But where was the Brick Dome of the MOON? "Good Heavens! has it fallen on them all?" cried I. Haliburton lashed the beast till he fairly ran down that steep hill. We turned a little point, and came out in front of the centring. There was no MOON there! An empty amphitheatre, with not a brick nor a splinter within! We were speechless. We left the cutter. We ran up the stairways to the terrace. We ran by the familiar paths into the centring. We came out upon the ways, which we had never seen before. These told the story too well! The ground and crushed surface of the timbers, scorched by the rapidity with which the MOON had slid down, told that they had done the duty for which they were built. It was too clear that in some wild rush of the waters the ground had yielded a trifle. We could not find that the foundations had sunk more than six inches, but that was enough. In that fatal six inches' decline of the centring, the MOON had been launched upon the ways just as George had intended that it should be when he was ready. But it had slid, not rolled, down upon these angry fly-wheels, and in an instant, with all our friends, it had been hurled into the sky! "They have gone up!" said Haliburton; "She has gone up!" said I;--both in one breath. And with a common instinct, we looked up into the blue. But of course she was not there. -------- Not a shred of letter or any other tidings could we find in any of the shanties. It was indeed six weeks since George and Fanny and their children had moved into Annie and Diamond,--two unoccupied cells of the MOON,--so much more comfortable had the cells proved than the cabins, for winter life. Returning to No. 7, we found there many of the laborers, who were astonished at what we told them. They had been paid off on the 30th, and told to come up again on the 15th of April, to see the launch. One of them, a man named Rob Shea, told me that George kept his cousin Peter to help him move back into his house the beginning of the next week. And that was the last I knew of any of them for more than a year. At first I expected, each hour, to hear that they had fallen somewhere. But time passed by, and of such a fall, where man knows the world's surface, there was no tale. I answered, as best I could, the letters of their friends; by saying I did not know where they were, and had not heard from them. My real thought was, that if this fatal MOON did indeed pass our atmosphere, all in it must have been burned to death in the transit. But this I whispered to no one save to Polly and Annie and Haliburton. In this terrible doubt I remained, till I noticed one day in the "Astronomical Record" the memorandum, which you perhaps remember, of the observation, by Dr. Zitta, of a new asteroid, with an enormous movement in declination.
