box; by that time they will have completed their life 

 work and death will soon come to them naturally. 



In setting up a lepidopter, after making sure that it is 

 dead, thrust the pin through the thorax, setting the 

 insect well up toward the top of the pin ; then set the pin 

 with the insect on it in the trough of the drying-board, 

 to such a depth that the wings lie on the sides of the 

 board at a slight angle with the plane of the body, say 

 25°. Carefully spread the wings, front and hind wings 

 on both sides of the body, in order to display the veins 

 and color markings. If the trough is too wide to allow 

 the weighting of the wings after they are stretched, put 

 a piece of stiff paper or card board on the board under the 

 wings and stretch the wings on this. Care must be 

 taken not to break off the legs of the lepidopters, and the 

 antennae must also be carefully preserved.
