Mr. J. G. JACKSON replied to Mr. WILLIAMS. The gentleman had asked emphatically why Congress should convene here in May. Occurrences of every day, said Mr. J., are presenting themselves in such a way as to render it highly important and necessary that some other ground should be taken. Are we to adhere to the embargo forever, sir? I have said, and again say, that a total abandonment of the ocean would be submission. I think, by passing this bill, we give the nation a pledge that it shall be the _ne plus ultra_, which shall give to foreign nations time to revise their conduct towards us, and will give them time to consider whether or not they will have war with us. The gentleman wants a special mission. Sir, are we to continue in this state any longer? Shall negotiation be spun out further? No man can doubt the capacity of our Ministers abroad, and their disposition to represent their Government correctly. The doors are shut in the face of our Minister at the Court of St. James, and worse than shut at the Court of St. Cloud--for, from the latter, contemptuous silence is all the answer we have received, if indeed silence can convey an answer. Are we to renew negotiation, then, when every circumstance manifests that it would be useless? Need I refer to what took place the other day--I allude to the publication of a letter by Mr. Canning, in a highly exceptionable manner, through Federal presses, or presses more devoted to the interests of that country than any other? One universal burst of indignation accompanied the publication of that letter in this House. And are we, under such circumstances, to renew negotiation by extra missions? I conceive that the cup of negotiation and conciliation is exhausted to the dregs, and that we should but further degrade ourselves by sending further extra missions. It has been stated to me that a proposition had actually been reduced to writing by a member of this House the other day for sending away foreign Ministers and calling our Ministers home, and I am sorry that the proposition was not offered to the House, for, under present circumstances, it might not have been improper to have adopted it. Mr. SMILIE said, if there were no other reason, the present suspension of commerce, and discontents at home, were sufficient reasons for calling Congress earlier than the first Monday in December. When the new Administration should come into office, it was proper that they should have an opportunity of meeting Congress as early as possible. It was his opinion that, at the next session, a change of measures would take place. What would be the substitute for the present measure he could not say; but, at this time, he must say that he could see no way of avoiding war. With regard to extra missions, he really had no idea of a measure of that kind. If there should be any other means to secure the interest and honor of the nation but war, he hoped in God that it would be adopted, but he did not now see any such prospect.
