The elevations published in the following list are based on the cor- 
rected elevations of several bench marks of the Mississippi River 
Commission between North McGregor, Iowa, and Victory, Wis. The 
corrections which were applied are 1h< i result of adjustment of precise 
leveling in the United Slates by the Coast and Geodetic Survey, in 1900. 
See Report for 1888-01), Appendix No. 8, page 513. 
The leveling was under the direction of Mr. M. llackett, topog- 
rapher, by Mr. T. Burns, levelman. 
All bench marks set in the course of this work are referred to a 
bench mark at Dubuque, Iowa, and are marked with the letters, 
"DUBQ" in addition to the figures of elevation. The elevations 
assumed for the base bench marks in the field were approximately 1 
foot lower than as corrected by the Coast and Geodetic Survey adjust- 
ment. Therefore, the bench marks of this list are stamped in most 
cases 1 foot low.
