and lower tables, but slightly upwards or contrary to the tendency of the peg to accommodate itself to the strain. When the parts under strain have settled down, the peg is seen to be as near as possible horizontal with the length of the violin. The best way, undoubtedly, is to make the peg an accurate but not too tight fit, it should be sufficiently long to go right through the block. In cases where the hole has been enlarged, badly directed or even made ragged by a bad tool, it should be a stopped up very carefully with a plug, neatly glued in, and a fresh hole bored. Sometimes this has proved necessary from the carelessness of the original maker. The old masters were not always exact with their mechanical fittings in connection with the violin. The moderns, for obvious reasons, have paid much attention to them. I remember coming across an Italian violin that had changed hands frequently for the asserted reason of insufficient tone. The maker having a renown for considerable power, it appeared to me that the tone was possibly there, but that from some undiscovered cause it was not properly emitted. On examination I found that the maker had joined the ribs, not at the central part as usual, but too much to the left, perhaps a pupil or assistant had bored the hole at the junction. There were besides, some tinkerings by modern regulators endeavouring to counteract the uneven strain over the instrument. The right spot, or it may be called the axis of the instrument, having been found, the peghole was neatly and permanently plugged, and a fresh one bored, which allowed the strain to be better distributed. The result was satisfactory and delightful; the tone of much power and purity had free play in manifesting itself, and the violin was enabled to take its rightful position among its brethren. A few words as to the right spot for the peghole. This was treated by many of the old Italian liutaros as a matter for mere guess work apparently, when there was no join in the upper table, nor in the lower one, sometimes the lower rib being continuous. The best spot, and therefore the right one, may be fixed upon by finding the centre between the two inner edges of the purfling on the upper table at the lower part, the same between that of the upper, and drawing a faint line through the points with a piece of soft white chalk cut to a point, and guided by a flexible rule or straight edge down to the nut. If this line does not touch at the centre of the nut, then the latter is out of place, and it should be rectified. The line should pass through the centre of the nut, and immediately underneath this and midway between the edges of the upper and lower table will be the spot for the centre of the peghole. The line thus made will not always be found to agree with the centre joint of the pine; many of the old Italian makers may have not, from lack of wood of the right sort and in equal widths, been able to do otherwise. At times it may have been carelessness. Some of their roughly made violins have the joint line over a quarter of an inch from the centre, occasionally it will be not only wider on one side than the other, but the thread or grain will diverge instead of running parallel with the centre line. The judiciousness of careful measurement for the centre, instead of relying on the joint line, will therefore be obvious. There is not much to be said in preference of one kind of hard wood over another for the end peg, it being a matter of fancy as to appearance. Ebony being black and very hard, should perhaps take the preference in wear, and acquiring a polish from the gentle friction it is liable to. The old Italian end pegs were mostly of cherrywood, with lines neatly turned round a centre of ivory or bone.





CHAPTER IV.

INJURIES TO THE HEAD OR SCROLL—INSERTION OF FRESH WOOD—COLOURING OF WHITE WOOD—SEPARATION OF HEAD FROM PEG-BOX AND RE-JOINING—STOPPING MATERIAL FOR SMALL HOLES OR FRACTURES—THE PEG-BOX CRACKED BY PEG PRESSURE.


Leaving this part now, we can turn our attention for a time to reparation of injury to the head or scroll. This interesting and often highly artistic part of the general structure of the violin, and in which no man since the time of the old Brescian, Gasparo da Salo, has succeeded in effecting any permanent change of fashion, is subject to as many knocks as any other part. A piece out of the ear or first turn from the axis is, with a delicately carved scroll, so frequently seen as to be almost fashionable; little pieces out of the edges further off from the central part, are common disfigurements. Modern vandals rub these parts down with a file or glasspaper, to make it nice and even to their vision, saving themselves time and trouble. Many a graceful scroll, carved with loving care and enviable dexterity by a master of his art, has thus come to an untimely end. Should your cherished Guarneri or Stradivari scroll got chipped or fractured by accident and the piece drop, search for it at once, and when found, if you have not good mechanical ability and experience in fitting such delicate parts, it should, while fresh and free from soiling, be entrusted without delay to the care of a professional repairer of repute, but not to a provincial amateur or rough carpenter who would probably make matters worse. On setting to work after a preliminary inspection, the careful repairer will fit the parts together as they are, to ascertain that there is nothing to prevent a close join of the surfaces, sometimes a splinter will prevent a close fit of the surfaces; this must be pushed into its right position or, if in the interior, it may be better to remove it altogether. If the part is lost, then the bare space must be carefully examined and the direction of the grain and quality of the surrounding wood matched as closely as possible; otherwise the most accurate fitting and finishing off will not make a good restoration. The repairer of experience will have at hand a large quantity of odds and ends of different kinds of maple, curled or plain; perhaps old worn out necks or otherwise useless fragments of relics of a bygone age, and not necessarily of musical instruments. But sometimes these are not to be obtained, nothing but new or modern wood, and it may be of good appearance and applicable excepting for the colour. What is to be done? There is the drawback to new white wood, that it is difficult to colour down to match the surrounding wood, when it has been fixed, and besides, if the part happens to be where there is any friction, the white wood soon makes itself apparent, if not very conspicuous. It is advantageous, therefore, to colour the wood artificially before placing in position. There have been many ways adopted at times for meeting this requirement. It must be remembered, however, that there is no perfectly successful mode of artificially colouring wood so as to defy detection, but small portions such as are under consideration at the present moment may be treated so as to look tolerably well. Firstly, a well known, often tried, but very bad method is to steep a piece of white new wood in a solution of nitric acid and water. When dry, old age will seem to have crept over and through it, but of a delusive and unnatural kind. The corrosive properties of the acid still remain and gradually disintegrate the fibres until the whole mass becomes rotten. It may be fairly termed premature old age, as the lowering or toning down of the colour in wood and other materials seems to be caused by similar, if not identical, constituents of the ordinary atmosphere, but under different conditions. Another way is lay the pieces of wood upon a stove with a regulated heating
