The senate not only differs from the other house in the principle which it represents, but also in the mode of its election, in the term for which it is chosen, and in the nature of its functions. The house of representatives is named by the people, the senate by the legislators of each state; the former is directly elected; the latter is elected by an elected body; the term for which the representatives are chosen is only two years, that of the senators is six. The functions of the house of representatives are purely legislative, and the only share it takes in the judicial power is in the impeachment of public officers. The senate co-operates in the work of legislation, and tries those political offences which the house of representatives submits to its decision. It also acts as the great executive council of the nation; the treaties which are concluded by the president must be ratified by the senate; and the appointments he may make must be definitively approved by the same body.[133] * * * * * THE EXECUTIVE POWER.[134] Dependence of the President--He is Elective and Responsible.--He is Free to act in his own Sphere under the Inspection, but not under the Direction, of the Senate.--His Salary fixed at his Entry into Office.--Suspensive Veto. The American legislators undertook a difficult task in attempting to create an executive power dependent on the majority of the people and nevertheless sufficiently strong to act without restraint in its own sphere. It was indispensable to the maintenance of the republican form of government that the representatives of the executive power should be subject to the will of the nation. The president is an elective magistrate. His honor, his property, his liberty, and his life, are the securities which the people has for the temperate use of his power. But in the exercise of his authority he cannot be said to be perfectly independent; the senate takes cognizance of his relations with foreign powers, and of the distribution of public appointments, so that he can neither be bribed, nor can he employ the means of corruption. The legislators of the Union acknowledged that the executive power would be incompetent to fulfill its task with dignity and utility, unless it enjoyed a greater degree of stability and of strength than had been granted to it in the separate states.
