There are thus twelve setting boards 15 in. long, of the most useful
sizes, contained in this box. The front is still as it was, open. The
loose piece of wood, 20 in. by 4 in, must now be cut down the length,
and each half must (making 20 in. by 2 in.) be hinged to the top and
bottom of the box; a lock can then be fixed to bolt together the two
halves, hooks also being fixed at each end of the box to further
secure the front flaps. Fig. 50 shows the arrangement of the box at
this stage--shut, but with the front flaps lifted up and down, showing
the "sliding" setting boards snugly fixed within. Insects may by
this method be left on the boards whilst travelling without the
slightest risk, as nothing can come loose, and the pins of one side
miss those of the other when the box is shut and locked.

A more simple plan, serving equally as well perhaps, and having the
advantage of dispensing with the intervening slips, therefore giving
more space for setting boards, is simply fixing a slip of wood at each
inner end of the box, and another on each flap, so arranged as to hold
all the setting boards down when shut. This is managed by allowing the
wood of each setting board to protrude beyond its cork to the
thickness of the slip--say half an inch. [Footnote: This box should be
made in oak or mahogany; put together with brass screws, if for
"foreign service."]

Insects, after removal from their "sets," require to be stored in
glazed cases or cabinets for greater security and protection against
evils previously glanced at. Some collectors content themselves with
using for this purpose the ordinary store-box, made in the same manner
as the collecting box, but of greater capacity. One 15 in. by 10 in.
by 4 in. deep will be found a useful size; this--opening in the same
manner as a backgammon board--is corked with cabinet cork, each sheet
of which is usually 11 in. by 3.5 in. or (double size) 12 in. by 7.5
in.

The cork being glued evenly over each half of the box, is rubbed down
with pumice-stone, and afterwards with sand-paper, to get an even
surface and reconcile the joints one with the other. It is then
papered with white blotting-paper, toned, or black paper, pasted down
over the cork with paste, in which has been previously stirred a
little carbolic acid or corrosive sublimate (both poisons).
