Herald Mr. Edison reasons thus i—Because a bee cannot carry a weight equal to it own on its back, t therefore a flying machine made on its model cannot possibly support any more than its own weight no matter how much tho power be increased, . Now it is quite reasonable to argue that if the bee can carry tho weight in any other way—with its legs—for instance, the conclusion is not correct. The ordinary working bee can carry the body of a dead drone out of the hive, holding the weight with its legs, and fly with it to a considerable distance. To perform this feat it exerts double its ordinary power, the speed of vibration of the wino-s being increased from 130 to 190 per second. J. he rate is ascertained by the musical note produced by the vibrations. It is not necessary to take either the bee or a bird for a model, and the problem is very far, indeed, from being a puzzle, the the real puzzle being how to find some one with enterprise enough to make the test. . If Mr. Edison will only turn his attention to this interesting subject for a little while his great genius will surely hasten the day of success, not necessarily by un- bOiUSftiidenffitte, weighing idgftthefonly thitteehpotifids,>nd'they exerted ft force of one nofse power.

Many years ago a very interesting ex- >eriment was made at the Novelty iron works, The machine employed supported itself in the air, but its action was unsteady because the power developed by the boiler was irregular owing to the employ- mehtof coal for fuel. Every time the furnace door was opened the steam pressure dropped. Had the experimenters known how to use the petroleum fuel a perfectly steady and a mucn higher pressure might have been maintained automatically and the conclusion then reached that "with th nmns available flight was impracticable' would have been Very different.

Observation of nature teaches that the mam essential for successful flight is a suitable motor. This is confirmed by the experiments of the London Aeronautical society and otbers, whose conclusions may be thub stated: . Flight will be attained when a machine is built that is light enough and powerful enough to lift ihs own weight by the aid ot wings or their equivalent, and to hold it suspended agauist the force of gravity lne« have also fully demonstrated that one horse power applied to a screw propeller on a vertical axis will cause it to lift and hold suspended a weignt of thirty-six pounds, and that for every ho'rse power so applied an additional thirty-six pounds will be htted. TESTS FOR LIFTING POWER. Dr. Fomingo', of Copenhagen, made tests of the thru.st or lifting power of a propellor wheel and found, that it utilized M per cent, of the energy imparted to it. It was 1 foot in diameter, 1 foot pitch, 1-7 square foot aiea of blades and 7-20 oound weight. It was held on a pulley by pins ;hat could be detached instantly, the axis being vertical. The pulleys carrying the propellor wheel was caused to revolve rapidly and when a good speed was ob- amed and the wheel was liberated it irose in the air by means of the energy rnnnrl tv. iJ- °~ horse power to lift it, and as a man can exert but one-fifI hy horse power it follows that he can lift but one-twentieth of his device can THE high school building at Pekin, Til'., a large throe story structure; was. en- toredm it. At 13 revolutions per second it hovered , it had just lifted its own weight. At 5^ revolutions per second the upw'ard thrust was 6 pounds, and Jthe energy required to maintain this thrust was about 10U foot pounds, This is equal to about pounds lifted per horse power. O When released, the speed being 70 rev plutions per second, it arose to : height of over 200 feet in less than on second. When the wheel was preventec Jrom rising and made to revolve 52 times per second the thrust was six pounds, bu the efficiency was not so high as when i wasi free to ascend. Efficiency is mucl higher when the propellor moves itself through the air than when its power is spent in moving the air, producing nn air current of a fan or blower. Carl Vogt from whose paper on air propellers—read before the royal society—the particulars of this experiment have been taken, says that the efficiency when moving itself was 70 pur cent, and when acting- as a blower moving air, it was only 35 per cent. In the thrust was SS pounds per when moving itself the , . - - —o ~ of wing action and efficiency, only what has been demonstrated experimentally and with propeller wheels need be considered. Flight by means of wings operated by power is probably more economical and simple, but as that has not yet been demonstrated we shall not adopt it in our proposed full size machine. MATHEMATICS OF THE SUBJECT. The speed of revolution in the small two wheeled machine mentioned above, 52 per second—3,129 per minute, would be quite impracticable in a larger one, to carry— 10,000 pounds. It must be reduced to what is attainable by steam engines connected directly to the crank shafts, say about four hundred and fifty revolutions per minuS? J.O keep within reasonable limits in this sketch, only the method of determining the particulars can be given, and even then only roughly. Remembering that lifting power is proportioned to the square of the speed of revolution and to tho fourth power of the diameter at the same speed of revolution t will be found that the small two wheeled machine can lift only .748 pounds at 450 evolutions per minute, and that the two wheels of a machine to lift 10,000 pounds nust each be 13 feet 6 inches in diameter t they be made to revolve at the same peed. Only the minimum lifting power of 36 ounds per horse power, the Aeronauti- fll bociety s standard, has been taken In experiments made in September ctober and November, 1887, by Messrs Jamstroin and Lohinan, engineers, Copen agen. an air propeller applied to a boa gave 10 pounds thrust per 100 foot pound ettort, equal to 55 pounds thrust or liftinL power per horse power. On this basis two Id toot 6 inch wheels, revolving 450 times per minute, will lift 15,290 pounds and require 278 horse power.

WEIOHTS PER HORSE POWER. If a propdV, with engine and boiler to operate it and apparatus to connect them, can be built, the whole weighing less than thirty-three pounds per horse power, it should be able to ascend in the air like Dr Eremnges'propeller wheel. Motive power machinery is seldom made so light, not because that is a difficult matter, but because it would be too costly in the cases where it might bo employed. The lightest machinery in proportion to its power of which there are examples in operation is iu torpedo boats, ana their boilers, engines, pumps, condensers and blowers all told weigh cnlv sixty-six pounds per horse power. The ref- ative weight is much less than this in some of them. But for special purposes weight per horse power has been greatly reduced. The torpedo boat's machinery mie-ht be very much lighter if water tube boilers were substituted for those of the locomotive type generally employed.

The whole machine might be made very much lighter, as no ingenuity has been exercised in saving weight, but it would be more costly. We have seen that the power and weight of both motors and propellers have been ascertained by competent persons, and the expenditures of a small sum of money to test the truth ot their assertions would put doubts forever out ot the question. A boiler and engine need not be built for this purpose as, their weight and power can be determined from drawings with sufficient accuracy. The important matter on which all the rest depend is the thrust of the propellers per horse power. This should be found for three or four different diameters with changes of speed, pitch and surface' in order to determine ratios of increase but chiefly to help the sceptical with reliable knowledge.
