Amount (estimated) required for completion of existing project harbor acts of 1866 and 1867. (See Appendix H H 2.) 3. Harbor at Duluth, Minnesota.-The original project for the improvement of the harbor, adopted in 1871, consisted 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 project 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, dredging an inner harbor to accommodate vessels drawing 16 feet of water, a channel parallel with the Park Point dock line 100 feet wide, a channel east of Rice Point 200 feet wide and 17 feet deep, and a channel along the north shore of St. Louis Bay 200 feet wide, 17 feet deep. The total amount expended on the harbor to June 30, 1891, is $590,732.98, of which $270,651.81 was expended prior to the adoption of the present project; the amount expended under the present project to the same date is $320,081.17. The work has resulted in increasing the dredged area of the 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 on the north side of St. Louis Bay. The season's work gave this channel a width of about 100 feet between 15-foot curves. The amount of material dredged was 295,177.3 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 H H 3.) 4. Harbor at Superior Bay and St. Louis Bay, Wisconsin.-Orig inally 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 had been expended to June 30, 1891, the sum of $182,455.43. Operations during the past year have consisted in widening and straightening the channel leading from the entry to Connor Point, widening the West Superior Channel in St. Louis Bay in the vicinity of Connor Point and the Northern Pacific Railroad Bridge, and extending it about 2,500 feet towards the natural deep water at Grassy Point. The entry piers need extensive repairs, particularly the superstruc ture. The entry and dredged channels have full 16 feet depth.

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, was 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.

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 breakwater, 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. During last year 1,080 feet was added to the breakwater, making its present length. 5,680 feet, the breach in Chequamegon Point was closed with a brush and stone dike, and the old part of the breakwater repaired. No dredging has yet been done. The amount expended during the year was $59,400.87. The total amount expended under approved project to June 30, 1891, was 77,737.80. The breakwater, 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. Amount (estimated) required for completion of existing project................. 142,500. 00 Submitted in compliance with requirements of sections 2 of river and harbor acts of 1866 and 1867. (See Appendix H II 6.) 7. 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 Superior, 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 mean time, 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 consider ation 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; a dredged channel through the bar and the remaining 150 feet of superstructure on the west pier were completed last season. At the close of work the channel was left with 16 feet of water in it, but it is presumed the river will at least partially fill this up during this season's freshets. The amount expended during the fiscal year just closed was $9,585.39. The total cost of the improvement to June 30, 1891, was $302,730.76. July 1, 1891, balance unexpended...

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, 1892, was $94,713.67, and has resulted in carrying out the above proj ect, 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 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. There was finished 60 feet of crib work and 180 feet of riprap foundation. The contract in progress at date of last annual report extended the breakwater 240 feet, leaving 700 feet to be built to complete it. The breakwater in its present condition gives much protection to the harbor. The amount expended during the fiscal year ending June 30, 1892, was $29,798.60. The total cost of the work to June 30, 1891, was $349,770.58. July 1, 1891, balance unexpended.... June 30, 1892, amount expended during fiscal year.

(See Appendix H H 9.) 10. Harbor of refuge at Grand Marais, Michigan.-Originally the entrance to this harbor was obstructed by a bar, having but about 6 feet depth of water upon it. The project for its improvement, adopted in 1881, has for its object a deep and safe channel into the harbor, making it a harbor of refuge. This object is to be attained by building parallel piers projecting into the lake, and dredging out a channel between them, connecting the deep water of the lake with that of the harbor. The proposed length of each pier was 1,800 feet. The west pier has now reached a length 1,406 feet, and the east pier 853 feet. A channel 150 feet wide and 17 feet deep was dredged out between the piers, but had shoaled until it had but from 7 to 9 feet depth, when work begun last season. The total amount expended under approved project to June 30, 1891, was $180,880.80. The amount expended during the year ending June 30, 1892, was $45,727.26. The outer ends of the canal piers were repaired, new shore ends and spurs put in, the old shore ends remodeled, and a channel 175 feet wide and 17 feet deep dredged through between the piers.
