Beginning again at the point in the easterly side of Eastern avenue, above described, the pier-head line follows the easterly side of said avenue northerly a distance of 80 feet; thence turns easterly and runs parallel to the line on the southerly side of Bass Creek till it intersects with the westerly side of Marginal street; thence turning easterly and northerly by the arc of a circle of 530 feet radius and a tangent thereto to a point in the south side of Willoughby street extended easterly 530 feet from the southwest corner of Willoughby and Marginal streets; thence to a point in the north side of Dana street extended easterly 800 feet from the east side of Marginal street; thence to a point in the north side of Bancroft street extended easterly 900 feet from the east side of Marginal street; thence to a point in the south side of Louis street extended easterly 1,100 feet from the east side of Marginal street; thence to a point 580 feet southeasterly from the east side of the abutment of the Eastern Railroad Bridge over Chelsea Creek, measuring in a line perpendicular thereto at a point 50 feet southwest from the northeast corner of said abutment; thence by the arc of a circle of 200 feet radius turning northerly and westerly through an angle of about 141°; thence in a tangent to said circle to the point 50 feet southwest of the abutment above referred to; thence to the northeast corner of said abutment; thence along the face of the abutment to the northwest corner; thence in a straight line, making an angle of 65 degrees with the western face of said abutment, to the dam of Slade's tide-mill.

Bulkhead Line. Beginning at the intersection of the south side of Marginal street with the west side of Chelsea Street Bridge, the line follows the southerly side of said Marginal street and its prolongation northeasterly to the easterly side of the Grand Junction Railroad Bridge; thence northeasterly by line parallel to the pier-head line about 970 feet, and by an arc of a circle of 325 feet radius turning westerly to an intersection with the pier-head line on the south side of Bass Creek; thence it is coincident with the pier-head line to and along the easterly side of Eastern avenue and the northerly side of Bass Creek to the west side of Marginal street; thence the bulkhead line turns easterly and northerly by the arc of a circle of 315 feet radius and a tangent thereto to a point in the side of Willoughby street produced easterly, distant 210 feet from the west side of Marginal street; thence by a straight line to the north side of Dana street 470 feet easterly from the east side of Marginal street; thence to a point in the south side of Louis street 615 feet easterly from the east side of Marginal street; thence follows the southerly side of Louis street prolonged to its intersection with the pier-head line; thence the bulkhead line is coincident with the pier-head line to Slade's mill-dam.

Easterly side of Chelsea Creek above Chelsea Street Bridge- Pier and Bulkhead Lines.

Beginning at the point K of the pier-head line in the westerly side of Chelsea Street Bridge, before described, the pier-head and bulkhead lines are coincident, and follow the high-water lines and the westerly side of the railroad embankment and trestle to Slade's mill-dam, as delineated on the chart.

VI. SHORE OF EAST BOSTON.

From Jeffrey's Point to Breed's Island· · Pier and Bulkhead Lines.

The legal line from the point A near Jeffrey's Point, East Boston, to the point B at Breed's Island, established by section 5, chapter 293, acts of the Commonwealth of Massachusetts of 1856, is recommended for adoption as the pier-head line, beyond which no pile structure shall extend.

Said point A "is in the southwesterly line of Sumner street extended southeastwardly, and 800 feet from the southeasterly line of Jeffrey's street; thence the line runs easterly to a point in the northeasterly line of Everett street continued southeasterly, and distant 1,610 feet from the southeasterly line of Jeffrey's street; thence the line runs northerly to a point in the line of the northeasterly side of Neptune street continued southeastwardly, and distant 1,500 feet from the southeasterly line of Shirley street; thence the line runs straight northeastwardly to the point B on the southwesterly shore of Breed's Island, distant 1,250 feet from the southeasterly line of Saratoga street extended northeastwardly, measuring at right angles therewith from a point distant 1,300 feet from the southwesterly line of Trumbull street."

A parallel line 600 feet in rear thereof is recommended for adoption as the bulkhead line, beyond which no solid filling shall hereafter be permitted.

[Approved June 2, 1890.]

VII. DORCHESTER BAY.

From South Boston to Moon Island.

For Dorchester Bay, between a point C at City Point and a point Y on Neponset River, the pier-head lines coincide with the lines now fixed by the laws of Massachusetts in chapters 293 of the acts of 1856, 351 of the acts of 1872, and 332 of the acts of 1873.

On the right bank of the Neponset, between the Neponset Avenue Bridge and the mouth, the pier-head line recommended follows the line established by the State in its general features, but modified to give a gradual increase of width to the water-way near the mouth, in accordance with the best modern practice in the case of tidal streams.

Between the mouth of the Neponset River and the sewerage outlet on Moon Island, the State has never defined harbor lines. This has been done by the Board, after several public meetings and full consultation with the riparian proprietors, in a manner which it is believed will protect the general interests of the harbor and serve the local needs of the district in question.

The lines which are recommended for adoption are defined as follows:

1. Pier-Head Lines.

The pier-head line commences at a point marked C, which is in the westerly line of P street, South Boston, extended southwardly, and 530 feet from the southerly line of Sixth street; thence southwestwardly again to the point D in the easterly line of M street extended southwardly, and 1,300 feet from the southerly line of Eighth street; thence westwardly, parallel with Eighth street, to the point E in the easterly line of Old Harbor street extended southwardly; thence southwardly 1,400 feet to the point F in the easterly line of Old Harbor street extended southwardly; thence eastwardly, making an angle of 104° (taken from a northerly to an easterly direction) with the line last described, to the point G in the easterly line of M street extended southwardly; thence 3,200 feet to the point H in the easterly line of M street extended southwardly; thence southwestwardly 2,320 feet, making an angle of 124° (taken from a northeastwardly to a southwestwardly direction) with the line last described, to a point marked X'; thence continuing 1,900 feet westwardly a little more southwardly, making an angle of 5° 15' with the line last described extended, to the point marked I'; thence westwardly in a straight line which, extended, would strike the east side of the embankment of the Old Colony Railroad 515 feet northwardly from the north side of the present

water-way through said embankment, to a point 500 feet eastwardly from the east side of said embankment, marked J2; thence southwardly 590 feet parallel to the east side of said embankment to a point marked K2; thence southeastwardly in a straight line to the point marked L, which is distant 200 feet from the northeasterly corner of Ranstead, Dearborn & Company's Wharf (as built in 1856), measuring at right angles with the northeasterly end of said wharf; thence southwardly to the point M, distant 1,350 feet from the northeasterly rail of the Old Colony Railroad, measuring at right angles therewith from a point distant 4,000 feet northwestwardly from the draw in its bridge over Neponset River; thence southeastwardly to the point N, distant 1,200 feet from said rail, measuring at right angles therewith from a point distant 3,300 feet northwestwardly from said draw; thence southeasterly to the point O, which is distant 1,460 feet from the said rail, measuring at right angles therewith from a point distant 2,670 feet northwestwardly from the said draw; thence southeastwardly again to the point P, distant 1,630 feet from said rail, measuring at right angles therewith from a point distant 2,150 feet northwestwardly from said draw; thence southeastwardly again to the point Q, distant 1,700 feet northeastwardly from said rail, measuring at right angles therewith from a point distant 1,600 feet northwestwardly from said draw; thence southeastwardly again to the point R, distant 1,590 feet northeastwardly from said rail, measuring at right angles therewith from a point 1,090 feet northwestwardly from said draw; thence southeastwardly to the point S, distant 1,340 feet northeastwardly from said rail, measuring at right angles therewith from a point distant 630 feet northwestwardly from said draw; thence southerly to the point T, distant 1,140 feet northeastwardly from said rail, measuring at right angles therewith from a point distant 380 feet northwestwardly from said draw; thence southwestwardly to the point U, distant 850 feet northeastwardly from said rail, measuring at right angles therewith from a point distant 270 feet northwestwardly from said draw; thence southwestwardly again to the point W on the southeastwardly corner of James Jenkins's Wharf, formerly so called; thence southwestwardly again to the point X on the southeasterly corner of W.

2. Bulkhead Lines.

The bulkhead line is coincident with the pier-head line from the point C to the point F.

From F it runs southwardly in a straight line to the point I, which is on the line which bisects the angle at G of the pier-head line and 600 feet west of the line G H of the pier-head line; thence, parallel to the pier-head line G H and 600 feet within it, to a point on the line bisecting the angle at H of the pier-head line; thence parallel to the pier-head line H X' for a distance of 1,300 feet; thence turning by an angle of 105°, measuring from an easterly to a northerly direction, and running 2,000 feet; thence turning by an angle of 105°, measuring from a southerly to a westerly direction, and running 600 feet; thence turning by an angle of 86°, measuring from an easterly to a southerly direction, and running 1,965 feet; thence turning an angle of 91° 15', measuring from a northerly to a westerly direction, and running 1,600 feet to a point marked II, which is at the intersection of two lines, one a line parallel to the pier-head line X' I2 and 600 feet within it, and the other parallel to the pier-head line I' J2 and 400 feet within it; thence parallel to the line I' J2 and 400 feet from it inland, to the easterly side of the Old Colony Railroad embankment; thence along the easterly side of said embankment to a point 160 feet southward of the draw-opening; thence eastwardly, parallel to K L of the pier-head line, to the point III.
