Chicago Harbor, Illinois.-During the year the breakwater was extended 800 feet, (the cribs in this length reaching only to the watersurface,) and the superstructure was completed over the rest of the work. At the close of the fiscal year the breakwater was 3,050 feet long, including the return at north end of 300 feet. The superstructure over the last 800 feet has not been laid. It is expected that 1,100 feet will be added to the breakwater the present fiscal year, leaving 150 feet of crib-work and 2,050 feet of superstructure to complete the breakwater according to the original plan. It is proposed during the fiscal year ending June 30, 1875, to finish the breakwater and to extend the north pier 400 feet. The construction of the south pier will be deferred until it is determined whether wharves are to be built on the west side of the new harbor.

On the 1st of July, 1873, there was a channel 11 feet in depth and 75 feet in width. During this season the north pier will be extended 350 feet, and the south pier 300 feet. A dredge is employed in widening and deepening the channel. In view of the rapid growth of the city of Chicago, this harbor will soon be of great utility. Amount available July 1, 1872..

Improvement of the Fox and Wisconsin Rivers.-The improvement of the navigation of the Wisconsin River, in accordance with the plan explained in former reports, is being carried out successfully. The results are given in detail in the accompanying reports. The transfer of canals, locks, dams, &c., in the Fox River to the Government by the Green Bay and Mississippi Canal Company was effected in September, 1872, in pursuance of the act of Congress approved June 10, 1872. By the act of Congress dated March 3, 1873, the sum of $300,000 was appropriated for the improvement of these rivers, $100,000 being allotted to the Wisconsin and $200,000 to the Fox River. The operations on the Fox for the present season will consist in putting the existing work in repair; deepening the canals and riverchannels, and replacing worn-out and unsuitable work, for the details respecting which reference is made to the accompanying report. In general the plan adopted for this improvement is: First, the repair and replacing of the existing works on the Fox River; secondly, the construction of additional locks and dams to complete the system of slack-water navigation on the Upper Fox; thirdly, the deepening and widening of the channels in the various levels; fourthly, the completion of the improvement of the Wisconsin River by contracting and fixing the low-water channel; and, finally, the replacing of all the existing locks and dams by permanent work. The total estimated cost of this work is about $2,600,000, or not to exceed $3,000,000. In order to carry on this work advantageously, a large outlay is required for proper machinery, dredges, boats, &c.
