Griswold put a twenty-dollar bill into the black palm, and when the crap victim made out the figure of it by the glow of the furnace fires, his eyes bulged. "Gorra-mighty!" he gasped; and would have given it back. "No, keep it; it's yours. Do exactly as I have told you, and if I'm able to keep my date with you, I'll double it. But if I don't show up, remember--the bundle goes into the river just as it is. If you open it, it'll conjure you worse than any Obi-man you ever heard of." "No, _suh_! I ain't gwine open hit, Cap'm--not if dey's cunjah in hit; no, suh!" "Well, there is--the worst kind of conjure this old world has ever known. But it won't hurt you if you don't meddle with it. Keep your wits about you and be ready to grab it and run. Here we go." The pilot had found his wharfage and was edging the _Belle Julie_ up to it. The bow men paid out slack, and Griswold and the black, dropping from the swinging stage, trailed the end of the wet hawser up to the nearest mooring-ring. Though haste in making fast is the spring-line man's first duty, Griswold took a fraction of a second to look around him. The mooring-ring lay fair in the mock noonday of electric light, and there was no cover near it save a tarpaulined pyramid of sugar barrels. Up the levee slope the way was open to the one-sided river-fronting street; and beyond the tarpaulin-covered sugar were more freight pyramids, with shadowy alleys between them. Satisfied with what he saw, Griswold bade the negro keep watch and knelt to knot the hawser in the ring. The line was water-soaked and stiff, and in the momentary struggle with it his caution relaxed its eyehold on the pyramid of sugar barrels. The lapse was hardly more than a glance aside, but it sufficed. While the negro sentinel was stammering, "L-l-lookout, Mars' Cap'm!" the trap was sprung. In deference to the up-coming passengers from the _Belle Julie_, the two man-catchers tried to do their job quietly. But Griswold would not have it so, and he was up and had twisted himself free when a blow from a clubbed pistol drove him back to his knees. Half stunned by the clubbing, he still made shift to spring afoot again, to drop his handkerchief bundle and kick it aside, and to close with his assailants while the negro was snatching up the treasure and darting away among the freight pyramids. After that he had but one thought; to keep the two plain-clothes men busy until the negro had made his escape. Even this proved to be a forlorn hope, since the smaller of the two instantly broke away to give chase, while the other stepped back, spun his weapon in air, and levelled it.
