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.
