Harbor at Agate Bay, Minnesota.-This is a shipping port for iron ore, and when the breakwater piers are built will form a harbor of refuge. It is 27 miles east of Duluth. The project for the improvement of this harbor was adopted in 1887, and contemplates the erection of two piers projecting from the headlands of the bay and inclosing about 109 acres of water area. The eastern pier is to be 1,000 feet long and the western one 900 feet. Work upon the east pier was commenced in 1887 and at the date of the last annual report 550 feet of it had been built. The contract now in progress will complete 200 feet more. The beneficial effects of the work done are greater than were antici pated, the tranquillity of the harbor has been greatly augmented, and vessels are no longer obliged to put to sea during storms, but can find saftety under the shelter of the break water.

(See Appendix K K 2.) 3. Harbor at Duluth, Minnesota.-The original project for the improvement of the harbor, adopted in 1871, cousisted of a breakwater in Lake Superior, outside of Minnesota Point, in continuation of one already commenced by the Northern Pacific Railroad Company. This breakwater was destroyed by a storm in 1872 and abandoned. In 1873 Congress provided for maintaining the canal through Minnesota Point, which had been constructed by the city of Duluth, and for dredging channels in Superior Bay to the Duluth docks. Work under this project was continued until 1881, at which time the piers of the canal had been repaired and somewhat extended, a harbor basin dredged of moderate capacity, and a narrow channel dredged in Superior Bay from Duluth to deep water at Connor Point. The amount expended under this projoct was $270,651.81. The present project was adopted in 1881 and modified in 1884 and 1888, the object being to preserve the piers bordering the canal, dredg ing an inner harbor to accommodate vessels drawing 16 feet of water, channel parallel with the Park Point dock line 100 feet wide, channel east of Rice Point 200 feet wide and 17 feet deep, and channel on north shore of St. Louis Bay 200 feet wide, 17 feet deep. The amount expended under present project to June 30, 1890, was $538,533.70, and has resulted in increasing the dredged area of harbor basin to about 104 acres, exclusive of private dredging, removing shoals from area previously dredged, giving the whole dredged basin a minimum depth of 16 feet, deepening the Blast Furnace Channel to a like depth, maintaining the canal piers, and commencement of channels east of Rice Point and on north shore of St. Louis Bay. The Blast Furnace Channel was abandoned upon the establishment of the new dock lines. Work during the past year consisted in enlarging the new channel east of Rice Point to a width of 110 feet throughout its length of 8,460 feet and beginning the enlargement of the channel on the north side of St. Louis Bay. This season's work is expected to give the latter channel a width of about 100 feet. The amount of material dredged from the former channel was 234,366.4 and from the latter 90,530,9 cubic yards. The canal piers are in a poor condition, and the entire work needs to be replaced with an improved and permanent structure. The harbor basin and connecting channels will eventually require deepening to 22 feet. The channels recently commenced should be completed at an early date, both for the accommodation of commerce and as a matter of economy.

(See Appendix K K 3.) 4. Harbor at Superior Bay and St. Louis Bay, Wisconsin.-Originally the natural entry to Superior Bay was obstructed with shifting bars having at most but 9 feet depth of water over them. The citizens of Superior attempted to remedy this by constructing piers to confine the outflowing waters of the bay, and this work was taken up by the United States in 1867, and has successfully maintained since then a ruling depth of 16 feet between the piers. The piers are 350 feet apart, and a good deal of dredging has been necessary to obtain the required depth between them and the channels leading to Connor Point and the Quebec Dock and a new connecting channel in St. Louis Bay. The original project of 1867 has, therefore, been modified from time to time to meet the needs of the rapidly increasing capacity of the vessels visiting this port, the last modification being made by act of Congress approved August 5, 1886, which added improvement of channel in St. Louis Bay. In carrying out the original project with modifications there has been expended to June 30, 1890, the sum of $495,046.59. Operations during the past year have consisted in dredging a channel through the bar at the mouth of Nemadji River, beginning the widening and continuing the extension of channel in St. Louis Bay. The entry piers need extensive repairs, particularly the superstructure. The entry and dredged channels have full 16 feet depth. July 1, 1890, balance unexpended ....

(See Appendix K K 4.) 5. Minnesota Point at Superior, Wisconsin.-The object of this work is to protect the channel from the old entrance to Superior Bay from drifting sand and to prevent the Lake from cutting through Minnesota Point into the bay at a low place known as "The Opening." The project approved October 23, 1890, is for a double post and board fence of a total length of 1,216 feet filled in with brush and stone to catch the sand. The fence was completed May 27, 1891, and is accomplishing the purpose for which it was built. Amount appropriated by act approved September 19, 1890. July 1, 1891, balance unexpended. (See Appendix K K 5.) $4,895.00 4,526.59 368.41 6. Harbor at Ashland, Wisconsin.-Ashland Harbor is located at the head of Chequamegon Bay, and originally had no protection from the waves which rolled into the bay or from the waves generated within the bay itself by storms. The approved project is for the construction of a pile, slab, and rock break water 8,000 feet long northeast of the town, and for dredging a channel in front of the wharves of the city to accommodate vessels drawing 16 feet of water. During the season of 1889 a portion of the breakwater 4,650 feet in length was completed, but a severe storm in November the same year destroyed the outer 50 feet and the slab filling settled in some places. At the date of the last annual report repairs were under way and were completed early in the season. The contract now in progress will extend the breakwater 1,080 feet and close the breach in Chequamegon Point with a brush and stone dike. No dredging has yet been done. The amount expended during the year was $17,451.24. The total amount expended under approved project to June 30, 1890, was $66,398.73. The break water, though of insufficient length to give full protection to all the wharves of the city, has nevertheless had a marked influence in improving the tranquillity of the harbor.

Harbor at Ontonagon, Michigan.-The entrance to Ontonagon River, which forms the harbor, had but 7 feet depth in 1867, at which time the project for securing 12 feet depth by building parallel piers on either side of the mouth, extending to the 18-foot curve of depth in Lake Su. perior, and dredging a channel between the piers, was adopted. The west pier has reached a length of 2,675 feet, and is very nearly out to the 18-foot curve of depth, as proposed. But this curve has advanced in the meantime, owing to the very considerable volume of sand carried into the lake by the river, and since it appears probable that the advance of the bar will keep pace with the extension of the piers, unless a very considerable extension is made at once, a consideration scarcely to be expected, it does not appear that economic considerations would justify any further extension of the piers at present. The east pier is 2,315 feet in length. For a time it seems that better results will be secured, after the piers are put in repair and the superstructures to outer cribs of west pier are finished, by dredging across the bar after each spring freshet. The channel between the piers has kept a depth of over 12 feet and a dredged channel through the bar has just been completed. The superstructure on the remaining 150 feet of the west pier is in progress and will be completed this season. The amount expended during the fiscal year just closed was $952.17. The total cost of the improvement to June 30, 1890, is $296,157.80.

(See Appendix K K 7.) 8. Eagle Harbor, Michigan.-Previous to the improvement of Eagle Harbor the entrance was obstructed by a rocky reef, with 8 feet of water over the shoalest part. The project for the improvement of this harbor was adopted in 1866 and modified in 1868, 1874, and 1878. The plan, as finally carried out, consisted in blasting and dredging through the rocky ledge a channel 130 feet wide and 14 feet deep, and marking it with two guiding cribs, one on each side of the channel, and the removal of a number of bowlders. The amount expended to the close of the fiscal year ending June 30, 1891, was $94,513.67, and has resulted in carrying out the above project, the work having been completed in 1879, and meeting the present demands of commerce. No appropriation is asked for this harbor, as the funds available will probably be sufficient to keep the work in good order for several years longer.

Harbor at Marquette, Michigan.-Originally this harbor afforded no protection to vessels from the easterly or northeasterly storms, and in 1866 a project was approved for the construction of a breakwater composed of cribs filled with rock, and projecting from the shore into the bay a distance of 2,000 feet. This pier was finished practically as projected in 1875, but since its commencement extensive repairs have been made to the superstructure. As the timber composing the superstructure has been in place far longer than supposed probable, it is essential that it be replaced by more durable material. A project for a concrete superstructure was approved in February, 1890. Its estimated cost is $232,936.71. In the river and harbor act of August 11, 1888, provision was made for the extension of the breakwater. In 1889 work upon the first 180 feet of this extension was commenced, but owing to the violence of storms towards the end of the season, before the work was finished, a greater portion of the crib substructure was ruined. There was finished but 60 feet of crib work and 180 feet of riprap foundation. The contract now in progress will extend the breakwater 240 feet. The amount expended during the fiscal year ending June 30, 1891, was $2,340.96. The total cost of the work to June 30, 1890, was $347,579.62.
