DEAR BOYS AND GIRLS: I suppose you have all stood on the scales and been weighed. I have here a pair of balances. This was doubtless one of the earliest kind of instruments with which people weighed different things, and it is the kind of scales which are still used when the greatest accuracy is desired. These are called a balance, because when I hold them by this string you will see that this end of the arm and that end of the arm are equal in length and equal in weight and they exactly balance each other. Now when I place anything in the pan on this end of the arm, and place a small weight in the pan on the opposite arm, and then lift the balance up, you will see how I can readily tell how much the piece of metal, or piece of wood, or whatever I have placed in the balances, weighs. In the drug stores they use this kind of scales to weigh medicines, and they can tell accurately the weight of a very small quantity. In the laboratory, or the place where medicines are made, they have this kind of scales that will weigh the smallest particle of dust; even a small piece of a hair laid on the scales can be weighed accurately. In the fifth chapter of the Book of Daniel we read about a king whose name was Belshazzar, who lived in the great city of Babylon, surrounded by a great wall three hundred feet high and eighty feet broad, and with a hundred gates of brass, twenty-five gates on each side of the city, and a street running from each of the gates upon the one side, straight across the city to each of the corresponding gates upon the opposite side, a distance of some twelve or fifteen miles; and then other streets crossing these first twenty-five streets, running between the gates which were upon the other two sides of the city. God had blessed this king of Babylon and given him great wealth and great power; but he became proud and defied God. One night he made a great feast and invited a thousand of his lords and the generals of his army, and sent for the golden vessels of the Temple, which Nebuchadnezzar had brought down from Jerusalem, and Belshazzar drank wine out of these sacred vessels of the Temple. And, like men and women when they drink liquor, they lost their reason, and they praised the gods of gold, and of silver, and brass, and iron, and wood, and of stone, and thus dishonored God; and there appeared in the banqueting hall the fingers of a man's hand and wrote on the wall so that all might see and read it, and these were the words which were written before that wicked king: "Thou art weighed in the balances, and art found wanting." (Daniel v: 27.)
