tools from being thrown to the floor.
In the same way, and for the same purpose, the work bench has temporary holding cleats at the end and a shelf in front, which are particularly desirable, because either a saw or a square is an encumbrance on a work bench while the work is being assembled, and tools of this kind should not be laid flat on a working surface, nor should they be stood in a leaning position against a truss or work bench.
Strictly observe these fundamentals—Never place a tool with the cutting edge toward you. Always have the racks or receptacles so made that the handle may be seized. Don't put a tool with an exposed cutting edge above or below another tool in such a manner that the hand or the tool you are handling can come into contact with the edge. Never keep the nail or screw boxes above the work bench. They should always be kept to one side, to prevent, as much as possible, the bench from becoming a depository for nails. Keep the top of the bench free from tools. Always keep the planes on a narrow sub-shelf at the rear of the bench.
If order was Heaven's first law, it is a good principle to apply it in a workman's shop, and its observance will form a habit that will soon become a pleasure to follow.
