y, and cleaned off
completely with benzol. It should be melted in an iron saucepan, as
solder will give way if it is superheated. As it melts at about 120
degrees F., and boils at about 600 degrees F., it can be greatly
superheated, and used when smoking, so as to penetrate deeply into
wood or porous material. It is perfect for strengthening skulls; most
rotten examples slopped with paraffin, and finally soused for a few
seconds so as entirely to cover the bone in and out, will travel
safely, if not crushed.

Boxes must always have corner posts, inside or out; see that the
sides are nailed up to the edges to the posts, or the lid or bottom
may part by the side splitting. See that all nails--except for the
lid--are driven slanting alternately one way and reversed, this
prevents sides or bottom drawing off. Nail the lid with many short
nails, so that it can be raised without splitting.

To secure heavy objects in a mixed box, an inverted rough stool is
the best, the cross piece on the object below, and the sides coming
up to the lid. If cross bars are nailed in a box, damage may be done
to an object in forcing the bars loose. It is often best to put heavy
and light things in the same box, to equalize weights in journeying;
if well secured, a mixed boxful travels well. Be very careful that a
wedge-shaped stone cannot force itself loose by repeated jolts, or it
may split a box.

Slabs of stone ire best packed in open shallow boxes face down on
straw or wool, secured by a few diagonal cross bars on the top, as
then they do not need to be opened for customs. All stones of regular
form should be supported at a fifth of the length from each end. No
bedding on a box is worth anything, as the box will bend more than
the stone, and the strain will all come on the middle. Very heavy
blocks are best with sacking on the face, and roped round in various
parts.

Pottery is most difficult to pack safely. For large jars, mark the
points of contact on the box, and nail on cushions of old cloth
stuffed hard with straw, so as to pad the jar on all sides; make sure
that it cannot twist about into a diagonal position off the pads.
Long boxes, five or six feet, with three or four cross divisions, are
best. Begin packing, say four pots with straw, at one end of the box,
press up a cross board tight on them, and nail through the sides:
then another batch likewise; about one inch thick of hard-pressed
straw is needful at each contact. Twist
