(Approved March 17, 1890.] FROM THE MOUTH OF THE RIVER TO MEDFORD STREET BRIDGE. South side of South Channel of Mystic River — Pier und Bulk head Lines. The pier and bulkhead lines are coincident, beginning at the northwesterly corner of the sea-wall of the United States navy-yard, and run westerly in a straight line to the present northwesterly corner of Holmes' Wharf; thence continue westerly in a straight line to the present northeasterly corner of Stone's Wharf; thence continue westerly, following and coinciding with the northerly face of said Stone's Wharf, and continue in the same direction to the present northeasterly corner of Clark & Smith's Wharf; thence continue westerly in a straight line to a point in the northeasterly line of Elm street produced northerly at the westerly end of said South Channel, and distant 150 feet southerly from the northwesterly corner of said channel as said channel is defined in chapter 481 of the acts of the general court of Massachusetts of the year 1855. This line coincides with the line established by the State in chapter 302, acts of 1874. South side of Mystic River — Pier and Bulkhead Lines. Beginning at the point where the southeasterly line of Johnson's Wharf extended to the North Channel intersects a line drawn from the northeasterly corner of Tuft's mill-pond to a point on Chelsea Bridge 700 feet northerly from the northerly side of the south draw in said bridge, the line runs easterly 820 feet by an arc of a circle curving northerly, and having a radius of 3,500 feet; thence continues easterly by a straight line tangent to said arc, and in such a direction that it shall pass through a point on the northwesterly side of said bridge 770 feet southerly of the southerly side of the north draw in said bridge, running by said straight line to a point 311 feet westerly of the westerly side of said bridge; thence running southeasterly by an arc of a circle turning southerly, and having a radius of 675 feet, said arc to be continued until a straight line drawn tangent to said arc would, if continued, pass through the northeasterly corner of the timber dock of the navy yard of the United States, said line tangent to be continued to the northerly side of the South Channel to a point 500 feet distant from said corner of said dock, and 817 feet distant from the easterly side of Chelsea Bridge by a line drawn at right angles with said bridge; thence running westerly by a straight line which extended would strike the line of the northeasterly side of Elm street produced 500 feet from the northerly side of Medford street, measured on said northeasterly side of Elm street, to a point 320 feet easterly from said northeasterly side of Elm street produced ; thence running southwesterly by an arc of a circle turning southerly, and having a radius of 600 feet, to a point on said easterly line of Elm street extended northerly 375 feet from the northerly side of Medford street. This line coincides with the line established by the State in chapter 481, acts of 1855, and chapter 150, acts of 1867. The portion of the line thus described between its point of beginning and where it first intersects the easterly line of Elm street produced northerly to the channel, and a straight line drawn from this point of beginning to the northeasterly corner of Tuft's mill-pond, is to be considered a pier-head line beyond which no pile structure shall be extended; and the remainder of the line above described is to be considered a bulkhead line beyond which solid filling shall not hereafter be permitted. Beginning again at the point where the line above described first intersects the northeasterly line of Elm street produced northerly to the channel, the bulkhead line follows the line of the northeasterly line of Elm street produced northerly, in a southerly direction to a point 600 feet distant from the pier-head line measured on a line at right angles thereto; thence runs westerly, in a line parallel to and 600 feet inside of the pier-head line, to the easterly face of the wall bounding Tuft's millpond on the east; thence along the face of this wall to the northeasterly corner thereof; thence the pier and bulkhead lines are coincident, and follow the channel-face of Tuft's mill-pond wall to the southerly abutment of the Malden Bridge; thence along this solid abutment and its northeasterly face to the north corner thereof; thence in a straight line which, if produced, will strike the easterly corner of the solid filling of the Boston and Maine Railroad Company's coal dock above the Eastern Railroad bridge, to the easterly face of the Eastern Railroad bridge; thence along the easterly face of this bridge to a point distant 375 feet northeasterly from the northeasterly corner of the solid abutment of said last-named bridge on the southerly side of the channel ; thence the pier-head line runs northwesterly to a point on the easterly side of the bridge of the Boston and Maine Railroad, distant 625 feet northerly from the northeasterly corner of the solid abutment of said last-named bridge on the southerly side of the channel; and the bulkhead line between the Eastern Railroad Bridge and the Boston and Maine Railroad Bridge is parallel to and 30 feet within said pier-head line. The pier-head line so described between the Eastern and Boston and Maine Railroad bridges coincides with the line established by the State in chapter 231 of the acts of 1873. The line of the channel wall of Tuft's mill-pond was established as a harbor line by chapter 293 of the acts of 1856. Betweeu the southeasterly line of Johnson's Wharf prolonged and Tuft's mill-pond, and between the Malden and Eastern Railroad bridges, the State has established ro harbor line. Beginning again at the point of intersection of the bulkhead lines of the northerly side of the South Channel and Main Channel, said point being 500 feet in a northerly direction from the east corner of the timber dock of the United States navy-yard, the pier-head line coincides with а the bulkhead line of the Main Channel for a distance of 605 feet; thence runs northerly in a straight line to a point which is distant 385 feet easterly from the easterly side line of said avenue, measuring at right angles to said avenue from a point in the said easterly side line, which latter point is distant 100 feet southerly from the top face of the northerly abutment of said avenue, measuring said latter distance on said easterly side line; thence turning and running northwesterly in a straight line to a point in the easterly side line of said avenue extended northerly, which point is distant 65 feet northerly from the top face of the abutment aforesaid, measuring on said easterly side line so extended. Then beginning again at a point in the westerly side line of said avenue extended northerly, which point is distant 65 feet northerly from the top face of, the abutment aforesaid, measuring on said westerly side line so extended; thence running westerly in a aight line to a point which is distant 30 feet northerly from the northwesterly angle of the sea-wall of said corporation as now built; thence turning a little and running still westerly in a straight line parallel to and 30 feet distant northerly from the top face of the northerly sea-wall of said corporation as the same is now authorized to be built, until the said straight line intersects the easterly side line of Elm street extended northeasterly; thence southerly along said line of Elm street to the bulkhead line. Said pier-head line coincides with the line established by the State in chapter 272 of the acts of 1885. The pier-head line on the north side of the South Channel is parallel to the bulkhead line and 35 feet outside of it, as established by the State in chapter 19 of the acts of 1859. Chelsea Side of Mystic River and Chelsea Creek between Chelsea Bridge and Meridian Street Bridge — Pier and Bulkhead Lines. The pier-head line coincides with the line established by the State in chapter 311 of the acts of 1887, and is as follows: Beginning at a point on the southeasterly side of Chelsea Bridge at the southeasterly corner of the solid portion of said bridge, as now built, at the Chelsea end thereof; thence running southeasterly down Mystic River, making an angle of 73° 6' taken from a southwesterly to a southeasterly direction with the southerly side of said bridge, and passing through the southwesterly corner of Black's Wharf, 697.57 feet to a point at or near the angle of junction of Chelsea Creek with Mystic River; thence turning 78° 58' 11" to the east and north and running northeasterly up Chelsea (reek, passing through the southeasterly corners of Gerrish's Wharf and Bisbee's Wharf, 1,196.03 feet to a point on the westerly side of Meridian Street Bridge, marked by an iron plate and copper tack, and distant 23.3 feet southerly from the abutment of said bridge at the Chelsea end thereof. The bulkhead line is parallel to and 300 feet within the pier-head line. North side of Mystic River between Chelseu Bridge and Boston and Maine Railroad Bridge — Pier and Bulkhead Lines. Beginning at a point where a line drawn on the north side of the channel, parallel to and 1,200 feet distant from the bulkhead line on the south side of the channel, intersects the westerly line of the north abutment of Chelsea Bridge, marked M on Boston Harbor Line Board Sheet * J," the pier-head line runs westerly in said parallel line 2,000 feet to a point marked N. Beginning again at a point marked ( in said parallel line, at the point of its intersection with the easterly line of Elm street produced across the river, and running westerly in said parallel line 2,475 feet to a point marked P; thence in the arc of a circle curving 'west and north, and tangent to said line at said point P, with a radius of 1,600 feet, to its intersection with the westerly line of the Malden Bridge abutment; thence northwesterly in a straight line to a point at the mouth of the Malden River marked Q, said point being 710 feet from the easterly side of the Boston and Maine Railroad Bridge, measuring at right angles thereto from a point 570 feet northerly of the south end of the north abutment of said bridge.
