square cardboard, equally and partially divided--is then to be glued
on, and the chimney--formed of a piece of lucifer match, or wood
notched at one end and flat at the other--is to be glued on, A square
piece of cardboard must be glued on the top of the chimney; a hole
made with a pin in the card and wood; and a piece of grey worsted,
thinned at the end, fixed into the hole for smoke.

2365. Public Buildings.

Cathedrals, churches, and other public buildings are made in the same
way; but require the addition of small chips of wood, ends of lucifer
matches, cork raspings, or small pieces of cardboard, for the various
ornaments, if on a large scale, but only a pencil-mark if small.

2366. Starch-Paste or Pipeclay.

When constructed of starch-paste, or pipeclay, the material is rolled
flat on a table or marble slab, and the various sides cut out with a
sharp penknife; they are then gummed together, and coloured properly.

2367. Large Models.

If large models of houses or buildings are made, the windows are
constructed of talc or thin glass, covered with net or muslin. The
frames of the windows are made of cardboard, neatly cut out with a
sharp penknife.

2368. Countries.

Countries should be made of cork, because it is easier to work.
Although the starch-paste is very agreeable to model with, yet it is
liable to shrink, and therefore, when in the mass, one part dries
quicker than another, so that there is not equal contraction--a great
objection to its employment in accurate models. Cork, on the contrary,
may be easily cut into all forms, and from abounding with pores, it is
remarkably light--no little consideration to travellers.

2369. Topographical Models.

Topographical models may, however, be formed of plaster of Paris, but
the weight is an objection. A model of a country on a moderate
scale--say one-eighth of an inch to a square mile--with its mountains,
valleys, and towns, may be thus made:--A model having been first made
in clay, according to scale and plan, moulds should then be taken of
various parts in gutta percha, rendered soft by dipping it into hot
water, and the parts cast in paper cement.

i. Reduce paper to a smooth paste by boiling it in water; then add
an equal weight each of sifted whiting and good size; boi
