Description
1 map : col. , 34 x 29 cm . "Population 174,768 ". "Area , square Miles 94,560 ". George F . Cram , a Union soldier who fought in Sherman's Army during the Civil War , returned home in 1867 to Evanston , Illinois to begin a map and atlas company with his uncle , Rufus Blanchard . By 1875 , Cram owned his own publishing company in Chicago and soon rose to success by using a wax engraving process (similar to that perfected by the Rand McNally Company , his greatest competitor) . Invented in 1834 by Richard Cary Morse and Henry A. Munson , the wax engraving process--also known as "cerography--was not patented until 1848 . This allowed for many engravers to perfect their own version of the method . Among them was the Rand McNally Co. , which began printing maps in 1872 , using a combination of Morse's wax process and electrotyping . Invented in Russia , 1839 by a German named Jacobi , electrotyping took wax engraving one step further by coating the surface with a substance such as graphite (electrically conductive) and then submerging it all into an electrolytic bath and copper coating . When ready , the wax was then removed and the copper plate became the template for printing . While of less quality than lithography , it also cost less . By the 1890s most American publishing houses used this wax process . Cram retired in 1921 , selling out to the National Map Company . In 1928 , the company returned to the Cram name and it has continued in business to this day .

Digitization
Original maps were scanned in color at 600 dpi on a Microtek 9600XL scanner and saved as TIFF files. The TIFF files were converted into the MrSID format at a compression ratio of 12 to 1 using LizardTech's Geospatial Encoder 1.4 software. These MrSid files were then uploaded into the CONTENTdm database at the Washington State University Libraries.
