All these investigations and results I learned as clearly as if I saw them with the eye, in the firlamai or division of the electric sense, one of the vast halls of Oomalefa. Here were all the instruments needed to develop the firla or aid it, and all those by which it sought deeper into the secrets of nature. Off the hall ran corridors and arcades, which were to the firla what picture and sculpture galleries are to the ocular imagination, supplying it with noble and pleasurable excitation, as the music domes touched the aural imagination. They had their passive firlamaic arts of beauty as well as their active. In one vast arcade they could sit and feel with their firlas the electric harmonies of any given tract of air or earth or ocean, the harmonies that play as it were on the surface; this was equivalent to gazing at landscapes, real or pictured, with the eye. In another there was firlamaic sculpture; in this were gathered the noblest achievements of their electric artists, who strove to concentrate into some definite form varied magnetic materials so as to stir the imagination through the firla to thoughts of the titanic harmonies of the universe. They gave this form beauty for the eye as well; but that was not the primary aim; the gazers, as they sat, preferred to turn their backs to the work; for then through the firla their imagination was thrown into an attitude of placid meditation which seemed to have before it some great spheral harmony of the stars. In a third series of lofty corridors there was continually proceeding what might be called firlamaic music. In two or three it was entirely instrumental. Great firlamans or electric organs, at each end of one corridor I entered, flashed out what was to me the most appalling medley of lightnings; the gleams crossed and interwove and changed mass and form as if it were a dance of meteors, now slow and stately like a minuet, again swift and brilliant and dazzling as if the stars of heaven had joined the lightnings in a bewildering yet harmonious ballet. At first I was stunned and blinded; but soon I felt dimly the ecstasy apparent in my neighbours. Their eyes gleamed with joy; to me some of them seemed almost in a delirium; they were unconscious of their immediate surroundings, for I spoke to Thyriel and received no answer, and her motion through the hall as we started to leave it was somnambulous. She told me afterwards that, though her firla was only in its infancy, she felt drawn up into the heavens as in a trance; she seemed to feel the worlds move around her and attract her into their spheral chant; her imagination dealt with interastral forces as with playmates from eternity; she leapt vast ages every moment, and spanned in a stride spaces which seemed to her common powers infinite. She would not rest till she could enjoy this macrocosmic orchestra to the full as her parents did; she would not let a day pass without such practice as would develop her firla to the utmost.
