"I wonder what they think he is doing in there," I said, the third day after our return, as we sat on a balcony of the floating tower, with our feet nonchalantly elevated on a railing, and our eyes drinking in the magnificent prospect of the vast city, as brilliant in variegated colors as a flower garden, while a soft breeze, that gently swayed the gigantic gossamer, soothed us like a perfumed fan.

"Worshipping the sun god, I reckon," laughed Jack. "But, see here, Peter, what do you make of this religion of theirs, anyway?"

"I don't know what to make of it," I replied. "But if the sun really does appear to them once in a lifetime, or so, as Edmund thinks, it seems to me natural enough that they should worship it. We have done more surprising things of the kind on the earth."

"Not civilized people like these."

"Oh, yes. The Egyptians were civilized, and the Romans, and they worshipped all sorts of strange things that struck their fancy. And what can you say to the Greeks—they were civilized enough, and look what a collection of gods they had."

"But the wise heads among them didn't really believe in their gods."

"I'm not sure of that; at any rate they had to pretend that they believed. No doubt there were some who secretly scoffed at the popular belief, and it may be the same here. I shouldn't wonder if Ingra were one of the scoffers. Edmund has a great opinion of his intelligence, and if he really doesn't believe in the thing, he is all the more dangerous for us, because you know that now we are depending a good deal on their superstition for our safety."

"But Ala is very intelligent, a regular wonder, I should think, from what
Edmund says; and yet she accepts their superstition as gospel."

"Lucky for us that she does believe," I said. "But there's some great mystery behind all this; Edmund has convinced me of that. We don't begin to understand it yet, and there are moments when I think that Edmund is afraid of the whole thing. He seems dimly to foresee some catastrophe connected with it, though what it may be I cannot imagine, and I think he doesn't know himself."

Henry listened to our conversation without proffering a remark—quite the regular thing with him—and at this point Jack, yielding to the overpowering sense of well-being, and the soothing influence of the delicious air and delightful view, closed his eyes for a nap.
