An additional thirty miles of the first mentioned road have been graded and will probably be finished during the ensuing summer. This, when completed, will extend the line to Marshalltown. "A negotiation has been opened between this and the two last named Companies for leasing their lines by this Company, and thus placing the whole under one management. This negotiation has been thus far without result. It is deemed important that some arrangement should be made, if practicable, for permanently uniting the interests of these Companies and securing the extension of the joint line to the Missouri River, in time to influence the location of the system of Railroads, which will grow up beyond that river."
