right side up while the wheel revolves around it. This is accomplished by means of rollers in contact with the inside of the rim. SIXTY-SEVEN WOULD NOT POSE Skunks do not like daylight so Irving June of Stamford, Connecticut, had his picture taken with eight which would come out. SEVENTY-FIVE MILES AN HOUR ON ONE WHEEL The new machine has a record which the inventor hopes to greatly exceed when he finishes work on mechanical details. In addition to the pas senger, this frame supports the engine, fuel oil, and batteries, and also a steering wheel for the driver. The wheel is of aluminum, with a diameter of eighty-one inches, and is equipped with a solid rubber tire. Skids, carrying rollers, project at the sides to keep the machine upright while it is at rest, and when in motion the momentum keeps it upright, like a rolling hoop. It is believed there is practically no limit to the speed which may be obtained with further development of the engine, and a race between a couple of these one-wheel whirlwinds should afford a most exciting contest. The unicycle could be equipped with a much more powerful engine. The chief change in construction in consequence would be in balance, which could easily be adjusted. Tremendous speed might then be developed without greatly increasing the danger. This great shear is capable of cutting six and a half inch bars as easily as ordinary scissors cut thin materials. Cleveland practically a flyless city? The following question and answer from the official Fly Catechism contains the philosophy of the whole thing in a nutshell: "How many flies may breed from a pair in the spring?" "Allowing six batches of eggs of one hundred fifty each, supposing all to live and find filth to breed in, the number would be 191,010,000,000,000,000,000, enough to bury the entire earth fortyseven feet deep. Why not kill the fly in the winter or early spring?" been generaled by Dr. Jean Dawson, professor of civic biology in the Normal School. She has the assistance of the "junior sanitary police"-boys recruited from the seventh and eighth grades of the city schools. The principal of each school appoints the force for his district, and it is considered high honor in Cleveland to be made a "fly cop". For each school a chief, assistant chief, and four inspectors are chosen to officer the squad. During the winter, the amateur policemen go after the winter flies, sellSo instead of the old slogan, "Swat ing them to Dr. Dawson by the tens the Fly", the war-cry, "Head 'em Off", of thousands. Then as spring warms was adopted, and during the last three up the old heaps of lawn clippings, rubwinters the war has been fierce and bish, and fertilizer-all excellent breedtriumphant.

He must From the first the movement has make regular inspections. When he discovers an offense, what happens may be something like this: "Mrs. Smith," the small officer says to the lady at the back door, "I am a member of the junior sanitary police. Your garbage can has no cover and I am afraid you will find it a good breeding place for flies." Most Mrs. Smiths have read the newspapers and know something of the junior sanitary police. But suppose this one to be unfamiliar with the methods of the fly fighters, and both cantankerous and busy. "Mind your own affairs!" she snaps. "I imagine I can look after my own garbage can! Such impudence!" and the door slams. The "fly cop" refers his case to his senior officer, the boy inspector. This high official tries his wiles upon the irascible housewife. If he also fails the matter goes on up to the boy chief, who writes some such note as this: My dear Mrs. Smith: We are trying to make our school district flyless. Will you help us? Flies breed in ferment ing lawn clippings, us. Very truly yours, open garbage can is not corrected. Thus the city backs up the authority of the junior sanitary police. A cover is found for that garbage can! The whole process, from the first warning to the final correction, has probably not taken more than five days. Generally, of course, such drastic measures are not necessary. The first visit of the "fly cop" is usually sufficient, because householders are naturally not averse to being free of flies and are willing and eager to do their part toward this end. That ninety per cent of the house flies are bred in unclean stables is the claim of Miss Dawson. Stable owners have been put through a course of education that has been as effective as it has been novel. Pretty college girls have been paying visits to stable men and showing them how to clean house. The girls are recompensed from a special fund granted by the city council. Stables have become clean as if by magic and most of them are staying clean, for the girls happen in every so often to see how their suggestions are being carried out. Chief of the Junior Sanitary Police. It is hardly conceivable that Mrs. Smith could still remain obdurate. But if she does, the case is reported by letter to the Street Cleaning Department. Mrs. Smith is startled one morning to receive an official-looking document from the City of Cleveland threatening immediate suit, if the offense of the Hosts of smaller girls, members of the sixth, seventh, and eighth grades, are made "sanitary aides". Their duty is to inspect the city's stores. A HOW THE MERCHANTS OF ONE DISTRICT little girl steps into a meat shop or candy store and notes down on a specially prepared blank the number of flies she can detect in three minutes. The blank goes to her chief, and a day or so later the merchant receives courteous official notification as to just how his store compares with others in the same class. If it compares well, he is congratulated. If it |
