wings were extended into the pool above the dam. The passage of the falls has been much improved, and navigators are well satisfied with the results thus far attained.
Jeffersonville leree.-As required by the last river and harbor act, a leveë is in process of construction at Jefferson ville, Ind. At the close of the fiscal year the levee was about one-tenth finished.
Special surreys.-During the year twenty nine special surveys were made of parts of the river requiring improvement.
The adopted method of improvement has been to remove snags and rocks, to close up duplicate channels by low dams, to hold up and guide the water by dikes where the river is too wide, and to remove bard bars and projecting points.
The construction of the Davis Island movable dam is the first step towards a more radical improvement. The amount appropriated for the improvement of the Ohio River, from the first appropriation in 1827 to July 5, 1881, is $3,770,479.25. In addition to this there has been allotted to this river a portion of twenty-three different combined appropriations for the Ohio, Mississippi, Missouri, and Arkansas rivers, which aggregate $1,947,000, but the amount thus allotted is unknown.

Amount that can be profitably expended in tiscal year ending June 30, 1897 1,000,000 Soboitted in compliance with requirements of section 2 of river and
harbor acts of 1866 and 1867. (See Appendix C C 1.) 2. Operating and care of Davis Island Lock and Movable Dam, Ohio Rirer.—The estimated amount required for operating this work during the year 1885–86 is $5,865; and during the year 1886–87 is $5,865.
(See Appendix CO 2.)
3. Operating and care of Louisrille and Portland Canal.-During the fig. cal year the canal was in operation 336 days; it was closed eight days on account of high water, and twenty one days on account of ice. During the year 4,886 vessels, representing an undertonnage of 1,217, 231 tons, passed through the canal. The total number of vessels that passed Louisville by canal and river combined was 6,397, representing an undertonnage of 1,704,941 tons. The new iron dredge for the canal has not yet been completed. During the year the middle miter sill of the new lacks was wholly rebuilt, and a house was built for the use of the attendant at the Eigbteenth Street Bridge. Iron water-pipes have been placed on the locks in order to remove deposits after a rise.
The total expenditures for the year ending June 30, 1885, were $72,369.58. The total receipts from all sources were $831.69. The estimated amount required for operating and maintaining the canal during 1885–86 is $91,840, and during the year 1886–87 is $108,810.
The question of a bigh-water lock has been decided in the negative. In lieu thereof the officer in charge recommends that the basin at the head of the dew locks be brought down as near to the locks as practi
cable, so as to expedite the service of the locks. The estimated cost is $120,000, and it is proposed to extend the work over two seasons. (See Appendix C C 3.)
4. Falls of Ohio River at Louisville, Kentucky.—Owing to sundry legal complications, work was not begun on the enlargement of the canal until October 10. A drainage ditch, 1,900 feet long, was dug through the middle of the area to be excavated, and 2,363 cubic yards of rock were removed. On June 24, 1885, bids were opened for the excavation of the area lying between the north line of the Government tract and a line drawn parallel to the present north wall of the canal, and 25 feet north of it. Bids were lower than was expected, and so large a surplus of funds was left that another contract has been let since the close of the fiscal year, carrying the excavation up to the cross-dam.

5. Monongahela River, West Virginia and Pennsylvania.-Work of Lock No. 8 was resumed in the latter part of July and continued unti December. The whole lock, except the lower wing-wall, was complete to a height of from 2 to 4 feet above Pool No. 7. Before work was be gun on the Upper Monongahela it was unnavigable, except in freshets The originally-adopted project contemplated the construction of thre locks and dams, so as to extend the existing slackwater from New Geneva to Morgantown. Of these No. 7 was to be built by the Mono gahela Navigation Company, and Nos. 8 and 9 by the United States. The amount appropriated up to July 5, 1884, toward carrying out thi project is $307,000, of which sum $303,275.06 had been expended up t June 30, 1885. The result obtained is the construction of one masonr lock and dam, and the second lock is about two-thirds finished. Th amount required is to complete Lock and Dam No. 8, all of which ca be profitably expended during the next fiscal year.

6. Operating and care of Lock and Dam No. 9, Monongahela River. The breach in the dam was thoroughly repaired and a crib-work w placed below the dam, which will probably destroy the reaction th
originally caused the damage. The total expenditures for the year were $10.091.78.
The estimate for 1885–’86 is $1,000, and the same for 1886–87.
For some reason the Stoney valve does not work as well as it did at first, and efforts will be made to ascertain and remove the cause.
(See Appendix C C 6.)
7. Allegheny River, Pennsylvania.-During the past fiscal year 70,649 cubic yards of rock, 848 snags, 3,555 cubic yaris of gravel, and one wreck were removed from the bed and banks of this river.
The officer in charge recommends that this kind of work be continued as far up-stream as Olean, and that an inclined plane be built to facilitate the passage of the Corydon Dam by rafts, and to lessen the danger to life. The method of improvement adopted on the Allegheny Rirer has been to close duplicate chaunels by low crib.dams (only two have thus far been built), and to remove the many large rocks that obstruct the bed and banks. The work of improvement was begun in 1879, and thus far there has been expended on this river the sum of $104,365.71. July 1, 1884, amount available....

8. Icc- Harbor at mouth of Muskingum River, Ohio.–Work of construction was resumed in July, and continued until the end of November. A little more than half the lock is completed, but the work is two-thirds done, as the most difficult and tedious part is finished.
The project consists in building a new and much larger lock through the State dam across the Muskingum near its mouth, with a view to securing access to the lower pool of the Muskingum for Ohio River steamboats and barges that may desire to seek shelter there during winter. There has been expended on this work to date $199,145.37, and $836.63 remain on hand.
To complete this work will require $95,163 in addition to the sum on hand, all of which can be profitably expended in the next tiscal year. July 1, 1881, amonnt available

9. Harbor of Refuge near Cincinnati.-A contract for a third dike at Four Mile Bar, Ohio River, 10 miles above Cincinnati, was made on the 28th of November. Work was begun in June, and at the end of the fiscal year the dike extended into the river 450 feet out of a total proposed length of 2,500.
The object of this work is to protect the commerce of Cincinnati dur. ing winter by catching and holding back ice floes, and secondarily to deepen the water on Four Mile Bar. Two dikes have been built, and the third and last is now under construction ; $63,470.39 have been expended on this project, and $15,000 more will be required in addition to the amount already on hand to complete it.

10. Ilarbor of Refuge at mouth of Great Kanauha River, West Virginia.A contract for erecting two ice-piers in the Great Kanawha River, a little more than a mile above its mouth, was made on February 23, 1885. At the close of the fiscal year the pier on the north side was three-fourths, and the other one-half, completed.
The object to be attained is the protection of floating craft from icefoes descending the Great Kanawha River. The cost of these piers is borne by allotments of $7,500 froin each of the appropriations for the Ohio and the Great Kanawha rivers.

Lieutenant-Colonel Merrill was also charged with survey of Muskingum Rirer, Ohio. This survey is in progress, and the results will be submitted as soon as received.
MPROVEMENT OF GREAT KANAWHA AND ELK RIVERS, WEST VIR.
GINIA, AND OF NEW RIVER, IN VIRGINIA AND WEST VIRGINIA.
Officer in charge, Lieut. Col. W. P. Craighill, Corps of Engineers.
1. Great Kanawha River, West Virginia.--This river flows through a fertile and picturesque region, filled also with mineral wealth, especially coal and salt. It was by nature divided into a number of pools, some of considerable length and depth, separated by shoals of gravel and coarse sand, which were the principal obstructions to navigation in low water, there being often on them at such seasons but a few inches of water. In some of the pools were found shallow places also obstructing navigation. There were also snags and loose rock in the channel. The navigation above Charleston was more obstructed than below. Above, it was almost suspended in summer. The coal and salt were generally sent out on rises, which enabled the boats to pass safely over the ob. structions that otherwise would stop their movements entirely. The use of the river for the movement of these valuable products was therefore unsatisfactory and intermittent. By the agency and superintendence of a board acting under the State, first of Virginia and then of West Virginia, considerable improvement in the river was from time to time effected, tolls being charged on the commerce for payment of ex. penses.
The object of the improvement, begun several years ago by the United States, was to give a constant navigable depth of at least 6 feet throughout the whole length of the Kanawha to its mouth at the Ohio River, to be accomplished by large locks and dams. Those already built hare been about 350 by 50 feet in the clear. The peculiarity of most of the dams is that they can be lowered, when the stage of water in the river will suffice, over the shoals. This gives them the name of *movable dams," and enables an open river to be had when the water is high enough.
Dams 3 and 2, both above Paint Creek, are fixed, as the declivity of the river in that section is too great to permit the advantageous use of the movable system. Dam 1 will also be fixed.
Up to June 30, 1884, the amount expended was $1,411,739.15. At that date Lock and Dam 3, 21 miles above Charleston Ferry, had been completed, as also Locks and Dams 4 and 5, respectively 15 and 9 miles above the same point. Lock 6, 4 miles below Charleston, was also
