StJGGESTlONS FOE DECOYING BUTTERFLIES.

two arms, giving just a slight curve in the opposite direction 

 towards the extreme tips ; the spring may then be perforated for 

 the thread B, as shown in the figure. But as this perforating, 

 though certainly the best and most workman-like job, is difficult 



to do even by the aid of heat, another and easier plan will be 

 suggested further on. The spring may now be slipped, at its 

 middle, under the shorter spring, G. 



Thirdly. — Cut two pieces of card, A A, Fig. 3, larger than the 

 expanded wings (to be afterwards trimmed off when the latter 

 have been attached) , thus affording more protection from damage 

 to the decoy than if the cards had been cut smaller. Next cut 

 out, and bend to the shape indicated, three pieces of card, Da, 

 E, and F, and glue them firmly together, as shown in Fig. 3, 

 leaving a space at G, through which the bent spring (D, Figs. 1 



er\Yo,^ WIA 



and 2) has to pass ; then hinge the pieces A A to D by means of 

 a strip of linen or tape B, as shown at A a, Ba, Da, in Fig. 3 ; 

 but this must be so managed that the wing pieces have free 

 movement upwards and downwards.
