62 COMPLETE INSTRUCTION IN 



line with the top of the case, and on a level with 

 the body of the miller. Then bring the tarlatan 

 over the left wing tightly. (Do not drag it over.) 

 Then hold it down with one finger while you 

 pass it over, and fasten down with paste the 

 other end of the tarlatan. Arrange the right 

 wing in the same way. See that the body is per- 

 fectly straight and natural. Arrange the head so 

 that the feelers will be in line with the wings and 

 yet in the proper curve. Take fine nippers and 

 draw the feet out so that at least two may be 

 seen more, if possible. If the wings have slipped 

 out of place, take a fine needle, and through the 

 tarlatan put them in place, and then hold them 

 there by sticking a naturalist's pin through the 

 upper part of the wing, fastening it to the case. 



All this work requires the greatest exactness 

 and care. When everything has been done as 

 directed, lay away the little cases in a shallow 

 box or on a large pasteboard to dry. This will 

 require a month or six weeks. Put some moth- 

 balls in amongst the cases, and beware of ants, 

 mice, or rats, for they will, if possible, get at them 

 and utterly destroy them. 



The cocoonery should always be provided with 

 a thermometer and barometer. A dish of salt 

 will in some measure answer the place of a 

 barometer, as if the salt shows much moisture, 

 the air should be dried.
