ARRANGEM-ENT OF TI-IE COLLECTION r9<br />

throughout the <strong>collect</strong>ion - whether they are read from the right<br />

or left is a matter of De$onal Dreference.<br />

An insect <strong>collect</strong>ion should-contain some identification labels.<br />

How these are best arraneed will deoend on the size of the <strong>collect</strong>ion<br />

and the extent <strong>to</strong> whiah it is ideniifed. Most <strong>collect</strong>ions should<br />

be labeied at least <strong>to</strong> order and {amiiv. and the soecimens so<br />

aranged that a sing'e label can se.ve I'or all t\r specinens in a<br />

group. When specimens are labeled <strong>to</strong> species, an identiication<br />

label is placed on each specimen or on the first in a group. This<br />

label is a plain piece of paper (about an inch square and at the base<br />

oI the pin) containing thc scientific name oI the insect, the name<br />

of the person identifying it, and the date (month and year) the<br />

identihcation \r'as made.<br />

Bores for Pinned Insects. Pinned <strong>insects</strong> are kept in bores<br />

having a soft material in the bot<strong>to</strong>m <strong>to</strong> pcrmit casy pinning; they<br />

can be obtained from a supply house or be homemade. f'he most<br />

common supply house type is a Schmitt box, a wooden box about<br />

9 x 12 x 211 in. \\.ith a tight-litting lid and the bot<strong>to</strong>m lined with<br />

sheet cork or similar material. Such boxes cost from a few <strong>to</strong><br />

several dollars. Similar boxcs made ol heavv cardboard are available<br />

from suoolr hou,e, anJ cr,,r on. hcll io orc rhicrl as mu, h.<br />

Homcmade bo*6s -ay be made of rvood or heavy cardboard, and<br />

the bot<strong>to</strong>m lined rvith sheet cork, balsa wood, Styrofoam, or corrugatcd<br />

cardboard. <strong>The</strong> material in the bot<strong>to</strong>m should 1it tightly,<br />

and if corrugated cardboard is used it should be soft enough <strong>to</strong> take<br />

an insect pin. Large <strong>collect</strong>ions ma1' be housed in Schmitt boxcs,<br />

or in cabinets contairing trays or drarvers constructed like Schmitt<br />

boxes,<br />

Riker Mounts. A Riker mount is a glass-<strong>to</strong>pped box containing<br />

cot<strong>to</strong>n, with jnsccts on the cot<strong>to</strong>n just under the glass. Insects<br />

spread lor mounting jn a Riker mount are spread in the upsidedown<br />

position descrihed on p. 15. Riker mounts may be of various<br />

sizes, and also can be purchased from a supply house or he hom"-<br />
