Manistee Harbor, Michigan.-Three hundred and fifty feet of inside revetment have been built here, after cutting off a sharp bend in the river, on the south side. During the next year 355 feet of revetment will be built on the north side, facing a sand-bank which is much exposed to wash to the detri ment of the channel; also 140 feet of revetment on the south side in continuation of the work of last season. To carry the piers into the lake to the depth of 16 feet water will require the extension of the north and south piers 650 and 750 feet, respectively, or the addition of 28 cribs, each 50 feet long; which, at $4,000 each, will amount to $112,000; of which sum $50,000 can be profitably expended during the next fiscal year.

Ludington Harbor, Michigan.-Six 50-foot cribs were placed in extending south pier 300 feet. During the winter the outer crib lightened and rolled into the channel, leaving the pier extension 250 feet for the year's work. During this season it is proposed to remove the old slab-revetment and sand-bank on the south side, revetting the face exposed; and to replace the crib mentioned above. Ten thousand dollars is thought by the officer in charge to be necessary to dredge the channel and complete the improvements for some time to come.

Pentwater Harbor, Michigan.-The top timbers and entire filling of the 300 feet of revetment left incomplete at date of last report have been finished. Two cribs (100 feet) were placed in extension of north pier, and the superstructure built over them. Some necessary repairs will also be made this season to the filling at several places in both piers. No appropriation is asked. Balance in Treasury of United States July 1, 1873..

White River Harbor, Michigan.-During the last fiscal year the work at this harbor has been limited to making repairs, filling piers with brush, slabs, and stone ballast. The present year the south pier will be extended 50 feet, (1 crib,) and slabs and stone will be added to the filling in the old work, while a por tion of the appropriation will be held over for dredging the channel, should such contingency occur. To carry out the south pier into 16 feet water and the north pier into 11 feet, which is requisite to secure a permanent improvement, will cost $44,525.60, to which should be added $5,000 for dredging.

Muskegon Harbor, Michigan.-No appropriation was made for this harbor last year. The work under a former appropriation, 350 feet of revetment on south side and 250 feet on north side, was completed September 30, 1873. With the $10,000 appropriated by act of June 23, 1874, the south pier will be extended 50 feet, (1 crib,) and about 135 feet of pile-revetment will be added to the north side, eastward of the Government work, where the old slab-pier was burned and where a breach threatened. Forty-six thousand dollars is asked to continue pier-extension, which the large commerce of this place demands. Amount in hands of officer and subject to his check..

Grand Haven Harbor, Michigan.-Early in the past year some very needed repairs were put upon the south pier. Two thousand one hundred feet of pile-work for north pier and revetment was put under contract and nearly completed. The present year the north pier will be extended 300 feet, (six cribs)— probably as far as it will need to go for some time to come-and 500 feet of pile-revetment will be constructed on the south side eastward of the former work. The harbor is by far the best on this shore. It is 400 feet wide, with 20 feet of water. No appropriation is required for the next fiscal year. Balance in Treasury of United States July 1, 1873..

Black Lake Harbor, Michigan.-Four hundred feet of pile-revetment have been constructed on the south side during the year, and much of the filling of the old work renewed. During the present season the piers will be extended, the south 100 feet and the north 50 feet, possibly 100 feet. To secure permanency to the present good condition of this harbor, the piers should be extended to 15 feet of water, and $35,000 is asked to continue this work of extension.

Saugatuck Harbor, Michigan.-The contract made under the last appropriation was annulled for cause, and the work of building 400 feet of north pier is progressing by hired labor. It is about one-half completed. A wing-dam 243 feet long was built in the river to direct the current. It is proving of great benefit, apparently removing the agency which tended to undermine the revetment, and is depositing material where it is so much needed, and where the revetment has almost given way. This year it is intended to build about 400 feet of pile-work, connecting the north pier with the shore. Fifteen thousand dollars is asked to continue the improvements.

ENLARGEMENT OF ST. MARY'S FALLS CANAL, AND IMPROVEMENT OF THE ST. MARY'S RIVER-HARBORS ON LAKES HURON AND ST. CLAIR— ST. CLAIR FLATS CANAL AND DETROIT RIVER. Officer in charge, Maj. G. Weitzel, Corps of Engineers, with Capt. A. N. Lee, Corps of Engineers, under his immediate orders. 1. St. Mary's Falls Canal.-During the year the purchase of land required for the enlargement of the canal has been completed. The winter was very favorable for work, and much has been accomplished. The excavation for the deepening and widening of the greater portion of the old prism and the pier-revetment for the side of the same were nearly completed, as also the lock-pit for the new lock. It is extremely important and pressing that there should be no delay in constructing the new locks, as if anything should happen to prevent the use of the old ones, the effect on commerce would be ruinous. The original estimate of the cost of these locks was $1,159,330. Of this sum there remains $560,000 to be appropriated, and at least $300,000 of this should be made available for the fiscal year ending June 30, 1876.

St. Mary's River, Michigan.-A survey of the Hay Lake Channel has been made, to form an estimate of the cost of its improvement. By this channel the distance to the Sault St. Mary's Canal is shortened eleven miles, and vessels would be enabled to navigate it at all hours, the Lake St. George Channel, now used, being only practicable by day. The opening of this channel, however, involves the serious expense of rock-excavation through West Neebish Rapids. (See Appendix D 2.) 3. Cheboygan Harbor, Michigan.-The operations here have consisted in continuing the dredging of a channel 13 feet deep across the bar, under the appropriation of March 3, 1873. Seventy-six thousand nine hundred and fifty-five cubic yards were dredged during the fiscal year. The work already done has been of much benefit to the general commerce of the lakes. The officer in charge submits an estimate of $60,000 for the next fiscal year.

Mouth of Au Sable River, Michigan.-The operations during the year consisted in dredging a channel 10 feet in depth across the bar of the river and keeping existing structures in repair. Attention is again called by the officer in charge to the encroachments upon the channel of the river by private parties, which tend to neutralize the good effects of the Government work.

Saginaw River, Michigan.-The main obstruction in this river is the Carrolton Bar, where it is proposed to contine the water by means of a double row of piling, to be driven on the eastern side of the river. The other obstructions are lesser bars, which it is believed may be removed by dredging. The cost of the whole improvement is estimated at $56,000. The appropriation of June 23, 1874, will be applied to the commencement of this work. The location of certain private docks have undoubtedly had an injurious effect upon this stream, and the officer in charge of this improvement calls attention to the necessity of such legislation as will enable those in charge of river-improvements to prevent the injuries complained of.

Harbor of Refuge, Lake Huron.-During the fiscal year four cribs of the breakwater were placed in position and made secure, and all preliminary arrangements for prosecuting the work vigorously made, and all the necessary boats, derricks, dredges, and machinery furnished. The officer in charge reports the work so far done as good, with fair prospects for good progress in future.

Saint Clair Flats Ship-Canal.-The work of deepening this canal to 16 feet, 200 feet wide, is nearly completed; 194,657 cubic yards of material were dredged during the year, and it is expected that the whole amount required will be dredged for less than the estimate. No further appropriation is required. Balance in Treasury of United States July 1, 1873.. Amount expended during the fiscal year ending June 30, 1874.
