To these London articles may be added passages from Miss Martineau’s correspondence with the _Antislavery Standard_, of New York. In a letter under date of July 2, the eminent writer said:-- “I may just say that Senator Chesnut’s commentary on Mr. Sumner’s speech is very amusing here. He cannot know much of the English aristocracy, if he supposes that strangers can get at them by their back doors. Their back doors are well looked to; but in Mr. Sumner’s case there was no question of back door or front. Our aristocracy went out to seek him,--not he them. I need not say that we heartily rejoice in the full truth having been spoken in Congress. The occasion brings back vividly to my memory Mr. Calhoun’s countenance and voice, when he insisted to me, peremptorily putting down all argument, that that day would never come: there would be silence about Slavery in Congress world without end. This was in 1835. It must be also needless for me to say that no unprejudiced man or woman here really supposes that any terms can be kept with Slavery and Slaveholders. The crisis of your revolution may be precipitated by such open defiance in the Federal Legislature; but we see that it was the South which brought on the revolution and uttered the defiance, and that the only course for the Senator from Massachusetts is to take care that the revolution is steered straight by compass while there is such a fearful tampering with the helm. To speak gingerly of Barbarism, when his business was to set before his country the choice between Barbarism and Civilization, was, of course, impossible; and there could be no fidelity short of such a thorough exposure and denunciation as he has offered.” Then, under date of July 16, Miss Martineau wrote again:--
