One or two tears glittered on her long lashes when she at last fell into a light slumber, and the old pendulum's rusty voice croaking out: 'Give all take no thing' echoed hoarsely through her dreams like a harsh command which it was more or less difficult to obey.
As Gavin felt his way down the dark stair, awakening it into protest at every step, he had a glimpse of the pendulum's shadow running back and forward on the hearth; he started back from another shadow on the lobby wall, and then seeing it start too, knew it for his own.
He walked around for thirty seconds smelling the furniture, found a rag mat, settled himself down on it, and sat wagging his tail with a motion regular almost as a pendulum's. Tilda, observing it, heaved a small sigh, and perched herself on the packing-case, where she confronted Mr. Hucks fair and square across the table. "Now you just sit there and answer me," said Mr.
But notwithstanding all that the knowledge and skill of Huyghens could do, his most perfect instruments were still at the mercy of atmospheric changes. It has been said, that the time of a pendulum's vibration depends upon the length of its suspending-rod. This length is measured, not down to the bottom of the weight, but to the centre of its mass.
It was quite impossible to walk about, so I stood near the engines where it was warm, and amused myself with watching the pendulum, which was fixed opposite to me, swinging slowly backwards and forwards as the vessel rolled, and marking the angle she touched at each lurch. "That pendulum's wrong; it is not properly weighted," suddenly said a somewhat testy voice at my shoulder.
He was impatient, and Nature is profoundly imperturbable. We may adjust the beating of our hearts to her pendulum if we will and can, but we may be very sure that she will not change the pendulum's rate of going because our hearts are palpitating. He thought he had mastered yellow-fever.
It is this magical conversion of brass and iron into almost intelligent counters of the pendulum's vibrations, that the clock-maker effects by his beautiful mechanism. In the pendulum clock, the top of the swinging-rod is connected with a curved piece of steel, which dips its teeth-like ends on either hand into notches deeply cut in the edges of a brass wheel.
In these cases the plane of the pendulum's swing will indeed be shifted bodily, but the direction of swing will still continue to be from north to south. It is clear that if the earth is rotating about P O P' in the direction shown by the arrow, the rod a b is being shifted round, precisely as in the case first considered.
In wireless telegraphy it is absolutely necessary that the transmitter of the electro-magnetic waves should be brought into perfect harmony with the receiver without that condition it is impossible to communicate at a distance; again, a heavy pendulum or swing can, by a certain force, be pushed, say an inch, from its position of rest, and each successive push will augment the swing, but only on one condition, namely, that the force is applied in sympathy with the pendulum's mode of swing; if the length of the pendulum is 52 feet, the force must be applied only at the end of each eight seconds, as, although the pendulum at first is only moving one inch, it will take four seconds to traverse that one inch, the same as it would take to traverse 10 feet or more, and will not be back at the original position till the end of eight seconds; if the force is applied before that time the swing of the pendulum would be hindered instead of augmented.
The neighborhood never was so mislested with robbers since a neighborhood it has been. Why, sir, Mr. Morgan's new store, at Blackville was broke open and robbed of about twelve hundred dollars' worth of goods in one night." "And none of it recovered!" "No, sir. And, sir, Capping Pendulum's own house was entered and robbed of jewelry and plate to the tune of about two thousand dollars."
