These people all bore shields, which, strange to say, seemed to be of glass, for they were perfectly transparent; and by way of arms each had an odd-looking twisted pole or spear, which looked like two rods of polished steel entwined together. At the top was a flat, spear-shaped piece of light-coloured silvery metal, with three points or prongs instead of one. Stuck into the belt of each, as people might stick pistols, were two or three smaller articles. One of them looked like a hunting-knife or dagger; but regarding the others, Gerald could form no sort of idea as to their use or meaning, and could only vaguely guess that they were probably weapons of a kind unknown to dwellers upon the Earth. One of these men, who appeared to be their officer, motioned to Gerald to follow him, and turned and led the way. Outside there were half a dozen more men in waiting, all similarly dressed. The officer signed to Gerald to follow a couple of these, while he himself, with the others, fell in behind; and thus they all marched onwards in double file, like a squad of soldiers. They traversed many passages and galleries, where Gerald saw plenty to attract attention and excite wonder. They passed also people standing about in small groups, and these looked as curiously at the prisoner—for such he felt himself to be—as did he at them. There was, however, no time or opportunity for more than a fleeting glance; he was hurried onwards, till suddenly there came a great surprise. Passing through an entrance, which in massiveness and design seemed to the wondering captive more like the gateway to a medieval castle than a doorway one might expect to find in such a place, they emerged into a large open space. Gerald looked round, and as he did so, a gasp of astonishment escaped him. He found himself in what had all the appearance of a spacious, lofty hall, with a domed roof, around which glittered numerous lights. But his attention was at once drawn to the other end of the room. Here was a dais, and upon it were several persons. They were seated, for the most part, on handsomely carved and upholstered armchairs; but two of the latter were higher and larger than the rest, so that they partook rather of the character of thrones, and of these one again was larger and more important-looking than the other. Very strange affairs were these two high seats, ornamented as they were with carvings representing heads of the queerest-looking creatures that can well be imagined. The high backs curled over above, fashioned again in the shapes of heads of most horrible, fantastic monsters; smaller heads, vying with them in frightful ugliness, formed the ends of the arms.
