SPIRIT LEVELING IN ILLINOIS, 1914 TO 1917, 

- INCLUSIVE.

R. B. MARSHALL, Chief Geographer.

INTRODUCTION.

Cooperation. Equal allotments of funds for this work were made 

by the United States Geological Survey and the State Geological 

Survey of Illinois.

Previous 'publications. The following results of spirit leveling are 

supplemental to and accord with the elevations contained in Bulletins 

421, 493, and 553, and are in agreement with the 1912 adjustment of 

precise leveling by the Coast and Geodetic Survey.

Corrections. The following corrections to Bulletin 553 should be 

noted:

Page 11: A new bench mark set in 1,906 by F. C. Higley before removing

aluminum tablet at Galatia rolling mills.

Page 55: T. 8 N., R. 5 W., about 0.2 mile south by 0.2 mile east of

center of sec. 14, in southwest concrete wing wall of small iron bridge

over creek; bottom of chiseled square, marked "577.7"................ 577. 9

Page 92: Saline Mines, 1.8 miles southwest of, in southwest corner of

road fork; copper nail in rootof 24-inch black-oak tree, marked "389.6".. 389. 66

Personnel. The field work of 1914,1915, and 1917 was done under 

the supervision of W. H. Herron, geographer, under the general 

direction of R. B. Marshall, chief geographer; that of 1916 was done 

under the supervision of G. S. Smith, topographic engineer, under 

the general direction of W. H. Herron, Acting Chief Geographer. 

Credit is given to the different levelmen in the introduction to each 

list. -The office work of preparation of lists was done mainly by 

S. S. Gannett, geographer, under the general direction of E. M. 

Douglas, geographer.

Classification. No precise leveling was done by the United States 

Geological Survey in this State from 1914'to 1917, inclusive.

For primary lines standard Y levels are used; lines are run in circuits or are closed on precise lines, with an allowable closing error 

in feet represented by 0.05-/D, in which D is the length of the 

circuit in miles, sufficient care being given to the work to maintain 

this standard. For circuit closures careful office adjustments are 

made, the small outstanding errors being distributed over the lines.
6 SPIRIT LEVELING IN ILLINOIS, 1914 TO 1917.

Bench, marks. The standard bench marks are of two forms. 

The first form is a circular bronze or aluminum tablet (0 and E, 

PL I), 3£ inches in diameter and one-quarter inch thick, having a 

3-inch stem, which is cemented into a drill hole in solid rock in the 

^wall of some public building, a bridge abutment, or other substantial 

masonry structure. The second form (F, PI. I), used where masonry 

or rock is not available, consists of a hollow wrought-iron post 3£ 

inches in outer diameter and 4 feet in length, which is set about 3 

feet in the ground. The bottom is spread out to a width of 10 inches 

in order to give a firm bearing on the earth. A bronze or aluminum 

bronze cap is riveted upon the top of the post. A third style of 

bench mark with abbreviated lettering (B and D, PL I) is used for 

unimportant points. This consists of a special copper nail 1£ inches 

in length driven through a copper washer seven-eighths inch in 

diameter. The tablets as well as the caps on the iron posts are 

appropriately lettered, and cooperation by States is indicated by 

the addition of the State name (G, PL I).

The numbers stamped on the bench marks described in the fol- - 

lowing pages represent the elevations to the nearest foot as determined by the levelman. These numbers are stamped with -^- 

inch steel dies on the tablets or post caps, to the left of the word 

"feet." The office adjustment of the notes and the reduction to 

mean sea level datum may so change some of the figures that the 

original markings are 1 or 2 feet in error. It is assumed that engineers 

and others who have occasion to use the bench-mark elevations will 

apply to the Director of the United States Geological Survey, at 

Washington, D. C., for the adjusted values, and will use the marknigs as identification numbers only.

Datum. All elevations determined by the United States Geological Survey and the United States Coast and Geodetic Survey are 

referred to mean sea level, which is the level that the sea would assume if the influence of winds and tides was eliminated. This level is 

not the elevation determined from the mean of the highest and the 

|pwest tides, nor is it the half sum of the mean of all the high tides 

and the mean of all the low tides, which is called the half-tide level. 

Mean sea level is the average height of ike water, all stages of the tide 

being considered. It is determined from observations made by 

means of tidal gages placed at stations where local conditions, such 

as long, narrow bays, rivers, and like features, will not affect the 

height of the water. To obtain even approximately correct results 

these observations must extend over at least one lunar month, and 

if accuracy is desired they must extend over several years. At 

ocean stations the half-tide level and the mean sea level usually 

differ but little. It is assumed that there is no difference between 

the mean sea levels determined from observations in the Atlantic 

Ocean, the Gulf of Mexico, and the Pacific Ocean.
