in the affirmative will appear from several very obvious considerations.
No man can be a competent legislator who does not add to an upright intention and a sound judgment a certain degree of knowledge of the subjects on which he is to legislate. A part of this knowledge may be acquired by means of information which lie within the compass of men in private as well as public stations. Another part can only be attained, or at least thoroughly attained, by actual experience in the station which requires the use of it. The period of service, ought, therefore, in all such cases, to bear some proportion to the extent of practical knowledge requisite to the due performance of the service. The period of legislative service established in most of the states for the more numerous branch is, as we have seen, one year. The question then may be put into this simple form: does the period of two years bear no greater proportion to the knowledge requisite for federal legislation than one year does to the knowledge requisite for state legislation? The very statement of the question, in this form, suggests the answer that ought to be given to it.
