On
13 November 1866 the Board of Trade forwarded a
copy of one of the resolutions come to unanimously
by the Committee appointed by the Mercantile Service
Association of Liverpool to consider the subject
of lighting the St George's channel. It was to
the effect that "The night light on Calf of
Man now so often enveloped in fog and so rendered
useless, to be removed to the Chicken Rock which
is one mile and a half out and is a rock of considerable
size and great danger".
This
was remitted to David Thomas Stevenson, Engineer
to the Commissioners, who agreed in his report on
the subject on 22 October 1867. The matter was referred
to Trinity House, who wrote on 21 November 1867 to
the Board of Trade recommending the proposal. Trinity
House emphasised that "the Calf of Man Lights
were not to be depended upon from the well known
prevalence of fog on the Calf even when other high
lands are clear", and that, as a result at the
distance of 8 miles they were insufficient to warn
vessels of their proximity to Langness. A light on
the Chicken Rock would be of great assistant to Mariners
navigating East, West and North of the Isle of Man.
On
6 April 1868 sanction to proceed was given by the
Board of Trade. However, it was not until 6 June
1873 that the last stone of the tower was laid.
On
29 April 1873 the Board of Trade conveyed to Trinity
House their statutory sanction to the proposal that "the
character of the light now in course of erection
as Chicken Rock should be revolving of the natural
colour and attain its greatest brilliancy every half
a minute and further to the requisite arrangements
for throwing from the same lighthouse a red sector
of the light to mark the path round Langness Point.
These arrangements can be carried out either by fixing
an auxiliary condensing apparatus, consisting of
small holophotes at the rear of the main apparatus,
in the lantern of the Lighthouse or by some other
method, which the optical skill of Messrs Stevenson
may advise".
There
was considerable correspondence and disagreement
between D T Stevenson and Trinity House regarding
the proposal to show a red arc from Chicken Rock
to make a track round Langness Point and to fit ten
holophotes in the lightroom. Mr Stevenson argued
that the red arc would be useless in hazy weather,
that there would be out of superficial reflections,
poor ventilation and the revolving plane would be
out of centre in the Lightroom. Trinity House refuted
these objections and stated difficulties could be
overcome by using a larger lantern with main apparatus
in centre and by using Calzo Oil instead of Paraffin.
Under protest the red arc and auxiliary apparatus
were fitted. However, experiments were carried out
which confirmed Mr Stevenson's opinions and when
the Chicken Rock Light was exhibited for the first
time on 1 January 1875, it was without the red auxiliary
and with the use of Paraffin instead of Calzo.
The
Commissioners, having inspected Chicken Rock Light
and the Shore Station at the Calf of Man in 1875,
recommended that the shore station be removed to
Port St Mary, where the boatman and crew lived.
Over
and above nothing could grow in the gardens "for
legions of rats".
A
fog signal was added about 1890.
On
the night of 23 December 1960 the lighthouse was
seriously damaged internally by fire and during 1961
detailed consideration was given to the problem of
the future status of the station and the provision
of navigational aids generally in the area.
The
proposal for a major light and fog signal on the
Calf Man was included provisionally in the Engineer's
new Works in September 1961 and the Commissioners
subsequently agreed that the matter be referred to
the Shipowners through this Advisory Committee for
consideration. The Secretary of the Committee later
reported a substantial majority in favour of the
proposal subject to a number of conditions including
the addition of a form of automatic fog on the Chicken
Rock.
The light was automated in 1961.
