During the present season it is proposed to finish both piers as shown in blue on accompanying sketch. This will give each pier a total length of 810 feet beyond the beach line. It may be that the piers will have to be extended still farther if a bar forms again across the mouth of the channel. To do the dredging still necessary and properly ballasting the piers will require an additional appropriation of $10,000, which can be profitably expended during the fiscal year ending June 30, 1873.

REPORT OF OPERATIONS AT THE HARBOR AT MUSKEGON, MICHIGAN. The superstructure over the cribs built in 1869 was finished last season, and a crib 32 feet by 32 feet was placed as a pier-head to the north pier. Last spring another crib, 32 feet by 32 feet, was placed, extending the north pier 32 feet, and the north and south piers were repaired, and the south pier re-ballasted. Both piers had been seriously damaged by vessels running into them. The cost of the work was as follows: Labor on framing and repairs of cribs and superstructure, &c. $6, 955 84 Cost of stone..

The slab-piers interior to the crib-piers are fast rotting away, and they should be replaced by pile-piers, thus utilizing the slabs now under water and in place. This work has already been recommended in previous reports, and will cost $28,000; 250 cords of stone are necessary to reballast the north pier, which will cost about $4,000. There will therefore be necessary for the fiscal year ending June 30, 1873, the sum of $18,500. Muskegon is in the collection district of Michigan, and the nearest port of entry is Grand Haven, twelve miles south. It has a small lighthouse, with lights of the sixth order.

After due advertising and opening of proposals, August 27, 1870, contracts were awarded to Messrs. Peirce & Whaling for iron, to Messrs. G..P. Adams & Bro. for stone, and to T. Stewart White for all the remaining materials, and all the work of repairing the old railroad pier. Under this contract, 200 feet of repairs were completed, and the remaining 400 feet well under way. The detailed cost of the work was as follows: 11,734 feet white-oak piles, at 15 cents per foot $1,760 10 898 50 541.58 cords of slabs, at $2 25. 12,294 pounds of drift-bolts, at $3 65 per pound. 787 pounds of screw-bolts, at 476 per pound..

A pier-head should be built at the end of the present pier, which will cost $7,000. I would again urge the building of a north pier, which will cost $200,000. Until this pier is built this harbor cannot be made one of refuge. A great deal of re-ballasting of crib-pier is necessary, and some repairs to the timber work, which will cost about $5,300. The long revetment interior to the railroad-pier, built in 1867, is in very bad repair, and I fear that a large portion of it will have to be rebuilt. It has been damaged by being used as a dock by vessels, by being run into by vessels not under control, and by being undermined by the current of the river, where it impinges against it. At present prices the repairs of this interior work (shown on accompanying tracing from A to B) would cost about $36,000. The urgency of the repairs is as great as that which required its building in 1867. On the accompanying tracing the blue lines show work in progress, and red lines new work recommended under future appropriations.

REPORT OF THE WORK OF IMPROVING THE HARBOR AT BLACK LAKE, MICHIGAN. A crib, 32 feet square in plan, was placed last autumn as a pier-head to the north pier. It was only built to the water's surface, and left to properly bed itself during the winter. There was also built 100 feet of crib-work, extending the south pier inward to prevent a breach. By a reference to the accompanying sketch, it will be seen that a further breach is threatened on the south side of the harbor, rendering imperatively necessary the work now being done, (shown in blue.) The work of first half of fiscal year was done by hired labor. After due advertising and opening of bids on August 27, 1870, contracts were awarded to the lowest bidders, Willard B. Johnson, for furnishing pine timber; John Roost for furnishing stone and slabs, and Messrs. Peirce & Whaling for furnishing iron. On May 5, 1871, after due advertising and opening of bids, contracts were awarded to Messrs. Peirce & Whaling for furnishing the iron, and to Messrs. Uriah Culbert & Co. for fur |
