It is while we, ourseives, are dreaming in the sun by the margin of 

 some pond, that these swift children of the air seem but a natural part 

 of the dream. Yet if we 

 waken to note them more 

 closely, we find many things 

 very real to interest us. 

 First, they are truly children 

 of the sun, and if some cloud 

 throws its shadow on the 

 waters for some moments, 

 the dragon-flies disappear as 

 if they wore the invisible 

 cloak of the fairy tale. 

 Only a few of the common 

 species fly alike in shade and

sunshine, and early and late. 

 The best known of these is 

 the big, green skimmer, which does not care so much for ponds, but 

 darts over fields and even dashes into our houses, now and then. 

 Probably it is this species which has started all of the dragon-fly 

 slander, for it is full of curiosity, and will hold itself on wings whirring too 

 rapidly to even make a blur, while it examines our faces or inspects the 

 pictures or furniture or other objects which attract it. 



Another thing we may note when dreaming by 

 the pond is that the larger species of dragon-flies 

 keep to the higher regions above the water, while 

 the smaller species and the damsel-flies flit near its 

 surface. Well may the smaller species keep below 

 their fierce kindred, otherwise they would surely 

 be utilized to sate their hunger, for these insects are 

 well named dragons, and dragons do not stop to 

 inquire whether their victims are relatives or not. 

 It is when they are resting, that the dragon and 

 damsel-flies reveal their most noticeable differences. 

 The dragon-fly extends both wings as if in 'flight 

 while it basks in the sun or rests in the shadow. 

 There is a big, white-bodied species called the 

 whitetail which slants its wings forward and down 

 when it rests; but the damsel-flies fold their wings 

 together over the back when resting. The damsel- 

 flies have more brilliantly colored bodies than do 

 the dragon-flies, many of them being iridescent 

 green or coppery; they are more slender and 

 delicate in form. The damsel-fly has eyes which 

 are so placed on the sides of the head as to make 

 it look like a cross on the front of the body fastened 

 to the slender neck, and with an eye at the tip of 

 each arm. There are very many species of dragon 

 and damsel-flies, but they all have the same general habits. 



The dragon-fly nymphs are the ogres of the pond or stream. To any- 

 one unused to them and their ways in the aquarium, there is a surprise 

 in store, so ferocious are they in their attacks upon creatures twice
