From the preceding journal of operations performed under the contract before mentioned, it is shown that notwithstanding the unfavorable weather that has occurred, causing frequent interruptions of the work, during the two months of July and August there have been excavated and deposited, about 500 yards distant from the channel, 23,420 cubic yards of earth. The material removed consists of fine or coarse sand, occasionally mingled with clay or mud. A cut from 40 to 45 feet in width, and about 14 feet in depth, has been excavated entirely through from the river channel to the deep water of the lake. It is proposed to expend the remainder of the appropriation in widening this cut.

The United States sub-agent at the flats informs me that since the channel has been opened a strong current passes through it. The velocity has not yet been measured, but it is probably twice as great
