There is little now to be told that all the world does not already know as well as it knows the circumstances of Lord and Lady Redgrave's departure from the Earth, at the beginning of that marvellous voyage, that desperate plunge into the unknown immensities of Space which began so happily, and yet with so many grave misgivings in the hearts of their friends, and which, after passing many perils, the adventurous voyagers finished even more happily than they had begun. As I said at the beginning of this narrative the sole purpose of writing it has been to place before the reading public an account of the adventures experienced by Lord Redgrave and his beautiful Countess from the time of their departure from the Earth to the hour of their return to it. Therefore there is no need to re-tell a tale already told, and one that has been read and re-read a thousand times. Every one who has read his or her newspaper from Chamskatska to Cape Horn, and from Alaska to South Australia, knows how the Commander of the _Astronef_ so nursed the remains which were left to him of the R. Force after overcoming the attraction of the Sun, that he was able to steer an oblique course between the Moon and the Earth, and to counteract what Zaidie called the all too-loving attraction of the Mother Planet, and, after sixty hours of agonising suspense, at last re-entered their native atmosphere. The expenditure of the last few units of the R. Force enabled them to just clear the summits of the Bolivian Andes, to cross the foothills and western slopes of Peru, and finally to let the _Astronef_ drop quietly on to the bosom of the broad Pacific about twenty miles westward of the Port of Mollendo. All this time thousands of anxious eyes had been peering through telescopes every night in quest of the wanderers who must now be returning if ever they were to return, and a reward of ten thousand dollars, offered conjointly by the British and United States Governments for the first authentic tidings of the _Astronef_, was won by a smart young Californian, who was Assistant Astronomer at the Harvard University Observatory at Arequipa. One night when he was on duty watching a lunar occultation, he saw something sweep across the disc of the full moon just as the captain and officers of the _St. Louis_ had seen that same something sweep across the disc of the rising sun. What else could it be if not the _Astronef_? He rang for another assistant to go on with the occultation, and wired down to the coast requesting the British Consul at Mollendo to look out for an arrival from the skies.
