One of the figures dressed in green jackets, who seemed to be in authority, now advanced, and, after a moment's parley with Senor Perkins while the Excelsior's passengers were being collected from the different boats, courteously led the way along the wall of the fortification. Presently a low opening or gateway appeared, followed by the challenge of a green-jacketed sentry, and the sentence, "Dios y Libertad" It was repeated in the interior of a dusky courtyard, surrounded by a low corridor, where a dozen green-jacketed men of aboriginal type and complexion, carrying antique flintlocks, were drawn up as a guard of honor. "The Comandante," said Senor Perkins, "directs me to extend his apologies to the Senor Capitano Bunker for withholding the salute which is due alike to his country, himself, and his fair company; but fifty years of uninterrupted peace and fog have left his cannon inadequate to polite emergencies, and firmly fixed the tampion of his saluting gun. But he places the Presidio at your disposition; you will be pleased to make its acquaintance while it is still light; and he will await you in the guard-room." Left to themselves, the party dispersed like dismissed school-children through the courtyard and corridors, and in the enjoyment of their release from a month's confinement on shipboard stretched their cramped limbs over the ditches, walls, and parapets, to the edge of the glacis. Everywhere a ruin that was picturesque, a decay that was refined and gentle, a neglect that was graceful, met the eye; the sharp exterior and reentering angles were softly rounded and obliterated by overgrowths of semitropical creepers; the abatis was filled by a natural brake of scrub-oak and manzanita; the clematis flung its long scaling ladders over the escarpment, until Nature, slowly but securely investing the doomed fortress, had lifted a victorious banner of palm from the conquered summit of the citadel! Some strange convulsions of the earth had completed the victory; the barbette guns of carved and antique bronze commemorating fruitless and long-forgotten triumphs were dismounted; one turned in the cheeks of its carriage had a trunnion raised piteously in the air like an amputated stump; another, sinking through its rotting chassis, had buried itself to its chase in the crumbling adobe wall. But above and beyond this gentle chaos of defense stretched the real ramparts and escarpments of Todos Santos--the impenetrable and unassailable fog! Corroding its brass and iron with saline breath, rotting its wood with unending shadow, sapping its adobe walls with perpetual moisture, and nourishing the obliterating vegetation with its quickening blood, as if laughing to scorn the puny embattlements of men--it still bent around the crumbling ruins the tender grace of an invisible but all-encompassing arm. Senor Perkins, who had acted as cicerone to the party, pointed out these various mutations with no change from his usual optimism.
