Map Of The Territory Of The United States From The Mississippi To The Pacific Ocean Ordered by the Hon. Jeff'n Davis, Secretary Of War To accompany the Reports of the Explorations For A Railroad Route ... Compiled from authorized explorations and other reliable data by Lieut. G.K. Warren, Topl. Engrs. In the Office of Pacific R.R. Surveys, War Dep. under the direction of Bvt. Maj. W.H. Emory, Topl Engrs. in 1854 and of Capt. A.A. Humphreys, Topl. Engrs. 1854-5-6-7. Engr. by Selmar Siebert.

The general map published with the Pacific Railroad Survey Reports. This map had earlier issues and later issues. A preliminary listed of those would be: 1855 (our #2289); 1857 (WH and AH's copies)- blank areas in eastern Oregon, fewer authorities; 1857 published with the reports; 1858 early (see Schubert);1858 late (our #2750); 1867 (our #2594). We suspect there are other states and issues, particularly in the period of 1859 to 1866. This is one of the most important maps of the West in the 1850's and 1860's and a study of its different states shows the rapid growth of topographical information from government exploration and mapping. Without color.
This Quarto issue of the report is the House issue, except for volume XI which is the Senate issue. W. Heckrotte has an unusual copy of the Warren U.S. map found in this report. It is dissected on linen and is an earlier version of the map published with the Quarto report. It has 40 authorities vs. 42 in the quarto issue map, shorter note to left of authorities, lots of plate differences, especially: nothing in Owyhee area, differences in N.M., Calif., etc. Looks like someone asked for the map before it was finished -see the Lack of ocean lines in the top half south of Gray's Harbor. In 13 volumes. Bound in full leather with "Explorations and Surveys for a Railroad to the Pacific Ocean" and the volume number on the spine in gold.
