omplete,
but if required for an incomplete collection, the risk and annoyance
of unscrewing and screwing up, to constantly remove or insert a
specimen, are great.
In view of the almost impossibility of keeping dust out of even the
best-made cabinet drawers, if made on the top-lifting system, and also
to do away with the screws, I have devised what I call the "dust-proof
cabinet drawer." The glass is "beaded" and puttied in as a fixture on
the top of the drawer, either from the inside or out. At the usual
distance from the glass, to clear the pins, a strip is fixed all
around the frame of the drawer. Below this, at a depth settled by the
thickness of the bottom, a groove runs all around, except at the back,
which is cut out up to the bottom edge of the groove. The bottom, when
corked and papered, fits inside the frame, "butting" up to the strip
which clips it all around to about the width of 0.25 in. A false
bottom now slides in the groove below, and fastens with a catch,
making all perfectly secure and altogether dust proof.
If well made, this drawer is easy to open, as, directly the false
bottom is removed the inner one slips down and is found on the table
when the upper part is lifted off. The only thing to be said against
this drawer is that the fronts show a little deeper than usual to
allow for the extra bottom.
A modification of this is a closely glazed cabinet drawer, with a
false corked bottom, loosely held down by a slip affixed to each side
of the drawer, and sliding out from the back; managed by hinging the
back piece or fixing it by brass eyes and hooks. Note, that all loose
flaps to drawers or door-frames, in best cabinet-work, should be
worked and fitted by "Dust-joint" planes. This reduces risk and dust
to a minimum.
PINS.--The pins used are those called entomological, and are made in
various sizes to suit various insects. An insect should be pinned with
one of these exactly in the centre of the back, running through truly
to the underneath, slanting, however, a little downward toward the
body, thus throwing the pin's head a little forward, but exactly in a
line with the longest axis of the body. These are specially made by
one or two firms only. Messrs. D. F. Tayler and Co, of Birmingham,
issue a sample card, the most useful sizes of which are No. 11 (at 6d.
per oz.) for the hawk moths, No. 13 (at 6d. per oz.) for smaller moths
and butterflies, and No. 7 (at 2s. 6d. per oz.) for small moths, and
