"Well, I hardly know," he replied doubtfully. "It is rather out of my line, and after my experience with Mars the other night, I am not inclined to dogmatise. At all events, I should like to see and try the machine before giving an opinion." "I will arrange for that with the inventor." "Possibly I can find out something about him from my American friends--if he is genuine. What's his name again?" "Carmichael--Nasmyth Carmichael." "Nasmyth Carmichael," repeated Gazen, musingly. "It seems to me I've heard the name somewhere. Yes, now I recollect. When I was a student at Cambridge, I remember reading a textbook on physics by Professor Nasmyth Carmichael, an American, and a capital book it was--beautifully simple, clear, and profound like Nature herself. Professors, as a rule, and especially professors of science, are not the best writers in the world. Pity they can't teach the economy of energy without wasting that of their readers. Carmichael's book was not a dead system of mathematics and figures, but rather a living tale, with illustrations drawn from every part of the world. I got far more help from it than the prescribed treatises, and the best of that was a liking for the subject. I believe I should have been plucked without it." "The very man, no doubt." "He was remarkably sane when he wrote that book, whatever he is now. As to his character, that is another question. Given a work of science, to find the character of the author. Problem." "I shall proceed cautiously in the affair. Before I commit myself, I must be satisfied by inspection and trial that there is neither trickery nor self-delusion on his part. We can make some trial trips, and gain experience before we attempt to leave the world." "If you take my advice you will keep to the earth altogether." "Surely, if we can ascend into the higher regions of the atmosphere, we can traverse empty space. You would have me stop within sight of the goal. The end of travel is to reach the other planets." "Why not say the fixed stars when you are about it?" "That's impossible." "On the contrary, with a vessel large enough to contain the necessaries of life, a select party of ladies and gentlemen might start for the Milky Way, and if all went right, their descendants would arrive there in the course of a few million years." "Rather a long journey, I'm afraid." "What would you have? A million years quotha! nay, not so much. It depends on the speed and the direction taken. If they were able to cover, say, the distance from Liverpool to New York in a tenth of a second, they would get to Alpha in the constellation Centaur, perhaps the nearest of the fixed stars, in twenty or thirty years--a mere bagatelle. But why should we stop there?" went on Gazen. "Why should we not build large vessels for the navigation of the ether--artificial planets in fact--and go cruising about in space, from universe to universe, on a celestial Cook's excursion--" "We are doing that now, I believe."
