Mr.Webster devoted himself in the Senate to making every effort to mitigate the evils which he had prophesied, and to prevent their aggravation by further injudicious legislation.

His most important speech was delivered at the special session against the first sub-treasury bill and Mr.Calhoun's amendment.

Mr.Calhoun, who had wept over the defeat of the bank bill in 1815, was now convinced that all banks were mistakes, and wished to prevent the acceptance of the notes of specie paying banks for government dues.

Mr.Webster's speech was the fullest and most elaborate he ever made on the subject of the currency, and the relations of the government to it.

His theme was the duty and right of the general government under the Constitution to regulate and control the currency, and his masterly argument was the best that has ever been made, leaving in fact nothing to be desired.
In the spring of 1839 there was talk of sending Mr.Webster to London as commissioner to settle the boundary disputes, but it came to nothing, and in the following summer he went to England in his private capacity accompanied by his family.
