3. Bridge at Glasgow, Missouri.-A Board of Engineer Officers was convened to consider and report upon the plan and location of a bridge proposed to be erected over the Missouri River at Glasgow, Mo., by the Kansas City, Saint Louis and Chicago Railroad Company, which had been submitted for the approval of the Secretary of War, in accordance with the act of Congress of March 13, 1878. For the report of the board, see Appendix X 2. 4. Bridge on the Mississippi, at Fort Snelling, Minnesota.-The "act making appropriations for sundry civil expenses of the government for the fiscal year ending June thirtieth, eighteen hundred and seventynine, and for other purposes," approved June 20, 1878, made provision for the "construction and completion of a free wagon-bridge, with stone abutments, or stone and iron abutments, and iron superstructure, across the Mississippi River, at or near Fort Snelling," and appropriated the sum of $65,000 to aid in the same. The plans and specifications of the substructure were approved by the Secretary of War, and the officer of engineers stationed at Saint Paul was instructed to take such supervision of the bridge during its construction as will enable him to determine whether the approved plans and specifications are faithfully carried out. 5. Report upon bridging the Mississippi River between Saint Louis, Missouri, and Saint Paul, Minnesota.-The river and harbor act of June 23, 1866, made provision for examining and reporting upon the subject of constructing railroad-bridges across the Mississippi, between Saint Paul, Minn., and Saint Louis, Mo., upon such plans of construction as would offer the least impediment to the navigation of that river. This subject was, at the time, assigned to Maj. G. K. Warren, Corps of Engineers, but his report thereon has been delayed from the pressure of other important duties. Since the date of the act there has been an almost continued increase of new and important data. The surveys which Major Warren had caused to be made did not include the bridges and changes made since 1870, but surveys having since been made of those bridges, and much additional information obtained, the report was completed and submitted to this office in March last, and transmitted to the Senate at its last session and printed in Senate Executive Document No. 69, Forty-fifth Congress, second session. It is reprinted as Appendix X 3 of this report. LAKE HARBORS AND RIVERS. IMPROVEMENT OF HARBOR AT DULUTH, MINNESOTA, AND OF THE ENTRANCE TO SUPERIOR BAY, LAKE SUPERIOR. Officer in charge, Maj. F. U. Farquhar, Corps of Engineers. 1. Improvement of harbor at Duluth, Minnesota.-A channel has been dredged by contract through the bar on the north side of the dike, and the dredging in the inside harbor continued. During the present season it is proposed to continue the dredging and to repair the piers of the canal. To continue this work economically the officer in charge recommends an annual appropriation of $50,000 until the work is completed; also, that $10,000 additional should be made available for repairs of piers.

Improvement of natural entrance to the Bay of Superior.-A brush and stone protection was built at "the opening," on Minnesota Point. The officer in charge recommends that the beach protection at the lower end of Minnesota Point be continued toward the light-house and some small repairs to the piers be made; also, that $10,000 be appropriated for such repairs to the superstructure of the piers as may be necessary.

(See Appendix Y 2.) HARBORS ON LAKE SUPERIOR (EXCEPT DULUTH AND SUPERIOR CITY), ON GREEN BAY, AND ON THE WESTERN SHORE OF LAKE MICHIGAN, NORTH OF MILWAUKEE, WISCONSIN. Officer in charge, Maj. Henry M. Robert, Corps of Engineers. 1. Improvement of Ontonagon Harbor, Michigan.-Superstructure was finished over 10 cribs. One crib was refilled and replanked on the east pier, and refilling and riprapping were done on the west pier. Extensive repairs are now in progress, and 6 cribs will be placed in extension of the piers this season. It is proposed to continue the pier extension as fast as the appropriations will admit of. The piers are now each 1,300 feet long, the full length planned being 2,500 feet each. This is an important work, being the only available harbor of refuge on a long stretch of coast. 178, 170 00 Amount (estimated) required for completion of existing project.. Amount that can be profitably expended in fiscal year ending June 30, 1880.. 50,000 00 (See Appendix Z 1.) 2. Improvement of Eagle Harbor, Michigan.-The work of blasting a channel acoss the ledge of rock which obstructs the entrance to this harbor, commenced in 1875, was finished, and the broken rock removed by dredging. The work was done by hired labor at an actual cost of $10.83 per cubic yard in place, or $6.08 per yard in scows, after two contractors had attempted it and failed, though getting $40 and $58 per cubic yard, respectively. Though the project contemplates a further expenditure of $178,362, the officer in charge does not think so large an outlay necessary to the safe use of the harbor, and there will be placed this season two guiding cribs to mark the channel, after which the only work done will be the refilling and riprapping of these cribs, for which $2,000 will be required, the amount in which the last appropriation fell short of the officer's estimate.

Improvement of Marquette Harbor, Michigan.-Slight repairs were made on the breakwater, and an examination was made to ascertain the amount of stone required for refilling, which is estimated at 1,000 cords. Of this quantity, about 400 cords will be put in during the present season, and the remainder, with such other repairs as are always needed to this exposed work, should be done during the fiscal year 1879-'80, for which the sum of $5,000 will be required. This breakwater was finished at a cost nearly $79,000 less than the estimate, and should be extended 400 linear feet, which would cost $68,000. Amount that can be profitably expended on repairs in fiscal year ending (See Appendix Z 3.) 5,000 00 4. Improvement of Menomonee Harbor, Michigan and Wisconsin.-Five new cribs were built and placed in extension of the piers, and 3,723.8 cubic yards of material were dredged from the bar, at a cost of ten cents per cubic yard; a resurvey of the channel was made, showing a 14-foot channel to the heads of the piers and for 1,000 yards up the river. Three new cribs will be placed this season in extension of the piers and superstructure built over those placed last season. Further extension of the same work is proposed for the fiscal year 1879–280. 69, 000 00 Amount (estimated) required for completion of existing project...... Amount that can be profitably expended in fiscal year ending June 30, 1880. (See Appendix Z 4.) 40, 000 00 5. Improvement of Green Bay Harbor, Wisconsin.-Dredging on the line of previous work in the channel leading in from Green Bay was done to the amount of 39,282.5 cubic yards, which were removed at a cost of 12 cents per cubic yard. A resurvey of the channel 10,000 feet long was made through ice, to determine the proper location of future work. During the present season dredging in continuation of the im provement will be carried on as far as funds will permit. The same work is proposed for the next fiscal year, with such repairs as the piers at Grassy Island may require. The importance of this work is sufficiently indicated by its position at the mouth of Fox River, it really forming a part of the Fox and Wisconsin River improvement.

Harbor of Refuge at entrance to Sturgeon Bay Canal, Wisconsin.— The outer ends of the pier were refilled as far as the small sum available would permit and a set of soundings taken in the harbor. No work had been done since 1874. During the present season 14 cribs will be placed in extension of the piers and the old piers repaired. During the fiscal year 1879-'80 it is proposed to complete the pier extension and to commence dredging in the harbor. The officer in charge refers to the vigorous prosecution of the canal work during the past year, and calls attention to certain defects in the construction of the canal and in the legislation of Congress granting the land-grant under which it is constructed, and to the relation which this work bears to the government harbor. He recommends that future appropriations be worded as the first were, the phraseology having been changed in the last appropriation bill; and expresses a belief that, although the canal may possibly be abandoned by the company, the government should finish the harbor at its entrance. 100, 000 00 60, 000 00 Amount (estimated) required for completion of existing project.... Amount that can be profitably expended in fiscal year ending June 30, 1880. (See Appendix Z 6.) 7. Improvement of Ahuepee Harbor, Wisconsin.-Superstructure over the 7 cribs of 1875, in progress at the date of the last annual report, was finished, and 1,100 linear feet of plank walk laid on the piers. The rock blasted from the river-bed was removed by the United States dredge, and 100 cords of the same was placed in the piers. The ice during the winter was not in condition to admit of work as expected, but the drilling and blasting were recommenced in June last, and will be prosecuted through the present season. Continuation of the same work is proposed during the fiscal year 1879-'80, with the repairs necessary for the preservation of the piers. July 1, 1877, amount available.... Amount appropriated by act approved June 18, 1878...... July 1, 1878, amount expended during fiscal year.

Amount that can be profitably expended in fiscal year ending June 30, 1880. 25,000 00 (See Appendix Z 7.) 8. Improvement of Two Rivers Harbor, Wisconsin.- Superstructure and plank walk over the 6 cribs of 1875, in progress at the date of the last annual report, was completed. Three hundred linear feet of pier was decked and soundings taken through the channel and in the vicinity of the bridge pier. During the present season sand-proof lining will be built on the pile piers and some dredging done between the piers. During the fiscal year 1879-80 the operations contemplated are the further extension of the piers and dredging between them. This harbor has never been opened to the local commerce of the place, the work thereon not being sufficiently advanced. The private bridge pier has been used by vessels to the present time, and as accretions are rapidly forming around it, it becomes advisable to complete the harborwork as soon as possible. Amount (estimated) required for completion of existing project..... Amount that can be profitably expended in fiscal year ending June 30, 1880. (See Appendix Z 8.) = 145, 588 80 40, 000 00 9. Improvement of Manitowoc Harbor, Wisconsin.-The repair-work in progress at the date of the last annual report was completed and a series of soundings taken through the channel. During the present season four new cribs will be placed, the piers will be refilled, and repairs made as necessary. During the fiscal year 1879-80 it is proposed to extend the piers to 18 feet water, and do such dredging as may be necessary. If the whole amount estimated for that year be appropriated, this harbor can be finished within the estimated cost, notwithstanding that the small appropriations have necessitated a good deal of repairwork. This port, being the most frequently sought in stormy weather on the northwestern shore of Lake Michigan, should be completed at as early a day as possible. Amount (estimated) required for completion of existing project..... Amount that can be profitably expended in fiscal year ending June 30, 1880. (See Appendix Z 9.) 21, 682 54 21, 682 54 10. Improvement of Sheboygan Harbor, Wisconsin.-The cost of this harbor has so far exceeded the estimate by over $8,000, but the work since 1875 has been almost wholly repairs to the piers. These repairs were continued from November to May, and will be prosecuted during the present season and during the fiscal year 1879-'80. It is estimated that they will cost $12,000 to complete, of which $4,000 was appropriated this year. It became necessary to dredge out the channel this last spring, an unusually heavy gale having moved a large quantity of beach sand into it. The work was done by the United States dredge, which was moved for |
