EXPLORATION AND SURVEY FOR A RAILROAD ROUTE NEAR THE FORTY-SEVENTH AND FORTY-NINTH 
PARALLELS, 1853-54-55. 
THE reports of this exploration and survey will be found in Volume I,* Senate Ex. Doc. No. 
78, 2d session 33d Congress; and House Ex. Doc. No. 91, 2d session 33d Congress.—Quarto 
edition. 
They are accompanied by a map, in three sheets, drawn on a scale of 1 to 1,200,000, 
exhibiting the entire exploration; and a sheet of profile on a horizontal scale of 1 to 3,000,000, 
the vertical scale being 1 to 60,000, or fifty times greater. 
A brief report of the progress of the survey was published in Senate Ex. Doc. No. 29, 1st 
session 33d Congress, which is accompanied by a map of the route from St. Paul to Fort 
Union, drawn on a scale of 1 to 1,200,00. 
A nearly complete report is contained in House Doc. No. 129, 1st session 33d Congress, 
accompanied by a profile and map, in three sheets, showing the entire route, drawn on a scale 
of 1 to 1,200,000. This map is, however, not so complete as the one in the quarto edition. 
An additional report has also been made by Governor Stevens, which will appear in a subse. ` 
quent volume with numerous landscape illustrations. ۱ 
This expedition, as first organized, consisted of four separate parties. The one under 
Governor Stevens’ personal supervision, operated from St. Paul westward towards the mouth 
of White Earth river; thence on the prairies lying along the Missouri river to the Rocky 
mountains; and then among the passes of that region. Another, under Brevet Captain G. B. 
* Vol. I also contains the report of the Secretary of War and Captain A. A. Humphreys on the comparative advantages 
of the routes examined. These are accompanied by a map of the Territory of the United States, from the Mississippi to the 
Pacific, on a scale of 1 to 3,000,000, and a sheet of profiles of all the routes on a horizontal scale of 1 to 3,000,000, and a 
vertical scale of 1 to 60,000. 
1 Ordered by the Senate at the 2d session 35th Congress.
