The pen is thus controlled by the combined movement of the four pendulums, and this movement is registered on a drawing board by the pen. There is no limit, theoretically, to the number of pendulums that can be combined in this manner.
This alternation is repeated over and over again, until all the energy of both pendulums is exhausted. To make the experiment more attractive, we substitute for the simplest possible pendulums weights at the end of strings small swings, each containing a figure sitting or standing on a seat, to the underside of which is attached a quarter of a pound of lead. Eighteen inches is a good length.
He did not say a word, but went straight up to his burro. He saddled it in silence, strapped his old guitar on its back and, swinging himself into the saddle, dashed off across the alkali, his long legs working like pendulums on either side of the little creature. It actually seemed as if he were propelling instead of riding it.
If, after the first undulation in one direction, another occurs in the opposite, the pendulum facing the first will in its turn begin to move; and if other undulations make themselves felt in diametrically opposite directions, the other pendulums will begin to act.
Assuming that the length of the deflector is kept constant and in practice this is found to be convenient the ratios can be altered by altering the weights of one or both pendulums and by adjustment of the upper weight. For the upper harmonies, 1:4 down to 3:8, the two pendulums may be almost equally weighted, the top one somewhat more heavily than the other.
On my way home to lunch I glanced at the clock in the church tower and saw that it was an hour ahead of time, having been made to coincide with Teuton pendulums. This is the second time that it has happened, for the villagers dared to climb up the long stairs and put it back, once, but the soldiers were so ferocious in their threats that well, one must accept their insolence.
These, though they confirm the foregoing results, give a somewhat greater ellipticity to the earth than that found by the measurement of degrees. Pendulums vibrate more slowly the nearer they are to the equator. It follows, therefore, that they are there farther from the centre of the earth.
They entered a loft, open to the peak and shingles, with a window in each end. Clocks, dials, pendulums, and tiny cog-wheels of wood and brass were on a long bench by the street window. Thereon, also, were a vice and tools. The room was cleanly, with a crude homelikeness about it. Chromos and illustrated papers had been pasted on the rough, board walls.
Thus, Nothing so vulgar as to be in a hurry. True, but hard of application. People with short legs step quickly, because legs are pendulums, and swing more times in a minute the shorter they are. Generally a natural rhythm runs through the whole organization: quick pulse, fast breathing, hasty speech, rapid trains of thought, excitable temper.
They had on the air ship ingenious clocks, driven by weights, and governed by pendulums, but the divisions of time were unlike ours, and there was nothing corresponding to our days. This, of course, arose from the fact that there was never any night, and, being unable to see either sun or stars, they had no measure of the year. With them time was simply endless duration, with no return in cycles.
