when the mills at Neenah, Menasha, Appleton, and Kaukauna had drawn the water so low below the crests of the dams that there was not over 3 feet of water in the channel, and at times there was a depth of but 6 inches on the breast wall of the Kaukauna first lock. On the upper river, on account of the low water during September, the larger boats were obliged to lay up for the remainder of the season.

During the season of 1892 there has been a good navigable depth of water.

Navigation was closed by ice November 18, 1892, and resumed along the line from April 11 to 27, 1893.

During the fiscal year ending June 30, 1893, $59,473.84 was expended and the following work done: A new lock has been built to replace the old one at Portage, Wis.; the channel at Grignon Rapids, 80 feet wide, is about completed; a new middle platform was built in the combined locks at Little Chute with new steel valves, gearing, etc., and minor improvements; a portion of the Kaukauna Canal bank was rebuilt and a portion of the canal bed puddled with clay; two new lockhouses were built, and various repairs made to boats, dredges, and quarter boat.

The dredging done in the Fox River between Green Bay and De Pere is given in the report upon improving Green Bay Harbor.

23. Operating and care of locks and dams on Fox River, Wisconsin.— Under the continuous appropriation for operating and care of canals and other works of navigation, it is proposed to maintain existing navigation by timely repairs to old locks until they are replaced by new, and to continue repairs of works that have already been completed and used, injured by floods or otherwise.

During the fiscal year ending June 30, 1893, $33,551.90 has been expended, the detailed statement appended to the report of the local engineer officer showing the items of expenditure.

24. Removing sunken vessels or craft obstructing or endangering navi gation (wreck of schooner Lumberman 6 miles off Wind Point, Lake Michigan). As the spars of this wreck projected above the lake surface from just above the crosstrees, they were a dangerous obstruction to navigation, as the vessel lay, in 11 fathoms of water, directly on the course between Racine and Milwaukee. On June 23, 1893, the spars and jibboom were removed, and no part of the wreck is now less than 45 feet below the water surface. It is therefore no longer an obstruction to navigation. The cost of the work was $200. (See Appendix K K 24.)

EXAMINATIONS MADE IN COMPLIANCE WITH RIVER AND HARBOR ACT APPROVED JULY 13, 1892.

The preliminary examinations of the following localities, required by act of July 13, 1892, were made by the local engineer, Maj. James F. Gregory, Corps of Engineers, and reports thereon submitted through the division engineer, Col. O. M. Poe, Corps of Engineers:

1. Green Bay, Wisconsin, from light-house to first bridge on Fox River.-Maj. Gregory submitted report of examination under date of August 29, 1892. It is his opinion and that of the division engineer, concurred in by this office, that, excepting that part of the dredged cut included in the general project for improving harbor at Green Bay, the locality is not worthy of improvement by the General Government. The report was transmitted to Congress and printed as House Ex. Doc. No. 22, Fifty-second Congress, second session. (See also Appendix K K 25.)

2. Fox River, Wisconsin, as to necessity and advisability of building a protection wall on the canal at Kaukauna.-Maj. Gregory submitted report of examination under date of August 4, 1892. It is his opinion and that of the division engineer, concurred in by this office, that the improvement proposed is not worthy of being made by the General Government. The report was transmitted to Congress and printed as House Ex. Doc. No. 28, Fifty-second Congress, second session. (See also Appendix K K 26.)

3. Harbor at Stockbridge, on Lake Winnebago, Wisconsin.-Maj. Gregory submitted report of examination under date of August 4, 1892. It is his opinion and that of the division engineer, concurred in by this office, that the locality is not at present worthy of improvement by the United States. The report was transmitted to Congress and printed as House Ex. Doc. No. 78, Fifty-second Congress, second session. (See also Appendix K K 27.)

4. Harbor at Calumet, on Lake Winnebago, Wisconsin.-Maj. Gregory submitted report of examination under date of August 4, 1892. It is his opinion and that of the division engineer, concurred in by this office, that the locality is not worthy of improvement by the General Government. The report was transmitted to Congress and printed as House Ex. Doc. No. 117, Fifty-second Congress, second session. (See also Appendix K K 28.)

IMPROVEMENT OF CHICAGO AND CALUMET HARBORS AND ILLINOIS RIVER, ILLINOIS, AND CALUMET RIVER, ILLINOIS AND INDIANA; ILLINOIS AND MISSISSIPPI CANAL.

This district was in the charge of Capt. W. L. Marshall, Corps of Engineers, having under his immediate orders Lieut. Chester Harding, Corps of Engineers, the entire year, and Lieut. Henry Jervey, Corps of Engineers, since March 12, 1893; Division Engineer, Col. O. M. Poe, Corps of Engineers.

1. Chicago Harbor, Illinois.-The present project was adopted in 1870, and contemplated

a. The formation of an outer harbor or basin, by inclosing a portion of Lake Michigan just south of and adjoining the entrance to Chicago River, for the purpose of increasing the harbor facilities of Chicago.

b. The construction of an exterior breakwater in deep water north of the entrance to Chicago River and about one mile distant, to shelter the approach to the river and outer harbor entrance, and to form a harbor of refuge at the southern end of Lake Michigan.

There has been expended upon this project since 1870 $1,722,158.13, which expenditure has resulted in the completion of the outer harbor, except 267,000 cubic yards of dredging still remaining to be done to attain 16 feet depth of water at low water throughout the required basin; in the completion of the exterior breakwater, 5,413 feet in length; in keeping the entrance to Chicago River, which constitutes the inner harbor of Chicago, dredged; in maintaining the various piers and breakwaters, and in maintaining in serviceable condition the plant pertaining to the work.

During the fiscal year ending June 30, 1893, the work consisted ina. Exterior breakwater.-No work was done upon this construction, it having been completed.

b. Outer basin and south pier, Chicago Harbor.-Contracts were entered into for rebuilding superstructures over 3,725 linear feet of pier work October 28, 1892, and during the fiscal year 179,428 feet, B. M., pine timber and 20,700 pounds drift bolts have been secured in the work over the southerly breakwater outer basin. The work is in progress under contract named, that expires December 1, 1893.

Dredging entrance to Chicago River.-The entrance to Chicago River has been dredged to a depth of 20 feet, and 34,056 cubic yards of the material dredged paid for under contract. This depth exceeds by 4 feet the stipulated depth; the excess was not paid for.

By the end of the next fiscal year the superstructures over the piers of the outer basin and along the entrance to Chicago River will have been renewed, and there is now in need of repair 3,240 linear feet of superstructure over the exterior breakwater built in 1881-1883. The estimate submitted is for this work of maintenance only; the superstructure to be built of timber, cribwork, and stone, that method being as yet more economical than permanent work of stone or concrete, estimating money at 4 per cent interest per annum and the lifetime of timber at 12 years.

There is also a large amount of dredging to be done in the outer harbor, estimated at 267,000 cubic yards, to give 16 feet of water beyond the dock lines. This work is not pressing and should await the settlement of the question as to the disposition of that part of the area inclosed by the United States piers shoreward of the dock line.

The outer basin has never fulfilled the purposes of its construction, except partially during the latter part of the fiscal year, when it has been in use for the purposes of the World's Columbian Exposition, and the expenditures of the Government thereon should await and be based upon its use and value for the public.

In compliance with a requirement in the river and harbor act of July 13, 1892, the engineer in charge submits a report, with estimates, upon improving Chicago River.

2. Calumet Harbor, Illinois.-This improvement is to furnish a safe and practicable entrance to Calumet River and the port of South Chicago by parallel piers 300 feet apart, extending from shore to deep water in the lake, and by dredging between them to 16 feet in depth at low water.

The work commenced in 1870, and at the close of the fiscal year ending June 30, 1893, there had been expended $437,007.06, as the result of which 3,640 linear feet of the north pier and 2,020 linear feet of the south pier have been completed, and 471,364 cubic yards of material dredged, giving a channel 16 feet in depth instead of 7 feet, as originally existed.

The channel is now 250 feet in width, 16 feet in depth below extreme low water in Lake Michigan, and extends from a similar depth in Lake Michigan to the beginning of the 16-foot channel in the Calumet River.

During the fiscal year ending June 30, 1893, a contract was entered into for rebuilding superstructure over 1,600 linear feet of pier work, and for 320 linear feet of sheet piling. All of this work has been completed during the past fiscal year, except the sheet piling; 303,512 feet, B. M., pine timber, and 36,748 pounds iron driftbolts were placed in the work; 51 piles were driven and capped with oak timbers.

One thousand eight hundred and thirty-seven linear feet of superstructure over the piers is in need of repair, a large part of which is in a deplorable state of decay.

The south pier should be prolonged 800 feet, but until the existing work is put in thorough repair it is not advisable to further extend the work.

The estimate submitted is therefore for maintenance and repair only, the project for this harbor, as far as approved, having been completed.

3. Calumet River, Illinois and Indiana.-The object of this improvement as far as projected is to secure a channel 200 feet in width and 16 feet in depth below low-water plane in Lake Michigan, from the mouth of the Calumet River, at Calumet Harbor, Illinois, to one-half mile east of Hammond, Ind., with a view to increasing the facility for handling the commerce of this region, and also to aid in providing means for the better accommodation of much of the commerce of Chicago River, which river is very much crowded. The original depth of navigation in this river varied from 6 to 10 feet.

The various acts of Congress and the limitations made by law upon the expenditure of the appropriations thereby made before work was systematically inaugurated upon this improvement are given in the Annual Report of the Chief of Engineers for the year ending June 30, 1889.

Since the beginning of the improvement there has been removed 1,137,456 cubic yards of material, making a channel 3 miles and 345 feet in length, of which a short portion, where rock and other undred gable material was encountered, is incomplete, there remaining less than 9,000 cubic yards to be removed.

This material can be most economically removed after all of this class shall have been revealed by further work.

The amount expended by the United States to the close of the fiscal year ending June 30, 1893, is $181,868.83, of which $155,772.78 has been expended below the Forks of the Calumet, including $5,000 paid for legal expenses in securing rights of way and releases from damages dup the proposed improvement, required by the act of July 5, 1884, and $2,096,05 100 won between the forks of the Calumet River, and

half mile east of Hammond, Ind.

During the past fiscal year contracts were entered into for dredging 400,000 cubic yards of material below the Forks and 90,000 cubic yards above the Forks, under the terms of the river and harbor act of July 13, 1892. Work is now in progress, but no estimates have yet been paid the contractors, the conditions upon which payments can be made not having as yet been met by them.

The annual fill, due to rains and floods in the Calumet River and the waste due to habitation, rapidly reduces the depths secured by dredging in this river, and it seems advisable that the appropriations made by Congress should be distinctly specified, whether intended to prosecute the work or for maintaining depths in the improved section. Without dredging at frequent intervals the improved channel will revert to the original discharge area or capacity.

4. Illinois River, Illinois.-The present project contemplates the extension of the work heretofore done by the State of Illinois, from the mouth of Copperas Creek to the Mississippi River, a distance of about 135 miles, which project includes the building of two locks 350 feet long between miter sills, 75 feet in width of lock chamber, with 7 feet of water over the miter sills at low water level of 1879, and dredging the channel where necessary to attain 7 feet depth at low water in the pools thus created.
