[101] COLLECTING AND PRESERVING INSECTS RILEY. 



The drawers (Fig. 118, A, B, 0) are square, with an outside measure- 

 ment of 18 inches and an outside depth of 3 inches. The sides and 

 back have a thickness of three-eighths of an inch, while the front is 

 five-eighths of an inch thick. The pieces are firmly dovetailed 

 together, the front being clean and the dovetailing blind. The bottom, 

 a, is of three-ply crossgrained veneer, run into a groove at the sides, 

 leaving a clear inside depth of 2,--^^ inches to the frame of the cover. 

 The bottoms are lined in all but forty of the drawers with first quality 

 cork, &, one-fourth of an inch thick. At a distance of one-fourth of an 

 inch from the sides and back and three-eighths of an inch from the 

 front there is an inside box of one-eighth inch whitewood, c, closely 

 fitted, and held in place by blocks between it and the outer box. There 

 is thus between the inner and outer box a clear space, fZ, all round, in 

 which insecticides or disinfectants can be placed to keep out Museum 

 pests, making it imiDossible for such to get into the inner box contain- 

 ing the specimens without first passing through this poison chamber. 

 The entire inside is lined with white paper, or, in the case of the 

 uncorked boxes, painted with zinc white. The front is furnished with 

 a plain knob. The cover is of glass, set into a frame, /, three-fourths 

 of an inch wide, three-eighths of an inch thick, with a one-fourth inch 

 tongue fitting closely into the space between the inner lining and outer 

 box, which here serves as a groove. This arrangement furnishes a per- 

 fectly tight drawer of convenient size and not unwieldy for handling 

 when studying the collection. 



The material of which these drawers are made is California red wood, 

 except the cover frame, which is mahogany. The cabinets containing 

 these drawers are 36 inches high, 40 inches wide, 21 inches deep (all 

 outside measurements), and are closed by two paneled doors. 'Each 

 cabinet contains twenty drawers in two rows of ten each, and the draw- 

 ers slide by means of a groove, //, on either side, on hard-wood 

 tongues, and are designed to be interchangeable. 



n^lie Lmtner display Box. — For beauty and security and the perfect 

 display of the larger Lepidoptera, I have seen nothing superior to a 

 box used by Mr. J. A. Lintner, of Albany, N. Y. It is a frame made 

 in the form of a folio volume, with glass set in for sides and bound in 

 an ordinary book cover. The insects are pinned onto pieces of cork 

 fastened to the inside of one of the glass plates and the boxes may be 

 stood on ends, in library shape, like ordinary books. For the benefit of 

 those who wish to make small collections of showy insects, I give Mr. 

 Lintner's method, of which he has been kind enough to ftirnish me the 

 following description : 



Figs. A, B, and C represent, in section, the framework of the volume, a showing 

 the ends, h the front, and c the back. The material can be prepared in long strips 

 of some soft wood by a cabinet-maker (if the collector has the necessary skill and 

 leisure for framing it) at a cost of 60 cents a frame, if a number sufficient for a dozen 

 boxes be ordered. Or, if it be preferred to order them made, the cost should not 

 exceed 80 cents each.
