The castle of San Geronimo, San Juan de Porto Rico, was founded a century ago. It occupies a rocky point at the east end of San Juan Island, and year by year had been strengthened until, when the American ships appeared in the offing, it was thought important enough to garrison. Six guns were emplaced, two other gun mounts were found by our troops when they entered, and a hole was discovered extending from a dungeon fifteen feet toward the breastworks. This had been freshly dug, and, it is believed, was devised for the storage of explosives, that the citadel might be blown up when the boys in blue entered to take possession. That the fort was abandoned without resorting to this revengeful and unmilitary act may be due to the ghost. He would naturally be in evidence at such a time, and would do what he could to thwart the schemes of his enemies. For he gave his body to the worms fifty years or more ago. In the flesh he was a revolutionist, and had been dreaming vain things about liberty for his beloved island. It is not recorded that he ever harmed any one, or that his little insurrection attained the dignity of anything more than a rumor and an official chill, but the Spaniards caught him, threw him into the dark prison of this castle, and after he had undergone hunger, thirst, and illness, they went through their usual forms of trial and condemned him to death. This among the civilized would have meant that he would be sent to the gallows or the garrote; but this victim was alleged to have accomplices, and quite likely he was suspected of having a small fund; for the first thing to do when you overthrow a government, or want to, is to pass the hat. To secure the names of his fellow-conspirators, but more especially their money, the revolutionist was therefore consigned to the torture chamber, where the rack, the thumb-screw, the hot irons, the whip, and other survivals of the Inquisition were applied. When the officers had extorted what they wanted, or had made sure there was nothing to extort, the poor, white wreck of a human being was delivered by the judges to an executioner, and a merciful death was inflicted.
