ward the amelioration of a long-suffering public from a most noxious pest. 

 My services have been given to the cause with the hope that outdoor life 

 in summer might be made as enjoyable here as it is in many towns where 

 the mosquito is unknown, and with the many natural advantages of water- 

 front and railroads, our city might become, not only a greater residential 

 suburb of New York, but develop a manufacturing industry second to none 

 in the State. WM. F. ROBINSON.

Having- in hand the reports of what has been done, it will 

 be interesting to read Mr. Brehme's report of the investigations 

 made by him from time to time for the three summers last past : 



The area between Bound Creek and Woodruff Creek and the 

 high ground and Pennsylvania Railroad is of considerable ex- 

 tent and looks like a very dangerous piece of ground. Indeed 

 it becomes dangerous at times during the summer when the 

 tides run low and none rise high enough to stock the pools. The 

 early spring tides overflow the banks of both Bound and Wood- 

 ruff Creeks and with these high tides killies come over and are 

 left in the tide filled pools as the water recedes. Several inspect- 

 ions of the area were made and no larvae were ever found until 

 midsummer after a spell of dry weather had dried up all the 

 pools and killed the fish which had been left there in spring". 

 After the first heavy shower subsequent to this drying out the 

 pools became water filled and, no fish being then present, the 

 larvae of the mosquitoes have everything their own way and 

 swarm everywhere. There are many old ditches on this meadow 

 which would be very useful if they were cleaned out and there 

 are two large creeks — Bound and Woodruff — which have good 

 banks and sufficient depth to take any ditches which it might be 

 necessary to run into them. In a favorable season both Eliza- 

 beth and Newark get a very nice supply of mosquitoes from this 

 territory. 



The next point is the area between Woodruff Creek and the 

 Central Railroad east and west, and Grand Island and Bound 

 Creek, north and south. This place has a number of breeding- 

 pools which can be abolished by cutting ditches into Bound and 

 Woodruff Creeks. There are many large ponds and pools on 

 this stretch ; but all are stocked with fish. Old ditches cut many 

 years ago run to these ponds and pools. They would be work- 

 ing to-day were the railroad ditches not filled. Some eight or 

 ten years ago an enormous flood tide swept in from Newark 

 Bay across the Central Railroad bed and washed out the em- 

 bankment, filling the ditches with stones, cinders and other de- 

 bris. The roalroad rebuilt its embankment with new material 

 and left the old where the water placed it. The ditches were 

 never reopened and the natural drainage of this meadow area
