See our conquest of the air dirigibles, aeroplanes, hydroplanes and the like. Yes! I see, and what of it? We have done, our advancement, our conquest, etc., etc. Yes! I see we have not lessened our arrogance, our empty-headed pride, our boasting. We Why "we"? What have you and I had to do with the new inventions in electricity or mechanics or the conquest of the air?

There is a never-wearying charm in these countless icebergs, so stately in size and so fantastic in shape and colouring. The fauna and flora of the country are so varied and exquisite that one wonders why the world of science has so largely passed us by. Perhaps with the advent of hydroplanes, Labrador will come to its own among the countries of the world.

Grimshaw knew little of hydroplanes, and the Interstate people had sent an expert demonstrator to the spot to teach their young exhibitor the ropes. Dave had been constantly under this man's tuition. It was far more easy, he had learned, to acquire a thorough knowledge, of how to run a hydroplane than to operate a monoplane.

Delhi might talk of a great flank march through Holland, with all the British submarines and hydroplanes and torpedo craft pouring up the Rhine in support of it; Viard might crave for brilliance with the motor bicycles, aeroplanes, and ski-men among the Swiss mountains, and a sudden swoop upon Vienna; the thing was to listen and wait for the other side to begin experimenting.

This works out to give automatic trim on a substantially level keel, and I have known of vessels running for a period of two hours without variation of depth of one foot and without once changing the inclination of either the hydroplanes or the horizontal rudder. A great deal of skepticism was displayed for many years towards this new system of controlling the depth of submergence.

HYDROPLANES. Hydro means water, hence the term hydroplane has been given to machines which have suitable pontoons or boats, so they may alight or initiate flight from water.

These hydroplanes were located at equal distances forward and aft of the center of gravity and buoyancy of the vessel when in the submerged condition, so as not to disturb the vessel when the planes were inclined down or up to cause the vessel to submerge or rise when under way.

A third will probably lead to a retirement of the battle fleet to some east coast harbour, a refuge liable to aeroplanes, or to the west coast of Ireland and the real naval war, which, as I have argued in an earlier chapter, will be a war of destroyers, submarines and hydroplanes, will begin.

The Reliance made a beautiful run, and he felicitated himself that he had got onto the knack of running it right. "I don't believe much in hydroplanes," old Grimshaw observed to him as he accompanied Dave back to the aero grounds, "but I believe in you, and I will say you made a clever showing." "Wait till the Interstate folks send on their latest improved aero-hydroplane, Mr.

That is to say, the rudder guides it and changes the angle of the boat. But the hydroplanes pull it up and down, two pairs of them set fore and aft of the centre of gravity. They lift or lower the boat bodily on an even keel, not by plunging and diving.
