Nature appeared to capitulate after this terrible assault, and work proceeded rapidly. The crest of the rock was removed and levelled off, to form an excellent platform for the reception of the beacon and other buildings. An inclined tramway was excavated out of the rock-face, communicating with the landing-stage, to facilitate the haulage of the light-keepers’ necessities, and then the arrangements for the completion of the building were hurried forward. When the public saw that the work was being accomplished without loss to life or limb, and that the plucky little party of toilers weathered the gales, an intense interest was manifested in the undertaking. The foreman was provided with an international code of signals, and passing vessels, as an act of courtesy and in recognition of the work that was being done to further their safety, always stood towards the rock to render assistance in case it was required. The workmen appreciated this feeling, and on two occasions, during dense fog, intimated to captains who had lost their way, and were groping blindly round the rock, that they were venturing into dangerous waters. The warning was primitive but effective. It comprised the explosion of giant-powder cartridges over the sea in the direction whence the ships’ sirens sounded. In both instances the navigators heard the signals in the nick of time, and were able to steer clear. The lighthouse itself comprises a group of buildings for the keepers, from which rises a square tower 48 feet in height, bringing the light 132 feet above mean high-water. The dwelling is built of stone, measures 48 feet by 45 feet, and is one story in height. In addition there is an extension for housing the powerful siren and its machinery. The building contains adequate living-quarters, together with storage rooms and a kitchen. As this light is particularly lonely, four keepers are stationed on the rock, and their rooms each have a clear length of 12 feet by 10 feet wide. Also, as the rock is so difficult to approach, and relief may suffer extreme delay from adverse weather, sufficient provisions are stored to insure full rations for six months. The light is of the first order, of 160,000 candle-power, and is visible at a distance of eighteen miles in clear weather. It is a brilliant white flashing beam, occurring once every five seconds, the flash being of two seconds, followed by an eclipse of three seconds. The fog-siren is likewise of the first order, driven by steam-engines. This plant is in duplicate, and the signal is given every forty-five seconds, the blast being of five seconds, followed by silence for forty seconds.
