For _sculpture_, photography will often be the only method of reproduction possible to the traveller. When that is the case he may be advised (1) to take his photographs on the largest possible scale; (2) to take the object from all possible points of view; (3) to do what he can to improve the light and relief of the subject. Small objects gain enormously by reflected lights carefully arranged to bring out their contours; if sufficient mirrors are not obtainable, strips of tin or even white paper will serve as reflectors. Backgrounds may be chalked or blacked as the case may be, but in the case of a relief this should only be done when the outlines are very clear. If a sculpture on rock or other material is much broken or worn, a good mechanical method of improving relief, which Professor Petrie recommends, can be used; this consists in dusting the face with powdery sand and then fanning it. The result, if carefully done, is to leave hollows and background in strong contrast to the surface of the relief. Highly polished or lucent surfaces should be dulled before photographing. Metal objects do not, as a rule, photograph very satisfactorily; and of coins it is much better to take a cast and photograph that. Perhaps it is not superfluous to remind the photographer to make notes of all colouring before leaving his subject. On preparing sculpture, etc., for photography there are valuable practical hints in Professor Petrie’s ‘_Methods and Aims in Archæology_,’ Chapter VII. For _small objects of antiquity_, photography is not of much service unless a camera with very long extension can be used. If it be possible, the best way is to lay the objects on a sheet of glass raised about a foot from the ground on a frame, and arrange the camera above, so as to photograph downwards. This process obviates all ground shadows, and all pins or other supports for the objects, which appear sharply on the negative as if suspended in air. For _buildings_ photography is, of course, the only method of mechanical reproduction possible. (_b_) _Moulding._—This in almost all cases will have to be done by impressing _paper_. Only in the case of small objects will a traveller ordinarily be able to use either _plaster of Paris_ (if he can procure it) or _sealing wax_. As to the latter he may be reminded never to heat his wax by putting it in direct contact with a flame, or the impression will come out so parti-coloured or black as to be of little use; a card should be held over a candle or lamp, or, better, a spirit burner, and the wax rubbed upon the gradually heating upper surface till enough has melted on to the card without boiling. A useful impression may be obtained of coins, gems, etc., by pressing ordinary tin foil upon the surface; but great care must be taken afterwards that the impression does not get flattened out in transport. Mr. Petrie recommends floating impressed foil on water face downwards, and dropping hot wax upon it, as a solidifying agent.
