This barbor is at the main entrance to Narragansett Bay. These waters during the summer and winter constitute a harbor of refuge for our European and coastwise commerce quite equal in every respect to that of New York Harbor, and are even more accessible. The objects of the improvement are to widen and deepen the southern (the main) entrance to the harbor, and to enlarge its capacity for vessels seeking refuge in storms, by increasing the area and depth of the anchorage within it. The mean rise and fall of the tide is about 31 feet.

ORIGINAL CONDITION,

Before improvement the capacity of the inner harbor was limited by shoals, and it was not adequate to the number and size of vessels seeking it for refuge. The southern (the main) entrance was obstructed by a bar wbich stretched out from Goat Island, and the general business wharves of the city could not be reached at low tide by vessels drawing more than 8 feet.

PLANS OF IMPROVEMENT.

The original project and its modifications under which we are now working are substantially as follows:

Deepening the southern entrance to 15 feet at mean low water and widening it by dredging Goat Island Spit northward to a line drawn from the dolphin which marks the spit to clear the permanent dock at Fort Adams by 100 feet; the excavation of a channel 750 feet wide and 15 feet deep at mean low water around and to the eastward of this dolphin; excavating to 13 feet at mean low water the area included between the 13-foot curve on the west, a line drawn from the southwest corner of Perry Mill Wharf to Lime Rock on the south, the harbor line on the east, and a line drawn parallel to and 50 feet from the city wharf on the north; excavating to 10 feet at mean low water the area northwest of a line drawn from Lime Rock through the spindle, which is in the southeast part of the harbor; the excavation of a channel 10 feet deep at mean low water along and outside the harbor line south to a point opposite the gas company's wharf, and the construction of jetties on the western shore of Goat Island to arrest the drift of littoral sand and gravel into the southern entrance.

A plat of Newport Harbor, showing the plans of the work, was published in the Annual Report ol the Chief of Engineers for 1885, Vol. I, Page 604.

AMOUNT EXPENDED AND RESULTS TO JUNE 30, 1890.

The amount expended up to the close of the fiscal year ending June 30, 1890, including outstanding liabilities at that date, was $120,202 03, with the follow. ing results:

The area to be dredged to 13 feet within the barbor had been completed. The channel along and outside the harbor line south to a point opposite the gas company's wharf, and the 15-foot channel 750 feet wide around and to the eastward of the dolphin op Goat Island Spit, had been completed, with the exception of a strip along the western edge and to the north of the dolphin. The berth for vessels at the quartermaster's wharf at Fort Adams had been deepened to !0 feet at mean low water, and the littoral sand from the outside of Goat Island had been stopped for the present from washing into the channel at the southern entrance of the harbor by the construction of a jetty on the west side of the island. The southern entrance is completed for vessels of 15 feet draft, and of the total area to be dredged within the harbor (about 90 acres) about two-thirds had been completed.

OPERATIONS DURING THE LAST Fiscal YEAR.

At the beginning of the last fiscal year no work was in progress. By act of September 19, 1891, Congress appropriated $12,500 for continuing the improvement.

A project for the expenditure of this sum was prepared and was approved by the Chief of Engineers. This project provides for the completion of the 15-foot channel by dredging the remainder of the strip along the western edge north of the dolphin; for dredging in the 10-foot anchorage area, and, if necessary, for the construction of an additional jetty on the west end of Goat Island. Advertisements for proposals for dredging were issued November 21, 1890, and proposals opened December 22, 1890. An abstract of the proposals received and the terms of the contract will be found in the appended tables.

Work under this contract commenced February 7, 1891, and was finished April 18, 1891. Thirty-four thousand eight hundred and forty.six cubic yards were excavated in the areas specified by the project, and the result was the dredging of the strip along the western dge of the 15-foot channel north of the dolphin and the excavation of about 6 acres of the 10-foot anchorage area.

Mr. J. R. Easton was inspector of the work.

WORK REQUIRED TO COMPLETE THE EXISTING PROJECT.

The work required to complete the existing project is the excavation of the 10-foot anchorage area within the harbor and the building of additional jetties outside of Goat Island whenever they may be required to arrest the drift of littoral sand and gravel into the harbor entrance.

OPERATIONS CONTEMPLATED DURING THE FISCAL YEAR ENDING JUNE 30, 1892.

It is proposed to apply the funds asked for to the completion of the existing project.

Newport is in the collection district of Newport, and is a port of entry. The amount of revenue collected at Newport in the last fiscal year was $1,878.91. The nearest light houses are Lime Rock and Newport (Goat Island) lights. The nearest fortification is Fort Adams, Newport, R. I.

HARBOR OF REFUGE AT POINT JUDITH, RHODE ISLAND. Point Judith is the southeastern extremity of South Kingstown, R. I., and marks the southwestern entrance to Narragansett Bay. Its shores are covered with bowlders, and a number of wrecks are scattered along the beach on each side of the point. A long ledge, known as Squid Ledge, extends for nearly a mile in a south by easterly direction about 11 miles west of the point.

This is a new work, and no appropriation had been made for it until, by act of September 19, 1890, Congress appropriated $75,000 for a National Harbor of Refuge at Point Judith.

PLAN OF IMPROVEMENT.

It is proposed to construct breakwaters along the course of Squid Ledge, mentioned above, and between the southern extremity of the ledge and Point Judith,

A plat of the locality was published in House Ex. Doc. No. 66, Fifty-first Congress, first session.

OPERATIONS DURING THE LAST FISCAL YEAR.

Immediately after the passage of the act making the appropriation for this work, a project for the expenditure of the available funds was prepared and was approved by the Chief of Engineers. The project provides for commencing the work on the outer end of Squid Ledge, and extending the one arm to the north, and the other to the east, with a view to securing a sheltered area for the vessels engaged on the work.

Advertisements for proposals for furnishing and placing riprap granite were issued December 5, 1890, and proposals opened January 5, 1891. All were rejected. An abstract of bids received will be found in the appended tables.

The work was commenced February 13, 1891, by establishing a beacon at the angle of the breakwater, and a portion of the two arms above referred to was built. Work was in progress at the close of the fiscal year.

The capacity of the quarry at Mason Island has been increased to about 400 tons per day, and a Government tug and barge have been prepared for this work. A powerful steamer and five barges have been chartered for the summer and fall.

In this exposed situation it is proposed to take advantage of favorable weather during these seasons for putting stone in the work. About 3,000 tons have been already placed in the arms above referred to, in addition to the stone required for the beacon, which has been maintained 10 mark the position of the submerged stone since the commencement of the work. Mr. Win. Babcock Poland is the local superintendent.
