the wharves so far as the steamboat wharf, except over four small ledges uncovered by the dredging near the Halibut Company's Wharf. Nothing had been done on the breakwater.

On September 16, 1892, a contract was entered into for the completion of the proposed dredging. No operations have been in progress during the fiscal year, and at the date of this report the condition of the improvement is the same as on June 30, 1892.

8. Manchester Harbor, Massachusetts.-Manchester Harbor is situated about 51⁄2 miles northeast from the entrance of Salem Harbor, Massachusetts.

The channel was 100 feet wide and 6 feet deep at mean low water up to Proctor's Point; it then shoaled rapidly to a depth of 14 feet at the "Narrows," 1,400 feet from Proctor's Point, and for a further distance of 2,500 feet to the town wharves no low-water channel existed.

The project for its improvement proposed to dredge a channel from Proctor's Point to the town wharves, 60 feet wide and 4 feet deep at mean low water, at an estimated cost of $14,300. The total appropriations to date have been $14,300. The expenditures to June 30, 1892, were $7,122.09. On June 30, 1892, the improved channel was 35 feet wide 4 feet deep at mean low water from Proctor's Point to the railroad bridge, a distance of 2,900 feet.

On September 17, 1892, a contract was entered into for the completion of the project. No operations were in progress under this contract during the fiscal year, and at the date of this report the condition of the improvement is the same as on June 30, 1892.

9. Salem Harbor, Massachusetts.--Salem Harbor is 12 miles northward of Boston, Mass. It contains a well-sheltered, entirely unobstructed anchorage of about 110 acres, more than 18 feet deep at mean low water.

The principal city wharves are located on South River, a small stream entering the harbor. This river was 3,000 feet long, from 150 to 300 feet wide, and not navigable at low tide.

The original project for the improvement of this harbor was submitted December 16, 1872. It proposed to dredge a channel of approach to the mouth of South River, 1,730 feet long, 300 feet wide, and 8 feet deep at mean low water. This project was essentially completed in 1873-75.

The present project was submitted December 2, 1889. It proposed to clear out the channel as originally dredged, and to extend it to the head of navigation, gradually reducing its width from 150 feet at the mouth of the river to 100 feet near the inner end of Derby Wharf, and above this to excavate a channel 50 feet wide. To the inner end of Derby Wharf the improved channel to be 8 feet deep at mean low water, and above this point 6 feet deep. The total length of the improved channel to be 5,100 feet approximately.

The total appropriations to date have been $53,000. The expenditures to June 30, 1892, were $37,782.62. At that date the entrance channel dredged in 1873-275 had been cleared out to essentially its original dimensions, and the improved channel was 50 feet wide, 8 feet deep to near the inner end of Derby Wharf, and thence, to the head of navigation, 6 feet deep, at mean low water.

On September 17, 1892, a contract was entered into to complete the proposed improvement. No operations were in progress under this contract during the fiscal year.

10. Lynn Harbor, Massachusetts.-Lynn Harbor is 9 miles northeast from Boston.

The original channels were narrow and crooked, and had but 6 feet depth at mean low water.

The project for improvement was adopted in 1884. It proposed a channel 200 feet wide, 10 feet deep at mean low water, through the outer and inner bars. It is supposed that the inner channel will require occasional dredging, and a training wall was proposed, if required, to aid in keeping the outer channel open.

On September 24, 1888, it was proposed to extend the inner channel 400 feet within the harbor line, and to excavate at its inuer end an anchorage basin 500 by 300 feet in area, 10 feet deep at mean low water, at a cost of $25,000.

The estimated cost of the original project was $157,000.
The total appropriations to date have been $101,000.

The amount expended to June 30, 1892, was $85,098.13. At that date the outer channel and basin were completed as proposed, and the inner channel was 150 feet wide.

On January 5, 1893, a contract was entered into to dredge a channel 150 feet wide, 8 feet deep at mean low water, at the entrance of the western channel, and to widen the inner channel of the main harbor to 200 feet, so far as the balance available would permit. Operations were commenced in June, 1893, in the western channel under this contract, and 4,583 cubic yards was dredged during the fiscal year.

11. Winthrop Harbor, Massachusetts.-Winthrop Harbor is situated in the northeastern part of Boston Harbor. It contains 350 acres, approximately, all of which is essentially dry at low tide. The mean range of tides is 9.4 feet.

The original project for its improvement proposed to dredge a straight channel 3,900 feet long, 50 feet wide, 6 feet deep at mean low water, from the "Back” channel of Boston Harbor to Rice's Wharf. The total appropriations to date have been $9,000. The expenditures to June 30, 1892, were $5,497.80.

At that date

the improved channel was 3 feet deep at mean low water, 3,900 feet long, and 35 feet wide.

On December 20, 1892, a contract was entered into for the completion of the proposed improvement. Operations under this contract

were commenced in March and completed in May, 1893.

At the date of this report the improved channel is 3,900 feet long, 50

feet wide, 6 feet deep at mean low water.

12. Mystic and Malden rivers, Massachusetts.-These two rivers. empty into the inner harbor of Boston, Mass.

Malden River is tributary to the Mystic River, their junction being about three miles above the mouth of the latter.

Originally no low-water channel existed in either river.

A project for the improvement of Mystic River was submitted May 9, 1891. It proposed to widen and deepen the natural channel to the head of navigation in Medford, a distance of about 4 miles, so that it should be 100 feet wide, 6 feet deep at mean low water, to the first turn above Denning's wharf; thence 4 feet deep at mean low water, the width gradually contracting to 50 feet at the upper end; estimated to cost $25,000.

The original project for the improvement of Malden River was submitted December 1, 1880, and was modified in 1882. The modified project proposed to make the natural channel 100 feet wide, 12 feet deep at mean high water, to the first bridge, and thence 75 feet wide to

the second bridge, the estimated cost of completing this work being $37,000.

The mean range of tides is 9.8 feet.

Ten thousand dollars was appropriated for the improvement of Malden River in 1882, and expended, 1883-'84, in accordance with the project, making a channel 50 feet wide, 12 feet deep at mean high water, to the first bridge.

The act of July 13, 1892, appropriated $10,000 for the improvement of Mystic and Malden rivers. Five thousand dollars of this amount is retained in the Treasury for the improvement of Malden River (when additional funds are available), and the balance will be expended in improving Mystic River as proposed.

Bids were opened September 8, 1892, for the proposed work in Mystic River, but the lowest was rejected as excessive.

No other operations were in progress during the fiscal year.

At the date of this report the original condition of Mystic River is unchanged; and the improved channel of Malden River is at least 50 feet wide, 12 feet deep at mean high water, to the first bridge in Malden, a distance of 14 miles.

13. Boston Harbor, Massachusetts.-The object of this improvement is, first, to preserve the harbor by protecting the islands and headlands; and, second, to improve it by widening, straightening, and deepening the channels.

The projects adopted for this purpose since 1866 have been mainly in accordance with the recommendations of the United States commissioners whose labors terminated during that year.

The works of preservation consist of sea-walls, aprons, jetties, etc., which protect the shores of the islands and headlands, prevent additional wash into the channels, control tidal scour, and preserve the full height of anchorage shelter for vessels in the roadsteads. Such have been built or repaired at Point Allerton, and the islands of Great Brewster, Lovells, Gallops, Long Deer, Rainsford, Georges, and Castle. The works of improvement have been by dredging and blasting, by which means many dangerous rocks and shoals have been removed and the main ship channel enlarged from 100 feet wide and 18 feet deep at mean low water, so that it is now at least 625 feet wide and 23 feet deep at mean low water.

The following tributary channels have also been improved:

a. Charles River.-The natural channel of this river has been widened, straightened, and deepened, so that from its mouth to Western Avenue Bridge, a distance of 43 miles, the channel has a width of 200 feet, and a depth of 7 feet at mean low water; thence to Arsenal Street Bridge, 24 miles, the channel has a least width of 80 feet and a least depth of 6 feet.

b. Fort Point Channel.-This important branch of the main ship channel had a least depth of 12 feet at its entrance, and the channel was narrow and crooked. It has been widened to 175 feet, and deep

ened to 23 feet at mean low water from its mouth to Congress Street Bridge, a distance of 1,900 feet.

c. Hingham Harbor.-See separate report.

d. Nantasket Beach Channel. This channel was originally about 50 feet wide, 8 feet deep at mean low water. It is now 150 feet wide, 10 feet deep at mean low water.

e. Channel between Nix's Mate and Long Island.-This channel had originally 4 feet depth at mean low water. A cut has been made through the bar 300 feet wide, 15 feet deep at mean low water.

f. Broad Sound.-An obstruction called Barrel Rock was removed in 1869.

The total expenditures to June 30, 1892, were $2,216,351.59.

During the fiscal year the main ship channel was widened at the upper middle from 800 feet to 850 feet, and at Jeffreys Point from 275 feet wide to 350 feet wide.

A revised project was adopted August 11, 1892, which proposes to make the main ship channel 27 feet deep and 1,000 feet wide through

out.

A contract was entered into under date of October 17, 1892, for dredging the main ship channel, and 5,666 cubic yards was removed under this contract during the fiscal year.

A contract was entered into under date of September 30, 1892, for dredging in channel off Jeffreys Point, and 20,697 cubic yards was dredged during the fiscal year.

A contract was entered into under date of September 22, 1892, for dredging in Nantasket Beach Channel, and 21,594 cubic yards was dredged during the fiscal year.

All these contracts were in force at the close of the fiscal year. Repairs were made to the sea wall at Great Brewster Island, and the riprap at the west end of the Long Island sea wall was extended.

At the date of this report the several works of preservation are in fair order; the main ship channel is 23 feet deep at mean low water, 1,100 feet wide west of the upper middle, 850 feet wide at the upper middle, 1,000 feet wide at the lower middle, and at least 625 feet wide at the Narrows. The subsidiary channels are in the same condition as at the date of the last report.
