Yet, one other thing there was, that has point in this place; for when I sent my speech out into the night, using my brain-elements, I came to know that, whether I had a knowledge of the North, or no knowledge at the moment, yet did I turn oft with a sure instinction to that Direction. And of this, the Master Monstruwacan took very great note, and had me to experiment many a time and way, and so enclosed about with screens, or with bandages across mine eyes, that I could not, save by that inward Knowing, have any knowledge to point me the way. Yet would I turn Northwards very frequent, by a certain feeling; and seemed unable of speech, if I were turned otherwise by force. But when we asked Naani whether she had an unusualness in this matter, she could discover none; and we could but take note curiously of that which affected my habits; and which truly I set to the attracting of her spirit; for I had mind that she did be somewheres out that way in the darkness of the world; but yet was this no more than to suppose, as you perceive. And the Master Monstruwacan wrote a study of this matter of the Northwardness of my turning; and it was set out in the Hour-Slips of the Tower of Observation; and so it came to be copied by the Hour-Slips of the great cities, and made much comment, and much calling up to me through the home instruments; so that with this, and the speech that went about concerning my powers to hear, I was much in talk, and diversely pleased and oft angered by overmuch attention and importunity. And now, whilst I pondered this matter in all my spirit and being, how that I should some way come to Naani, there befell a very terrible thing. And in this wise must I tell it: It was at the seventeenth hour, when all the millions of the Mighty Pyramid slept, that I was with the Master Monstruwacan in the Tower of Observation taking my due turn. And sudden, I heard the thrilling of the aether all about me, and the voice of Naani in my soul, speaking. And I sent the Master-Word into the darkness of the world, and presently, I heard the solemn answer beating steadfastly in the night; and immediately I called to Naani with my brain-elements, to know what thing troubled her in her sleep. And her voice came into my spirit, weak and far and faint, and so that scarce I could make to hear the words. Yet, in a while I gathered that all the peoples of the Lesser Redoubt were in very deadly trouble; for that the Earth-Current had failed suddenly and mightily; and they had called her from her sleep, that she might listen whether we answered their callings by the Instrument; but, indeed, no calling had come to us.
