Abstract:Most of the elevations in the following list were collected during the years 1889 and 1890, as the basis of a model of the State.

The data were derived as follows: From the Mississippi River Commission were obtained a line of levels from Cairo to Dunleith, a line of levels from Fulton to Chicago along the line of the Chicago, Milwaukee, and St. Paul R. R., a series of charts of the Illinois shore of the Mississippi, and the low water slope of the Mississippi; from the U. S. Lake Survey, a series of geodetic stations between Chicago and Olney ; from the Illinois and Michigan Canal, low water levels of the Illinois River; from the U. S. Geological Survey, a series of charts covering a belt of country about fourteen miles wide, between Chicago and Peoria; from the U. S. Coast and Geodetic Survey, a line of levels from Olney to St. Louis, one from Centralia to Cairo, and low water levels of the Ohio and Wabash rivers; from the U. S. Engineers, the preliminary' survey of the Hennepin Canal; and from various railway companies, profiles of their lines.
