St. Louis, Dec. 29.
--The Republican this morning announces the reception of a letter from Chicago, dated on the 13th December, and addressed to Major Bell, Commandant of the U. S. Arsenal here, giving an account of a secret meeting of ten persons, who developed a plan to take possession of the Arsenal at St. Louis, and Jefferson Barracks, and remove all the property therein to Kansas.
They reported that $5,000 worth of arms had been sent to Montgomery, and that $10,000 worth were deposited with the Committee in St. Louis.
They expected the assistance of a large number of Germans residing in the neighborhood, most of whom were workmen in the Arsenal.
One hundred men were to be sent from Chicago, together with many others having great familiarity with the internal arrangements of the Arsenal.
