Reports of explorations and surveys, to ascertain the most practicable and economical route for a railroad from the Mississippi River to the Pacific Ocean
A United States War Department survey report published in Washington in 1855, issued to find the most practicable railroad route from the Mississippi to the Pacific, with natural history plates appended for that purpose. The fish plates, drawn in plain outline with stippled shading, show whole fish viewed from above or below alongside small scale or otolith details, a useful reference for scientific line drawing and specimen-plate layout with labelled figures.
