2. Sometimes a State is admitted into the Union before it has as many inhabitants as the law requires to one Congressman, in which case the law is relaxed, and they are permitted at least one Representative. Contiguous counties or towns are set apart in this way and numbered as 1st, 2nd, 3rd, &c., Congressional District. In large cities as many wards, lying together, as include the requisite number, are erected into Districts. In case the number of Congressmen allotted to a State is larger than the number of districts, those in excess are voted for by the State at large. They are arranged as soon as possible after every census, so that this does not often occur. In the Western States the number continually increases and changes must be made after each census. By this means the balance of power gradually follows the emigration from East to West. CONGRESSMEN. 3. We have already remarked, in the chapter on Congress that, though the term Congressman properly applies to the members of both Houses, it is by common usage, confined to members of the lower House, those of the upper House being distinguished as Senators, so that the abbreviation M. C. (Member of Congress) is understood to specify a Representative. 4. These are the only members of any branch of the government who are chosen and elected directly by the people, and we may see herein the propriety of their having the control of all enactments for raising money, this being a point of vital interest to the people. The short term assigned them, (two years,) and their election by Districts, enables the people to interfere very soon if their purse strings are drawn too widely open—a very satisfactory reflection to the economical. Any citizen, whether native or foreign born, may become a Member of Congress, if he can obtain the consent of the voters in his district; but he must have been a citizen during the previous seven years. It is an office of dignity and responsibility, and the welfare of the country depends on the wisdom of the people in their choice. CHAPTER XLVIII. CONGRESSIONAL LIBRARY. 1. In the capitol there is a large library, consisting of two parts; one part called the Congressional library, the other, the law library. The latter is made a part of the former by an act of Congress. Both are subject to the same laws and rules, and both are supported by appropriations made by Congress. This institution, called as a whole, “The Congressional Library,” contains the works supposed to be useful to legislators, but is not confined to their use alone. Its use has been extended to the judges of the Supreme Court; to all the heads of departments; to the Attorney General; to all the members of the diplomatic corps, (foreign ministers); to the secretary of the Senate; to the clerk of the House of Representatives, to the chaplains of Congress, to all ex-Presidents, and to the solicitor of the Treasury.
