Island was carried out as contemplated, the appropriation of $20,000 in 1873 having been expended for this purpose. The appropriation of this year, $10,000, will be expended in continu ing this work and in repairing the revetment to the cuts through Grassy Island. The sum of $45,000 is required to complete this channel, of which $25,000 may be expended to advantage during the year ending June 30, 1876.

Harbor of refuge at the entrance of the Sturgeon Bay Canal, Wiscon sin. This work was commenced about the beginning of the fiscal year, an appropriation of $40,000 having been made for it in 1873. During the year two pile-piers were constructed, each 762 feet in length. The filling of the piers was not entirely completed. The appropriation of 1874, $10,000, will be expended in completing this filling and in extending each pier 32 feet, increasing the width of the pier from 14 to 18 feet. The estimate submitted by the officer in charge for the further extension of these piers is $60,000. Balance in Treasury of United States July 1, 1873.

Ahnapee Harbor, Wisconsin.-During the season of 1873, the balance of the appropriation for this harbor, made in 1872, since which time there has been no appropriation, was expended in extending the south pier 175 feet, making its total length 620 feet. The north pier is 352 feet in length. The failure of the appropriation in 1873 left the work incomplete. To make this harbor available for any purpose requires a channel to be dredged between the piers into the river. The officer in charge submits an estimate, for continuing the improvement, of $50,000.

Two Rivers Harbor, Wisconsin.-During the past year the superstructure has been built over 1,031 feet of pile-foundation, and the piers filled with brush and stone, making the north pier 900 feet in length, and the south pier 965 feet. The dredge was employed in excavating a channel for vessels of light draught. During the present season the dredge will be employed in continuing the excavation. The piers will be refilled where the filling has settled, and the north side of the channel into the river revetted. The appropriation of this year being but $15,000, and it being proposed to expend a portion of this sum in using the dredge at Ahnapee Harbor, (the cost of the dredge having been paid for equally out of the appropriations for these two harbors,) it will not be practicable to extend the piers this season, though such extension is necessary to the maintenance of the channel. An estimate is submitted by the officer in charge, for the extension of the piers and dredging, of $50,000. Balance in Treasury of United States July 1, 1873.

The superstructure over the two cribs sunk in 1873 will also be built. The repairs of the old superstructure must be continued, and an estimate of $12,000 is submitted for the purpose.

Milwaukee Harbor, Wisconsin.-During the year the sum of $10,000 was applied to widening and deepening the channel between the piers, by dredging. The appropriation of this year, $10,000, will be applied to the same purpose. This harbor may be regarded as completed at present, so far as the extension of the piers is concerned. Periodical dredging will be required to maintain the channel, amounting to an average of $5,000 per annum. It has become necessary, however, to replace the old superstructure built in 1856 and 1857, and it is recommended that this be done with stone masonry, as the cribs appear to have obtained a permanent settlement. The total estimated cost of replacing 2,240 feet of superstructure is about $300,000, and an estimate for $100,000 is submitted by the officer in charge for the next fiscal year.

Racine Harbor, Wisconsin.-During the year the north pier has been extended by sinking two cribs, 50 feet long by 30 feet wide, making an extension of 100 feet, and in dredging 16,773 cubic yards from the channel between the piers. It is proposed to expend the $10,000 appropriation this year in placing one more crib in extension of this pier, and to build the superstructure over the two cribs placed last year. There will be required to complete this harbor for the present the completion of superstructure over the crib to be placed this season and dredging about 25,000 yards in the channel, for which an estimate is submitted.

Kenosha Harbor, Wisconsin.-During the year the balance of the appropriation of 1872 was expended in building the superstructure over the crib sunk in extension of north pier in 1872. There being no ap propriation in 1873 no other work was accomplished. The sum of $10,000, appropriated in 1874, will be applied to sinking one crib 50 feet long and 30 feet wide, in extension of the north pier, and in repairs, as far as possible, of damage caused to old work by the storms of last winter. There is necessary to the further improvement of this harbor an additional extension of 50 feet to the north pier, superstructure over crib to be sunk this season, repairs to old work, and dredging in the channel, for all of which an estimate is submitted.

Chicago Harbor, Illinois.-The work during the year consisted in extending the breakwater southward 1,150 feet, with the exception of the superstructure, and in repairing slight damages caused by collisions and storms. The work contemplated during the coming fiscal year is an extension of the breakwater 150 feet farther south and the completion of the superstructure over the entire work. This will nearly, if not quite, complete the breakwater. It is proposed to defer the construction of the southern breakwater until it is determined whether wharves are to be built on the west side of the new harbor. The work next proposed on the improvement of this harbor is the extension of the north pier 400 feet, for which an estimate is submitted. Balance in Treasury of United States July 1, 1873..

Calumet Harbor, Illinois.-The work during the fiscal year at this harbor consisted in extending the north and south piers each 200 feet, with the exception of the superstructure, and in building the superstructure over the cribs sunk in 1872. 37,465 cubic yards of sand were also removed from the channel between the piers. At the close of operations in 1873 there was a dredged channel between the piers nearly 100 feet wide and 11 feet deep, in the shoalest place. The appropriation of 1874, $25,000, will be applied in further extension of the piers and in dredging.

There has been no appropriation made since 1872, and the amount available is too small to produce any benefit to commerce. As mentioned in former reports, no estimate is submitted for this har bor, as it would be of no benefit to general commerce, and the local requirements are insignificant.

Improvement of the Fox and Wisconsin Rivers.-The improvement of these rivers is being carried on in accordance with the plans heretofore reported, and the results are given in detail in the accompanying reports. The work on the Fox River has been confined to the Lower Fox. It has consisted of repairs to the old locks and dams, more or less extensive according to their condition, and in deepening the levels so as to obtain the maximum draught of water. The old lower combined lock at Little Chute, which was incapable of repairs, was torn out, and is in process of replacement by a permanent lock of stone masonry. This work is approaching completion. The old dam at Appleton was removed and is being replaced by a permanent dam of stone masonry, which will be finished this fall. The completion of these two permanent works, the rebuilding of dam at Kaukauna and a few additional repairs to the old work, is all that is contemplated on the Lower Fox for the present. On the Upper Fox nothing of importance, except surveys, was done during the year. Work has been commenced under the appropriation of 1874, as follows, viz: The construction of a new stone masonry lock, near Eureka; the thorough repairs of Winnebago Lock; the deepening and revetting of the Portage Canal, and complete surveys of the Upper Fox. On the Wisconsin River, the construction of wing-dams has progressed in accordance with the plan adopted for the improvement of the river, resulting, wherever the works have been completed, in obtaining an improved channel. This work will be continued during the present working season. Annual appropriations adequate to the magnitude of this work are earnestly recommended.
