breeding they find, but to report their findings to the Deputy 

 Chief, who then verifies their reports. The discipline in refer- 

 ence to the negligence on the part of the inspection force to find 

 breeding cannot be too rigidly enforced, and this negligence in 

 our department calls for a reprimand for the ifiirst offense, sus- 

 pension for the second, and dismissal for the third. 



It should be the effort of the department to get all depres- 

 sions, which hold water long enough to breed mosquitoes, filled 

 in or drained as quickly as possible, thus avoiding* the expense 

 of frequent oiling. I do not mean by this that the department 

 should keep up a constant annoyance of those individuals who 

 happen to own such property, but that the inspectors should at 

 all times be on the lookout for filling material such as street 

 sweepings, cellar excavation earth and winter garbage which 

 should average 85 per cent, ashes. This material usually can 

 be had for the asking, and our department will assign a 

 laborer to level it off. The cost of abolishing breeding places in 

 this manner will be no greater than to take up the time of the 

 department with correspondence, interviews and court proceed- 

 ings to abate the nuisance, and should make more friends for 

 the work. There will be some property owners who look with 

 disfavor upon any effort being made to abolish breeding 

 nuisances on their property, and in such cases, if persuasive 

 methods are of no avail, it becomes necessary to resort to the 

 courts for relief. 



The office should keep informed during the breeding season 

 as to the conditions, and this can be done by a series of night 

 collections made biweekly of adult mosquitoes. This will show 

 to what extent as well as the varieties of mosquitoes on the wing. 

 These night collections prove interesting, show the direction of 

 flight and frequently lead the way to the breeding ground. 



The nature of the work is such that nothing should be taken 

 for granted. When an inspector finds breeding on a premises 

 he should use every effort to get rid of it before leaving. I 

 recall instances where an inspector has left a barrel containing 

 breeding for the householder to empty, and returning several
