I have one or two slides that I wish to put on the screen. 

 (Fig. I-) 



This sHde is almost self-explanatory. The completely black 

 and the heavily-lined areas bordering the sea and bay coasts 

 represent the immense salt marshes ; the former is untouched 

 and the latter more or less completely drained for mosquito 

 control purposes. The lightly-lined areas indicated the territory 

 covered by the flight of the salt-marsh mosquitoes before any 

 diainage work was done. The dotted areas show the areas at 

 present covered by flights from the salt marsh, and the density 

 of the dotting indicates the severity of the infestation.

These figures represent the cost per county. You will notice 

 that Atlantic County starts in with an appropriation of $26,000', 

 Bergen with $18,000, Cape May with $10,000, and so on 

 down the list. The total amount of the annual appropriation is 

 $212,000. I want to call your attention to these two slides tO' 

 show in a graphic way what has been done and what we have 

 to do.
