a narrow sand spit at the mouth of the harbor, was washed and abraded by the waves and currents at high water, and the material was carried into and shoaled the channel inside.

The present approved project of 1880, as modified in 1887, provides for a channel 250 feet wide and 10 feet deep at mean low water from Barney Point down to the entrance to the harbor. Above Barney Point the width of the channel is to be 350 feet, with the same depth 10 feet-as below that point. The plan includes also the raising and strengthening of Long Beach, of which a large portion was submerged at low water, to carry it above the storm waves and currents and to hold it there, in order to prevent the filling of the improved channel above, by material abraded from the beach; the whole at a total cost, as estimated in 1887, of $56,236.

Forty-nine thousand dollars was appropriated, and $44,746.07 was paid out on this work up to June 30, 1891; this expenditure resulting in the completion of the channel in the upper part of the harbor in front of the wharves to its full width, the deepening to 10 feet of the channel for about one-half its width from Barney Point to Wareham, and a portion of Reach No. 9, formerly obstructed by the shoal known as the Middle Ground, and the raising of Long Beacli above high-water storm tides, so that the wash of sand into the improved channel inside the beach has been considerably stopped.

The ruling depth of the approaches to Wareham has been increased from 7 to 9 feet, and the channel greatly widened in all the reaches. Vessels of larger draft can be carried to Wareham than formerly. The increase in width of channel is a great help to all vessels in beating in and out of the harbor.

During the last fiscal year work under contract was commenced on June 8, and was in progress at the end of the year, by which the channel was widened at its narrowest points above Barney Point.

The balance available will be applied to continuing the work of dredging and to the building up of Long Beach if necessary. July 1, 1891, balance unexpended....

6. New Bedford Harbor, Massachusets.--New Bedford Harbor is an estuary of Buzzards Bay, and is the port of the cities of New Bedford and Fair Haven.

Before improvement the channel had a depth of about 124 feet at mean low water. Old projects of 1874 and 1877 provided for a channel 300 feet wide and 15 feet deep at mean low water from the deep water just above Palmer Island to the wharves at New Bedfou. Tuis work was completed in 1877 at a cost of $20,000.

The present approved project of 1987 provided for a channel 200 feet wide and 18 feet deep at mean low Wuter, at a total cost, as estimated in 1887, of $35,000.

Twenty thousand dollars was appropriated and $12,968.33 was paid out on this work, up to June 30, 1891; this expenditure resulting in the excavation to half width of a channel 100 feet wide and 18 feet deep from the 11-foot bank to the vicinity of the wharves of New Bedford.

During the last fiscal year, work was commenced on November 1 and continued to December 1, by which about 2,000 feet length of channel was widened and deepened.

The work required to complete the existing project is the excavation of the remaining half of the channel 200 feet wide and 18 feet deep, extending from the “11-foot bank” to the vicinity of the wharves at New Bedford, and the removal of a few shoal spots between the “11foot bank” and Butlers Flats, the southern end of the projected channel.

The balance available will be applied to the continuation of this project. July 1, 1891, balance unexpended

7. Westport Harbor, Massachusetts.-Westport Harbor is an estuary on the coast of Massachusetts, lying between Narragansett Bay, Rhode Island, and Buzzards Bay, Massachusetts. The site of the work is on Horse Neck Point (the north side of the entrance to the harbor.)

Before the commencement of the improvement the site of the present work was a point of sand forming the northern and eastern boundary of the entrance to the harbor, and subject to erosion by the sea and tides.

In 1886 $1,000 was appropriated for special protection of Horse Neck Point. This work was completed in 1887.

The present approved project of 1888 provides for the construction of jetties at the end of Horse Neck Point to stop the wearing of this point and also for a small amount of dredging in the harbor; the whole at a total cost, as estimated in 1888, of $2,000.

One thousand dollars was appropriated and $22.96 was paid out on this work up to June 30, 1891; this expenditure being for preparations for field work.

At the beginning of the last fiscal year no work was in progress. Work was commenced September 10 and continued to October 9, by which the old work at Horse Neck Point was rebuilt and strengthened.

Preparations have been made for carrying on the work by hired labor.

The work required to complete the existing project is the extension of the present jetty and the dredging on the Lions Tongue Shoal.

The balance on hand will be applied to the completion of the existing project.

8. Taunton River, Massachusetts.—This river rises in Norfolk County, Mass., and empties into Narragansett Bay at Fall River. The object of the improvement is to deepen and widen the channel leading to the city of Taunton, at the head of navigation, so that vessels of 11 feet draft can reach the city at high water.

In its original condition the channel was narrow and obstructed by bowlders, and from Berkley Bridge to Taunton the depth was not, in places, more than 5 feet at mean high water. A vessel of 30 tons burden was as large as could go up to Taunton.

From 1870 to 1879 $63,000 was appropriated to secure 9 feet depth at high water. This work was completed in 1879.

The present approved project of 1880, as modified in 1888, provides for a channel 60 feet wide and 11 feet deep from Weir Bridge to the shipyard, a channel 80 feet wide (100 feet at the bends) and 11 feet deep from the shipyard down to and through the Needles and Briggs Shoal; thence to Berkley Bridge a channel of the same width and 12 feet deep, and from Berkley Bridge to the deep water at Dighton the channel was to be 100 feet wide and 12 feet deep. The depths are estimated from high water. The ledge which crossed the bottom of the river at Peter Point and the numerous bowlders which lay on the bottom and sides of the channel from Taunton to Dighton were to be removed, at a total cost, as estimated in 1888, of $108,000.

One hundred and one thousand dollars was appropriated, and $96,654.31 was paid out on this work up to June 30,1891; this expenditure giving results as follows:

With the exception that but 40 feet of the 60 feet of width could be dredged between the bridge at Weir and the shipyard, on account of interfering with private property, and that on account of the hardness and depth of material at the sides the 80-foot channel was not in all cases dredged to its full width, the channel down to Berkley Bridge had been completed. The channel as proposed between Berkley Bridge and Dighton had been completed, with the exception of removing a small amount of ledge rock uncovered in dredging below Peter Point, and had been cleared of bowlders from Taunton down to Berkley Bridge. The work of removal of the ledge at Peter Point had been completed. The material blasted in the channel had been dredged and deposited in the form of a half-tide dam running from Reuben Island to the west shore of the river, with the view of accelerating the current in the dredged channel off and above Dighton and preventing deposits in this part of the channel. Vessels of 11 feet draft can now reach Taunton, at the head of navigation.

The work of dredging with plant belonging to the Government and a hired tug was in progress at the beginning of the fiscal year. The dredging was commenced at the second shoal above Berkley Bridge and continued up stream. The second reach and a portion of the third were completed.

There remain, to complete the existing project, widening and deepening at a few points above the bridge and the removal of the small amount of ledge rock above referred to.

The balance available is to be applied to continuing the improvement. July 1, 1891, balance unexpended..

9. Pawtucket River, Rhode Island.—This river, otherwise called Seekonk River, is the upper portion of Providence River, and extends from Pawtucket to Providence. Before improvement the channel in the river had a ruling depth of about 5 feet at mean low water.

Between 1867 and 1832, $52,000 was appropriated to dredge the channel to 7 feet depth. This work was finished in 1876.

The present approved project of 1883 provides for the excavation by dredging of a channel 100 feet wide and 12 feet deep at mean low water from the deep water above Red Bridge to the ledge opposite Grant & Company's wharf at Pawtucket; thence the deepening by blasting of a channel through the ledge to Pawtucket Bridge, of the same depth and 40 feet wide, at a total cost, as estimated in 1883, of $382,500.

One hundred and forty-five thousand dollars was appropriated and $120,452.02 was paid out on this work up to June 30, 1891, this expenditure resulting in the securing of a new channel 12 feet deep and 100 feet wide, with wide enlargements at the bends, from the deep water above Red Bridge to within 14 miles of the head of navigation, and 60 feet wide and of the same depth to within three-fourths of a mile of the same point.

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.

At the beginning of the fiscal year no work was in progress. Work of dredging was commenced on August 8, 1891, and continued to October 31, by which 70,000 yards of material was removed from the narrowest parts of the channel. Work was done by hired labor using two Government dredges and five scows.

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 & Company's wharf, and to deepen the channel through the ledge to the same depth with a width of 40 feet.

It is proposed to extend the channel towards Pawtucket by dredg. ing and to commence work on the ledge.

10. Providence River and Narragansett Bay, Rhode Island. The object of this improvement is to furnish a wide and deep channel for foreign and coastwise commerce from the ocean to Providence.

Before the improvement of the river was commenced in 1853 many shoals obstructed navigation, and at one point in the channel, a place called " The Crook," the available low-water depth was but' 4feet. Between 1852 and 1873, $56,500 was appropriated to secure first 9 and then 12 feet depth of channel. This work was finished in 1873,

The present approved project of 1878, modified in 1882, provides for a channel 25 feet deep and 300 feet wide, suitable for large ocean ves. sels, extending from Fox Point, in the city of Providence, to the deep water of Narragansett Bay, and for an anchorage basin between Fox and Field Points, 300 feet wide, at a depth of 25 feet; 600 feet wide, at a depth of 20 feet; 725 feet wide, at a depth of 18 feet; 910 feet wide, at a depth of 12 feet; 1,060 feet wide, at a depth of 6 feet, at a total cost, as estimated in 1882, of $675,000.

Five hundred and sixty thousand dollars was appropriated and $533,790.83 was paid out on this work up to June 30, 1891; this expenditure resulting in the completion of the 25-foot channel 300 feet wide, and more than half of the anchorage basins.

At the beginning of the fiscal year work under contract was in progress and was continued until August 10, by which over 87,000 cubic yards of material was removed from the anchorage basins.

There is required for the completion of the existing project the excavation of the remainder of the anchorage basin between the head of Sassafras Point Reach and Field Point.

The balance available will be applied to the continuation of the work according to the project. Jnly 1, 1891, balance unexpended

11. Removal of Green Jacket Shoal, Providence River, Rhode Island.This shoal is in that part of Providence River which constitutes the harbor of Providence. It lies off the wharves, on the south front of the city, and occupies a part of the harbor that is required for anchorage purposes, covering an area of about 18 acres between the 15-foot curves, and about 30 acres in all.

The present approved project of 1885 provides for 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, at a total cost, as estimated in 1885, of $112,346.

Seventy-nine thousand two hundred and fifty dollars was appropri.
