The ships in the two inner circles then began to move slowly, and passed in two wavy lines alternately in front of one ship and behind the next ship in the outer circles, the serpentine movement gradually becoming more and more rapid; and most wonderful changes of colour were produced by the passage of the vessels past those lighted with lamps of another colour. Swifter and swifter became the speed until it seemed utterly impossible that these intricate movements could go on without resulting in a series of collisions and disasters. Yet, with all this bewildering whirling, twisting, and intertwining, the ships were guided on their courses with consummate skill and with an unerring accuracy which was marvellous to behold. Another shake of the aerial kaleidoscope and the vessels were seen drawn up in three parallel lines on the east and three on the west. Then the search-lights again flashed out, filling the whole intermediate area of the sky with beams of brilliant coloured light, which were caused to oscillate sideways and overlap, producing a most gorgeous intermingling of glowing colours. The Martians certainly had a complete understanding of all the peculiarities connected with mixtures of coloured lights. Up to this time silence had reigned, for no sound came to us from this vast aerial fleet; but now there burst forth from both ranks of vessels strains of music of such ravishing sweetness that I and my two colleagues were quite overwhelmed. It seemed as though our mortal bodies were completely etherealised by the thrilling melodies which floated down to us from the upper air. This was not all. When on the earth we had read of attempts to connect musical tones and chords with the chromatic scale of colour, it being suggested that each musical sound had its own distinctive tone-colouring. Now we saw it practically demonstrated, for each chord of music was accompanied by changes in the colours of the search-light beams; and on comparing notes afterwards John and I found ourselves agreeing that the colours shown appeared exactly to interpret what our inner consciousness seemed to evolve, but which we could not have expressed in words. It was like a scene of enchantment as we watched those immense bands of glowing colours changing so rapidly and synchronising with the chords of music. Merna informed us that the lights of each vessel were electrically controlled from the keyboard of one of the musical instruments on the ship. This was followed by a piece resembling a grand chorale: then an intricate fugue was performed, the several movements being taken up in succession by the ranks on each side alternately, and apparently flung to and fro from one side to the other of that vast area in magnificent sequences and variations until it seemed that our human nature was so uplifted, and we were so filled with ecstasy, that we could bear no more.
