196 ELEMENTARY LESSONS ON INSECTS 



(c) Cut out bags of strong muslin, using a heavy wrapping- 

 paper pattern of the dimensions shown in the accom- 

 panying diagram. 



(d) Sew the bags, making a wide (1J") hem for a top- 

 band twice doubled to increase its strength. Close 

 the side below the top-band with a French seam. 



(e) Put the parts together, as 

 follows : 

 Insert the rim into the top- 

 band. 

 Bend the projecting ends so 

 that they will be parallel when 



crossed. 

 Wrap ends twice around at 

 crossing with a piece of soft 

 wire. 

 Insert ends of rim into holes in 

 handle. 

 Draw down wrapping wires tightly into the longi- 

 tudinal grooves of the handle, and wrap them 

 around the cross grooves and then twist them 

 together and tie them firmly in place. 

 Heavy water nets, having shallow bags of netting and 

 top-bands of duck, may be made after the same plan. 



2. Prepare screen cages (see figure 70 on page 197) by 

 cutting squares of wire cloth, hemming two edges together 

 and opening out to form cylinder, and then cross-folding one 

 end.

 tern for a (half) beating net (the 

 same as for an air net). Double 

 the cloth, lay this on it, and cut.
