NOTE.- The above illustration is a correct representation of the breeding of the 

 commonest of our domestic mosquitoes {Culex pipieiis). The story of one puddle is 

 the story of a million puddles. The sun may usually be depended upon to dry up the 

 ^reat majority of such puddles before 10 days elapse.
