"The Priest of the Temple of Nagaya,"--went on Sah-luma--"are the greatest scientists in the world, with the exception of the lately formed Circle of Mystics, who it must be confessed exceed them in certain new lines of discovery. But setting aside the Mystic School, which it behoves us not to speak of, seeing it is condemned by law,--there are no men living more subtly wise in matters pertaining to aerial force and light-phenomena, than the Servants of the Secret Doctrine of the Temple. All seeming-marvellous things are to them mere child's play,--and the miracles by which they keep the multitude in awe are not by any means vulgar, but most exquisitely scientific. As, for instance, at the great New Year Festival, called by us 'The Sailing-Forth of the Ship of the Sun,'--which takes place at the commencement of the Spring solstice, a fire is kindled on the summit of the highest tower, and a Ship of gold rises from the centre of the flames, carrying the body of a slain virgin eastwards, . . 'tis wondrously performed! ... and I, like others, have gaped upon the splendor of the scene half-credulous, and wholly dazzled! For the Ship doth rise aloft with excellent stateliness, plowing the air with as much celerity as sailing-vessels plow the seas; departing straightway from the watching eyes of thousands of spectators, it plunges deep, or so it seems, into the very heart of the rising Sun, which doth apparently absorb it in devouring flames of glory, for never again doth it return to earth, . . and none can solve the mystery of its vanishing! 'Tis a graceful piece of jugglery and perfectly accomplished, . . while as for Oracles [Footnote: The Phonograph was known and used for the utterance of Oracles by one Savan the Asmounian, a Priest-King of ancient Egypt.] that command and repeat their commands in every shade of tone, from mild to wrathful, there are only too many of these, . . moreover the secret of their manufacture is well known to all students of acoustic science. But concerning the Black Disc in Lysia's hall, it is a curiously elaborate piece of workmanship. It corresponds with an electric wheel in the Interior Chamber of the Temple, where all the priests and flamens meet and sum up the entire events of the day, both public and private, condensing the same into brief hieroglyphs. Setting their wheel in motion, they start a similar motion in the Disc, and the bright characters that flash upon it and disappear like quicksilver, are the reflection of the working electric wires which write what only Lysia is skilled to read. From sunset to midnight these messages keep coming without intermission,--and all the most carefully concealed affairs of Al-Kyris are discovered by the Temple Spies and conveyed to Lysia by this means. Whatever the news, it is repeated again and again on the Disc, till she, by rapidly turning it with a peculiar movement of her own, causes a small bell to ring in
