The Capture, Preparation, and Preservation of Specimens 



an opening in the rabbet with the interior. The paper lining the 

 inside is perforated over this opening with a number of small 

 holes. The pocket is kept filled with naphthaline crystals, the 

 fumes of which pass into the interior and tend to keep away pests. 

 The accompanying figure gives the details of construction (Fig. 

 69). Such drawers can be made at a cost of about $3.50 apiece, 

 and the cost of a cabinet finished and supplied with them is about 

 $325, made of cherry, finished in imitation of mahogany.

Some persons prefer to have the bottoms as well as the tops of 

 the drawers in their cabinets made of glass. In such cases the 

 specimens are pinned upon narrow strips of wood covered with 

 cork, securely fastened across the inside of the drawers. This 

 arrangement enables the under side of specimens to be examined 

 and compared with as much freedom as the upper side, and with- 

 out removing them from the drawers; but the strips are liable at 

 times to become loosened, and when this happens great havoc is 

 wrought among the specimens if the drawer is moved carelessly. 

 Besides, there is more danger of breakage. 



Another way of providing a cheap and very sightly lining for 

 the bottom of an insect-box is illustrated in Fig. 70. A frame 

 of wood like a slate-frame is provided, and on both sides paper is 

 stretched. To stretch the paper it ought to be soaked in water 

 before pasting to the frame; then when it dries it is as tight and 

 smooth as a drum-head.
