from the upper end of Deadmans Island to the lower end of the wharves, and for full width between wharves, over a distance of 1,180 feet. A total of 764,250 cubic yards of material consisting of rotten sandstone, broken shell, yellow and blue clay, sand, cobbles, and quicksand was dredged, pumped 542 to 2,264 feet and wasted as follows: 70,728 cubic yards west of the west jetty, 256,455 cubic yards on the United States reservation east of the east jetty, and 437,067 cubic yards on the concession of the Pacific Wharf & Storage Co. The dredging was done at a total cost of $69,673.20, or $0.091 per cubic yard, including superintendence and office expenses. The repair work done to the dredge during the year is estimated to more than equal its deterioration for that time, so that the dredge is at present in better condition than a year ago.

Considering the actual pumping time for the entire year, the solids amounted to about 4.1 per cent of the total flow through the discharge pipe.

Miscellaneous work. No dredging was done during October and November. During this time every part of the dredge machinery and the floating plant was thoroughly overhauled by the engine room and deck crews, the only extra labor employed being one boiler maker and two ship carpenters. The ladder of the dredge was lengthened to permit of dredging to increased depth and the dredge frame reinforced with additional hog chains at a total cost of $2,859.37. Dredging laterals to 20-foot depth.-Under appropriation of $200,000 made by river and harbor act of June 25, 1910, a contract was entered into October 15, 1910, with the Tacoma Dredging Co., of Tacoma, Wash., for dredging channels 20 feet deep and 200 feet wide from the turning basin into the east and west basins, respectively. Dredging began in the east basin January 10, 1911, and up to the close of the fiscal year 616,735 cubic yards had been dredged with the 20-inch suction dredge Oakland at a cost of $0.089725 per yard. This material was deposited behind a bulkhead on the northerly side of the channel and on the land of the San Pedro, Los Angeles & Salt Lake Railroad Co. on the southerly side of the east basin. Dredging has been done over a distance of 6,100 feet of channel to the full project width but not to full project depth.

In March, 1911, unusual floods in the San Gabriel and Los Angeles Rivers caused the former to break into the latter, with the result that the Los Angeles River, which normally flows into Long Beach Harbor, deposited a considerable amount of silt in the harbors of Los Angeles and Long Beach. A shoaling, diminishing from about 3 feet at the northeast corner of the east basin to nothing at about Fifth Street, San Pedro, resulted. The material deposited over the area involved will be removed under the existing project which provides for dredging to increased depth. No estimate of the cost of preventing a recurrence of such deposit is given, since an adequate project for flood control of these rivers would involve an extensive survey, for which no funds are considered available at present.

Estimate of additional funds required.
