Under this, contracts have been made for removing about 60,000 cubic yards from the channel across the inner bar, and for removing the sunken cribs near the east end of the north pier, and extending this pier eastwardly 120 feet. The channel across the inner and outer bars will be widened to 350 feet (the width between the piers at the beaconlights on north pier) and will have a depth of 15 feet at low stage of water. The allotment of $10,000 for the protection of the peninsula will be expended during the year in the purchase and planting of trees, and in the construction of jettees of brush and stone at the threatened points. No appropriation is required for the next fiscal year. Amount probably required annually to keep the piers and breakwater in repair, $1,500. Amount on hand, July 1, 1870.

These were made by Major McFarland, Corps of Engineers, and submitted to Congress February 4, 1871. The improvement he suggests for Port Clinton Harbor requires about 4,500 feet of pier-work, at a cost of $120,000, including the deepening of the entrance to Portage River to 8 feet. To make a harbor at Rocky River, either for commercial purposes or as harbor of refuge, a large amount of dredging would be required, and also the construction of a protecting pier. Major McFarland estimates the cost of a pier at $30,000, and the cost of dredging a channel, 100 feet wide and 12 feet deep, from the outside of the outer bar along both sides of the island in the river, to be from $48,000 to $132,000, according as the material to be excavated may or may not prove to require blasting. (See Appendixes D 16 and 17.) The resurvey of Monroe Harbor, Michigan, and the survey of Maumee River, above Toledo, Ohio, directed to be made by the act of March 3, 1871, are in progress, under the direction of Captain Gillespie.

Dunkirk Harbor, New York.-The west pier was secured and re-enforced during the working season of 1869, and now stands in good and safe condition. The removal of the old outer breakwater was completed in 1871; preparations to carry into effect the plan of the board of engineer officers of November 3, 1870, were made, and the work commenced at the close of the fiscal year, 1870-'71; and by the close of the working season the day-beacon will be established, and 200 feet of breakwater laid, exhaustexisting appropriation.

BRIDGE ACROSS THE NIAGARA RIVER AT BUFFALO, NEW YORK. The act of Congress of June 30, 1870, authorizing the construction and maintenance of this bridge, required that it be subject in its construction to the supervision of the Secretary of War, to whom the plans and specifications should be submitted for approval. To supply all necessary information on the subject a board of engineer officers was convened to examine and report upon the plan and location of the bridge. Their report, and the action taken thereon, will be found in Appendix E 4. HARBORS ON LAKE ONTARIO AND THE RIVER SAINT LAWRENCE. Officers in charge, Major N. Bowen, Corps of Engineers, to November, 1870; Lieutenant B. D. Greene, Corps of Engineers, to January, 1871; and Major John M. Wilson, Corps of Engineers, since that month. 1. Olcott Harbor, mouth of Eighteen-Mile Creek, New York.-During the fiscal year the east pier has been extended 150 feet, making its total length 588 feet, and the west pier 180 feet, making its length 698 feet. Timber and stone were purchased in the winter for the prosecution of the work in the spring. During the present season it is proposed to add 140 feet to the east and 90 feet to the west pier. To complete the project will require, in addition to the above, that each pier be further exended 180 feet, and that 57,000 cubic yards of material be removed by dredging; the whole at a cost of $35,000.

During the winter stone and plank were purchased for this season's work. In May, 1871, contracts were made for the completion of the piers and for dredging the channel. Work was resumed on the piers June 12, 1871, and two cribs were placed in position and sunk by the close of the fiscal year. During the present season it is proposed to add 180 feet to the west pier and 120 feet to the east, and to dredge a channel 150 feet wide to the deep waters of the lake.

Harbor of Oswego, New York.-During the fiscal year the pier running out from the light-house has been completed, 437 feet of superstructure having been built. The old breakwater was fully repaired last season, and one crib constructed for the new outer breakwater. Contracts have been made for the repair of the old pier, which had been badly damaged during the winter, for a breakwater in the angle near the light-house, and for stone and labor on the new outer breakwater. Work is progressing satisfactorily on all of these. During the present season it is proposed to complete the repairs of the old breakwater, to build a short breakwater in the angle near the lighthouse, and to construct about 600 feet of the new breakwater for the outer harbor. The board of engineer officers that had submitted a plan in March, 1870, for increased harbor facilities at this place, was reconvened in May last to take into consideration the proper application of the appropriation for this purpose in the act of March 3, 1871-the question being whether the breakwater should be commenced at the western end, where it connects with the shore, or at the east end opposite the entrance to the harbor. The town of Oswego, however, having requested that the breakwater be commenced at its western end, because affording the additional harbor room so pressingly needed at an earlier day than if commenced at the eastern end, the board recommended that this request be acceded to. This recommendation was approved by you, and the work was commenced accordingly at the western end. Amount on hand July 1, 1870....

Harbor of Ogdensburgh, New-York.-During the year dredging has been carried on in the Oswegatchie River below the bridge, and in the St. Lawrence, in the channel, parallel to the city docks; 2,952 cubic yards of material, hard to dredge, have been removed from the Oswegatchie ; and 8,814 cubic yards of similar material, and 57,437 cubic yards of clay, sand, saw-dust, &c., from the St. Lawrence channel. During the present working season it is proposed to remove a boulder from the channel of the Oswegatchie, and to dredge such a portion of the St. Lawrence channel as the funds on hand will admit.

EXAMINATIONS AND SURVEYS FOR IMPROVEMENT. Mouth of Salmon River, Port Ontario, New York.-A survey of this locality was made by Lieutenant B. D. Greene, Corps of Engineers, in compliance with the act of July 11, 1870. A special report upon a survey of this locality, made in compliance with a resolution of Congress of January 17, 1868, will be found printed in Ex. Doc. H. R. No. 119, Fortieth Congress, second session, and also in my annual report of October 20, 1868. With this report an estimate was submitted of $209,000 as the probable cost of closing the present channel and cutting a new one 200 feet wide and 12 feet deep through the sand-spit at Wind Gap, and for dredging out the middle of Selkirk Pond to 10 feet, to give harbor room. In the report now submitted, the engineer officer in charge omits the item of dredging Selkirk Pond and makes other modifications, which reduce the estimate to $113,000. As it does not appear that the wants of commerce and navigation require the construction of a harbor of any considerable magnitude, this estimate is limited to an improvement which shall enable vessels to pass readily into and out of the river.

Plattsburgh Harbor, New York.-During the year one crib 94 feet long and 25 feet wide has been sunk and filled with stone, and another crib, 150 feet long and 25 feet wide, has been commenced, making an addition to the breakwater of 224 feet in a northeasterly direction. The work is done by contract. An appropriation of $23,000 will be required for the next fiscal year in order to complete the breakwater, |
