As to the use of plaster of Paris it may be remembered that (1) the proper mixture is just as much plaster as will absorb the water, leaving none standing on the top; (2) the object must be well cleaned and soaped before being moulded; (3) the plaster must be applied _very rapidly_, in a thin coating all over the object at once: it can be backed with more plaster afterwards; (4) a surface of any size should either be moulded in sections, or, if done all at once, the plaster will probably have to be cut into sections afterwards for transport. To cut it, it is best to lay strings upon the object before moulding, which, later, can be pulled up through the plaster while still viscous. _Paper moulding_ or ‘_squeezing_’ is, however, the ordinary process employed. Any fairly strong _unsized_ paper will serve more or less well, but a special ‘squeeze’ paper is procurable in most large cities where there are archæological museums (_e.g._, in London, from Nutt’s, 57 to 59, Long Acre, W.C.; in Paris, from Moreau’s, 11, Passage du Pont Neuf; in Berlin, from Ebers Brothers. It can also be got direct from the maker, Papierhändler Dorr, Spiesgasse, Strassburg.) Mr. Maudslay recommended in a previous edition a hand-made paper, used for packing oranges in Spain, and to be obtained of Messrs. Batalla, of Cacagente, near Valencia, through the agency of Messrs. H. King & Co., Cornhill. Failing these, the paper on which the commoner news-sheets are printed will do. The other implements needed are a sponge, and close-bristled, not very hard, brushes of two or three sizes, _e.g._, an ordinary clothes-brush, a nail-brush, and a tooth-brush, if no others are at hand, but special brushes with hand-straps on the back, or curved handles to keep the knuckles of the beater away from the stone, are preferable. In the case of an ordinary inscription, of not specially rough or uneven surface, brush and clean the stone thoroughly, and pick all accumulation out of the letters; then wet it thoroughly all over; lay the dry paper, cut to size, as flat on the surface as possible, and dab it down with a very wet sponge till thoroughly soaked; take the largest brush and pound the paper rather gently all over, till it partially adheres; then take smaller brushes and work the paper into all depressions with the maximum pressure you can exert; finally, hammer it with the large brush again, working systematically from top to bottom or side to side, not minding the surface becoming mashed, and driving the air-bubbles, which collect under the paper, before you and out at the farthest point. If the stone was thoroughly wetted before the paper was laid on, these ought not to be numerous or troublesome. Then, if the surface of the stone has penetrated through the paper at any point, lay a second sheet and, if necessary, a third, or more, and treat as the first was treated. Leave the sheets, if possible, to dry on the stone, and all will come off as
