TRAVEL IN THE AIR.

Man can go from one place to another on the surface of the earth in several ways. He can also travel over the water. But so far he hasn't been able to do much travel ling in the air, though 1t Is in the air that he will, and be has already made interest ing and significant progress in that direc- ton. Flying machines thst will work much better than Darius Greens inven- tion have been made, and ingenious and hopeful men are hard at work on others.
 The latest to come into notice is that of MT. Horatio Phillip., with which some successful experiments have been made in
 England. The machine is on an entirely new principle, being sustained in its flight by means of induced currents acting upon slats or lsths of wood arranged similarly to those of Venetian blind, in stead of the unwieldy plane to which designers of the flying machines have
 usually had recourse. Not but what MT.
 Phillips has used inclined planes, but he has reduced their dimensions step by step, un- til the transverse sectional area of one of his present sustainers measures only an inch and half in breadth by an eighth of an inch In thickness at the front, tsperipg to nothing at tho back. Broadly stated. the cross section of the slat is that of 8 knife blade, with 8 thick edge at back and @ thin one at front, and with the upper and under sides of the slat curved, but both differently. The form, in fact, is such that when the machine is in motion the convex upper surface near the front or thick edge defeots the air upwards, thus creating a partial vacuum on the up- | DOT face of the slat. The un- der or concaYe surface of the slat is formed to a parabolic curve, which gradually puts the particles of air into motion downwards, thus producing an e1- cess of pressure on the under side of the
 slat., It thus follows that upon forward motion being given to the machine the hor.
 izontal air-pressure which is brought upon
 the slats becomes converted, by reason oi
 the form of tLe slats, into an upward verti
 cal pressure which acts as lifting power
 and raises the machine into the afr. There
 are fifty of these sustainers or slats, eect
 II inches wide and go feet long. They ar, fitted Inches apart, and with their edgel
 horizontal, in frame 22 feet wide and
 feet inches high. They have combined
 area of lifting su,fsoe of 1s6 squar,
 feet, and they are carried in thei
 frame upon q carriage resembling
 . canoe 25 feet long and foot
 inches wide at the rear, but taperinl
 to a point at the front. Upon the car
 riage and near the sustainsrs are place | the engine and boiler and the air propelle,
 The engine is compound, having cylinder If inches and 8 inches in diamete, : respectively, with 6-inch stroke, an
 fitted with ordinary slide valves. Th I boiler is cylindrical vessel of phospho y bronze 12 inches In diameter and 1
 inches long. The propsller is twt ! bladed, feet In diameter and of fe, ; pitch, and Is driven at the rate of abe, !. 400 revolutions per minute The tot
