it which was included between the 15-foot curves, takes up about 18 acres.

There were channels on either side of the shoal, between it and the harbor lines, having, the one on the north side, a width of 300 feet and a depth of 20 feet, and the one on the south side, a width varying from 50 to 100 feet and a depth of about 15 feet at mean low water. The water on the summit of the shoal was 1 foot deep.

PLANS OF IMPROVEMENT.

The general project is the removal of the entire shoal to a depth of 25 feet at mean low water, limiting the work by lines drawn 200 feet from the harbor lines.

A plat of Green Jacket Shoal was published in the Annual Report of the Chief of Eogineers for 1885, vol. I, page 599.

AMOUNT EXPENDED AND RESULTS TO JUNE 30, 1890. The amount expended, including outstanding liabilities, to June 30, 1890, was $54,250. The result was the excavation to a depth of 25 feet at mean low water of an area of about 138 acres, extending along the northern and western sides of the shoal, making an important addition lo the anchorage facilities of the harbor. On a portion of this area the depth of water before the completion of the contract of Nov 18, 1886, was from 3 to 4 feet.

OPERATIONS DURING THE LAST FISCAL YEAR.

At the beginning of the last fiscal year no work was in progress. By act of September 19, 1890, Congress appropriated $25,000 for continuing this work, and a project for the expenditure of this sum was prepared and was approved by the Chief of Engineers. The project provides for the continuation of the dredging to the east and south of the area already excavated.

Advertisements for proposals for dredging were issued November 21, 1890, and proposals opened December 22, 1890. These were all rejected.

The work was readvertised March 5, 1891. Proposals under this advertise. ment were opened March 25, 1891. An abstract of proposals received under both the above advertisements and the terms of the contract will be found in the tables appended to report on improvement of Providence River, Rhode Island, page 714.

WORK REQUIRED TO COMPLETE THE EXISTING PROJECT. The work required to complete the existing project is the excavation of the remainder of the shoal to a depth of 25 feet.

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

It is proposed to apply the balance on hand and the funds asked for to continuing the removal of the shoal according to the general project.

Green Jacket Shoal is in the collection district of Providence, which is a port of entry. The amount of revenue collected at Providence during the last fiscal year was $269,858. The nearest light-houses are the six light-houses in Provi. dence River. The nearest fortifications are Fort Adams, R. I., and the fort op Dutch Island, Rhode Island.

IMPROVEMENT OF GREENWICH BAY, RHODE ISLAND.

Greenwich Bay an arm of Narragansett Bay, cated in the towns of Warwick and East Greenwich, R. I. It has a length from northwest to southeast of about 3} miles and an average width of 13 miles.

The channel leading to the town of East Greenwich was deep enough for the present demands of commerce, but so crooked as to render navigation difficult.

This is a new work, and no appropriation had been made for it until, by act of September 19, 1890, Congress appropriated $2,000 for widening the channel.

PLAN OF IMPROVEMENT.

The improvement contemplated was the straightening and widening of the channel by the removal of sand bars and shoals.

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 funds was prepared and was approved by the Chief of Engineers. The project provided for dredging to a depth of 10 feet at mean low water on the western edge of the bar extending out from Long Point, carrying the work to the eastward as far as the funds would permit. Advertisements for proposals for dredging were issued November 21, 1890, and proposals opened December 22, 1890. All were rejected. An abstract of the proposals received will be found in the appended table.

Work was commenced April 10, 1891, with the dredge Texas, tug Sargon, and scows, all belonging to the United States. The Sargon was required for other work and was transferred April 17, and replaced by a hired tug.

Nineteen thousand five hundred and ninety-two cubic yards were excavated during the year, and the result was the completion of the project, by cutting off the bar extending out from Long Point, about 210 feet. The channel was widened for a distance of about 500 feet.

Mr. C. 0. Abell was the local superintendent.
The project being completed, no work is anticipated for the coming year.

Greenwich Bay is in the collection district of Providence, which is a port of entry. The amount of revenue collected at Providence during the last fiscal year was $328,849.56. The nearest fortification is the fort at Dutch Island, Rhode Island. The nearest light-house is Warwick Light.

IMPROVEMENT OF COVE AND WATER-WAY NEAR COASTER HAR

BOR ISLAND, RHODE ISLAND.

This cove is situated in the northwestern part of the city of Newport, R. I., near the southeastern extremity of Couster Harbor Island, which is occupied by the U. S. Navy as a training station. A causeway connecting Coaster Harbor Island with Rhode Island forms the northern boundary of the cove and sepa. rates it from the water way above. This causeway having but one small opening has checked the flow of water around the island and caused deposits, so filling the water way as to cause it to give forth unhealthy and disagreeable odors.

This is a new work, and no appropriation had been made for it until, by act of September 19, 1890, Congress appropriated $5,500 for improving the cove and water way.

PLANS OF IMPROVEMENT.

The projected improvement is to dredge the cove to the necessary depth, and to increase the flow of water by larger openings in the causeway, so that garbage and waste thrown into the water will be carried away by the current.

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 contemplates deepening by 3 feet as much of the cove as the funds permit and making two additional open. ings in the causeway, spanned by two bridges.

Advertisements for proposals for dredging were issued November 21, 1890, and proposals opened December 22, 1890. All were rejected. An abstract of proposals received will be found in the appended table.

Work was commenced February 6, 1891, with dredge Texas, tug General Warren, and scows belonging to the United States, and was suspended April 1, 1891, the General Warren having been replaced in the meantime by the tug Sargon, also Government property; 31,281 cubic yards were excavated, completing the dredging contemplated by the project.

The bridges are framed and ready to put in position in a short time.

Work REQUIRED TO COMPLETE THE Existing PROJECT.

To complete the existing project it is only necessary to cut the causeway and erect the bridges.

Coaster Harbor Island is in the collection district of Newport, which is a port of entry. The amount of revenue collected at Newport in the last fiscal year was $1,878.91. The nearest light-house is Gull Rock Light. The nearest forti. fication is Fort Adams, Newport, R. I.
