The Capture, Preparation, and Preservation of Specimens. 51.—Butterfly in envelope. a comparatively small sum, are preferable because of their conve- nience. Many collectors, however, paper their specimens in envel- opes v^hich they make of oblong bits of paper adapted to the size of the insect. The process of making the envelope and of paper- ing the insect is accurately depicted in the accompanying cut (Fig. 52). The writer finds it good in the case of small butterflies to place them in boxes between layers of cheap plush or velvet. A small box, a few inches long, may be provided, and at its bottom a layer of velvet is placed; upon this a number of small butterflies are laid. Over them is placed a layer of velvet, with its soft pile facing the same side of the velvet at the bottom. On top of this another piece of velvet is laid, with its pile upward, and other specimens are again deposited, and over this another piece of velvet is laid, and so on. If the box is not filled full at once, it is well to have enough pieces of velvet cut to fill it, or else place cotton on top, so as to keep the layers of velvet from mov- ing or shaking about. A yard or two of plush or velvet will suffice for the packing of a thousand specimens of small butterflies.

We shall now proceed to explain the manner in which this is most advantageously ac- complished. Theinsectshouldfirstofallbepinned.

Setting- boards or setting-blocks are pieces of wood having a groove on the upper surface of sufficient depth to accommodate the
