3. Sacramento and Feather rivers, California.-Before improvement navigation in these rivers was dangerous and difficult on account of numerous snags, shallow bars, and rapids. In 1874 a project was adopted having for its object the temporary improvement of the low-water channels by removal of snags, building of wing dams to concentrate currents, and the scraping of bars. Work under this project has been carried on during every working season, and together with the closure of several breaks in the banks, which threatened to injure navigation, cost up to June 30, 1892, $481,680.99. The results of the work were to secure and maintain on the Sacramento River a good navigable channel from McIntosh Landing down to Butte City for boats drawing 23 feet; from that point to Sacramento 4 feet of water, and below Sacramento a lowwater channel with a least depth of 5 feet has been secured. On the Feather River there is channel from Marysville, the head of navigation, to the mouth for boats and barges drawing 2 feet of water.

At the beginning of the fiscal year the snag boat was at work in the upper Sacramento River, and continued so until November 5, when the channel had been put in good order as far up as Tehama, 29 miles above McIntosh Landing. This opened up 29 miles of river that had not been used by steamboats for over ten years, and gave a channel from Tehama to McIntosh for boats drawing 2 feet of water. The other channel depths in the river below were maintained as in former years. The cost of the snagging was $13,121.26, and was of the greatest benefit to commerce, in fact without it navigation in the upper Sacramento River could not be maintained.

During this last fiscal year the project was increased to include the closure of Jacob Slough, a large crevasse just above the city of Sacramento; the maintenance of navigation on the Feather River by means of wing dams to remove shoals, and the treatment of the Yuba River, near and above Marysville. Under this project surveys have been made to ascertain the exact conditions existing. Bids were received and opened at the end of the fiscal year for the closure of Jacob Slough, and a project has been made and approved for cutting a new mouth for the Yuba River. No actual work has yet been done, so no results have been attained.

The total amount spent on the improvement of these rivers during the last fiscal year has been $22,856.49, and the result has been of great benefit to the large and increasing commerce of the country adjacent to the rivers. The improvements done on these rivers have resulted in greatly reducing the rates of freight and insurance.

The report of a Board of Engineers appointed to examine these rivers is printed in House Ex. Doc. No. 246, Fifty-first Congress, second session, and in Annual Report, Chief of Engineers, 1891, p. 2990.

4. Petaluma Creek, California.-In its original condition this creek was very crooked and at low tide its bed, in places, was bare. In 1880, a project was adopted for its improvement by which it was designed to obtain by dredging a channel 50 feet wide by 3 feet deep at low water. For this purpose $35,892.95 was expended up to June 30, 1892, in dredging in the channel and making cut-offs. The channel proposed was obtained and maintained. Much of this work consisted of redredging, as owing to the adjacent country being in a high state of cultivation the dredged channel constantly refills.

The river and harbor act of July 13, 1892, appropriated $10,000 for this work, and to determine where the greatest need for dredging existed a survey of the creek was made and submitted to the Department, together with a project for the expenditure of the funds. It was proposed to carry on work with the United States dredge usually occupied in the San Joaquin River, but at this time idle on account of high water. Accordingly the dredge was put in working order and taken to Petaluma Creek, where it commenced work on May 2, 1893, at Haystack Landing, 3 miles below the town of Petaluma, working upstream. By June 30, a channel 5,107 feet long by 50 feet wide, 3 to 4 feet deep at low water, had been dug, and 37,171 cubic yards of material excavated and placed on the banks 50 to 100 feet back from the cut, at a cost of $4,184.03, or 11.2 cents per cubic yard. The work is still in

progress.

The result of the work has been of great benefit to the navigation interests and no serious detentions have been reported of late years. As stated above the channel is continually refilling, and to keep it open dredging must be done every two years at an estimated cost of $4,000. July 1, 1892, balance unexpended

5. Humboldt Harbor and Bay, California.-In its original condition the channels inside this bay were shallow, and great difficulty was experienced in getting shipping to the wharves in Eureka, Arcata, and Hookton. To improve these conditions a project was adopted in 1881 to dredge inside the harbor and obtain a channel to Eureka of 13 feet depth at low water, with a width of 200 feet; also, to obtain a channel to Arcata and Hookton 10 feet deep and 100 feet wide. Work under

this project was commenced in 1881, and the project completed in 1884 at a cost of $96,061.25. These channels have since refilled to some ex-tent, but vessels are not much inconvenienced thereby. Vessels now rarely go to Hookton, but go to Fields Landing, situate in the bay just south of the entrance. It may be necessary in the near future, in the interests of commerce, to improve in width or depth either the Bucksport or the Old West Channel.

In 1882 another project was made to obtain and maintain deeper water across the bar at the entrance. It was proposed to control the tidal flow and secure its scouring effects by means of a training-wall some 6,000 feet long, running out from the south spit. After work was commenced, great scour took place on the north spit, and the project was enlarged to embrace the construction of a jetty on the north spit; also, to build both jetties up to high water and extend them to the 18foot curve. On account of continued erosion on the north spit the project was again modified, in accordance with the views of a board of engineers, submitted December 16, 1892, the change consisted of relocating the north jetty so as to utilize the shore protection built on the north spit and make it part of the proposed north jetty, and its construction to a sufficient length to arrest erosion before completion of the south jetty; after this both jetties are to be carried simultaneously to the 18-foot curve.

Jetty work was begun in 1889 and carried on until October, 1890, when the contractor failed. At this time the south jetty was built out 2,967.6 feet, 900 feet of which was up to high-water level. In May, 1891, work began again under another contract and continued until December, 1891. Protection work, similar to that used in jetty construction, was built on the north spit and carried out 1,480.5 feet. The south jetty was carried out some additional 600 feet, making it 3,699.2 feet long. This completed the contract.

The cost of jetty work up to this time was $298,325.67. This made the total amount expended on the improvement of this harbor up to June 30, 1892, $394,387.23.

During the calendar year 1892 no work was done, as the funds available were not sufficient to warrant entering into a new contract.

The river and harbor act of July 13, 1892, placed this work under what is known as the continuous-contract system and appropriated for it $150,000. On December 16, 1892, a contract was made to continue operations. In addition to the amounts already available $522,000 was appropriated by the sundry civil act of March 3, 1893. Work was begun in April, 1893, on the north spit, where some damage had been done to the trestle by drift logs, and about 1,000 feet of the shore track washed away. This was repaired and work commenced on the extension of the jetty. Up to June 30, 1893, 14,224 tons of rock and 4,779 cubic yards of brush were delivered, and 832 feet of trestle built. No work has been done on the south jetty this season. During April and May a few of the outer bents of piling were destroyed, but little or no damage was done to the jetty proper.

On the south spit the sands are accumulating rapidly, it being estimated that 2,000,000 cubic yards have already been arrested by the jetty built there.

Little benefit can as yet be expected from the work done, but the 18foot channel mentioned in last year's report has remained reasonably permanent, and vessels have not been detained, as formerly, by want of water on the bar.

IMPROVEMENT OF CERTAIN RIVERS AND HARBORS IN OREGON, WASHINGTON, AND IDAHO.

This district was in the charge of Capt. Thomas W. Symons, Corps of Engineers, with Lieuts. Graham D. Fitch and Francis R. Shunk, Corps of Engineers, under his immediate orders; Division Engineer, Col. G. H. Mendell, Corps of Engineers.

1. Coquille River, Oregon (general improvement). Before improvement the entrance to the Coquille River was considered very dangerous. It was by a long, tortuous, and narrow channel, skirting the south headland, and studded with rocks from beyond the bar to a distance of one-half mile inside. The depth at low water was only about 3 feet and the channel was constantly shifting. At long intervals the channel would break through the north spit and run directly out to sea just south of Rackliffe Rock, but never remained long in this position. At such times the entrance was comparatively safe and the channel was at its best. The mean rise of tide was 4.1 feet.

The first plan of improvement was to construct two parallel hightide stone jetties, 800 feet apart, running out to sea a sufficient distance to open and maintain over the bar a channel with a least depth of 8 feet at low water; the north jetty starting from Rackliffe Rock and the south jetty from a point inside the entrance. Under date of May 8, 1891, the project was changed to provide for an entrance width. of 600 instead of 800 feet. The estimated cost of this improvement was $164,200.

The law of August 11, 1888, authorized the expenditure of $5,000 in snagging between Coquille City and Myrtle Point; the law of Septem
