 drain a few old ponds, swamp holes | and the like and at a rough estimate | the cost would approximate $1,000 | only, says P. l.. ButteFick, expert on | who viewed the local situation and | reported to City Health Ohlcer, Dr. | Edward J. Brophy, Saturday.
 MT. Butterick's report follows:
 Norwich has no large mosquito problem. There are no large outlying | marches which require drainage: such 1 as surround most of the cities and l towns along the coast and large riv- CTS of the state. Mosquitoes do not descend upon Norwich in vast swarms and make life miserable for all the nhabitants-indeed many of the in- habitants scarcely realize that the city has any mosquito problem at all. Yet it has, for all that, dangerous Wich mosquitoes are Of the malarfal or disease bearing variety. Their bite is not especially painful-they attack their victims for the most part dur responsible for the rather large num- Der of malaria eases which are con- stantly being reported. Along with them breed the non- -malarial but far more annoying, common, fresh water mosquitoes. They cause much annoy ance to people living near their breed ing places.
 If Norwich has a less annoying but perhaas more dangerous mosquito problem than many communities, it 1 also has a problem much more easily solved than most. All that is required to solve the major part of the prob | lem is to fill or drain a few old ponds, swamp holes and the like. As a rough estimate the cost would ap- proximate $1,000 only.
 Breeding Places.
 The breeding places visited con prised only those whose location was known to the health officer. They ones in the city, although there re- mains the possibility of mosquitoes breeding in water barrels, cisterns, closet vaults, catch basins, clogged I1gutters old tin cans, and all sorts of miscellaneous water holding recepta- eles customarily found in cities. Such | places can be taken care of only by a frequent inspection of all premises l in the community by inspectors hay l ing authority to order and effect their immediate abatement. In con1nuni- I ties where the general sanitary con- ditions are poor, breeding in such places is often excessive.
 l Following is a discussion of various breeding places visited: The estimate of the cost of their eradication is only rough as it takes time and care to estimate accurately the cost of filling depression, lowering culverts, and the like.
 Small Swamp Near Spring Garden
 Avenue.
 This depression is said to dry en- tirely out in very dry weather, but while it contains water will always be a bad breeding place, both for common and malarial mosquitoes. Its abatement will be a simple matter All that is required is, first, to lower the outlet into sewer about two feet replacing the cap and vertical pipe with a horizontal pipe and a heavy wire guard to keep out large obstruc- tions; second, to make definite ditct , where partial filling has blocked the natural drainage and to place a cul. vert under the driveway which cuts across it in one place. The total cos
 should not exceed $50.
 Paper Mill Pond.
 So long as the water level of thi. pond is maintained at it's maximum } and it's water is not polluted it prob ably will never breed mosquitoes ex : cept casually in very small number.
