Suppose one of the girls here goes to the store to buy a piece of cloth. How does she tell the merchant how much cloth she wants? She, without doubt, will say that she wants one yard, or two yards, or three yards, according to her needs. Now how much is a yard? Of course you all know that a yard is three feet. I suppose you all know that a yard is the same length in every city in the United States. We go into the store and ask for a yard of cloth in any city in the country, with absolute confidence that we will get for each yard, three feet in length. But how do we know we will get three feet in length for each yard? How do we know what we will get when we ask for a pound of coffee, or for a ton of coal, or for a quart of milk? These weights and measures are nearly all fixed by law. When you come to read the Constitution of the United States, you will find that there is conferred upon the United States government the power to “_fix the standard of Weights and Measures_”.(28) The Constitution is the fundamental law of the land. This confers upon the United States government the right to fix all standards of measurements and all weights and measures of every kind. The United States government has this power. It is not required to exercise the power, but it has the power. The United States government has a National Bureau of Standards,(29) which supervises weights and measurements, which coöperates with the States, and maintains uniformity, so that in every State, with reference to most things bought and sold, the law fixes definitely the quantity or dimensions. Without such laws you can see what a mass of confusion the people would be in at all times. Severe penalties are imposed by law upon those who give short measure, or short weight,(30) in order to protect buyers against those who might defraud them. So you see how necessary law is to the simple transactions of life, and how we are constantly relying upon the law in our daily transactions, to protect us against wrongdoers. Then again, how do you know how much the silver dollar which you are saving for Christmas is really worth? How do you know that one dollar is as valuable as another dollar? How do you know that the paper dollar which is in circulation is as valuable as the silver dollar? Well, here again when you read the Constitution of the United States, you will find that the people, when they adopted the Constitution, gave to the Congress of the United States the power: “_To coin Money, regulate the Value thereof, and of foreign Coin_”.(31) Congress, with this power, has enacted numerous laws with reference to the coinage of silver and gold money, the printing of paper money, and fixing the value of such money. How helpless the people would be without such laws.
