Heat caused the glaciers of the Alps to melt and move at an alarming speed, while lakes in Switzerland dried up, exposing their bottoms and showing foundations of the homes of the lake-dwellers living there thousands of years ago. While the sun is the nearest of the stars, the moon is the nearest of the heavenly bodies. It is about two hundred and forty thousand miles from the earth and has a diameter of about twenty-two hundred miles, or about one-quarter that of the earth. The moon, accompanying the earth in its movement around the sun, rotates on its axis once in twenty-nine and a half days and moves in a small orbit, once in twenty-seven and a third days, around the earth at a speed of nearly twenty-three hundred miles per hour. The moon shines merely by reflected light from the sun, whose light is six hundred thousand times brighter than that of the moon. The moon has a temperature of two hundred degrees below zero, Fahrenheit. The surface of the moon structure, for the most part, is extremely broken. There are hills or mountains, but the surface is pitted all over with great “craters,” ranging from fifty to one hundred miles in diameter; there being a few with a diameter of more than one thousand miles. A counterpart of this is hardly to be found on our earth, yet it is believed that the moon was once part of this earth, becoming separated from the parent body by the tremendous centrifugal force of the earth; as it is likewise assumed that Jupiter will in time throw off its “great red spot” thus forming a new moon of Jupiter. It is believed that the planet Mars, which has two moons, is inhabited and that it has great irrigation canals, which engineers say are far superior to any irrigation system on earth. During the last sun spot period wireless signals were supposed to have been received from Mars. From time to time, bodies very different from the stars and planets appear in the heavens, remaining visible for some weeks or months and then vanish in the distance. These are the comets. The larger ones are magnificent objects, sometimes as bright as Venus and visible by day, with a head as large as the moon and having a train or tail extending behind it from the horizon to the zenith and which is in reality long enough to reach from the earth to the sun.
