Lighthouses
The first beacon was placed on the headland in 1856. It was a
cylindrical tower, built up of cast-iron plates, erected near the edge
of the cliff, which is 87 feet high. The tower itself being 38 feet in
height, the focal plane of the beam was at an elevation of 125 feet
above the sea. It was erected jointly by the British and Newfoundland
Government authorities, although the maintenance thereof was entrusted
to Great Britain. In return for the provision of this warning, a tax
of one-sixteenth of a penny, or an eighth of a cent, per ton, was
collected in England from vessels passing the light. The beacon was not
particularly powerful, the ray being only of some 6,000 candle-power.
Some years ago the lighthouse was handed over to the Canadian
Government to be included in its service, together with the balance of
the fund which had accrued from the levy of the special tax. This sum
represented £20,579, or $102,895. The Canadian Government abolished the
light-due, and the surplus funds were absorbed into the general revenue
of the country.
The new owners, realizing the importance of the light, subsequently
decided to provide a new beacon of greater power to meet the demands
of shipping, which had increased amazingly. In 1907 this structure
was completed. It is a cylindrical tower, carried out in reinforced
concrete, 100 feet in height, surmounted by a lantern of the first
order with hyperradial apparatus. This is the largest type of optical
apparatus in use at the present time, and the ray of light produced by
an incandescent oil-burner and mantle is of 1,100,000 candle-power,
shed from an elevation of 195 feet above the water. The warning flash
of a quarter of a second every seven and a half seconds is visible from
a distance of nineteen miles. In addition, the fog-signalling apparatus
was brought up to date. The steam-whistle, which had sufficed up to
the date of reconstruction, was replaced by a diaphone of the greatest
power installed up to that time. This is set up about 250 feet south
of the lighthouse, with which it is connected by a covered passage.
The air required to emit the warning blast, lasting three and a half
seconds once in every half-minute, is compressed by the aid of steam.
By day the lighthouse is readily distinguishable from its red and white
vertical stripes, red lantern, and white dwelling with red roof, in
which the keepers have their quarters. To-day the station ranks as
one of the finest in the world, complying in every respect with the
requisitions for one of a first-class character.
