All insects except beetles should be pinned through that part of the body just back of the head, as shown in Figs. 137, 139, 140, 141. Beetles should be pinned through the right wing-cover, as shown in Fig. 138. About one-fourth of the pin should project above the back of the insect. Very small insects may be gummed to a narrow strip of card board and the pin put through the card board. LABELLING SPECIMENS. Specimens should be labelled with the date of capture and the locality. Thus the butterfly, Fig. 141, would be labelled thus: Ithaca, N. Y. Aug. 12, 1896. The paper on which this label is written should be slipped upon the pin with which the butterfly is pinned and placed just below the insect. Labels should be as small as possible and be neatly cut. INSECT BOXES. For the beginner nothing is more convenient than an empty cigar box, which may be obtained at any store where cigars are sold. (Fig. 131.) The bottom of the box should be covered with some soft, firm material into which pins may be pushed without bending them. There are many such materials. Sheet cork or pressed peat may be obtained of dealers in entomological supplies. Some ingenious boys use regular bottle corks, cut into cross sections about 1/4 inch thick. Others take the pith of dried corn-stalks divided in half lengthwise. The cheapest and most easily procurable of the purchasable materials is cork linoleum. This is for sale in most carpet stores. Get the quality that is about 1/4 inch thick, which costs about $1 per yard; put it into the box cork-side up. Any of these materials can be fastened to the bottom of the box with glue or with tacks. In all cases they should be covered neatly with white paper, for the insects appear better against a white background. [Illustration: _Fig. 131. A convenient box for the use of the young collector._] For permanent collections, wooden boxes with glass tops are much safer; and as the insects may be seen through the glass these boxes are more practical for school collections. This kind of a box is shown in Fig. 132. Its sides are 18 by 16 inches and its height is three inches outside measure. The upper edge of the sides of the bottom part of the box is made with a tongue which fits into a groove made in the lower edge of the sides of the cover. This is done so that the top and bottom parts of the box shall fit very closely together in order that museum pests cannot get in and destroy the specimens. [Illustration: _Fig. 132.
