bar thus formed. As a remedy for this evil, the dredging of a channel is recommended by the officer in charge, and an appropriation of $80,000 is asked for the purpose. It is also proposed to continue the system of stopping, with sods, whatever leaks appear in the sheet-piling, and of refilling the holes in the embankment behind them with earth. For this purpose, and for the services of the custodian of the canal, the additional sum of $5,000 is recommended for the next fiscal year. Amount available December 11, 1871, the date of the transfer of the work to Major Poe.... Appropriation of March 3, 1871 Appropriation of June 10, 1872. Expended to July 1, 1872 Amount available July 1, 1872 Amount required for the fiscal year 1873-74 Since the preparation of this portion of the annual report, a communication has been received from the officer in charge, under date of October 3, urging that the full amount of his estimate for this work be appropriated, and stating that since making his annual report the depth in the canal has been practically reduced to 11 feet 6 inches, principally by the action of the wheels of heavily-laden propellers. This difficulty can be obviated by increasing the depth of the canal, as recommended in the report from this office of January 9, 1872, on Senate bill No. 345, "for deepening Saint Clair Flats Canal to 16 feet." The amount estimated for this purpose was $40,000, which sum, in addition to that of $85,000, is recommended to be appropriated, making the total required $125,000. The estimate for this work submitted through the Treasury Department was $85,000. It should be increased as here indicated. (See Appendix C 9.) EXAMINATIONS AND SURVEYS FOR IMPROVEMENT.
