 ms to Treatment-How the Pests
 Multiply.
 This is the season when, while brood
 ing peace is preparing to hover over va
 rious parts of the earth, down on Long
 Island the residents along part or the
 north some are getting ready to wage d
 war relentless and uncomproillSlnG, a
 war of extemination, in which no quar-
 ter is asked and none will be gwen, d
 war in which might well be the only
 right; to which every element that Scl-
 ence can contribute will be brought III assistance; a war in which no consider ation will be given to questions ot age or sex, and even the cradle Will De robbed-in fact, the more successfully the cradle is robbed, or even destroyed, the better satisfied will the warriors be-
 This is to be the annihilation of Mrs Culex and Mime. Anopheles, with all their kind, if the Long Islanders can carry out their plans, No more will the clinking song of c. Sollicitans con tribute to the evening entertainment or the north shore Never. again will the swinging and the zwunging ana the zwanging of Anopheles softly greet the strollers on the close-clipped lawns or the sitters on the unscreened plazzas.
 For. though the mosquitoes, like the Iocusts, the exceeding wise" of the prophet having no king, yet go torth all of them by bands" still shall ther wisdom be confounded and the places which know them now know them no more forever
 Tn the last two years considerable experiments have been made in some parts of the north shore of Long Island in the extermination of mosquitoes. Knowledge of the habits of these an moving and dangerous pests has spread so rapidly of late that it now seems certain that practical measures may be taken which will almost entirely free them from communities that have been so infested heretobefore as to be rem dered undesirable if indeed not impos- sible, as places of residence.
 Tn the summer of 1900 w. J. Matheson demonstrated on his place at Lloyd's Neck. on Cold Spring Harbor, that locality which had been the haunt Of swarnls of mosquitoes could be almost entirely freed from them by simple and inexpensive measures. Last year MT Matheson's example was followed by the dwellers on Centre Island, and al- though the circumstances were such that complete success could hardly be expected, nevertheless such satisfactory results were accomplished as to make it certain that entire immunity could be attained by further work.
 That stirred up the North Shore Im- provement Association, and through it's Executive Committee a survey was un- dertaken which has resulted in the for nation of plans for an active campaign all along the line this summer, from which great things are expected. The Executive Committee has just publish ed, in the form of small book, the re- ports of the engineers and entomolo- gists who made the survey, with the recommendations for the treatment of the many breeding places revealed by the examination
 This preliminary examination was made under the direction of Henry Clay Weeks, the engineer who, associated with Dr. l.. o. Howard chief of the di- vision of entomology of the United States Department of Agriculture, and
  mosquitoes, had charge of the work for MT Matheson and on Centre Island
 Prof. N. s. Shaler, dean of the Law renee scientific school of Harvard Uni i versity, great authority on salt ! marshes, was retained to make a spe- cial examination of such places in the territory under consideration, and | there were associated with MT. Weeks | ~,.Iz DrN ,Io no,y export, professor of entomology at the | University of Chicago, and F. F. Lutz, | an instructor in biology at the same in- | stitution.
 The territory examined is about sev- enty-flve square miles in extent, reach ing from the east shore of Cold Spring Harhor to Hampstead Harbor and from Lloyds Point to Roslyn and from Dosors Island to Cold Spring station, covering the entire north water shed between the east and west limits.
 Prof. Davenport and MT. Lutz walked over the entire territory and examined all the pools and streams, and even the artificial receptacles of water, which might be the breeding places of mos quitoes. When their detailed reports had been turned in to MT. Weeks the engineer and his assistants went over all the places indicated and examined them with a view to recommending to be taken to render them proof against the pest
 Accompanying the reports now pub lished Is map showing every such place found by the entomo1ogists and to the report Is detailed esti- mate of the work to be done at each place and the cost of 1t, with the time 1t will require. Where the work recom- mended cannot be done immediately it is proposed to petrolize the breeding places until the permanent relief work can be put through.
 The estimated cost of the proposed permanent relief work is S141000, and the amount of fuel oil used in petroliz- Ing places that cannot be improved im- until such work can be done would cost about $425.
 So much has been said and printed In the last two or three summers about Cluex sollicitans and Anophees that almost everybody ought to be scen- Iifically as wei as pestiferously ac- luainted with them. They are the only two the nine kindos of mosquitoes I That inhahit various narts of the Init | ,
