100 OUT OF BOOHS. 



Now let us turn a glance towards the little streamlet 

 caused by the drainage of the neighbouring fields, which 

 nas been quietly wending through its rushy path bj 

 our sides. Look steadily at every part of it, and the 

 water becomes as thickly peopled as the land and air. 

 On every side abundant living creatures are seen passing 

 through the waters, some slowly, others rapidly, while 

 many ascend from the bed of tlie stream, come for a 

 moment to the surface, and dive away out of sight. The 

 Water Boatman is very fond of that pmrsuit. A queer-

 and look at him nearer — only take care of fingers ; for 

 although the boatman cannot bite, he has a strong and

 captor by inflicting a rather painful wound. Under 

 his hard shelly wing-cases he has a beautiful pair of 

 large membranous wings ; and at nightfall he leaves the 

 water and takes to the air, mostly on some matrimonial 

 business. At dawn he returns to the water, letting

In the more rapid and clearer parts of the stream, 

 the Fresh- Water Shrimp may be seen driving itself 

 through the familiar element by a series of jerks ; now
