The Union men of St. Louis not only saw the danger arising from the continuance of the Convention in Jefferson City, but they determined if possible to avert it. Having in secret seriously considered the whole matter, they cautiously and wisely laid their plan to bring the Convention to their own city. Since many men in the State were deeply prejudiced against St. Louis, regarding it as the stronghold of Free-soilism, it was necessary carefully to conceal the movement that was being made. If any delegate from St. Louis had openly moved that the Convention should adjourn to our city, the motion would undoubtedly have been promptly and decisively voted down. But the delegates from St. Louis, instead of making an open move, quietly and unobserved found some delegates from the country to whom they deemed it safe to make their suggestions, and without any knowledge of it on the part of the Convention these men were won to their ideas. When, therefore, the Convention, on the second day of its session, was perfecting its organization, Mr. Hall of Randolph County,—a strong pro-slavery district near the centre of the State,—moved that when the Convention adjourned, it should adjourn to meet “in the Mercantile Library Hall of St. Louis, on Monday morning next, at 10 o’clock.” The motion met with strong opposition, but after some discussion it became evident that there was probably a majority in its favor. Still, the Convention, wishing to act prudently in a matter of such vital importance, inquired if it were certainly known that they could occupy the hall mentioned in the motion of the gentleman from Randolph County? This brought to his feet Judge Samuel M. Breckinridge, a delegate from St. Louis, who said that at the request of some members from the country, he had already telegraphed to St. Louis, and had received an answer that the Convention could occupy without expense either of the two halls belonging to the Mercantile Library Association. The undivulged fact was that the Union men of St. Louis, days before, had arranged to offer to the Convention, without cost, either of these halls, if by any means that body could be induced to occupy it. At last, to remove any objection that might arise from pecuniary considerations, the citizens of our city telegraphed that the railroad fare of all the members of the Convention had also been provided for; so, at the close of the second day’s session at Jefferson City, on March 1st, the Convention, by a decided majority, adjourned to meet on the following Monday, March 4th, at 10 A. M. in the Mercantile Library Hall of St. Louis; and by that move the doubt that Missouri would secede from the Union was greatly strengthened.
