When these cases are shaken they produce sounds varying in intensity from loud to almost imperceptible sounds, according to the nature of the objects inside the cylinder. There is a double act of these, and the exercise consists, first, in the recognition of sounds of equal intensity, arranging the cylinders in pairs.

This papier-mache, which is also called a matrix, was baked hard by steam, put in a curved cylinder, melted lead was poured on it and there was a solid metal page of the paper ready for the great press, which was soon thundering away, printing thousands of papers, each one containing, on the front page, Larry's account of the interview with Sullivan.

On the ground with them lay a metal cylinder some two feet long and seven inches in diameter. There was also a coil of wire and a boxed magneto battery. One of the pair held to his eyes a pair of night marine glasses. Incessantly this watcher kept his gaze focused on Williamson. About two o'clock in the morning Williamson found it necessary to go below for a few moments.

I'm going to pump some of our air back into a cylinder to equalize our pressure don't want to waste any of it until we're sure the outside air suits us without treatment."

Compressed air was tried and abandoned. Tappets, cams, and eccentrics were all tried, to work the slide valve, to obtain the best results. The piston rod of engine passed through both ends of the cylinder, and with long connecting rods worked direct on the crank of the propellers. 'The diameter of cylinder of engine was 1 1/2 inch, length of stroke 3 inches.

The following illustration represents one of the three fast presses which the house of Hallberger employs in the printing of its illustrated journals. With the invention of the cylinder press by Frederick Koenig was verified the saying that the art of printing had lent wings to words.

He puzzled over this peculiar cylinder for some time and replaced it. Then he turned to the square apparatus and examined that. He opened a sort of lid and found one of the double cylinders within, and on the upper edge a little stud like the stud of an electric bell. He pressed this and a rapid clicking began and ceased.

These trunnions are generally placed about half way up on the sides of the cylinder; and through one of them steam is received from the boiler, while through the other the steam escapes to the condenser. The air pump is usually worked by means of a crank in the shaft, which crank moves the air pump bucket up and down as the shaft revolves.

Take this! Quickly! You are too large. Quickly!" Alan took a step. And sudden panic was on us both. Glora was here at our feet. We did not dare turn; hardly dared to move. To change position might have crushed her now that she had left her hiding place. My leg hit the top of the microscope cylinder. It rocked but did not fall. Where was Glora? In the gloom we could not see her. We were in a panic.

They lifted 'em out o' Flora's Temple reverent, but not wastin' time whilst I found out what had brought her down. One cylinder was misfirin'. I didn't stop to fix it. My Renzalaer will hold up on six. We've proved that. If her crew had relied on my guarantees, they'd have been half-way home by then, instead of takin' their seats with hangin' heads like they was ashamed.
