Message to the Senate
To the Senate of the United States:
In compliance with a resolution of the Senate of the 1st instant, respecting the points of commencement of the Union Pacific Railroad, on the one hundredth degree of west longitude, and of the branch road, from the western boundary of Iowa to the said one hundredth degree of longitude, I transmit the accompanying report from the Secretary of the Interior, containing the information called for.
I deem it proper to add that on the 17th day of November last an Executive order was made upon this subject and delivered to the vice-president of the Union Pacific Railroad Company, which fixed the point on the western boundary of the State of Iowa from which the company should construct their branch road to the one hundredth degree of west longitude, and declared it to be within the limits of the township in Iowa opposite the town of Omaha, in Nebraska. Since then the company has represented to me that upon actual surveys made it has determined upon the precise point of departure of their said branch road from the Missouri River, and located the same as described in the accompanying report of the Secretary of the Interior, which point is within the limits designated in the order of November last; and inasmuch as that order is not of record in any of the Executive Departments, and the company having desired a more definite one, I have made the order of which a copy is herewith, and caused the same to be filed in the Department of the Interior.
