Screening and Use of Papers, Foisons and Traps Are Good Only as Tenn porary Expedients-use of

Every fly that this year contamin, ates and destroys food or spreads i'll. ness is an enemy of America in even greater degree' than in the past. As a fly hunter, alluding to the tendency of the insect to spread disease. ex. pressed it recently, the fly is verit able "Gern-Hun." Every fly de stroyed means contribution, be i ever so slight, to the cause of Amer ica efficient.
 The best time to swat the fly, O course, is early in the breeding season before the young ones have become grandparents. Flies killed in the spring prevent hordes later on. But 1t Is q neyer-ending battle, and it late July and early August vigilance becomes more than ever necessary Work to kill flies even at this time may prevent abundant reproduction before cold weather. In fact, there is no closed season in hunting flies. A swat in any day of the year Is g meritorious swat, and even fly buzz. ing around window-pane in midwin. ter should be regarded as legitimate prey.
 Controlling the Ely.
 Careful screening of windows and doors during the summer months does not decrease the number of flies. but at least 1t lessens the danger of con- tamination of food. This applies not only to homes. but with equal force to stores, restaurants. bakeries, dai. ries, and every other place where food Is handled. Use of sticky fly papers to destroy flies that have gained ac- cess to houses also is well-knOwn, and fly-poison preparations are common.
 Many of the commercial fly poisons contain arsenic. and their use in. the household is attended by considerable danger. especially to children. This danger, according to specialists of the United States department Of agricul- ture, is lessened by the use of weak solution of formain. An effective fly poison is made by adding three tea spoonfuls of the commercial formalin to a pint of milk or water sweetened with little brown sugar.
 Flytraps may be used to advantage Their use has been advocated not only because of immediate results, but be- cause of the chances that the flies may be caught before they lay their first batch of eggs, thus reducing the num- bers of future generations. Many types of fly traps are on the market, and as rule the larger ones are ef- teetive. The United Stftes department of agriculture on request will send directions for making liytraps, not only for household use, but for catching flies and destroying eggs around sta bles and other breeding places.
 Preventive Measures.
 Fly papers, poisons and traps at best are only temporary expedienfS. The most logical method of abating the fly nuisance is the elimination or treatment of all breeding places. IL would appear, specialists say, from what Is known of the life history and habits of the common house fly that Ii is perfectly feasible for cities and towns to reduce the numbers of these annoying and dangerous insects so greatly as to render them of compara- lively slight account. Following are some recommendations of entomolo-
