specimen is placed in the fold, the edges turned, to prevent 

 it coming apart, and a number marked on it referring to the 

 record. 



The record book should be kept with great care, as on 

 it depends the real value of the collector's work. In every 

 bottle should be placed a slip, with a number on it referring 

 to your record book. 



One of the best ways of preparing the latter, is to rule 

 off your pages and fill them out as the following example 

 illustrates : 



Now, having collected your specimens, the next step is 

 to mount them. 



For pins, get those made by Herman Klaeger. No.'s 3 

 and 5 will do for all ordinary specimens, but a larger as- 

 sortment of sizes is, of course, desirable. 



In mounting beetles, the pin should be thrust through 

 the middle of the right elytron, (wing cover), so that it will 

 come out on the under side between the second and third 

 pair of legs. After this, the limbs and antennae should be 

 placed in as natural a position as possible. (See Fig. 69.) 



Now make a gauge out of a little piece of wood with a 

 hole in one end about a quarter of an inch deep. This is 

 to keep the insect at a uniform distance from the head of 

 the pin, which is done by thrusting the head of the pin
