there are many dangerous shoal heads within this area.
Mariners are warned against crossing the above-mentioned
area. A clear chan. is believed to exist between it and the
S. pt. of Guam Isl. Oct.

COLUMBIA RIVER ENTR.—On 5th Sept., 1903, the following
alterations were to be made in the buoys at the entr. to the
river: 1. The S. chan. buoy, black, can, marked S.C., 3⁹⁄₁₀
miles S. 26° W. from Cape Disappointment Lt.-h. (46° 16½′
N., 124° 3¼′ W.), disc. 2. The S. chan. shoal buoy, can,
black and red hor., 3²⁄₁₀ miles S. 31° W. from Cape Dis-
appointment Lt.-h., disc. 3. The Outside Bar Whistle Buoy
moved to a position with Cape Disappointment Lt.-h.
N. 31° E., and Pt. Adams (disc.) Lt.-h. N. 87° E. 4. The

S. 35° E. 2½ miles to a position with Cape Disappointment
Lt.-h. N. 26° E. 3⁹⁄₁₀ miles. It marks the entr. to the pre-
sent S. chan. The letters M.S. are no longer painted on the
buoy. 5. The bar buoy, conical, black and white vert.,
2⁶⁄₁₀ miles S. 61° W. from Cape Disappointment Lt.-h , disc.
6. Clatsop Spit buoy No. 0, red, conical, 2⁸⁄₁₀ miles S. 50° W.
from Cape Disappointment Lt.-h., replaced by a black can
buoy, and will in future be known as the Peacock Spit
buoy No. 0. 7. A black and white vert., conical, lt.-buoy,
exh. occ. lt., est. in a position with Cape Disappointment
Lt. N. 20° E. 2⁶⁄₁₀ miles. Oct.

The Corporation of the Borough of Gore authorised to erect
Electric Lines from Mataura to Gore and within the
Borough of Gore.

IN exercise of the power and authority conferred upon me
by “The Electric Lines Act, 1884,” I, Joseph George
Ward, the Electric Telegraph Commissioner appointed under
the said Act, do hereby authorise and license the Mayor,
Councillors, and Burgesses of the Borough of Gore (herein-
after referred to as “the Corporation”) to erect, construct,
lay down, and maintain electric lines for lighting and power
purposes along the main road between the works, situate in
the Borough of Mataura, of the Southland Frozen Meat and
Produce Export Company (Limited) and the Borough of
Gore, and through the several streets in the Borough of
Gore, which lines are shown on the plans marked A and B,
deposited in the office of the Superintendent of Electric
Lines, and on which plans the electric lines are indicated by
red lines, and which are signed by me as such Commissioner
as aforesaid, subject to the following conditions, viz.:—

1. Single-phase alternating current shall be used in the
   transmission of electrical energy between Mataura and Gore,
   and in its distribution within the Borough of Gore.

2. Current shall be generated at Mataura, in the works of
   the Southland Frozen Meat and Produce Export Company
   (Limited), for delivery to the transmission-wires at a frequency
   of 55 to 60 complete cycles per second, and at a pres-
   sure not exceeding 5,000 volts.

3. At the generating-station a properly equipped non-
   inflammable switchboard mounted upon a substantial iron
   frame shall be provided, and the current shall be conveyed
   through automatic circuit-breakers from the switchboard to
   the transmission lines by highly insulated cables carefully
   protected from liability of interference or of injury.

4. The “extra-high-pressure” transmission-wires for a
   distance of 40 chains from the generating-station at Mataura,
   and for a similar distance from the distributing-station at
   Gore, shall consist of cable which shall be of stranded copper
   wire, equivalent to a solid copper wire of No. 7 standard wire
   gauge, insulated throughout the distances named with
   2,500 megohms per mile grade of vulcanised rubber insula-
   tion, taped, braided, and treated so as to be impervious to
   moisture. The cables shall be suspended by raw-hide hangers
   from a suitable steel bearer wire, which shall be securely
   attached to triple-shed porcelain insulators.

5. The transmission-wires, excepting such parts as are
   required to be of suspended insulated cable, may be bare,
   and shall consist of hard-drawn copper of not less than No. 7
   standard wire gauge. They shall be run throughout on
   strong wooden poles of totara or other approved timber, the
   spans between which shall not be of greater length than
   2 chains, and they shall be supported on high-tension triple-
   shed highly vitrified porcelain insulators, with galvanised-
   iron stems fitting into cross-arms of suitable material and
   cross-section.

6 The minimum height of the transmission wires above
the ground shall be 18 ft., except at road or railway crossings,
where the minimum height shall be 22 ft.

7. Below the transmission-wires two telephone copper
   wires shall be run. These wires may be bare, may be
   attached to swan-neck insulators, and shall be not smaller
   than No. 14 standard wire gauge. They shall be not less
   than 16 ft. above the ground at their lowest point, and at all
   road or railway crossings their minimum height above the
   ground shall be 20 ft.

8. Only the transmission-wires, which may be duplicated,
   and the two telephone-wires shall be permitted to be run on
   any of the poles used for the support of the 5,000-volt circuit.

9. The transmission-wires where they enter the generating
   and distributing stations shall be securely and safely led in,
   and protection against lightning, by Siemen’s horn lightning-
   guards or other approved high-tension lightning guards with
   choking-coils, shall be provided on both wires at each end of
   the line, and at all those points along the line where bare
   wire connects to cables. The telephone-wires shall be suit-
   ably guarded against lightning, and shall be fused so as to
   prevent all possibility of injury resulting to any person using
   the telephone should a power-wire fall into contact with
   them.

10. Where wires on the transmission line cross other wires,
    either telegraph or telephone, they shall cross at a safe height
    above, but in no case at a less height above the ground than
    20 ft. The poles at all such crossings, and at all road and
    railway crossings, shall be specially strong, and no span shall,
    where practicable, exceed 1 chain in length. The crossing
    shall be as nearly at a right angle as possible, and double
    cross-arms with insulators shall be used on the poles on each
    side of such crossing. All the wires on the transmission line
    shall be highly insulated throughout the whole length of such
    crossing with 2,500 megohms per mile grade of vulcanised
    rubber insulation, and shall be suspended by raw-hide
    hangers from steel bearer wires, which shall be effectively
    attached to triple-lipped porcelain insulators. Where tele-
    graph or telephone wires are crossed over they also shall be
    insulated to the satisfaction of the Electric Telegraph Com-
    missioner, and at the Corporation’s expense.

11. The transmission line shall be on the opposite side of
    the road or street to that on which the telegraph or telephone
    lines are run, and shall be patrolled throughout its whole
    length at least twice a week; and its insulation shall be so
    maintained that the maximum leakage shall not exceed 0·02
    of an ampere. Tests shall be made daily and recorded.

12. Where the line passes in the vicinity of the Charlton
    School, notice-boards shall be prominently placed pointing
    out the danger of interfering with the wires, and warning all
    persons against doing so in any way.
