Of the improvements which have been or are to be made by the United States, under approved projects, about 2,200 feet of the dredged channel and the whole of the basin in the West Branch and nearly a mile of the dredged and projected channel, together with the basin in the East Branch, are within the general shore line and inside the inner harbor. In the West Branch the basin and upper portion of the channel are adjacent to the wharves, which are all within a half mile of the head of the harbor. In the East Branch nearly all the docks are within a quarter of a mile of the head of the harbor, and extend nearly or quite out to the channel.

Coscob Harbor, Connecticut. - Some small side channels have been dredged at various times from the main channel, just above the railroad bridge, to private docks on the west shore, the largest channel being about 800 feet long, 35 feet wide, and 4 or 5 feet deep.

Of the improvements which have been or are to be made by the United States, under approved projects, that portion of the work above the railroad bridge is within the general shore line and inside the inner harbor. The only docks adjacent to the channel are Lockwood's dock, about 1,900 feet above the railroad bridge, and the docks at Mianus, at the extreme upper end of the proposed channel.

Greenwich Harbor, Connecticut. In the east branch, known as Indian Harbor, some improvements have been made by individuals. The details of the work are not known.

Of the improvements by the United States which are to be or have been made, under approved projects, in Greenwich Harbor proper, the upper 200 feet of the 9-foot channel and the whole of the 6-foot channel are within the general shore line and inside the inner harbor. These channels extend along the west shore, and are adjacent to the docks for practically their whole length.

Respectfully submitted.

No improvements of the navigable waters in charge of this office have been or are being undertaken by municipalities, private corporations, or individuals in conjunction with the Government.

Improvements have been made by such parties alone, as follows: Dredging has been done to connect deep-water channels with private slips, and channels in front of private docks have been redredged from time to time at Port Chester, Echo Bay, and Peekskill harbors, East Chester and Wappinger creeks, Bronx, Harlem, and Hudson rivers, and Flushing Bay.

Dikes constructed by the State are being utilized as part of the improvement of the Hudson River between Troy and Coxsackie.

The following improvements are within the corporate limits of the city of New York:

East Chester Creek, Bronx River, Flushing Bay, East River and Hell Gate, Harlem River, Newtown Creek, and Canarsie Bay.

At the following localities the works of improvement have been carried in places up to the pierhead line, and docks and works have been built out to the channel lines, thus making the channels "adjacent to wharves:"

Port Chester Harbor, Echo Bay Harbor, East Chester Creek, Bronx River, Port Jefferson Harbor, Huntington Harbor, Flushing Bay, East River and Hell Gate, Harlem River, Newtown Creek, Canarsie Bay, Patchogue River, Hudson River, Saugerties Harbor, Rondout Harbor, Wappinger Creek, and Peekskill Harbor, New York.

(6) REPORT OF MAJ. W. L. MARSHALL, CORPS OF ENGINEERS, SECOND NEW YORK, N. Y., DISTRICT.

UNITED STATES ENGINEER OFFICE,

New York City, August 1, 1902. GENERAL: In compliance with Department letter of July 25, 1902, I have the honor to submit the inclosed report, containing information called for by section 13 of the river and harbor act of 1902, for all navigable waters in the district in my charge.

Very respectfully, your obedient servant,

Brig. Gen. G. L. GILLESPIE,

W. L. MARSHALL, Major, Corps of Engineers.

Chief of Engineers, U. S. A.

This district includes the several channels of approach to New York City from the sea by the southern entrance (through the Narrows), Buttermilk Channel, Gowanus Creek channel, Gowanus Channel, and the Red Hook and Bay Ridge channels.

No improvements of these navigable waters have been or are being undertaken by municipalities, private corporations, or individuals in conjunction with the Government.

The following improvements have been made by such parties alone: (a) In Buttermilk Channel the Atlantic Dock Company has dredged along its docks and in some instances has extended the work a short distance beyond the harbor lines to meet the improved channel.

(6) In Atlantic Basin, Erie Basin, and other smaller basins, a large amount of dredging has been done by parties controlling the wharves in these basins. These basins are navigable waters of the United States in the sense that harbor lines are established within them; for purposes of improvement they have always been regarded as private waters, and the United States has expended no money in them.

(c) Prior to 1896, when it was specifically provided for in the river and harbor act, the improvement of the Gowanus Canal above Percival street was made by the municipality (then the city of Brooklyn). The amount expended by the city is not known; the amount expended by the United States was $5,000. Above Hamilton Avenue Bridge, beyond the established harbor lines, improvements of Gowanus Canal have been altogether made by the city.

(d) In Bay Ridge Channel a small amount of dredging outside the harbor lines has been done by private corporations to connect deep water in the channel with private slips.

The following works of river and harbor improvement in this district lie within the corporate limits of the city of New York, as such limits now exist:

Works in progress: (a) Buttermilk Channel; (b) Gowanus Creek channel; (c) Bay Ridge and Red Hook channels; (d) removal of obstruction in North River, off Pier 1.

Completed works: (e) Gowanus Canal; (f) removal of Baxters Ledge; (g) Dredging at Government piers, Forts Hamilton and Wadsworth; (4) Coney Island channel.

The following works of improvement have been carried up to the pierhead line in places; piers have been built out to the harbor line, thus making the channels "adjacent to wharves:" (a) Buttermilk Channel; (6) Gowanus Creek channel; (c) Gowanus Canal; (d) Bay Ridge and Red Hook channels; (e) channels to Government piers.

(7) REPORT OF LIEUT. COL. C. W. RAYMOND, CORPS OF ENGINEERS, PHILADELPHIA, PA., DISTRICT.

ENGINEER OFFICE, UNITED STATES ARMY,

Philadelphia, Pa., September 26, 1902.

GENERAL: In compliance with instructions contained in Department letter, dated July 25, 1902, to Capt. Spencer Cosby, Corps of Engineers, relative to the improvement of navigable waters of the United States by municipalities, etc., I have the honor to submit the following special report covering all the navigable waters of the districts in my charge, and giving the information required by the provision of section 13 of the river and harbor act approved June 13, 1902, covering this matter. The river and harbor works in my charge are as follows:

PHILADELPHIA DISTRICT.

Delaware River, Pennsylvania and New Jersey.

National harbor of refuge, Delaware Bay.

Delaware breakwater, Delaware.

Construction of iron pier in Delaware Bay, near Lewes, Del.

Passaic River, New Jersey.

Raritan River, New Jersey.

NEW YORK DISTRICT,

The channel between Staten Island and the New Jersey shore (including Lemon Creek).

Arthur Kill, or Staten Island Sound, from Kill van Kull to Raritan Bay, New York and New Jersey.

Elizabeth River, New Jersey.

South River, New Jersey.

Raritan Bay, New Jersey.

Matawan Creek, New Jersey.

Keyport Harbor, New Jersey.

Shoal Harbor and Compton Creek, New Jersey.

Shrewsbury River, New Jersey.

Manasquan River, New Jersey.

Woodbridge Creek, New Jersey.

In the Philadelphia district the improvement of the Delaware River, from Trenton to its mouth, has been aided by the State of Pennsylvania and the city of Philadelphia. The amount paid by the State was $200,000, while the city of Philadelphia paid $1,143,652.86; the total amount contributed by both being $1,343,652.86. Below Trenton the channel has been dredged by a transportation company.

The Delaware River lies partly within the corporate limits of the cities of Trenton, N. J., Camden, N. J., and Philadelphia, Pa., and includes Philadelphia Harbor, the improvement of which was completed in 1898. The channel dredged through the harbor was adjacent to the wharves on both sides of the river. The national harbor of refuge, as well as the harbor behind Delaware breakwater, are parts of Delaware Bay, Delaware, and lie between the State lines of New Jersey and Delaware.

The thirteen river and harbor works in the New York district are tidal waterways, inlets, and streams forming water routes from New York Harbor, Raritan Bay, and Newark Bay to interior cities or to landings back of or inside of the general coast lines.

The Shrewsbury River is the only work in the district where improvement has been carried on by private corporations in conjunction with the Government. In this river dredging is frequently done by two steamboat lines running eight boats. This work is necessary for the removal of shoals which form continually at certain points in the river channels, as the Government work alone has not been sufficient to maintain the project depth of 6 feet at mean low water, which is required for the commerce of the river.

In the Passaic River at Newark the city removes shoals deposited at the mouths of sewers.

Dredging has been done by private corporations and individuals, and also for the purpose of gaining access to the channels dredged by the United States at the following localities, viz: Passaic River, channel between Staten Island and New Jersey, Arthur Kill, or Staten Island Sound, Raritan Bay, Raritan River, South River, Elizabeth River, and Shrewsbury River. At these localities the channels may be regarded as "adjacent to wharves."

At the following places the channels dredged by the Government lead directly to and are contiguous to wharves: Shrewsbury River, Shoal Harbor and Compton Creek, Lemon Creek, Raritan River, South River, Elizabeth River, Matawan Creek, Keyport Harbor, and Woodbridge Creek.

The following works are within or partly within corporate city limits: Passaic River, in the cities of Newark and Passaic; Elizabeth River, in the city of Elizabeth; Raritan River, the improvement of which ends at the city of New Brunswick.

At Manasquan River no private work has been done; the work is not adjacent to wharves and does not lie within corporate city limits. It lies within the Atlantic coast line.

At the following localities, viz: Rahway and Hackensack rivers and

Cheesequakes Creek, and not now on the list of improvements, private dredging has been done to gain access to wharves and channels.

In 1866 a channel 6 feet deep was dredged to wharves at Keyport Harbor by private parties.

In carrying out the improvement of South River, New Jersey, the United States utilized the "Little Washington Canal," 4,500 feet long, 0 feet wide, and about 6 feet deep at low tide, which was cut through from the Raritan River at Sayreville to intercept the South River at a point 24 miles by the river channel above its mouth. This canal was cut about the year 1830 by the New Jersey Transportation Company, and was merged into the improvement by the United States in 1871. Very respectfully, your obedient servant,

REPORT OF COL. JARED A. SMITH, CORPS OF ENGINEERS, WILMING

ΤΟΝ, DEL., DISTRICT.

ENGINEER OFFICE, UNITED STATES ARMY,

WILMINGTON, DEL., August 26, 1902.

GENERAL: In compliance with Department letter of July 25, 1902, requesting the information respecting this district called for by section 13 of the river and harbor act approved June 13, 1902, I have the honor to submit the following:

* * *

*

*

Schuylkill River, Pennsylvania. - Improvements undertaken by the city of Philadelphia consist of dredging a channel in the Schuylkill River, which flows within the corporate city limits, 350 feet wide and 26 feet deep between the back channel and Penrose Ferry Bridge; 250 feet wide and 26 feet deep from Penrose Ferry Bridge to Fiftyeighth street, and 200 feet wide and 22 feet deep from Fifty-eighth street northward. The present contract, which is nearly completed and includes also certain work in the Delaware River, finishes that portion of the Schuylkill River below Penrose Ferry Bridge. The contract amounts to $238,000. An additional appropriation of $400,000 has been made by the city for continuing these improvements.

Appoquinimink River, Delaware. In 1879 the citizens of Odessa, Del., with $1,700 raised by subscription, made three cut-off's by dredging for the improvement of this river.

Mispillion River, Delaware. In 1899 and 1901 the citizens of Milford, Del., and vicinity, at their expense, dredged the channel at the mouth of the Mispillion River.

Murderkill River, Delaware. - Up to about twenty years ago the improvement of the Murderkill River was in charge of an improvement and navigation company chartered by the State of Delaware, and it expended about $10,000 in rectifying the many bends of the river by cutting straight canals and in dredging a cut across the flats at the mouth.

Cambridge Harbor, Maryland. This harbor was improved by the citizens of Cambridge up to 1871, at which time $7,500 had been expended by them for that purpose.
