nishing all other materials and all the work. Work during the present season was commenced May 31, and has been confined to driving piles. It was found necessary to employ a dredge for about six days to remove the debris of stone and sand which had fallen into the channel on the south side, in order to properly drive the piles. The following is a detailed statement of cost of materials and work for the fiscal year: 1,398 linear feet white-oak piles, at 13 cents per foot... 128 128 8,375 pounds of drift-bolts, at 33 cents per pound $188 73 559 00 1, 492 99 6 72 6 10 4,314 02 814 62 314 06 1,053 pounds of drift-bolts, at 3.65 cents per pound.

The revetment to the channel-way should be finished as soon as practicable. This work is shown in red on the accompanying tracing. To do this 850 feet of close piling in addition to what is now under course of construction will be required, which will cost $12,500. Unless this work is done great damage may result.

The work is now under construction and it is hoped that it will be finished by November 1, 1871. The blue lines on accompanying tracing show the rows of protecting piles. The recommendation made in my last report for a north pier and necessary revetment at mouth of river is renewed. This work will cost $59,300 98, and this amount can be profitably expended during the fiscal year ending June 30, 1873. Saugatuck is in the district of Michigan.
