Out of the thinning mists and the cloud of strange incense filed twin columns of giant black slaves with loin-cloths of iridescent silk. Upon their heads were strapped vast helmet-like torches of glittering metal, from which the fragrance of obscure balsams spread in fumous spirals. In their right hands were crystal wands whose tips were carven into leering chimaeras, while their left hands grasped long thin silver trumpets which they blew in turn. Armlets and anklets of gold they had, and between each pair of anklets stretched a golden chain that held its wearer to a sober gait. That they were true black men of earth's dreamland was at once apparent, but it seemed less likely that their rites and costumes were wholly things of our earth. Ten feet from Carter the columns stopped, and as they did so each trumpet flew abruptly to its bearer's thick lips. Wild and ecstatic was the blast that followed, and wilder still the cry that chorused just after from dark throats somehow made shrill by strange artifice.
