He (Mr. T.) would embrace the present opportunity of saying a few words respecting his own mission to the United States. It had been much denounced as an impertinent foreign interference; but he thought the charge had neither grace nor honesty when it came from those who were engaged, and, as he believed, most conscientiously and praiseworthily, in seeking, by their missionaries and agents, to overturn the institutions, social, political, and religious, of every other quarter of the globe. Mr. Breckinridge had said that it would be as just on his part to inveigh against England on account of Roman Catholicism in the west of Ireland, or Idolatry in India, as it was on his (Mr. T's.) to condemn America for the slavery existing in that country. The cases were not quite parallel. Before they could be compared, Mr. B. must prove that the population of Ireland were _constrained_ to worship the Virgin Mary--that in India, men were _forced_ by British Law to worship idols. No British subject was compelled by any law of this country, or any other country to which British sway extended, to be either a _Papist_ or an _Idolator_. But in America, men were converted into _beasts_, "according to law," and their souls and bodies crushed and degraded by a system most vigorously enforced by the strong arm of the _State_. His opponent had said, however, that slavery was not a national sin. He (Mr. T.) had to thank a friend for suggesting an illustration of the knotty problem. Suppose a number of _Agriculturists_ and _Merchants_ and _Highway Robbers_ were to meet together to form a Union, and the Highway Robbers were to say--come, let us unite for the purpose of common security, and common prosperity: we will defend each other, and trade with each other, but we will not "interfere" in each other's _internal_ affairs. You, gentlemen, Agriculturists and Merchants, shall promise that you will take no notice of my felonious and cut-throat proceedings, and I, on my part, will pledge my honor not to intermeddle in the affairs of your farms or counting-houses: and suppose they were to shake hands, complete the bargain, and ratify an indissoluble union of Agriculturists, Merchants, and Highway Robbers! would the world hold the farmer or the merchant guiltless? Mr. B. had said much of the purity and emancipation principles of Massachusetts, and New-Hampshire and Maine. How came it to pass, then, that they were in terms of such close and cordial fellowship with South Carolina, and Georgia, and Louisiana, and so ready to mob, stone, and outlaw those who deemed it their duty to cry aloud on behalf of the oppressed? To return to his own mission. He would never condescend to apologize for speaking the truth. He had a commission direct from the skies, to rebuke sin and compassionate suffering wherever on the face of the earth they existed. This world belonged to God; and all men were His subjects and his (Mr. Thompson's) brethren. Men might be
