veys were made at Diamond Island 614 and at New Town, 618 miles below Cairo. Four bar-survey parties, on the small steamers Venus, Vulcan, Mercury, and Mars, were engaged on this work. The following crossings were surveyed and buoyed when necessary, in addition to those where dredging was required: The steamer Search was used during the low-water season of 1910 as an inspection boat by the superintendent of dredging in examining the condition of the channel and directing the work of the dredges. The steamer Choctaw was also used for one trip in August. In addition to this supervision of the work by the superintendent on the trips of these boats, supplies and men were carried from Memphis to all the dredges and bar-survey parties in the field, and all shoal crossings were sounded. The soundings obtained on these trips are given in Table No. 4. The river at Cairo was unusually low towards the latter part of May, the Cairo gauge reading 14.4 feet on May 25, 1911. This is the lowest May reading since 1895. On May 24, 1911, the dredge Gamma, in tow of the steamer Choctaw, was sent to Point Pleasant to be in readiness there should shoals develop. The survey boat Venus and party accompanied the dredge, and the outfit arrived at Point Pleasant on May 30. The steamer Leota made an inspection trip of the river from Memphis to upper Point Pleasant, leaving the fleet on May 24. The least depth found on this trip was 10 feet, at Round Lake Crossing 160 miles below Cairo. The dredge B. M. Harrod and survey boat Vulcan have been made ready at the fleet to go to Round Lake should it become necessary to dredge there. Up to the date of this report no dredging has been required since the close of the low-water season of 1910, last December. The following papers and plates accompany this report: Money statements.
