Lighthouses
Subsequently this novel and, so far as it went, efficient method of
“quick transit” was superseded when the men on the rock got their big
derrick to work. The long arm of this appliance leaned over the water
far enough to pick up the goods direct from the deck of the vessel
moored off the rock. This system was quicker, and enabled the goods to
be got ashore unsoiled.
The first men to land found the rock in the occupation of sea-lions,
who swarmed its scaly sides in huge numbers, even making their way to
the crest to bask in the sunshine. These tenants at first resented the
white man’s invasion, and were somewhat troublesome; but at last they
recognized that their eviction was certain, so suddenly deserted in a
body to another equally wild spot farther south.
The first task was the preparation of the site for the building. The
fist-like overhanging crest was attacked to prepare a foundation,
thereby reducing the height from 120 to 91 feet. The rock surface was
scarred and riven in a fantastic manner, owing to the scouring action
of the waves eroding the soft portions leaving the hard rock behind in
the form of needles, scales, and ugly crevices. The outer part of the
rock, moreover, was found to be of an unreliable character, being more
or less rotten, while the core, on the other hand, was intensely hard,
and promised an excellent foundation for the beacon. The superfluous
mass was removed by blasting, this being carried out with extreme care
and in small sections at a time. The largest blasts did not remove
more than 130 cubic yards, or tons, of débris at one time. This slow
blasting, by handfuls as it were, was necessary so as not to shatter or
impair the solidity of the heart of the rock, which was to support the
buildings.
Drilling and blasting were carried out in the face of great
difficulties. Rain, rough seas, spray, and heavy winds, combined
to thwart the little band of workers toiling strenuously in solemn
loneliness upon this bleak crag. Often days would pass without any
tangible impression being made upon the surface. The drilling holes
would be swamped, and unless care was observed the powder charges ran
the risk of being damped and rendered impotent or uncertain in firing.
In the attack upon the crest the workmen distributed themselves around
the crown. On the precipitous side, as there was not a friendly ledge
on which to secure a foothold to work the drills, bolts were driven
into the rock-face, from which staging was suspended by ropes, and
on this swinging, crazy foothold the men drove their tools with salt
fleece whirling round them.
