For this purpose a rather small chisel of the kind known among cabinet makers as a mortising chisel will be required. Gently and by degrees the mass of superfluous maple will have to be removed. It must be borne in mind that maple or other tough wood will not bear the forcing that a piece of pine will. A hard-wood workman is essentially a man of degrees, the tougher the wood the less must be shaved off at a stroke. The strong, massive form of the mortising chisel is used in order that there may be as little spring as possible in it while cutting and so prevent a hacking of the parts instead of a clean cut surface; indeed, no other proportioned tool can be used with any degree of facility. It must not be ground to a very acute angle, or the objections that are sought to be avoided will reappear in another form. Great care must be taken that the mortising does not extend to a depth that will cause the back to be thin and weak. This mistake is often seen to have been committed in very valuable instruments, especially such as have the two grooves deeply modelled, or the contour downwards from the volutes is much indented. At times, on the other hand, sound judgment has been perceptibly directed to this part and instead of cutting away wood to allow of freedom in the winding of the strings over the pegs, the holes for these have been filled up and re-bored nearer to the front edges. Many most excellent old Italian makers seem to have been rather careless with regard to the exact position of the peg-holes, making them to be equi-distant from each other. There might have been little or no objection to this in the days when the strain on the pegs was not near what it is in the present times of very high pitch. The shaft of the old pegs used in Italy at the time of the great masters, was not half as thick as is thought expedient now. Towards the latter end of last century and the beginning of this, more attention was paid to the matter, and we accordingly find the two upper peg-holes much closer together and the two lower ones ditto.

Concerning the refilling or "bushing" as it is termed of the peg-holes, a few words may not be out of place. For the purpose the holes must be enlarged more or less or there may not be sufficient of the new wood to hold together when the re-boring takes place. The cutting must be truly circular and very sharply done, no tearing of the wood must be perceptible, but a clean, almost polished surface inside. A solid cylinder must be cut with great exactitude, of maple or the same kind of wood if obtainable as the scroll. The old makers did not invariably use maple, perhaps being unable to obtain it in sufficient quantities for their business purposes. It is useless to think of cutting the cylinder or rod any other way than with the grain, it is seldom if ever done, and moreover involves an expenditure of time and labour that brings no adequate return. The enlargement of the hole must be effected by a good form of tool and this in good condition; peg-hole cutters and fluted rimers are sold for the purpose. When the cylindrical rod is cut and rounded to make an exact fit, a portion can be cut off a trifle longer than will be apparently necessary so as to allow of finishing off. If satisfactory in all respects, recourse may now be had as to the solution of glue, which should be quite fresh and strong, as this is to be for a permanency. The rod or portion should be warmed if the season is cold, the glue allowed to settle round for a moment while some should be placed on the inner surfaces of the hole in which the cylinder is to form a solid fixture. When inserting the cylinder it should be worked round a little, but not jammed in with violence. Your reliance in repairing must not be in force but accurate fitting. The opposite hole to be used for the same peg must be made and treated in the same manner. Some repairers, for economy of time, would make a fresh enlargement right through the two opposite holes and push the rod through both and glueing same at one process, cutting it away from the interior of the peg-box when the glue has hardened, but this is risky work. One hole is sure to be larger than the other and the fitting scarcely likely to be accurate both sides.

When a sufficient time has elapsed for the glue to dry, a piece of hard, but not too thick, cardboard should have a hole made so as to allow of placing on the projecting part of the rod, which can be now sawn off close to the card. When this is completed and the card removed, a sharp flat chisel will then reduce it to the absolute level of the surrounding plain.

The next stage will be that of re-boring a fresh hole in a proper position. This must be carefully calculated, so that when complete the whole of the four strings will be independent of each other, the A string not being in friction with that of the G or the D not touching the E. If this is not attended to, much trouble will be given to the performer, the jerking or catching of the string during the winding up, not being caused by any difficulties with the fitting of the peg itself but by the string pressing on and being checked by the peg of another. The boring of the fresh hole and fitting of the peg is of course a similar operation to that just described, with the difference that the peg must be more conical, whereas the plugging must be as near equal in diameter as possible along the whole of its length. The preparation of the fresh peg to fit the new hole will be already evident as to its requirements. There is one detail to be noticed, however, that of boring the hole for the reception of the string. Of course the E will not require so large an aperture as the D. The latter will require the largest aperture of the four. If this operation is not conducted in a methodical manner, with a proper knowledge of the best treatment according to the material used for the peg, splitting will ensue, which is trying to the temper. When a peg is once split it had better be thrown aside as useless, the strain on it being unsupported by the solidity of the material. No wooden peg that has been split in the operation of boring for the string should be retained. It being necessary to use wood of the hardest or toughest consistency, the splitting tendency is increased as the grain is closer. There is discussion as to the best material for pegs, and here in my opinion the old Italian makers were wise in choosing the cherry wood seemingly abundant enough at their command. It is not so hard and brittle as ebony. Another wood was used by them, a kind of dark walnut, straight in the grain, but a little firmer than the rose wood so fashionable at the present day, which has a waxy consistency but accommodates itself to the jamming by the impetuous amateur who will have his way.

LOOSENING OF JUNCTION OF GRAFT WITH PEG-BOX, AND REFIXING SAME—GRAFTING, DIFFERENT METHODS OF PERFORMING THIS—LENGTHENING THE NECK—OLD AND MODERN METHOD—RENEWAL OF SAME—INCLINATION OF NECK AND FINGERBOARD WITH REGARD TO THE BRIDGE—HEIGHT OF LATTER, AND REASON FOR IT.

In our progress downwards from the scroll and its adjoining parts, before quite leaving it we may refer to a disorder sometimes occurring when the neck is modern and grafted on to the old scroll. There are several ways, or fashions it may be termed, in which this is effected. The most usual method pursued in England and Germany is that of sawing the head off at a part below the end of the shell and then chiselling a level passage so far as a straight surface makes it necessary along the floor of the peg-box. The sides are treated in the same way but the width across diminishes as they proceed upward. The solid graft is shaped, inserted, and afterward hollowed, but of this more presently. Like all other parts of the instrument, the junction or insertion of the neck or graft sometimes gets loose, from bad fitting chiefly, bad glue or prolonged exposure to damp. When the sides or back part give warning that they are likely to part, they should be loosened still more or separated and a little clean water on a brush inserted in the cleft where discoverable, the parts being pressed and worked together until clean, for all cracked or loosened joints will be found more or less dirty and greasy. Some strong glue can be then worked in, both sides pressed together by cramps and left to dry. The backing of a flat piece of soft wood with an interleaving of stout paper or, better still, millboard, must not be forgotten. If, as sometimes happens, the flooring of the peg-box threatens to part from the graft in contact, the same course of working out dirt and inserting good glue must be pursued. In pressing the back or shell of the scroll, this being of short and sometimes abrupt hollowing, the pressure on the substance of the wood direct would be dangerous to its form. The fibres of the wood at the edge are necessarily very short and brittle. A thick piece of cork should, therefore, be placed between the cramp and the hollow grooving or shell, a small block of moderately hard wood being placed inside the peg-box as an opposing pad or buffer, the cramp may then be screwed down fairly tight. The two operations, glueing and pressing the side parts and that in connection with the shell, must not be attempted simultaneously.

We may now, being on the part as it were, take up the subject of grafting and the different and best means of performing this somewhat exacting operation. Accurate calculation and sharp straight cutting are absolutely necessary for even moderate success in this undertaking. As before mentioned, there is more than one method of securing a neck to an old head. Each one carried out with the necessary skill and neatness can be made a lasting and highly finished piece of joinery. The mode adopted in England (see diagram 25) is the most ready and gives the least difficulty in a difficult undertaking. The solid end of the graft is chiselled or planed off to a slightly wedged form with a straight or square upper end which is measured to reach when inserted, nearly or just up to the lowest of the upper two peg-holes. Great care has to be taken in the cutting that the sides are equal, otherwise the scroll, when fitted, will look awry.
