The most alarming movement, however, proceeds from the assembling on the 9th June of the so-called Topeka legislature, with a view to the enactment of an entire code of laws. Of course it will be my endeavor to prevent such a result, as it would lead to inevitable and disastrous collision, and, in fact, renew the civil war in Kansas. This was with difficulty prevented by the efforts of Governor Walker; but soon thereafter, on the 14th of July, we find him requesting General Harney to furnish him a regiment of dragoons to proceed to the city of Lawrence; and this for the reason that he had received authentic intelligence, verified by his own actual observation, that a dangerous rebellion had occurred, "involving an open defiance of the laws and the establishment of an insurgent government in that city." In the governor's dispatch of July 15 he informs the Secretary of State that-- This movement at Lawrence was the beginning of a plan, originating in that city, to organize insurrection throughout the Territory, and especially in all towns, cities, or counties where the Republican party have a majority. Lawrence is the hotbed of all the abolition movements in this Territory. It is the town established by the abolition societies of the East, and whilst there are respectable people there, it is filled by a considerable number of mercenaries who are paid by abolition societies to perpetuate and diffuse agitation throughout Kansas and prevent a peaceful settlement of this question. Having failed in inducing their own so-called Topeka State legislature to organize this insurrection, Lawrence has commenced it herself, and if not arrested the rebellion will extend throughout the Territory. And again: In order to send this communication immediately by mail, I must close by assuring you that the spirit of rebellion pervades the great mass of the Republican party of this Territory, instigated, as I entertain no doubt they are, by Eastern societies, having in view results most disastrous to the government and to the Union; and that the continued presence of General Harney here is indispensable, as originally stipulated by me, with a large body of dragoons and several batteries. On the 20th July, 1857, General Lane, under the authority of the Topeka convention, undertook, as Governor Walker informs us-- to organize the whole so-called Free-State party into volunteers and to take the names of all who refuse enrollment. The professed object is to protect the polls, at the election in August, of the new insurgent Topeka State legislature. * * * * *
