(USNM cat. no. 317669; photo taken by author.) cemetery ... no trains and no business . . hungry men and women went into abandoned stores and took what they wanted. All of this in the latter half of the last century. From St. Louis the fleeing survey party proceeded to Mound City, Illinois, on the Ohio River, close to its confluence with the Mississippi. There it remained until the yellow fever epidemic subsided. By October 12, 1880, Price was placed in charge of a stream-gaging party with headquarters at Clayton, Iowa, on the Mississippi River. His was one of sev- eral such parties the Commission organized for obtain- ing records of discharge, slope, and sediment movement in the upper Mississippi River. The other parties were located at Prescott, Wisconsin; Winona, Minnesota; Hannibal and St. Louis, Missouri; and Grafton, Illinois. The de\ices then available to Price's party for meas- uring stream velocities were rod floats similar to those shown in figure 3 and an Ellis current meter similar to that shown in figure 4. In his official report of May 10, 1883, to the Mississippi River Commission, Price described the work he and his party had per- formed with these devices as follows: During the entire (1880-1881) season, 222 velocity observations [, discharge measurements] were made, of which 85 were with the meter, and 137 with rod-floats. Besides the regular velocity observations for discharge, there were taken 36 sets of vertical observations .... Until the breaking up of the ice on March 29, 1881, all of the velocity observations were measured with the meter. After the ice stopped running, .\pril 12, 1881, all of the velocity observations were taken with the rod-floats, used in connection with the plant. Price's party reinained at Clayton, making stream- flow measurements
