men wrapped
in silver or tissue paper. It is astonishing what a number of them
will pack in this manner in the compass of an ordinary cigar box.

"Drying houses" are sold by most of the dealers, but are expensive and
cumbersome, and are really only of service when travelling, or
collecting away from home. For this reason I suggest the
following--which is a store box and receptacle for setting boards
combined.

Make of 0.5 in. deal a box 20 in. long and 15 in. wide by 0.5 in. deep
(all inside measurements), glue up all but the front piece (4 in. wide
by 20 in. long), which merely tie in its place whilst glueing up the
others. Cut the box when dry through the 4 in. back piece to exactly
halve it. Hinge each half with strong hinges. It now resembles an open
backgammon board box, without its two fronts.

Take now a strip of 1 in. deal, 15 in. long, and form it with a plough
plane to the shape shown in Fig. 49. The part marked A will be 0.375
in. thick, the parts marked B B overhang 0.25 in, and rise from A to B
B to the height which the thickness of your setting boards determine.

Divide this down the whole length with a cutting gauge where shown by
the dotted lines; glue one of these halves to the side of one of the
bottoms of the box, and from here measure off 5 in, which will be the
size of your largest setting board for hawk moths. At this point glue
down a whole strip, as shown in Fig. 49, which (supposing you have
commenced from your left) clips the right-hand side of the first or 5
in. setting board, and the left-hand side of the second. Proceed in
this manner until the bottom of the box is covered with setting
boards, which will now slide in and out between the 0.375 in.
divisions. Turn the box round and do precisely the same with the other
half.

As many more insects under, than above, 4 in. in expanse of wing will
be captured, the most useful sizes for setting boards, as also the
proper proportions of boards and divisions to fill up the bottom of
each half of the box, are as follow:

First half.--0.25 in. strip, 5 in. board; 0.375 in. strip, 4 in.
board; 0.375 in. strip, 3.5 in. board; 0.375 in. strip, 3 in board;
0.375 in. strip, 2.5 in. board; 0.25 in. strip = 20 in. total.

Second half.--0.25 in. strip, 3.5 in. board; 0.375 in. strip, 3 in.
board; 0.375 in. strip, 2.5 in. board; 0.375 in. strip, 2.5 in. board;
0.375 in. strip, 2.25 in. board; 0.375 in. strip, 2 in. board; 0.375
in. strip, 1.5 in. board
