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

 of our domestic mosquitoes, {Culex pipiens). The story of one puddle is the story of 

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

 majority of such puddles before 10 days elapse.
