The report of the Post Master General is referred to as exhibiting a highly satisfactory administration of that Department. Abuses have been reformed, increased expedition in the transportation of the mail secured, and its revenue much improved. In a political point of view this Department is chiefly important as affording the means of diffusing knowledge. It is to the body politic what the veins and arteries are to the natural--conveying rapidly and regularly to the remotest parts of the system correct information of the operations of the Government, and bringing back to it the wishes and feelings of the people. Through its agency we have secured to ourselves the full enjoyment of the blessings of a free press. In this general survey of our affairs a subject of high importance presents itself in the present organization of the judiciary. An uniform operation of the Federal Government in the different States is certainly desirable, and existing as they do in the Union on the basis of perfect equality, each State has a right to expect that the benefits conferred on the citizens of others should be extended to hers. The judicial system of the United States exists in all its efficiency in only fifteen members of the Union; to three others the circuit courts, which constitute an important part of that system, have been imperfectly extended, and to the remaining six altogether denied. The effect has been to withhold from the inhabitants of the latter the advantages afforded (by the Supreme Court) to their fellow citizens in other States in the whole extent of the criminal and much of the civil authority of the Federal judiciary. That this state of things ought to be remedied, if it can be done consistently with the public welfare, is not to be doubted. Neither is it to be disguised that the organization of our judicial system is at once a difficult and delicate task. To extend the circuit courts equally throughout the different parts of the Union, and at the same time to avoid such a multiplication of members as would encumber the supreme appellate tribunal, is the object desired. Perhaps it might be accomplished by dividing the circuit judges into two classes, and providing that the Supreme Court should be held by these classes alternately, the Chief Justice always presiding. If an extension of the circuit court system to those States which do not now enjoy its benefits should be determined upon, it would of course be necessary to revise the present arrangement of the circuits; and even if that system should not be enlarged, such a revision is recommended. A provision for taking the census of the people of the United States will, to insure the completion of that work within a convenient time, claim the early attention of Congress.
