Southwest Wolf Island Lighthouse was constructed in 1871 on the southeast point of Southern Wolf Island, and its light was displayed for the first time on November 20th of that year by Keeper William Cline, who was paid an annual salary of $500. The revolving light had two faces, each containing three No. 1 circular burner lamps set in twenty-inch reflectors, and produced a white flash every ninety seconds. The lighthouse consisted of a square wooden keepers dwelling with a square tower rising from its roof. The lantern room had an inside diameter of nine-and-a-half feet and twelve sides, each of which supported a single pane of large plate-glass. The distance from the weather vane atop the lantern room to the ground was thirty-five feet, while the light had a focal plane of 111 feet above the high water mark. A tank in the cellar of the dwelling was used to store water, and a shed was built on the north side of the dwelling in 1874 to shelter the dwelling from cold northerly and westerly winds.
During the winter of 1873, the keeper reported that the machinery responsible for revolving the light worked irregularly or stopped completely. A machinist, dispatched from Saint John to investigate the matter, determined that the problem was oil on the wheels congealing due to the intense cold, and the issue was resolved by placing a small stove nearby.
Now, Sir, in further explanation, I would say that these works were undertaken by me without direct instruction from the Department I admit, but clearly and solely in the interest of the Department and as being of vital importance and necessity for the better protection and safety of the property of the Department placed in this extremely isolated and dangerous part.
I trust then that the Department will see how useful, how efficacious they are for the purpose intended, and will consider that I, in my zeal and my desire to promote the interest of the Department, have but anticipated their wishes in this respect, and in all fairness and justice, will reimburse me for my outlay in its behalf.
The marine agent recommended that the department reimburse Keeper Snell the $331 he had spent for material and labor, as the work had “proved of great service and convenience to the department,” but only $160 was offered him in 1878.
Southwest Wolf Island Lighthouse was apparently built by the government without first obtaining ownership of the land, as Alexander T. Paul sent the following letter, dated July 4, 1878 and addressed from the Sherrif’s Office in St. Andrews, to Keeper Snell.
SIR, I am informed that you have been for several years using the Southern Wolf Island as if it belonged to you, by cutting the hay, and pasturing your cattle and sheep upon it. I never gave you any permission or authority so to do, and unless you make an arrangement without any delay, with my uncle Joshua Paul, who I have authorized to act for me in the matter, I shall take legal proceedings to recover from you damages as a trespasser upon my property, and that of my sister Mrs. Crosby, and shall also bring your conduct under the notice of the Minister of Marine and Fisheries. After arranging with my uncle for the time past, you will then have to take a lease of the part of the Island you may wish to occupy, on such terms as to the rent and payment of it, as you and he may agree upon.
My uncle's receipt for the amount which he and you may agree upon for the past, will be a sufficient release to you of all claim on my part, till the time you agree upon the amount.
Trusting you will attend to this without delay.
The keeper was supplied a hand fog horn in 1900 to be used whenever he heard the fog signals of vessels in the vicinity. In 1905, a third-order lens, illuminated by petroleum vapour burned under an incandescent mantle, was installed in the lantern room to produce a bright, white flash every five seconds.
The original 1871 Southwest Wolf Island was replaced by a skeletal tower in 1962. The present fiberglass tower dates from 1982.
