NATURAL REMEDIES. 113 



will require but little outside encouragement or renewal. 

 Dr. Lamborn brings one of the most interesting of these 

 natural methods forward to notice, and I have considered 

 it at length in the succeeding section upon remedies. 



It is also requisite to examine the divers conditions of 

 different places, and to adapt as far as possible remedies 

 most suitable, adequate, and attainable for the places 

 under consideration. 



Further, it is well to draw attention to the desirability 

 of a general and consolidated effort on the part of com- 

 munities in these enterprises, or even to enlist the assist- 

 ance of local governments towards securing some means 

 for the eradication of the pest. 



With these preliminary observations, and speaking 

 under the influence of a firm conviction that the mos- 

 quito is a serious and avoidable nuisance, I pass to the 

 consideration of the possible remedies.

The first measure which promises relief is the creation 

 of a sufficient number of the natural destroyers of the 

 mosquito ; that is, to set in motion an organic device, or 

 an arrangement of organic machinery, which will work 

 smoothly and effectively. 



This plan is fascinating in itself and is in accordance 

 with scientific principles, for it invokes the activity of Na- 

 ture to amend or repair her own mistakes and injuries, 

 and appears comprehensive and economical. It introduces 

 that balance of opposite agencies which Nature uses every- 

 where to repress her own.
