SIR: In continuation of my letter of the 28th instant, and in further answer to yours of the 27th instant, I have to give you herewith a brief summary of the work from 30th of June to 31st Dec. 1891 upon the various Rhode Island rivers and harbors in my district.

PAWTUCKET RIVER, R. I.

The channel was completed to its full width of 100 feet and depth of 12 feet at mean low water, from Dunnell's Wharf to a line opposite the Gas Co's wharf; and dredged to a width of 40 feet and depth of 12 feet from the Gas Co.'s wharf to the lower end of Grant & Co.'s wharf.

PROVIDENCE RIVER, R. I.

The projected anchorage area in the Fox Point reach and about eight-tenths of the 20-foot anchorage area of the Sassafras Point reach were completed.

GREEN JACKET SHOAL, PROVIDENCE RIVER, R. I.

The area dredged to 25 feet at mean low water was extended by about four and six-tenths acres, about two-thirds of which was to the southward and one. third to the eastward of the part already dredged.

BLOCK ISLAND HARBOR, R. I.

The north wall of the enlarged inner harbor was extended to the westward so that upon the cessation of work 195 feet of the wall west of the entrance into the harbor had been completed, an additional 65 feet built up to the level of bigh water, 145 feet up to within one foot of high water, and the foundation course laid for about 150 feet further.

Harbor OF REFUGE AT POINT JUDITH, R. I.

8,596 tons of riprap stone were placed in the breakwater near the beacon marking its southwestern angle.

PAWCATUCK RIVER, R. I.

The channel, to the full width of 100 feet and depth of 8 feet, was extended about 1,900 feet upward towards Westerly so as to reach to within about 1300 feet of the lower wharves of the city; and then continued, with a width of 40 feet, up 300 feet beyond these lower wharves; in addition which two culs 20 feet wide and about 100 feet long each were made above the 40 foot channel.

On all other Rhode Island rivers and harbors, all work was stopped prior to 30th June, 1891, further work being postponed to await further appropriations.

Very respectfully,

W. H. Bixby,

Captain of Engineers

EXTRACT FROM REPORT OF MAJOR WILLIAM R. LIVER

MORE TO CHIEF OF ENGINEERS, U. S. A., FOR 1891.

IMPROVEMENT OF PAWTUCKET RIVER, RHODE ISLAND.

The navigable part of the Pawtucket (or Seekonk) River, an arm of Provi. dence River, extends from Providence to Pawlucket, a city which in 1885 had a population of about 23,000 and extensive manufactures, depending largely on water transportation. The object of the improvement is to widen und deepen the channel leading to Pawtucket, so that vessels of 12 feet draft can reach that city at mean low water. The mean rise and fall of the tide is about 5 feet.

ORIGINAL CONDITION.

Before improvement the channel in the river had a ruling depth of about 5 feet at mean low water.

PLANS OF IMPROVEMENT.

The original project, as modified in 1883, provides for the excavation by dredging of a channel 100 feet wide and 12 fcet deep at mean low water from the deep water above Red Bridge to the ledge opposite Grant & Co.'s W barf at Pawtucket; thence the deepening by blasting of the channel through the ledge to Pawtucket Bridge to the same depth and 40 feet wide.

A plat of the river showing the lines of the proposed channel was published in the Annual Report of the Chief of Engineers for 1884, page 608.

AMOUNT EXPENDED AND RESULTS TO JUNE 30, 1890.

The total amount expended up to the close of the fiscal year ending June 30, 1890, including liabilities outstanding at that date, was $167,005. 96. The chanpel had been excavated under the original project to a width of 75 feet and a ruling depth of 7 feet at mean low water, and under the project as modified in 1883 a new channel 12 feet deep and 100 feet wide, with wide enlargements at the bends, has been carried from its mouth at the deep water just above Red Bridge a distance of about 12,740 feet, and with a width of 60 feet and of the same depth for an additional distance of about 2,000 feet. There is now a channel 100 feet wide and 12 feet deep at mean low water from the deep water above Red Bridge to Bass Rock, or to within about 13 miles of the head of pavigation, and a channel 60 feet wide and of the same depth from Bass Rock to a line about 200 feet above Dunnell's Wharf.

This completed portion of the channel is already a great benefit to the commerce of the river. A ruling depth of about 6 feet can be carried from the upper end of our present work to Pawtucket.

OPERATIONS DURING THE LAST FISCAL YEAR.

By act of September 19, 1890, Congress appropriated $30,000 for continuing the improvement, and a project for the expenditure of this sum was prepared and was approved by the Chief of Engineers. The project contemplates continuing the excavation of the channel toward Pawlucket, affording at the same time such relief as the commerce may require at the shoalest places above the main work, and the commencement of work on the ledge in the channel off Pawtucket.

Advertisements for proposals for dredging were issued November 21, 1890, and the proposals opened December 22, 1890. All were rejected, and the work was readvertised March 5, 1891. Proposals under this advertisement were opened March 25, 1891. These were also rejected.

Abstracts of proposals received under both the above advertisements will be found in the appended table.

Preparations have been made for carrying on the work by hired labor. Two Government dredges and five scows will soon be ready for the work.

WORK REQUIRED TO COMPLETE THE EXISTING PROJECT.

The work yet to be done is to excavate the channel to its full width of 100 feet from Bass Rock to a point opposite Grant & Co.'s Wharf, and thence to Pawtucket Bridge, to deepen the channel through the ledge to the same depth with a width of 40 feet,

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

It is proposed to apply the balance of the funds on band and the appropriation asked for to extending the channel toward Pawtucket by dredging, and to commencing work on the ledge.

Pawtucket is in the collection district of Providence, and that port is the nearest port of entry. The amount of revenue collected at Providence in the last fiscal year was $328,849.56. The nearest light house is Sassafras Point Light. The nearest fortifications are Fort Adams, Newport, R. I., and the fort on Dutch Island, Rbode Island.
