In going up this easy and perfectly smooth ascent for some six or seven miles, the disadvantage of having no intermediate-speed gears was forcibly illustrated, for the grade was just too stiff for the high-speed gear, and yet so easy that the engine tended to race on the low, but we had to make the entire ascent on the hill-climbing gear at a rate of about four or five miles an hour; an intermediate-gear would have carried us up at twelve or fifteen miles per hour.
The "Dolphin," of fifteen hundred tons displacement and a speed of fifteen knots, was designed as an auxiliary in naval operations, and it was expected that she would furnish a model for high-speed commerce-destroyers to be subsequently built. These vessels were constructed at an aggregate cost of over $2,400,000, in the shipyard of John Roach, of Chester, Pa. The "Dolphin" was launched in 1884.
He drew down the corners of his mouth till he looked a cross between a music-hall comedian and a sick child. 'If you were looking for something in the root of the hedge, you wouldn't want to scour the road in a high-speed automobile. And still less would you want to get a bird's-eye view in an aeroplane. That parable about fits my case.
"Yes, sir," replied both lads. "Very well. The solution of this mystery is, primarily, motorboats." "What do you mean, sir?" exclaimed Jack. "Just what I say. In the main, the possible hundred German submarines that have disappeared recently have been accounted for by high-speed, powerfully armed motorboats.
The centrifugal pump was direct-connected to a vertical high-speed engine, and the coupling is shown at E in the elevation. Every possible plan was contemplated to accommodate the engine and pump without removing any of the columns, and the arrangement shown was finally adopted, leaving the column P in its former place by employing an S-connection from the pump to the condenser.
Explaining this to Zarlah, we hurried to the villa, and, as we ascended the steps to the balcony, I beheld a large high-speed aerenoid resting a short distance from mine. This, Zarlah begged me to take, explaining that by rising a few hundred feet above the elevation of small aerenoids, I could safely exceed the customary speed of local traffic.
Their displacements ranged from 17,250 to 28,000 tons, and their speeds from 25 to 30 knots, the last being that of the Tiger. Their speed is their greatest feature, for their armament and batteries are much lighter than those of the first-line ships. Next, there were ready thirty-four high-speed cruisers of quite light armament and armor.
Sixth To design efficient dynamos, such not being in existence at the time, that would convert economically the steam-power of high-speed engines into electrical energy, together with means for connecting and disconnecting them with the exterior consumption circuits; means for regulating, equalizing their loads, and adjusting the number of dynamos to be used according to the fluctuating demands on the central station.
He was some kind of a man, to begin with, and had an excellent brain and the worst manners conceivable. He contradicted everything you said, and looked out for an argument as other people look for their dinner. He was a double-engined, high-speed pacificist, because he was the kind of cantankerous fellow who must always be in a minority.
Soon the strange craft was again dimly visible, appearing like a gray blot in the darkness ahead. Off the Hell-Hole she turned shoreward and was lost to view. "Tell him to stop the motor for a moment," whispered Dickie Lang. When Bronson complied, the silence for the space of a few minutes was unbroken. Then from the little cove came the muffled cough of a high-speed motor. "All right. Head out."
