ening the banks and so regulating their 1 courses that there will be no pools of
 stagnant or slowly moving water. In
 some cases this work would have to be
 supplemented by ditching.
 In the springs, the subject of the
 fourth proposition, the breeding of
 mosquitoes can usually be corrected by
 confining the spring to definite banks, l which is not a work of difficulty,
 Springy areas should be drained or fill-
 ed.
 Ponds and bodies of water which can
 not be drained or filled, the subject of the fifth proposition, offer more difficult | ty, and approach the salt marshes in the expense and trouble of correction. | The breeding will be greatly reduced, if
 not prevented, by making the edges of the pond regular and freeing them from vegetation so that there are no accumu- | lations of water so shallow that they are not accessible to fish
 The maintenance of certain kind of fish, such as goldfish sunfish, stickle- backs and top minnows in ponds so treated would probably entirely prevent breeding, or at least prevent them from breeding to any serious extent, Where no other treatment is possible relief can be had by the periodical use of pe- troleum spread upon the surface of a thin layer. This serves to smother the larvae
 The sixth recommendation concerns the breeding of mosquitoes in rain barrels, cisterns and tanks If can be prevented tt-r tr,f { hn holders and vigilance on the part of the public authorities.
 Barrels and tanks should be kept cov- cred and the water drawn from the bottom by means of spigots. Cisterns should be kept tightly covered and a few fish kept in them.
 Cesspools, drains and catch basins, the subject of the las recommendation; should be kept tightly coVsred, and pe- troleum should be used also, In all cases such as there the coverings should be very tight, for the willy mosquito will crawl through very small open ing. and the mischief is soon done. Clouds of mosquitoes have been seen coming from the top of 2 gutter pipe leading to a cistern that was tightly closed.
 These are the things the north shore residents are going to undertake this summer. They are already at it, and since the first thaw of the spring they have been watching for possible breed ing places,
 The inspection of the territory by the entomologists and engineers involved walking and driving more than thou sand miles Most of 1t was done on foot. Tn the villages house-to-house inspection was made to disclose the ar- tificial breeding places.
 When the larvae could not be directly observed the entomologists used little net made of cheese-cloth about the size of a mans hand and a large spoon. They poked into every place that look ed as if it might harbor the pests, and even examined the water left standing in the footprints of animals in the fields.
 Town authorities and health officers aided by appointing the specialists as inspectors, and in all the examinations in the different lines there was but lit- tie opposition, though one of the en- was atferward described to
  looking into rain-barrels expecting to find mosquitoes there. Some of the worst places will require such treat 1 ment that special legisla tion will be necessary to provide the authority and in some cases part at least of the means.
 The most difficult problem found by the engineers and entomologists was al Glen Cove. There are salt marsh, with an area of about forty acres, twc un- used mill-ponds and some streams.
 The two ponds present the specially | difficult feature, the marsh work re- quired being such that it could be done l for few hundred of dollars unles it 1 were desired to reclaim entirely the l whole marsh, which would be an exten | 5ive as well as expensive undertaking. 1
 The treatment of the ponds proposed | was draining, and the engineer sug- gested that a boulevard be constructed . dong the centre line of the two ponds with sewer at each side. This would 1e a great Improvement in the town. It would add much valuable property.
 Facing the boulevard on both sides
