It was his fortune at the time the legal tender clause was inserted in the bill to authorize the issue of United States notes and received the sanction of congress, to be charged with the anxious and responsible duty of providing funds for the prosecution of the war. In no report made by him to congress was the expedient of making the notes of the United States a legal tender suggested. He urged the issue of notes payable on demand in coin or received as coin in payment of duties. When the state banks had suspended specie payments, he recommended the issue of United States notes receivable for all loans to the United States and all government dues except duties on imports. In his report of December, 1862, he said that "United States notes receivable for bonds bearing a secure specie interest are next best to notes convertible into coin," and after stating the financial measures which in his judgment were advisable, he added: "The secretary recommends, therefore, no mere paper money scheme, but on the contrary a series of measures looking to a safe and gradual return to gold and silver as the only permanent basis, standard, and measure of value recognized by the constitution." At the session of congress before this report was made, the bill containing the legal tender clause had become a law. He was extremely and avowedly averse to this clause, but was very solicitous for the passage of the bill to authorize the issue of United States notes then pending. He thought it indispensably necessary that the authority to issue these notes should be granted by congress. The passage of the bill was delayed, if not jeoparded, by the difference of opinion which prevailed on the question of making them a legal tender. It was under these circumstances that he expressed the opinion, when called upon by the committee of ways and means, that it was necessary; and he was not sorry to find it sustained by the decisions of respected courts, not unanimous indeed, nor without contrary decisions of state courts equally respectable. Examination and reflection under more propitious circumstances have satisfied him that this opinion was erroneous, and he does not hesitate to declare it. He would do so, just as unhesitatingly, if his favor to the legal tender clause had been at that time decided, and his opinion as to the constitutionality of the measure clear.
