As it began to grow dark, they lighted up the camp. This was accomplished by little metallic posts that had been set around at intervals. Each had a tiny coil of wire suspended at its top, which became incandescent and threw out a reddish-green light. Around each light was a square black wire cage some three feet in diameter. I conjectured that these lights used the same ray as the projectors, only in a different form, and that the cage was to protect any one from going too close. The light from these illuminators was much the same in aspect as the ray, except that it seemed to diffuse itself readily and carried only a comparatively short distance. The scene now, under this red-green glare, was weird in the extreme. The work all about me went on steadily. The Mercutians were all dressed in white furry garments now--I concluded because of the cold--with the exception of those who had on the suits and helmets of black. The reddish-green light made them all appear like little gnomes at work. Indeed, the whole scene, with its points of color in the darkness, and the huge monstrous shadows all about, was more like some fantastic picture out of a fairy book than a scene on this earth. Soon after nightfall Tao stopped me, and one of his men brought me something to eat. I still had the slices of bread and meat in my pocket, but, thinking I might need them later on, I kept them there. Tao and I sat down near one of the lights and ate together. We were served by one of the men. My guard still kept close at hand. The food was nothing more than hard pieces of baked dough and a form of sweet something like chocolate. For drink there was a hot liquid quite comparable to tea. This was served us in small metal cups with handles that seemed to be insulated from the heat. This meal was brought to us from inside the vehicle. While we were eating I could see many of the Mercutians going inside and coming out with pieces of this food in their hands, eating as they worked. Quite obviously the business of assembling their apparatus was uppermost in the minds of all of them. The whole atmosphere about the place, I realized now, in spite of the opposite effect their dragging footsteps gave, was one of feverish activity. When we had eaten Tao seemed willing to sit quiet for a while. My efforts to talk to him amused us both greatly, and I noticed with satisfaction that he seemed to trust me more and more. Finally my guard spoke, asking permission, I judged, to leave us and go have his dinner. My heart leaped into my throat as I saw him go, leaving me alone with Tao. I concluded that now, if ever, was my opportunity. Tao trusted me--seemed to like me, in fact. No one else in the camp was paying the least attention to us. If only I could, on some pretext, get myself a reasonable distance away from him I would make a run for it.
