Very early issue of Warren's Pacific Railroad general map of the U.S. When the Pacific Railway Survey reports were published in 1855, the large Warren map of the U.S. was not completed and a smaller map was issued with a note by Warren that the larger map would soon be ready for publication. This issue of the map is dated 1855 only, unlike the final issue which was dated 1854-5-6-7 (see our #0693). Also, the list of authorities here is shorter than the later issue and has no dates later than 1855. Most importantly, this issue has major areas blank that are filled in the final issue. Various routes are drawn in ms on the map, in red and blue lines, all proceeding from points in the Midwest to the west coast, as well as some north - south routes. Also, a red line is drawn from east to west next to the 38th parallel. We think these are the trails used by travelers, perhaps a few years later, but we can't be sure. There is another early issue of this map that is between this 1855 issue and the version published with the final reports - it is dated 1857, has fewer "blank" areas that this and has more and later dated authorities (see WH copy).
