Lighthousekeeper: Rules and Regulations 2


Disaster near a lighthouse: engraving


The lamp shall be kept burning bright and clear every night from sunset to sunrise and in order that the greatest degree of light may be maintained throughout the night, the wicks must be trimmed as often as necessary to ensure steady maintenance of the light at its best. The keeper who has the first watch shall take care to trim the oil valves so as to let the oil flow into the burner a sufficient time before lighting.

The lightkeeper shall keep a constant and regular watch in the lightroom throughout the night. There are to be two night watches. The 1st watch to begin at sunset and to continue until midnight. The 2nd watch to be from midnight until the period of extinguishing the light. Before leaving the lightroom the keeper having the 2nd watch shall extinguish the light, turn off the oil, and close the curtains of the lantern. The lightkeepers are to take alternate watches in such manner that he who has the 1st watch one night shall have the 2nd watch next night.

Daily duty shall be laid out in 2 shifts, taken alternately, he who has 1st watch at night shall take 1st shift and he who has 2nd watch shall take the 2nd shift.

Lighthousekeepers: Rules and Regulations


A Lighthousekeeper and his family


Lighthousekeeping was no sinecure. Keepers fulfilled a vital role and carried a heavy responsibility for maintaining the light.  Every aspect of their duties was covered by the printed Rules and Regulations of which every keeper received a copy. It would be his ‘bible’ for the entire period of his service.

‘Rules for the Proper Care and Maintenance of the Light on the Bluff at Port Natal’ would have been my ancestor Thomas Gadsden’s daily reading, in-between all his other activities. The Rules were published in each annual edition of the Natal Almanac and Yearly Register and changed little from their inception to the phase after Thomas’s death.

The following instructions give some idea of a keeper’s many and varied tasks:

Great care is to be bestowed in keeping everything connected with the Lighthouse in a thorough state of cleanliness and efficiency, as the optical apparatus, consisting of lenses and prisms, suffers materially from the effect of dust injuring its polish, and as the proper burning of the lamp is impaired by a want of due attention to its cleanliness and the state of the works.

The glass lenses and prisms are to be cleaned every day, being first freed from dust by a feather or other soft brush and then rubbed down with a soft chamois skin, free from anything that would injure the polish of the glass. If the glass becomes greasy it is to be first washed with a linen cloth steeped in spirits of wine and afterwards carefully dried with a soft dry linen cloth or rubber free from all dust and gritty particles and finally rubbed with a fine chamois leather.

The brass work of the lamps is to be kept clean by polishing with whitening or suitable  polishing paste. Great care is to be taken that the lamp is accurately in the focus of the illuminating apparatus and that the flow of oil is such that a proper height of flame is maintained. If the flame cannot be maintained to its proper height, the lightkeeper must immediately examine whether or not it is due to want of cleanliness of the burner, want of proper flow of oil, or any imperfection in the wicks or oil, or the draught of the lamp’s chimney. The wicks should be gradually raised during the first 20 minutes of burning until the flame reaches the proper height to give the maximum amount of light.

Note: the mechanical lamps being constructed to give a plentiful overflow from 3-4 times the quantity consumed, the wicks char but slowly. The lamp should burn, when in good order, the whole night without the works requiring to be touched when paraffin oil is used. [Paraffin came into use about mid-19th century]

All moving parts in the revolving machinery and mechanical lamps must be kept scrupulously clean. Ventilator to be opened to admit sufficient supply of air to ensure  proper burning of the light and prevent condensation. Storm frames are to be kept in readiness for immediate use in case of accident.

The windows of the lantern are to be regularly cleansed every day and washed with water when necessary to remove the sea spray or other obstructions to the passage of the light, and for the same reason they are to be rubbed during the night when they become obscured by condensation or sweating.
