Niglit insjjectioiis were continued ]\r:iy KJtli and iTth, and only 

 isolated examples of cantator were seen. People were sitting out 

 everywhere, in coinfort, and no one was fighting moslpiitoes. 



May 26th, the marsh was found dry, free from mosquito-breed- 

 ing places, and even on the Ebeling tract Mr. E.rhard had little 

 trouble in killing olf the small brood that hatched there. Then 

 came a two-days rain, measuring 3.16 inches, and the marsh was 

 again examined May 29th. Everything was covered with water, 

 but the ditches were working properly, and on the 31st all the 

 water was gone except in a fcAv places, where so little remained that 

 its disappearance w-as a matter of hours only. 



There was a very high tide June 12th, and on the 13th it was 

 found that the Hamburg Place area had been covered, bringing 

 up "killies" everywhere ; the ditches were working properly and 

 Mr. Erhard was removing such driftage as was likely to obstruct 

 the free outflow of water. All the other areas were already drained 

 clear and no pools remained. 



June 18th, a city inspection was made over areas where pipiens 

 had been known to breed and it was found that the local board had 

 done good work, oiling some places and filling others with earth 

 or ashes, so as to dispose of them finally. 



A period of high tides being in progress, the meadow was 

 visited June 19th, and found to lie water-soaked, with all depress- 

 ings full of water, only a few of them with "killies.'' June 24th, 

 the meadow was again dry except on the Ebeling tract, on which 

 there was quite some water containing scattering larvge. A few 

 of these developed into adults before the water was all off, but 

 none developed elsewhere on the meadow. 



June 27th, the Bloomfield area was again visited and eighteen 

 larvae were found after the closest kind of collecting. These were 

 C. terriians, 12; C. sylvestris, 3; Psorophora cilmia, 1; Ano- 

 pheles sp., 2. An inspection of Branch Brook Park was made 

 during the same day and larvas were found in some of the catch 

 basins. The secretary of the commission was notified and there- 

 after these places were regularly oiled and no breeding was per- 

 mitted. 



July 3d, the fourth marsh brood was on the undrained meadows 

 and the Newark areas were visited to see to what extent it was 

 represented. Only on the Ebeling tract was any breeding going 

 on, and even that was so scattering that little could be determined.
