LEAVENWORTH, KANS. Plate A.-This plate has been drawn from information furnished through the courtesy of Mr. A. J. Tullock, proprietor and engineer of the Missouri Valley Bridge and Iron Works, Leavenworth, Kans. The borings were made between January 16 and February 20, 1893, while the bridge was in course of construction. Mr. Tullock states that in sinking Pier II "the sand was very clean and very fine, excepting where it was found with gravel. The gravel found in the caisson was very small." In sinking the caisson for Pier IV many large logs were encountered; one log was found in sinking caisson II and none in sinking caisson III. JEFFERSON CITY, MO. Plate B.-This plate is a reproduction of drawings of borings taken between February 28 and March 15, 1894, obtained from Mr. J. A. L. Waddell, consulting and bridge engineer, Kansas City, Mo., by the permission of a company formed to bridge the river at this point. The same method of making the borings was adopted as had been used at the Sibley bridge, and is fully explained in the report of the Missouri River Commission for 1890, p. 3379. Borings were made on two crossings about 0.6 mile apart, four on each section, and were carried to bed rock in each instance. The drawing contains all the information at hand in regard to strata passed through. ST. CHARLES, MO. Plate C.—This plate is also a reproduction of a drawing furnished by Mr. Waddell. The borings were made in 1892 and were not completed over the entire section on account of high water. The drawing exhibits the strata passed through in making the two borings. APPENDIX A 6. ANNUAL REPORT OF J. A. SEDDON, ASSISTANT ENGINEER, 1894. SIR: I have the honor to submit the following report on the study of physical data for the fiscal year ending June 30, 1894: The study of flood movement by the method of "extension gauge relations," completed in the Lower Mississippi, has been carried up the Missouri to Kansas City, through all the gauge records to date. While in general the movement is similar to that of the Lower Mississippi, yet there are irregularities in the Missouri which are not fully understood. It is hoped that further light will be thrown on these by the extension of the study to Sioux City, when this will be made the subject of a special report. A preliminary study by gauge relations was made of Missouri River regimen from Kansas City down. This study of regimen is based on the idea that between two gauges all the hydraulic properties of the channel through the whole reach, from low to high water, are summed up and given graphically in the line of gauge relation; for this line gives at each point the fall between gauges for that stage, or the summation of all acting resistances to flow through the reach. A fixed change in the line of gauge relation is thus a change in regimen, and while perhaps infinitely complex in its pool and bar and section phenomena, in this summation of fall it is closely determinate and its changes readily seen in the gauge relations. The study of regimen by gauge relations cousists in the search for some order or method in these changes. In this preliminary study of the Missouri River so far no method has been seen, and it may be that it is there hopelessly complicated by independent local changes. The subject is being pursued in Lower Mississipi data, where some order has been already found in regimen and its changes, which has been embodied in several special reports not yet published. Very respectfully, your obedient servant, J. A. SEDDON, APPENDIX A 7. Index of surveys and physical data in annual reports Missouri River Commission from 1885 to 1893, both inclusive. Annual report.
