If reliefs have been much weathered they can be made plain for
photographing by laying horizontal and covering with sand; on wiping
away the sand from the relief the ground will be left flat sand, so
hiding the confused hollows of weathering.

The safest way for drawings to travel is to post them at the nearest
post direct to where they will be worked up. The Postal Union takes
rolls of 21 cm. thick, 60 cm. long, up to 5 kilos as parcels, or
rolls of 10 cm. thick, 75 cm. long, up to 2 kilos by book post open
at ends. This is far better than carrying rolls by hand.

Wet squeezing. Where there is no colour, and the stone is strong and
not crumbling, a wet squeeze is the best copy. There are three
purposes for it, and the method differs for each; (1) thin single
sheet kept fresh on the outer face for photographing later; or (2)
single sheet well beaten in and patched, depending on pricking the
outlines and hand-copy from it, or blacking over the relief on the
inner side and photographing; or (3) double sheet hard beaten, and
patched in the hollows, for plaster casting afterwards.

For (1) there is no need to get an impression of the hollows to the
bottom, and the face of the paper should be smooth. A soft paper,
with little or no size, and a soft clothes-brush will do well for
this. The sheet should cover the whole inscription, or have as few
joints as may be. The stone should be dabbed with a wet brush so as
to saturate the face, the sheet of paper well soaked in water laid
upon it, taking care not to leave bubbles, and then dabbing firmly
with the brush will drive the paper into the hollows. If the stone is
polished or very smooth, it is needful to peel off the paper while
