in the Monongahela during the passage of the rise. Under present conditions this limit no longer exists, and all coal can now be shipped for which towboats are available. During the fiscal year the lock and dam have been successfully operated without interference with navigation, except during the time that necessary repairs were being made to the lower gate. The dam has been raised and lowered two times, and has been up 164 days during the fiscal year. The cost of operating and care of the dam during the year was $12,501.25. (See Appendix F F 3.) 4. Morable dam in Ohio River below mouth of Bearer River, Pennsyl vania. Three hundred and fifty thousand dollars was appropriated for this work by acts of September 19, 1890, and July 13, 1892. All the temporary buildings were erected, and the plant required in the construction of the permanent work was purchased and placed in position. The cofferdam for the lock was completed November 11, 1892, inclosing 6.3 acres. The permanent foundations for boiler house were completed and the drift chute for lock was completed for a distance of 292 feet. The excavations for foundations of the river wall of lock were commenced October 7, 1892. The cofferdam was injured, but not materially, during the winter. Morable Dam No. 2, Ohio River. The river and harbor act of July 13, 1892, provided for the use of so much of the money appropriated for the movable dam at Beaver as might be necessary for making a survey for the location of a dam, No. 2, and for obtaining title to the land. The survey has been made. The amount expended on this work up to the close of the fiscal year ending June 30, 1892, was $6,745.24. Amount (estimated) required for completion of existing project for 550,000.00 200, 000. 00 5. Monongahela River, West Virginia and Pennsylvania.-The seven lower locks and dams on the Monongahela River belong to the Monongahela Navigation Company, and they create slack water from Pittsburg to Dunkard Creek, a distance of 88 miles. Locks and Dams Nos. 8 and 9, belonging to the United States, continue this slack water to Morgantown, a further distance of 14 miles, the distance from Pittsburg to Morgantown being 102 miles. The originally adopted project for the improvement of this river was the construction of two locks and dams to continue slack water to Morgantown, W. Va. This improve ment was completed in 1889. Lock No. 10.-By the river and harbor act of July 13, 1892, the sum of $25,000 was appropriated for beginning work on Lock and Dam No. 10. A survey was made for the purpose of determining the location of the lock, and from the data thus obtained it would appear that the most favorable site would be at some point on the first mile above Morgantown. The amount expended on this work up to the close of the fiscal year ending June 30, 1892, was $436,541.52. Amount that can be proñtably expended in fiscal year ending June 30, 1895 100,000.00 Submitted in compliance with requirements of sections 2 of river and harbor acts of 1866 and 1867 and of sundry civil act of March 3, 1893. (See Appendix F F 5.) 6. Operating and care of Locks and Dams Nos. 8 and 9, Monongahela River. These locks have been successfully operated during the fiscal year without interruption to navigation, except by the ice, which closed the river from December 26, 1892, to February 2, 1893. The lower entrances to both locks were dredged out and slight repairs made to the locks and dams. Storage sheds were constructed at both locks, and at No. 9 work was begun on two lock-keepers' dwellings. The banks below Lock No. 8 were partially protected by riprap, and at No. 9 a portion of the apron to dam was repaired; a new step was constructed and the top course of masonry at lock repaired. The cost of operating and care of these locks and dams during the year was $28,170.85. (See Appendix F F 6.) 7. Purchase of Lock and Dam No 7, Monongahela River.-The river and harbor act of August 11, 1888, made provision for the acquisition by the United States, by purchase or condemnation, of this lock and dam from the Monongahela Navigation Company. Condemnation proceedings for this purpose were instituted. The case was heard in the circuit court of the United States for the western district of Pennsylvania in November, 1890, and the value of the work was fixed at $209,000. The navigation company took an appeal to the Supreme Court of the United States, where the case was argued at the October term, 1892. The judgment of the circuit court was reversed and case remanded, with instructions to grant a new trial. July 1, 1892, balance unexpended July 1, 1893, balance unexpended..........

Purchase of Lock and Dam No. 6, Monongahela River.-An appropriation of $162,000 was made by river and harbor act of September 19, 1890, for acquisition of this structure from the Monongahela Navigation Company, after title to Lock and Dam No. 7 shall have been acquired by the United States. As the latter has not yet been obtained, no steps have been taken toward negotiating for Lock and Dam No. 6.

Cheat River, West Virginia.-The channel of this river was originally filled with rock obstructions, which interfered with the free passage of drifting logs, thereby making the transportation of timber from the head waters of this river to the markets along the Monongahela and Ohio rivers very hazardous. The river has been improved by the removal of rocks, and is now in fair condition between Rowlesburg and Green Island, a distance of 20 miles. As the appropriation for the improvement was exhausted, no further work was done during the past fiscal year. The amount expended on the project to June 30, 1892, was $12,992.50. July 1, 1892, balance unexpended July 1, 1893, balance unexpended (See Appendix F F 9.) $7.50 7.50 10. Allegheny River, Pennsylvania. The original condition of the Allegheny River as to depth, width, and navigability can not be stated in definite figures, as there is no defined plane from which to measure, both the low-water line and the elevation of the river bed being varia ble. The approved project for the improvement of the river is the removal of obstructions from the channel and the construction of low dams to close double channels, and of dikes to confine the waterway where the river is too wide. Much benefit to navigation has resulted. The late day when the appropriation of July 13, 1892, became available rendered it inexpedient to begin much new work during that season. The amount available will be expended during the coming season in building dikes and dams and removing obstructions. The following is the condition of the various works: Log chute at Corydon, Pa., 209 miles above Pittsburg.-Slight repairs were made and the work is now in good order. Dam at Cornplanter Island, 204 miles above Pittsburg.-The dam is in good condition. Dam at Hickory, 157 miles above Pittsburg.-Slight repairs are now required by reason of injuries received from the ice of last winter. The dam is otherwise in good condition. Dam at Pithole, 143 miles above Pittsburg.-This dam is in good condition. Dam at Red Bank, 64 miles above Pittsburg.-Slight repairs were made to the paving of back slope. The ice of last winter slightly damaged the paving of front slope, which should be repaired. The dam is otherwise in good condition. Nicholsons Island, 37 miles above Pittsburg.-Slight repairs were made to the paving, and a small quantity of the paving displaced by last winter's ice now requires to be replaced. The dam is otherwise in good condition. Dam at Six Mile Island, 6 miles above Pittsburg. This work is in good condition. Removal of bar at Pithole Ripple, 143 miles above Pittsburg.-The work of removing this bar was continued. During the year 2,740 cubic yards of bowlders and gravel was removed. The work is now completed, with a total removal of 3,240 cubic yards of material, and one of the worst obstructions in the Allegheny River is now out of the way. Surveys. A survey and map was made of 2 miles of river at Cowanshannock, Pa., 48 miles above Pittsburg, for the purpose of determining the location and kind of dike best adapted for the improvement of the shoal at that place. Encroachments.-The action taken against parties encroaching on the river has had the effect of restraining further encroachments to a very considerable extent. All parties reported as encroaching have been ordered to desist when it was proved that they were so doing. The amount expended on this project to the end of the last fiscal year was $178,377.85. Amount that can be profitably expended in fiscal year ending June 30,1895 25,000.00 Submitted in compliance with requirements of sections 2 of river and harbor acts of 1866 and 1867 and of sundry civil act of March 3, 1893. (See Appendix F F 10.) 11. Dam at Herr Island, Allegheny River, near Pittsburg, Pa.-The object of this dam is to begin a system of slack-water navigation and enlarge the harbor room at Pittsburg to the extent of the pool formed by the dam. The original project was for a fixed dam, but, in compliance with the request of the authorities of Pittsburg and Allegheny City, the Secretary of War has ordered that the dam at Herr Island be made a movable one. Much delay was caused by suits brought by the riparian owners, but by a change of location, so that the lock was placed out from the bank, the rights of the riparian owners were preserved, and their opposition was withdrawn. The land necessary for the lock and dam has been acquired, and all legal questions as to damages to adjoining property settled. Observations of the current and water levels at site of dam have been taken, and borings made for the purpose of determining the character of the river bed. Preparations have been also made for the construction of the cofferdam for the lock. The amount expended on this work to June 30, 1892, was $39,208.25.

(See Appendix F F 11.) 12. Ice harbor at mouth of Muskingum River, Ohio.-The object of this work was to furnish a place of refuge for Ohio River craft during ice floods. The project was the construction of a large lock through Dam No. 1, Muskingum River, to permit Ohio River vessels to pass into the pool. There has been expended thereon, up to the close of the fiscal year ending June 30, 1892, $327,930.29. The lock is now practically completed, with the exception of the machinery for operating the gates, and a small amount of masonry required to finish the lock walls. The lock can not be made available for the larger class of steamboats that usually navigate the Ohio and Muskingum rivers until the bridge of the Baltimore and Ohio Southwestern Railroad Company, just below it, has been changed. No steps have been taken by the railroad company to make the required alterations. July 1, 1892, balance unexpended........... June 30, 1893, amount expended during fiscal year.

(See Appendix F F 12.) 13. Muskingum River, Ohio.-This report is limited to work carried on under the appropriation of $102,000, by act of August 11, 1888, for the construction of a lock at Taylorsville and the reconstruction of the lock at Zanesville, Ohio. During the fiscal year a survey of the river was made, covering a distance of 4,400 feet, between the head of the canal at Zanesville and a point 500 feet above the old lock, to obtain information as to the best plan for the reconstruction of the lock at this point. The lock at Taylorsville is now practically completed with the exception of the machinery for operating the gates, but this lock can not be made available until a draw is placed in the county bridge, just below it. The commissioners of Muskingum County, to whom the bridge belongs, were ordered to change it, but thus far have not done so. The amount expended on this work up to the close of the fiscal year ending June 30, 1892, was $86,666.02. July 1, 1892, balance unexpended. June 30, 1893, amount expended during fiscal year.

Operating and care of locks and dams on Muskingum River, Ohio.As originally improved by the State of Ohio, 11 dams and 12 locks were built on the Muskingum River, furnishing continuous navigation for 91 miles from the Ohio River at Marietta to Dresden, where a connection was made with the Ohio Canal near its middle point, this canal extending from the Ohio River, at Portsmouth, to Lake Erie, at Cleveland. The work cost the State of Ohio about $1,500,000. The lock and dam above Zanesville is now in a state of ruin, but the 75 miles of slack water between the Ohio River and Zanesville has always been maintained. On this piece of river there are 10 dams, 11 locks, and 5 lateral canals, with a total length of 33 miles. The repairs to locks and dams contemplated in the project for fiscal year have been completed, and necessary incidental work done. Through navigation was suspended by reason of ice and excessive floods for a period of forty-five days. The failure of part of the old dam at Stockport (No. 6) rendered the lock useless until a coffer could be placed around the break, which, after many delays, was accomplished. The improved condition of the river was very noticeable during the low water of 1892, when a 6-foot stage was maintained in the river at a time when navigation was practically suspended on the Ohio River for want of sufficient water to per |
