The following proclaimation has just been issued in an extra Democrat:To the citizens of Missouri: Prior to the proclamation issued by Gov.Jackson,of date 12th of June,it was well known to you that the Govenor and Legislature sympathized with the rebellion movements now in progress in the country,and had adopted every means in their power to effect a seperation of this State from the General Government.For this purpose parties of avowed Secessionists have been organized into military companies,throughout the State with the full knowledge and approval of the Govenor.The establishment of encampments in the State at an unusual period of the year,and authorized for an indefinite period,could have had no other object than the concentration of a large military lforce,to be subject to the provisions of the military law then in contemplation,and subsquently passed-a bill so offensive to all peaceable inhabitants,and so palpably unconstitutional,that it could be accepted by those only who were willing to conform to its extraordinary provisions,for the purpose of effecting their cherished object,the disruption of the Federal Government.That bill provides for an obligation to the State on the part of all persons enrolled under its provisions,irresdective of any obilgations to the United States,when the Constitution requires all States officers to take an oath of ailegiance to the United States...........Part 2 tomarrow
