Merna then gave us an account of the progress of Martian discovery in regard to aeronautics, from which we gathered that the earlier experiences of the Martians had been somewhat similar to those of our own people. They began with bags of various shapes inflated with gas lighter than air, similar to our balloons, then experimented with aeroplanes of various designs, also bird-like wings, on a very large scale, actuated by electric and other motors. As time went on, however, their atmosphere became thinner and thinner, until at last all such forms of apparatus became nearly, if not quite, useless as a means of artificial flight. After this they made use of numerous vertical screws of a spiral form, which were caused to revolve with extreme rapidity by the aid of electrical machinery; and a few of the vessels thus equipped are still in use. But the discovery of natural forces emanating from the sun and from their own planet soon led to the devising of means for utilising this natural power, and this has practically superseded everything else. Now all their air-ships and many of their machines are actuated by this power, and are under the most perfect control. Air-ships are used for all purposes of passenger traffic and freight carrying. So are vessels on the canals and motor vehicles on the roads; and railways are, therefore, unnecessary. CHAPTER XXVII A FAREWELL BANQUET AND A PAINFUL PARTING The time was nigh at hand when we must think about our arrangements for returning to the earth, and, as it drew nearer and nearer, I became much troubled. I felt that it would be endangering Merna's dear life to take him to England, for our terrestrial microbes would probably prove fatal to a Martian, so it was impossible to suggest it to him; at the same time I felt that I could not again part with my newly-found son, who was now all in all to me. Pondering over the matter, I wondered whether the Martians would allow me to stay with them and end my days on Mars with my beloved son. Just then Soranho came to see me, and we sat awhile talking together. Presently he said, quietly, "Mr. Poynders, you would I know desire to stay here with your son, but are doubtful about mentioning the matter to me. Doubt no longer, my dear sir! We shall be proud and happy to have you with us; and I am quite sure that I am fulfilling the wishes of our people when I now cordially invite you, in their name, to make your home with us!" Thus the Martian intuition had solved my difficulty; and, fervently thanking Soranho, I told him I gratefully accepted his kind invitation and would remain upon Mars, although parting with my two old friends would be a hard task for me.
