ly up to that of the old; the tool should not be allowed
to work against the walls of the old aperture, as there is much risk
of damage or enlargement and the necessity of a fresh peg, which is
to be avoided, if the set of pegs have been doing their duty well and
are free from splits. In the fitting of the peg, a degree of tightness
into the new wood will be found advantageous; the surface being fresh
and softer than that of the old, soon accommodates itself during the
insertion and revolution of the peg, whereas the process will have been
going on a long time with the old walls which have become hardened.
After a few turns with the inserted peg, the fitting of it will have
been tested, and if satisfactory, it may be taken out; a piece of soft
chalk stroked down and followed by a piece of very dry old soap in the
same manner at the parts coming into contact with the interior walls
of the aperture and will stop any squeaking or catching. The proportion
of soap to chalk must be varied, the one, soap, being increased
according to the catching or jerking and lessened if there is too much
slipping and no grip. It may be as well to note at the same time that
the peg should be quite circular, or it will revolve by fits and starts
notwithstanding soap and chalk, or any other mixture.

CHAPTER V.

FRACTURE OF PEG-BOX AND SHELL--CHIPS FROM THIS PART--FILLING UP OF
SAME--RESTORATION TO ORIGINAL FORM, AFTER PARTS HAVE BEEN LOST--WORN
PEG-HOLES, RE-FILLING OR BORING SAME.

We may now take another degree lower down and study the treatment best
for a fracture similar to that last described, but which, if at one
of the lower peg-holes, may appear quite as difficult to manage, if
not more so, as at the upper part, in consequence of the curved form
of the shell or lowest part of the grooved back of the scroll. Firstly,
the cleansing must be effected and drying, as previously with the upper
fracture, bringing or pressing the parts together for testing their
accuracy of fit. The cramp must be again brought into use. Owing to
the wider and deeper hollowing of the back at this part and the longer
and often very unequal continuation of the line of contour, the shell
or tail end sometimes curling up more abruptly than usual, an increase
in the substance of the padding against the cramp will be found
necessary. A piece of cork cut or filed to the shape will prove handy
and effective. The superficial area of the interior walls of this
