wide, I/* inch thick; two cleats 3^ inches wide by % inch by Vu 

 inch; one strip of cork linoleum a little less than 1 inch wide and 

 as long as the longest strips.

Ex. 53. Killing and Mounting Insects. 



Immediately after having caught the insect, put it in the killing 

 bottle and cork tightly. 



For mounting all insects except the butterfly and moth use the 

 insect box. Stick a steel pin (a sewing needle is better) through the 

 insect so that the insect is about */2 an inch from the point. Now 

 stick the needle about 14 inch into the cork at the bottom of the box. 



Write the name of the insect on a piece of white paper and fasten 

 near the pin. 



To use the spreading board, do as follows : 



Kill the moth or butterfly as before, and mount within half an 

 hour. Insert the pin, with the insect on it, into the cork just far 

 enough so the body of the insect will be in the space between the 

 boards up to the wings. Place the wings out flat on the board and 

 fasten them with narrow strips of paper held by pins. Arrange the 

 wings so that the rear margins of the front wings will just cover the 

 front margins of the rear wings and shall be at right angles to the 

 body. Now pin larger pieces of paper so as to hold all firmly until 

 dry.
