nant water cut oflf by street and railroad constructions, tides restrained 

 and spreading over vast areas, and, worst of all, a public dump on a 

 marsh surrounded by nice residences, and in its midst houses of the 

 poor with water beneath and all about them — the entire water of the 

 section alive with larvae. See photos, between pages 66 and 67. 



Some Work and Its Results. 



Fifty-four barrels of fuel oil were sprayed by two (at times three) 

 petroliers, but no amount of such work could reach all these places. They 

 have all been reported on, and orders are issued by the Board. Under 

 the private fund, employing a large gang of laborers, several thousand 

 feet of ditching was run through all the places that could be engin- 

 eered, with the result that they were all dried out and all breeding 

 here was completely stopped in a large territory, with Gerritsen's mill 

 pond as a centre. Verbal and written testimony from several persons, 

 a number of whom had lived there for about twenty-five years, was 

 given of the fact that there were less mosquitoes in the section than ever 

 before, notwithstanding they were vastly more plentiful throughout the 

 country generally.
