"I stuffed the note back in my pocket. The more I thought about the whole affair the less I liked it. The flirtation had begun harmlessly enough, and Julie was as lovely and appealing as a figure in a fairy-tale, but there are unpleasant aspects to most fairy-tales, and this was no exception. That scene last night when she had seemed to argue with a full-grown cottonmouth, and the mysterious appearance of the snake whenever I spoke of breaking my promise to go back to her--there was something too much like black magic in it. Now she addressed me as her adored and signed herself for eternity; finally named a graveyard as our rendezvous. Things had become a little bit too thick. "I was standing at the corner of Canal and Baronne Streets, and crowds of office workers and late shoppers elbowed past me. 'I'll be damned if I'll meet her in a cemetery, or anywhere else,' I muttered. 'I've had enough of all this nonsense----' "A woman's shrill scream, echoed by a man's hoarse shout of terror, interrupted me. On the marble pavement of Canal Street, with half a thousand people bustling by, lay coiled a three-foot water moccasin. Here was proof. I'd seen it twice in my room at the hotel, but I'd been alone each time. Some form of weird hypnosis might have made me think I saw it, but the screaming woman and the shouting man, these panic-stricken people in Canal Street, couldn't all be victims of a spell which had been cast on me. 'All right, I'll go,' I almost shouted, and instantly, as though it been but a puff of smoke, the snake was gone, the half-fainting woman and a crowd of curious bystanders asking what was wrong left to prove I had not been the victim of some strange delusion. * * * * * "Old Saint Denis Cemetery lay drowsing in the blue, faint twilight. It has no graves as we know them, for when the city was laid out it was below sea-level and bodies were stored away in crypts set row on row like lines of pigeon-holes in walls as thick as those of mediæval castles. Grass-grown aisles run between the rows of vaults, and the effect is a true city of the dead with narrow streets shut in by close-set houses. The rattle of a trolley car in Rampart Street came to me faintly as I walked between the rows of tombs; from the river came the mellow-throated bellow of a steamer's whistle, but both sounds were muted as though heard from a great distance. The tomb-lined bastions of Saint Denis hold the present out as firmly as they hold the memories of the past within. "Down one aisle and up another I walked, the close-clipped turf deadening my footfalls so I might have been a ghost come back to haunt the ancient burial ground, but nowhere was there sign or trace of Julie. I made the circuit of the labyrinth and finally paused before one of the more pretentious tombs. "'Looks as if she'd stood me up,' I murmured. 'If she has, I have a good excuse to----'
