Under contract 401 linear feet of the south pier was rebuilt above the water-line.

The total amount expended to June 30, 1889, is $298,898.89, and has resulted in the construction of two piers 1,970 and 1,900 feet long, 228 feet apart at the shore-line, and 250 feet at the outer ends, and in the dredging of 184,997 cubic yards of material.

It is proposed to expend the appropriation asked for in rebuilding the inner ends of the piers above the water line.

12. Sheboygan Harbor, Wisconsin.-Previous to the improvement of this harbor the natural channel had a depth not exceeding 4 feet on the bar at the entrance to the river.

The project for the improvement of this harbor was adopted in 1852 and had for its object the formation of a 12-foot channel entrance to the mouth of the Sheboygan River. This was modified in 1873 so as to secure a deeper channel by further pier extension and dredging. Both projects were completed within their estimated cost and a channel was formed 100 feet wide with a depth of 15 to 16 feet between the piers. The existing project was adopted in 1881, its object being to deepen the channel still further by extending the piers to the 20-foot contour in the lake and dredging to a depth of 18 feet between their outer ends, the depth decreasing to 14 feet at the shore line. There is now a navigable channel with a depth of 14 feet.

During the fiscal year ending June 30, 1889, 20,150 cubic yards of material was removed from the channel by a Government-dredge.

At the close of the fiscal year the south pier was being extended 200 feet by contract.

The total expenditures to June 30, 1889, have amounted to $289,770,86, and have resulted in the construction of two piers 2,044 and 2,260 feet long, respectively, built of cribs (except less than 300 feet at the shore end), of widths of from 14 to 20 feet, and in dredging 207,193 cubic yards of material from the channel.

The only means of securing a permanent channel is by rapid extension of the piers to deep water; hence a liberal appropriation is urged as a matter of economy and of necessity to the commerce of this important harbor.

13. Port Washington Harbor, Wisconsin.-The present project for the improvement of this harbor, adopted in 1859 and modified in 1870 and 1876, was for the formation by dredging of two interior basins, having a combined area of about 53 acres, with a depth of 12 feet, and a channel of the same depth connecting them with the lake, the channel entrance to the basins to be north of the mouth of the Sauk River, inclosed between two piers.

The natural channel at the mouth of the Sank River was narrow, and at the shoalest point had a depth of but 1 foot.

At the close of the fiscal year ending June 30, 1889, dredging was being done at this harbor, and on the above mentioned date 3,510 cubic yards of material had been removed.

The amount expended to June 30, 1889, is $169,161.54, and has resulted in the construction of a north and south pier 920 and 1,226 feet long, respectively, with 400 feet revetment along the north bank of the river, extending to the inner end of the south pier; in the formation of two interior dredged basins of 23 and 3 acres, respectively, with an average depth of about 9 feet in the north and 8 feet in the west basin, and in making a navigable channel between the piers of 11 feet. It is proposed to extend the appropriation asked for in completing the south pier and maintenance of works.

14. Harbor of refuge at Milwaukee Bay, Wisconsin.-In charge of Capt. W. L. Marshall, Corps of Engineers, until September 19, 1888.-The proj ect for the work was approved in 1881, and contemplated the formation of an artificial harbor by inclosing a portion of Lake Michigan within an outer breakwater of crib-wo: k upon a stone foundation. This harbor will furnish 417 acres of safe mooring ground beyond the 18-foot contour and about twice this area beyond the 12-foot contour.

Work began in 1881, and up to June 30, 1889, there has been expended $360,812.22, resulting in the completion of 3,550 linear feet of the substructure of the breakwater, over which 3,100 linear feet of superstructure has been built.

During the fiscal year ending June 30, 1889, 250 feet of substructure. has been built.

The breakwater when completed will be 7,250 feet in length. There remains, then, to be constructed 3,700 linear feet of substructure and 4,150 linear feet of superstructure to complete the work.

The funds asked for are to be applied to the extension of the breakwater.

The harbor is now used to a limited extent as a shelter from northeast storms. Its value will rapidly increase as the east arm is extended. July 1, 1888, amount available

15. Milwaukee Harbor, Wisconsin.—In charge of Capt. W. L. Marshall, Corps of Engineers, until September 19, 1888. The present project was adopted in 1852, and was directed to securing 12 feet of water.at the entrance to the river and to protecting this channel by parallel piers. Since that date a channel, 18 feet in depth and of sufficient width, has been formed by extending the piers and dredging. The project has been completed, and consequently the only expenditures now demanded are for the maintenance of the piers by timely repairs and the depth of the channel by dredging.

The original depth of water at the mouth of the river was not more than 34 feet.

The United States has expended on this harbor up to June 30, 1889 $294,103.87, in addition to $321,355.66 by the city of Milwaukee.

During the fiscal year ending June 30, 1889, 340 linear feet of super structure over the outer section of the south pier has been cut down and rebuilt.

The stone superstructure of the north pier and the concrete paving need repairing. Repairs are also needed at the inshore ends of both piers No dredging has been done at this harbor since 1880, and the channel ha narrowed and shoaled somewhat. It will require the removal of som 30,000 cubic yards of material to restore the channel to its projecte dimensions.

It is intended to apply the appropriation asked for to the above mentioned repairs and dredging.

16. Racine Harbor, Wisconsin.-In charge of Capt. W. L. Marsha Corps of Engineers, until September 19, 1888. The entrance to th harbor originally varied in depth from absolute closure after storms about 6 feet.

The original project was adopted in 1843 and contemplated a channel 12 feet deep. In 1866 the project was modified to providing a channel 15 feet deep.

There has been expended on this harbor up to June 30, 1889, $238,706.55, resulting in a north and south pier, 1,460 and 1,070 feet in length, respectively, and a channel 16 feet in depth.

During the past fiscal year the channel, which had shoaled to barely123 feet, was dredged out to 16 feet, thus restoring it to the projected dimensions, 36,356 cubic yards of material being removed by contract. The constant shoaling at the entrance to this harbor shows that the piers will have to be extended several hundred feet in order to maintain the intended depth of 16 feet. Some 500 feet of the superstructure of

the piers needs rebuilding.

It is proposed to expend the appropriation asked for in the above mentioned repairs and pier extension.

17. Kenosha Harbor, Wisconsin.-In charge of Capt. W. L. Marshall, Corps of Engineers, until September 19, 1888. The plan of improvement by parallel piers and dredging was adopted in 1852, and was first directed to securing a channel 12 feet deep. This was modified in 1866 so as to secure a channel 15 feet deep. The original depth was 4 feet or less; sometimes the mouth of Pike Creek was entirely closed.

In 1875 and 1876 this harbor was dredged to 15 feet, but the appropriations have been insufficient to maintain this depth, so that the periodical dredging has only provided an available channel of about 12 feet. During the fiscal year ending June 30, 1889, nearly 25,000 cubic yards of material has been dredged from the channel between the piers, by contract, thus restoring the channel to a uniform depth of 15 feet. The contract was completed November 30, 1888, and soundings made in May, 1889, showed that a bar had reformed across the front of the harbor with a least depth of 9.8 feet. Arrangements have been made for removing this bar.

The only method of preventing this reforming of the bar is to extend the piers, and it is proposed to expend the appropriation asked for in this pier extension and in repairs to superstructure.

There has been expended on this harbor up to June 30, 1889, $226,596.71, resulting in the construction of two piers, north and south, being respectively 1,600 and 800 feet in length, and a channel of varying depth. July 1, 1888, amount available.....

18. Waukegan Harbor, Illinois. In charge of Capt. W. L. Marshall, Corps of Engineers, until September 19, 1888.-The present project was adopted in 1880, and, as since modified, consists in excavating a small basin in the low ground between the lake and the bluffs to form the harbor, and in dredging an entrance between piers from the lake to the basin.

During the fiscal year ending June 30, 1889, by hired labor the south pier was extended 248 feet. A contract was entered into for dredging the entrance channel and interior basin and on the above-mentioned date 17,805 cubic yards of material had been removed.

There has been expended on this harbor up to the close of the fiscal year $100,765.37, resulting in the construction of a total length of pile pier-work of 2,284,5 feet and the removal of the 17,805 cubic yards of material.

The prolongation of the fore-shore on the north side of the harbor will necessitate a material extension of the entrance piers, and it is proposed to expend the appropriation asked for in pier extension and the further prosecution of the approved project.

19. Fox and Wisconsin Rivers, Wisconsin.-In charge of Capt. W. L. Marshall, Corps of Engineers, until September 19, 1888. The works for the improvement of the Fox and Wisconsin rivers were purchased by the United States from the Green Bay and Mississippi Canal Company in 1872. These works were all, except one stone lock, temporary struct ures, all of them in bad condition. There was no low-water navigation on the Upper Fox, and on the Lower Fox navigation was uncertain.

For the Fox River.-The adopted project contemplated the replacing of the temporary structures with permanent works, the construction of five additional stone locks on the Upper Fox, and widening and deepening the channels throughout the river and canals to 6 feet depth and 100 feet width.

For the Wisconsin River.-The method adopted has been to contract the channel-way by wing dams of brush and stone, to give increased depth by concentrating the water and by scour due to the increased currents. The estimate, including the Wisconsin River, made in 1874
