PREPARATION, CARE, AND DISPLAY OF INSECTS. 337 



makes it a point annually, in the early summer, to place suffi- 

 cient chloroform or carbon bichloride in his cabinet drawers to 

 exterminate anything 1 that may be living 1 there, and thus secures 

 comparative immunity from insect attacks. 



Instructions as to the use of labels may be restricted to the 

 simple advice to make them small enough to permit of their 

 beiug 1 placed upon the pins bearing the insects, and to have 

 them written legibly. Of course every label should bear, if 

 it is possible for the student to determine them, the generic 

 and the specific names of the insects, and that of the author 

 of the specific name, together with the date and locality of 

 capture. In writing labels a small crow-quill pen is to be pre- 

 ferred. 



A great many instruments of different sorts will suggest 

 themselves to the collector in the process of his labors as being- 

 more or less useful, but none will prove more so than the for- 

 ceps. It is impossible to do good work in the cabinet without 

 a forceps, and those made by Blake, of Philadelphia, are the 

 very best.
