"But light-houses are sometimes destroyed," Sidney whispered. "Anything like that doesn't happen once in a hundred years. I reckon you're thinkin' of Minot's Ledge Light, on the Massachusetts coast, which was carried away in 1851; but in that case it was shown pretty clearly the mischief was done through the keepers' disobeying orders." "Tell me about it, sir." "Wa'al, Sonny, I allow it ain't overly cheerful talk on a night like this; but so long as it's in your mind I don't s'pose it'll make matters seem worse if we go over the story. Nobody knows jest what time, on the night of April 16th, the tower was carried away; but it's reasonable to allow it was done about high water, which was an hour after midnight. It was built on iron piles set into the rock, instead of bein' a solid tower sich as are put up nowadays. I've heard them as should know, say that keepers weren't held up to the rules an' regerlations as strict as they are now, an' them as were in charge of Minot's Ledge Light had built a platform well down below the livin' rooms, where they could stow anything which it might not be convenient to keep inside. Here's what the Government engineer, who was sent to look after the matter, said about it," and Captain Eph, opening a book which lay near him, read the following: "'The keepers had improperly built a sort of deck or platform, upon which were placed heavy articles, such as fuel, water-barrels, etc., which should have been in the store-room, designed for their reception. The deck, in addition to the weight placed upon it, was fastened to the piles and braces, thus offering a large surface, against which the sea could strike. "'In addition to this, the keepers had attached a five-and-a-half inch hawser to the lantern deck, and anchored the other end to a granite block, weighing, according to their account, seven tons, placed upon the bottom at a distance of some fifty fathoms from the base of the tower. The object of this was to provide means for running a box or landing-chair up and down; but it is very clear that so much surface exposed to the moving sea had the same effect upon the light-house as would have been produced by a number of men pulling at a rope attached to the highest part of the structure, with the design of pulling it down. "'At 4 o'clock on Wednesday afternoon, the 16th, or ten hours before the light fell, the platform above mentioned came ashore at Cohasset. As this was forty-three feet above the line of low water, and twenty-eight feet above high water, spring tides, the sea had at that time reached within seven feet of the base of the store-room of the light-house. Without undertaking to speculate upon the probable shock that the structure must have received from the effect of the sea upon a platform fastened to the piles forty feet above the rock, it is enough to know that the sea had reached within seven feet of the body or solid part of the structure.
