In 1857 he removed once more, to Washington, still following his business. This now began to consist largely of heavy patent cases, a peculiar and difficult but very gainful department of legal practice. It is observable that the class of cases in which Mr. Stanton has been prominent, are those in which the executive mental faculties have most to do with the subject-matter--patent cases, land cases, vigorous controversies between great corporations about travelled routes or conflicting rights. Such cases arise among executive men, and Mr. Stanton's immense endowment of executive energy qualified him to succeed easily in dealing with them. Mr. Stanton was naturally a Democrat; the vigorous traits of his character harmonizing spontaneously with the rough, aggressive energy of the Jacksonians. Probably his politics may have had some influence in causing Attorney-General Black to employ him, in 1858, to go to California and argue for the United States some very important land claim cases there. At any rate, if he had not been a Democrat, and a thoroughgoing one, he would not have been selected by Mr. Buchanan in December, 1860, to succeed Mr. Black as Attorney-General, when on Mr. Cass' resignation Mr. Black became Secretary of State. The gang of treasonable schemers who were in those days using their high positions to bind the country hand and foot, as securely as they could, in preparation for secession, undoubtedly had reckoned that in the new Attorney-General, if they did not find an ally, they would not encounter an obstacle. But his patriotism was of a very different kind from that of too many of his party. When the question before him, instead of being one of high or low tariff, or of one or another sort of currency, became a question whether he should go with his party in permitting his country to be ruined, or should join with all true patriots irrespective of party considerations, to preserve his country, he did not hesitate at all. He neither made allowances for the disreputable fright of old Mr. Buchanan, nor the far more disreputable schemes of the traitors who were bullying the feeble and helpless Old Public Functionary; but stood firmly amongst them all, a fearless and determined defender of the rights of the national government. Mr. Stanton once gave a curious and striking sketch of the manners of Mr. Buchanan's cabinet in those days. While speaking of the results of Anderson's move to Sumter, he remarked:
