A description of the early conditions of the harbor at the mouth of Huron River and of the projects for its improvement is given on pages 2653 and 2654, Report of Chief of Engineers, 1898. The present project is authorized by the river and harbor act of March 3, 1905, and is given in full in the Report of Chief of Engineers, 1894, pages 3209 to 3218, inclusive. In the spring of 1904 an allotment of $40,000 was made from the river and harbor appropriation of that year for the purpose of maintaining this harbor. About 500 feet at the inner end of the west jetty was in such a ruinous condition that it was likely to be destroyed by any storm, thus involving the destruction of the channel. The funds have been expended during the year in the construction of about 490 linear feet of timber-crib jetty with a timber superstructure. The cribs were built and sunk in place before the close of the working season of 1904, and although the superstructure was not completed over them they were high enough to thoroughly protect the channel. The superstructure is now being built by hired labor. The 490 feet of structure was not quite sufficient to run to the shore. It left a gap of about 70 feet through which the sea worked, causing the shore line to recede. This was temporarily checked by a mattress of timber, brush, and stone. The gap is now being closed by a coffer of two rows of 12 by 12 tongued and grooved sheet piling driven in prolongation of the crib walls and tied together and braced by 4-pile trestle bents placed 8 feet apart to conform to the ordinary cross walls of a erib. This coffer will be filled with stone and a superstructure built upon it, so that it will resemble the rest of the work. It is of such a character that it can carry a concrete superstructure whenever this style of top is placed upon the other portion of the jetty. The river and harbor act of March 3, 1905, appropriated $68.500 for this harbor, and authorized contracts to the amount of $200,000 more. The funds available will be applied to the extension of the west jetty 240 feet and to building the two pierheads. The cribwork will be built and sunk by hired labor. Arrangements are now being made to purchase the material. Proposals will be invited for the execution of the rest of the work by contract when the proper time arrives.

BLUNT, ASSISTANT ENGINEER. 260 Begun. Launched. Completed. 259,013 TOLEDO, OHIO, July 1, 1905. COLONEL: I have the honor to submit the following report upon Huron Harbor, Ohio, for the fiscal year ending June 30, 1905: All depths mentioned are given at mean level of Lake Erie, 1860-1875, surface being now about 0.3 foot above that level. At the beginning of the fiscal year there had been ordered about 770,000 feet of timber and 110 tons of iron to be used in the construction of about 500 feet of west pier, to connect as closely as possible with the shore, under an emergency appropriation of $40,000, the work to be done by day labor. The delivery of material began July 12, and was completed September 27. As soon as sufficient material was on hand the construction of cribs was begun in lengths of 122 feet 8 inches, as heretofore, each having 15 pockets, 8 feet on centers. Numerous delays were met, owing to nondelivery of material, strikes at stone quarry, etc., but on the whole the construction and sinking of the four cribs was done with considerable expedition, as shown in the following table: 502, 848 701, 385 198, 537 187,801 188,267 376,068 616, 775 240, 707 Sunk. July 25 Sept. 10 Oct. 8 Nov. 2 8 Oct. 22 Nov. 4 29 Nov. 10 Nov. 12 24 Nov. 30 Dec. 5 The removal of old pier and preparation of trench was done by U. S. dredge During and after the sinking of cribs there was considerable heavy weather from the westward, which threw them somewhat out of alignment, especially at the outer end of crib No. 6, where an angle in the line was made. At this point No. 6 was thrown about 2 feet into the river, necessitating a special construction for its protection. Work on superstructure was postponed until spring, and up to June 30 the walls have been built to grade, but decking is not yet on. These cribs carried the pier close to the old pile protection along the shore, but in dredging the bed the pile protection was destroyed, so that a gap existed about 60 feet wide. During the winter the seas washed through and attacked the shore, so that it became necessary to protect it by a rough mattress loaded with timber, logs, stone, etc. The cutting was thus checked, but the gap to be closed had become 80 feet wide. By your direction this is being closed by a pile structure. Round piles are first driven in four-pile bents 8 feet apart along the axis, all within the exterior lines of the pier. These serve first as a trestle for support of driver and then as a base for cross walls. Along the exterior lines of pier will be driven sheet piling of 12 by 12. inch timber with 3 by 4 inch pieces planted on to form tongue and groove. The cross walls will be built up with corner posts and braces, and the interior filled with stone. On June 30 there had been driven 28 round piles, under informal agreement with John J. Stang, for driving, the material having been purchased in the open market. Under the provision of the river and harbor act of March 3, 1905, specifications were issued June 27 for furnishing at Huron Harbor about 656,000 feet of timber and 103 tons of iron for use in building the west pier extension and the two pierheads by day labor. Soundings taken by Inspector Simpson in the spring of 1905 indicated a general depth of 20 feet and upward outside the piers and a good channel exceeding 21 feet between the piers throughout. Very respectfully, Lieut. Col. DAN C. KINGMAN, Corps of Engineers. WM. T. BLUNT, United States Assistant Engineer. PP 5. IMPROVEMENT OF VERMILION HARBOR, OHIO. For a description and history of this improvement see page 2696, Report of Chief of Engineers, 1898. No funds were available for the improvement of this harbor at the beginning of the fiscal year 1905. An examination and survey had been made under authority of the river and harbor act of June 13, 1902, and a plan of improvement based upon a survey had been submitted. This plan was adopted by Congress in the act of March 3, 1905. The only object proposed under this plan is to repair the existing jetties in a durable and permanent manner. The superstructures will be removed to the level of the water surface, side walls will be reenforced by heavy riprap having slopes of 1 on 14. These slopes will be continued above the surface of the water, so as to give the jetties a height of 5 feet. The stone will be of sufficient size so as not to be disturbed by waves, ice, or currents; and above water the large stones will be regularly laid in the form of a pavement. The estimated cost of this work is $42,350. The act of Congress last above referred to appropriated $15,000 for carrying on the work. Plans and specifications have been prepared, proposals invited, and a contract let to provide for the expenditure of |
