portion of the river, was printed, in House Ex. Doc. No. 94, Fifty-first Congress, first session, and in the Annual Report of the Chief of Engi neers for 1890, page 1665. a. Between Rome, Georgia, and the East Tennessee, Virginia and Geor. gia Railroad Bridge.-The expenditure up to June 30, 1890, of $519,671.31 had resulted in securing a fairly navigable channel from Rome, Ga., to Greensport, Ala., by blasting out the rock shoals, and by the construction of wing dams to scour out the sand bars. Three masonry locks, each 40 feet wide by 210 feet between miter sills, at distances, respectively, of 0.68, 3.86, and 5.24 miles below Greensport, with their accessory dams and dikes, were sufficiently completed to be opened to navigation in the spring of 1890, and the Rome and Gadsden steamers now extend their trips to landings below Lock No. 3. During the year ending June 30, 1891, the sum of $63,713.61 has been expended. Lock keepers' houses have been built at Locks Nos. 1, 2, 3, and 4. At Lock No. 1 guide cribs have been built at the head and foot of the lock; two levees have been built, and such portions of the land side of the lock as were subject to wash in high water have been paved. At Lock No. 2 a guide crib has been built at the foot of the lock, and such portions of the bank on the land side of the lock as were subject to wash at high water have been paved. At Lock No. 3 a guide pier has been built at the head of the lock, and a similar pier at the foot of the lock partly built; the bank on the land side of the lock has been leveed and paved, where subject to wash, and the dam has been strengthened. Some channel work has been done below the lock. At Lock No. 4 material has been procured for building the permanent dam and the cofferdam; a new quarry has been opened, and part of the stone needed for the abutment and for filling the dam has been quarried; a tram-road, leading from the lock to this quarry, a distance of 1.9 miles, has been built and equipped with small locomotive and cars; and a hoisting and conveying apparatus has been procured for conveying the stone from the end of the tramway to the dam and the abutment on the opposite side of the river by means of a wire cable stretched across the river over the site of the dam. Other necessary plant, in the way of hoisting engines, steam pumps, etc., has been bought. It is expected with the money now available to be able to complete, during the present season, the dam, abutment, and levee, and the upper part of the cofferdam. b. Between Wetumpka and the East Tennessee, Virginia and Georgia Railroad Bridge.-The act of September 19, 1890, appropriated $150,000 for the improvement of this portion of the river, with the proviso that such improvement "be made in harmony with the existing approved project for the improvement of the Coosa River between Rome and said bridge; locks to be 40 feet wide and 210 feet between miter sills.". During the year ending June 30, 1891, $8,681.31 has been expended. In order to determine the best location for Lock No. 31 at Wetumpka, and for Locks Nos. 30 and 29, at approximate distances, respectively, of 2 miles and 4.65 miles above Wetumpka, it was necessary to make a careful and detailed survey of this portion of the river, and to take careful velocity and discharge measurements at all stages of the river from low to high water. For this purpose a surveying party has been employed at Wetumpka since October, 1890. The proposed location of Lock No. 31 is now under consideration. As soon as this is definitely decided upon the available balance will be Between Wetumpka and the East Tennessee, Virginia and Georgia Railroad Bridge. $150,000.00 8, 681.34 July 1, 1891, balance unexpended 141,318.66 July 1, 1891, balance available .... 140, 495. 21 Amount (estimated) required for completion of existing project..... 4,943,074.00 500,000.00 Submitted in compliance with requirements of sections 2 of river and (See Appendix P 11.) 12. Operating and care of canals and other works of navigation on Coosa River, Georgia and Alabama.-The expenses of operating Locks Nos. 1, 2, and 3 during the past fiscal year have been paid in the manner indicated by section 4, act of July 5, 1981. The amount expended during the fiscal year ending June 30, 1891, was $2,530.67. (See Appendix P 12.) 13. Cahaba River, Alabama.-The report of the examination of this river from its mouth to Centreville, Ala., in 1874, states that On thirteen of the shoals there is only 1 foot of water, and on two as little as eighttenths of a foot. Besides this there are innumerable snags, the accumulation of years, and also a great quantity of leaning trees, which must be removed owing to the narrowness of the stream even at a stage several feet above low water. The river is spanned by three bridges. * The railroad bridges are only a few inches above high water, while the road bridge is sometimes submerged. * * The road bridge mentioned was carried away by the flood of 1881. Under acts of Congress approved June 23, 1874, and June 17, 1880, examinations and partial surveys were made in 1874 and in 1880, and a plan of improvement was adopted which provides for obtaining for the lower Cahaba River, from its mouth to the town of Centreville, a distance of 88 miles, a navigable channel with a width in open river of 100 feet, and in soft rock and bar cuts of 60 feet, having a depth at low water of 3 feet, by the removal of snags, etc., from the channel and overhanging trees from the banks, by cutting through the soft rock and gravel bars, and by contracting and regulating the channel. The expenditure up to June 30, 1886, of $28,989.79 had resulted in the partial improvement of the river from its mouth to Centreville, adapting it to high-water navigation; but, on account of the obstructing railroad bridges, steamboats were unable to make any use of the improved river. Since that time no work has been done, because of a proviso in the river and harbor act of August 5, 1886, that No part of said sum [$7,500 appropriated for this work] shall be expended until the officer in charge shall have reported that the railroad and other bridges across said river have been provided with good and sufficient draw openings. These bridges continue to obstruct the navigation of the river, not having been provided with draw openings. The act of September 19, 1890, provided that The existing provision restricting the expenditure of the balance now available for the improvement of said river are hereby repealed, and said balance shall be expended in continuing the improvement thereof. Under this appropriation an examination of the river was made in November, 1890; the construction of a light-draft log boat, to be used in working on the river, was authorized, and was begun in April. This boat will be finished in July, 1891, and will be put to work clearing the river of logs and snags until the available funds are exhausted. During the fiscal year ending June 30, 1891, $3,506.56 were expended in defraying the expenses of the examination and in the construction of the log boat and the purchase of the necessary machinery for it.

(See Appendix P 13.) EXAMINATIONS FOR IMPROVEMENT, TO COMPLY WITH REQUIREMENTS OF RIVER AND HARBOR ACT APPROVED SEPTEMBER 19, 1890. The required preliminary examination of Chattahoochee River, Georgia and Alabama, between West Point and Franklin, was made by the local engineer in charge, Captain Price, and report thereon submitted through Col. C. B. Comstock, Corps of Engineers, Division Engineer, Southwest Division. It is the opinion of Captain Price, based upon the facts and reasons given, that this locality is worthy of improvement; but Colonel Comstock, in view of the cost of improvement and the present and prospective wants of commerce, does not consider the locality worthy of improvement at this time. The views of Colonel Comstock being concurred in by me, no further survey was ordered. The report was transmitted to Congress and printed as House Ex. Doc. No. 134, Fiftyfirst Congress, second session. (See also Appendix P 14.) The required preliminary examination of Alabama River, Alabama, to ascertain cost of securing a 6-foot channel at low water from mouth to Wetumpka, was made by the local engineer in charge, Captain Price, and report thereon submitted though Col. C. B. Comstock, Corps of Engineers, Division Engineer, Southwest Division. It is the opinion of Captain Price, and of the Division Engineer, based upon the facts and reasons given, that this river is worthy of improvement as proposed. The report of the preliminary examination containing sufficient information to indicate to Congress the probable cost of the work required, no further survey appears to be necessary at this time. The cost of securing a 6-foot channel as proposed is estimated at $386,251, and the annual cost of maintaining it at $10,000. The report was transmitted to Congress and printed as House Ex. Doc. No. 140, Fifty-first Congress, second session. (See also Appendix P 15.) IMPROVEMENT OF CERTAIN RIVERS IN ALABAMA AND MISSISSIPPI, OF BOGUE CHITTO, LOUISIANA, AND OF HARBORS AT MOBILE, ALABAMA, AND BILOXI, MISSISSIPPI. Officer in charge, Maj. A. N. Damrell, Corps of Engineers; Division Eugineer, Col. C. B. Comstock, Corps of Engineers. 1. Mobile Harbor, Alabama.-The present project for the improvement of this harbor was adopted in August, 1888, the object being to afford a channel of entrance from the Gulf of Mexico to the city of Mobile of 280 feet width on top of cut, with a central depth of 23 feet at mean low water by dredging, at an estimated cost of $1,980,000. Length of continuous cut, 29 miles. Act of September 19, 1890, extended the work up Mobile River to the mouth of Chickasabogue Creek and increased the estimated cost to $2,043,800. The channel had originally a minimum depth of 5 feet through Choctaw Pass and 8 feet on Dog River Bar. This was deepened by dredging under appro priations from 1826 to 1852 of $228,830.68 to 10 feet through both. In 1860 the channel in Choctaw Pass had shoaled to 7 feet. From 1870 to 1878 the channel was deepened by dredging to 13 feet under appropriations amounting to $401,000. Length of cut 8 miles. From 1881 to 1888 the channel was deepened by dredging to 17 feet, under appropriations amounting to $740,000, but this project was not completed when the last project was adopted. The length of cut was 25.91 miles. The entire length of channel under present project is 31.85 miles and the entire length of continuous cut is 29.98 miles. Since the adoption of the last, or present, project a channel has been dredged to a depth of 19 feet and width of 80 feet from where there was that depth in Mobile River to where the same depth was found in the lower part of the bay, a continuous cut of over 26 miles; about onehalf was done in the fiscal year 1888-'89, and the remainder during the fiscal year 1889-'90. The lower portion has shoaled so that the least depth is now 14.7 feet. The average central depth is, however, about 19.4 feet for the whole length of the channel. The amount available is to be applied to continuing the improvement in accordance with the approved project, and it is believed will secure a minimum depth of at least 20 feet.
