APPENDIX I. 291 



Some, however, still prefer smaller sizes for convenience 

 of study, and use boxes shaped like a quarto volume, the 

 cover hinged and the whole lined with binder's cloth. 

 The volumes can then be lettered on the back and 

 arranged as in a library, and certainly have a neat ap- 

 pearance. Such books can be made safer either by a 

 bevelled wooden rabbet where the top and bottom 

 meet, or by arranging within a second glass cover, but 

 they can never be made so fully proof against pests as 

 an unhinged drawer. 



A very common box, but unsafe so soon as a collec- 

 tion becomes at all large and cannot be constantly 

 watched in every part, is a simple wooden box nine by 

 fourteen inches in size, in which both top and bottom, 

 made separate, are put to use by being lined with cork. 

 In this case the box must, of course, be much deeper. 

 Such cases can be made in numbers for fifty cents each, 

 exclusive of the cork, and answer very well for begin- 

 ners, but will be discarded after a time if the collection 

 increases, unless the owner has sufficient leisure and 

 patience to watch his treasures carefully. 



Insect-drawers of the modified Deyrolle pattern de- 

 scribed above will be made, on ordering a considerable 

 number, by Leander Greeley, 113 Broadway, Cam- 

 bridgeport, Mass.
