|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.
