Article IV. — List of Altitudes in the State of Illinois. By C. W. Rolfe. PREFACE. Most of the elevations in the following list were col- lected during the years 1889 and 1890, as the basis of a model of the State. The others were gathered during the progress of a barometric survey of the State, made under the auspices of the Illinois Board of World's Fair Commissioners. 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 Missis- sippi; 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 cov- ering a belt of country about fourteen miles wide, be- tween 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 va- rious railway companies, profiles of their lines. In order to test and correct the railroad profiles, the bench-marks of the lines of levels and the geodetic points were connected with the nearest railroad stations, the results being used to correct the profiles of these roads ; the elevations of the various railroad bridges over the Illinois and Mississippi rivers above low water, and hence above sea level, were obtained and the railroad profiles List of Altitudes in ILlinois. 37 checked by tliem ; and the relations of the railroads at intersecting points were ascertained, and the profiles of the roads checked on each other, using those that had been corrected by U. S. data as master systems. Barometric profiles were made, with stationary and moving barometers, of such roads as had no profiles, and after the profiles of the other roads had been brought into agreement, these were added and corrected in the same manner. To the outline thus established, the details of the surface between the roads were added by traverses, with bar- ometer and telescopic hand-level, arranged to intersect railroads as often as possible, and practically to bring the observer within sight of every section of land in his district. Prominent points either of elevation or depi'es- sion were visited, and observations made upon them. Many cross checks and other means of correction were applied to overcome errors due to changes in atmospheric pressure, instrumental irregularities, and observation. In regard to the accuracy of the barometric work, it may be said that a county was made the unit of work in these surveys, and that the results obtained in each county in no way depended upon those arrived at in ad- joining territory; in fact, the observer was generally un- informed as to what had been done in the surrounding counties. When the results of these independent surveys were brought together, it was found that a difference of more than twenty feet in the elevation of points along county lines but rarely occurred, the average difference being less than ten feet. The cost of the survey was twenty-four cents per square mile. The figures at the right of the page indicate, in feet, the elevation above the level of the sea. Where the lo- cality name in the left-hand column is followed by the name of a railroad, the locality is a station on that road. Where it is followed by a personal name in the middle column, it is the name of a small town or other rural locality, and the personal name is that of the observer. 38 Illinois State Laboratory of Natural Histoi'y. By the elevation of railroad stations, the level of the track at the platform is intended. For each town not on the railroad, the location of its post office in the years 1891 and 1892 may be understood, and for sections, the elevation of the highest point in the section is given. Grateful acknowledgment is here rendered to the offi- cials of the U. S. Government, as above indicated, to offi- cers of the railroad lines of the State, to Dr. J. Lindahl, ex-State Geologist, for many courtesies during the prog- ress of the survey, and to Mr. J. G. Mosier, whose intelli- gent assistance aided me greatly in the collection of the material. C. W.
