quickly enough for
cork modelling, and is not so good as the old plan; the sides and ends
are formed of cork sheets, marked with a lead pencil to represent the
blocks of stone; and ruined and broken parts imitated, by pricking the
cork with a blunt penknife or needle. The frieze, representing the
battle between the Centaurs and Lapithae and the metopes in
mezzo-relievo, containing a mixture of the labours of Hercules and
Theseus, should be drawn upon the sheets of cork according to scale,
and coloured with a little lampblack and raw sienna, to represent the
subject intended, if the scale is small; but if the model admits of
it, the groups may be neatly carved with a sharp penknife from the
cork, which has been previously outlined with pencil.

The next thing we shall have to do is to strengthen the interior of
the model, and this is done by glueing small pieces of cork, at
irregular intervals, at the angles formed by the junction of any
parts; these are put on the inside, and lastly, the roof is affixed.
Any parts that require to be coloured, may be touched up with varnish
or water colours, and lichen, &c., affixed with mucilage where it is
requisite.

2375. To Model from Living Objects.

We will imagine that the reader desires to model the features of some
friend, and as there is some difficulty in the matter, on account of
the person operated upon having a natural tendency to distort the
features when the liquid plaster is poured upon the face, and some
danger of suffocation if the process is not well managed, we will
proceed at once to describe the various stages of operating:

2376. Procedure (1).

Mix the plaster of paris with warm water, and have it about as thick
as cream, but do not mix it until all is ready. Lay the person upon
his back, and having raised his head to the natural position when
walking, by means of a pillow of bran or sand, cover the parts
intended to be cast with oil of almonds or olives, applied by means of
a feather, brush, or lump of cotton: plug the ears with cotton or
wool, and insert two quills into the nostrils, and plug the space
between each quill and the nostril very carefully with cotton.

2377. Procedure (2).

Cover the face with the plaster, beginning at the upper part of the
forehead, and spread it downwards over the eyes, which should be kept
_firmly_ closed, but not in such a manner as to produce
