 on the creature's back four small pads, or pockets. 

 These are the first indications of the "grown up," 

 winged existence, and I wonder if they are not re- 

 garded by the young dragon-fly with something of 

 the same pride that a boy regards his first full set 

 of pockets. 



It is generally believed that it takes at least a 

 year and in some cases longer, for dragon-flies to

 must leave the water, and spend a few weeks in 

 the air. The transformation takes place during

 from May to September. Creeping from its watery

 a piece of rubbish. While shedding the nymph 

 skin and waiting for the wings to dry the creature

 to see that they are empty. Along the back of
