HOW MUCH DOES A POUND WEIGH? By W. A. DILL T H A T a "pound's a pound the world around," is true enough for all ordinary business transactions, but not for the Coast and Geodetic Survey. That department of the government has had a man in the Pacific Coast region for several months conducting experiments to determine exactly the variations that actually exist in the weight of a body at different altitudes. In computing these differences, the Survey man measures distances in terms of one ten-millionth of an inch, and time in one hundred-thousandths of a second. Speaking in broad terms, a mass that weighs 400 pounds at sea level will weigh, by spring balances, 399 pounds at an elevation of five miles. A mass weighing 400 pounds at the equator will weigh 402 pounds at the poles, since the poles are nearer the center of the earth than are points on the equator, and the poles are less affected by centrifugal force than are points on the equator. Besides these two large factors which affect the intensity of gravity, there are local causes, such as the presence of mountains, or of materials in the earth's crust of more or less the average density. Scientists have discovered that the greater the pull of gravity the slower a pendulum of a given size will swung, hence the relative intensity of gravity can be determined by comparing the rate of oscillation of a pendulum at different localities. The apparatus with which the experiment is conducted consists of the pendulum within its case, three chronometers, a small box containing an electric light with a shutter that can be made to flash a light with each second-beat of a chronometer, and a telescope for observ 403 ing light flashes as they are returned from the swinging pendulum. On the top of the pendulum is mounted a small mirror, and on the support of the pendulum is another similar mirror. These catch the flash of light from the lamp and reflect it back to the telescope. When the pendulum is exactly perpendicular, the reflected light from its mirror exactly coincides with the reflected light from the stationary mirror. The pendulum is known to have a period of slightly less than one second. The problem is to ascertain exactly the period of oscillation by observing the time which elapses between the moments at which the two reflected lights coincide exactly. When this time is determined, the time of a single oscillation can be computed readily. This simple computation, however, is far from being" the perfected work of the observer. Even though he has extended his observations over a period of half an hour, and has observed the coincidence of the lights four or five times, and has taken the average of the readings, he is far from that degree of accuracy for which he strives. In the first place, his $500 chronometer may not have been absolutely correct. If it were losing only four seconds a day, of course there would be a fraction of a second of loss in the six or seven minutes between the co-incidences of the lights that marked the location of the pendulum in a vertical position at a second-interval. To correct the time of the chronometer it is connected with the telegraph instruments as they are sending the "time" at noon, and the comparison of indentures made in a line on a revolving drum shows the variations from the true time as kept for the Pacific Coast by the master clock at Mare Island.
