Insects should be mounted as soon as pos- sible after being killed. When it is impossible to mount them immediately, put the insects in shallow pill boxes packed in tis- sue paper, and set in a warm place to dry. When ready to mount, remove the lid and place the box in a tight glass jar, together with a sponge dipped in camphor water. The insects should be left in this chamber for from 24 to 48 hours, when they can be mounted as usual. Insects should be mounted on insect pins. These are made especially for the purpose, are about an inch and a half in length, and range in size from No. 000, the most slender, up to No. 8, which is the largest. Nos. i, 2, and 3, however, will do for nearly. Fig. 47S. Pinning forceps all purposes, with a few of No. 5 for the larger moths. No. 3 is large enough for almost all larger insects, and insects too small for No. I should be mounted on points. The pins may be obtained in either the black japanned or the plain white metal; the latter, however, should be used only in mounting insects on points, as a green verdigris is produced near the insect, which corrodes the pin. The collector should be careful to have all the insects at the same distance from the head of the pin; this not only makes the 343.
