built to 834 feet length with full height; then came a gap of 160 feet, and then 1,300 feet length raised to half-tide level, completing about half the needed work.

Operations during the past fiscal year.-Value of United States plant, $7,000. Including $599.05 of outstanding liabilities the expenses of the year were $2,649.07.

During the year a project had been submitted and approved for work under the new appropriation, bids to be asked for the delivery of stone, modified later to allow of work by hired labor and the use of the Government plant. A minor survey had been completed to serve as a basis for the coming season's work.

A light has been maintained on the west jetty during the year except during July, 1892, when from the exhaustion of the appropriation it had to be left unattended.

This work was in the local charge of Mr. J. H. Rostock as assistant engineer.

Work required to complete the existing project.-The work required to complete the existing project is the extension of the east jetty, the raising of the west jetty in some places, and the excavation by dredging of so much of the channel as may not be excavated by tidal scour. Operations contemplated for the fiscal year ending June 30, 1894.-The work has been much delayed heretofore by the scour around the end of the jetty, making it necessary to build it in 15 feet of water instead of in 5. According to the present plan it is proposed to build up a considerable length of the jetty to the half-tide level before completing it to the full cross section. The channel appears to be moving continually to the eastward and deepening slightly from year to year.

It is proposed to apply the balance on hand and the funds asked for to the further construction of the east jetty and raising low places in the west jetty, together with a little dredging, if necessary.

Nantucket is in the Nantucket collection district and is a port of entry. There was no revenue collected in the last calendar year. The value of the harbor is mainly as a harbor of refuge. The nearest light-houses are Nantucket Cliff and Brant Point lights. The nearest fortification is the fort at Clark Point, New Bedford, Mass.

(Amount (estimated) required for completion of existing project... Amount that can be profitably expended in fiscal year ending June 30, 1895 Submitted in compliance with requirements of sections 2 of river and harbor acts of 1866 and 1867 and of sundry civil act of March 3, 1893.

Abstract of proposals opened January 9, 1893, at Newport, R. I., by Capt. W. H. Bixby, Corps of Engineers, for stone to be delivered in the jetties at Nantucket Harbor, R. I.

The commerce arriving and leaving Nantucket Harbor by water during the calendar year ending December 31, 1892, is estimated as follows (based mainly upon reports received from Mr. Joseph W. Clapp, collector of customs, Nantucket, Mass.):

Gain over last year, about 3,000 tons, or $90,000. Transportation lines established during the year, sailing packet line (Wm. T. Swain owner) between Nantucket and New Bedford, Mass.

The passage of vessels through this waterway is estimated as follows (each entrance and departure together being counted as one passage):

C 3.

IMPROVEMENT OF MARTHAS VINEYARD INNER HARBOR AT EDGARTOWN, MASS.

The inner harbor at Edgartown lies in the northern part of the waterway or strait that separates Chappaquiddick Island from the east end of Marthas Vineyard. It extends southward about 1 miles from Chappaquiddick Point, opposite Edgartown, and averages about one-fifth of a mile in width.

This harbor is so completely landlocked as to form a safe harbor of refuge for small vessels, but the contracted width of the entrance and the resulting velocity of the tidal currents make it difficult to pass through. (For map of this harbor see House Ex. Doc. No. 59, of Fiftyfirst Congress, first session.)

Original condition.-At the adoption of the present project the middle-ground shoal carried only about 6 feet depth of water and was a very troublesome obstruction.

Plan of improvement.-The present approved project, that of 1889, provides for the removal to 10 feet depth at low water of a "middle ground" shoal in the central part of the inner harbor; all at a total cost estimated in 1889 of $4,500.

A description of the works may be found at p. 588, Annual Report of the Chief of Engineers for 1890, and a plan of the same in House Ex. Doc. No. 59, of the Fifty-first Congress, first session.

Appropriations.-Under the present project appropriations have been made as follows: 1890, $2,000; 1892, $2,500. Total up to June 30, 1893, $4,500.

Amount expended and results to June 30, 1892.-The total amount expended on the present project (including $11.39 outstanding liabilities) up to June 30, 1892, was $1,945.40, by which about half of the shoal had been dredged to full depth.

Operations during the past fiscal year.-Value of United States plant, $200. Including $126.54 of outstanding liabilities, the expenses of the year were $2,448.75.

During the year a project has been submitted and approved for work under the new appropriations, allowing all work to be done by hired labor and the use of the Government plant. A minor survey has been made to serve as a basis for the coming season's work. The dredging (commenced April 21, stopped May 9) has been completed as far as funds would allow; and 9,494 cubic yards of hard sand have been removed from 2,035 feet length and 33 feet width of cutting, and to a depth of at least 10.5 feet at low water, leaving about one-quarter of the original shoal still unremoved.

This work was in the local charge of Mr. J. H. Rostock as assistant engineer.

Work required to complete the existing project.-The work required to complete the existing project is the excavation of the remaining quarter of the Middle Ground to a depth of 10 feet at mean low water.

The original estimates of Maj. Livermore (p. 588, Annual Report of 1890) placed the cost of work at $4,500, to be expended in one year. The funds, however, were divided between two small appropriations of $2,000 in 1890 and $2,500 in 1892. Had the whole $4,500 been available in 1890 the work would undoubtedly have been completed in 1891 and within the original estimates. Nearly half of each appropriation has had to be spent in putting the dredging plant in repair, moving it
