The loss of the _Sirius_ did not prove so disastrous, after all. There are cunning artificers and skilful engineers in many parts of Gathma, able to work out the Doctor's designs with even greater exactness than the men of Earth. Another point, vastly favouring the Doctor's plans, was the wonderful development of electrical science, a branch of knowledge only in its infancy on Earth. How this marvellous force has become utterly subservient to human will, in Gathma, has been dimly hinted at in many parts of our narrative; but Doctor Hermann, whether wisely or not, has deemed it best to say little until we return to our native Earth again. Already a new carriage is being constructed on the same plan as the _Sirius_, but embodying many improvements, some of them the result of our experience on the way hither, others the suggestions of cleverer engineers than we. Several years must of necessity elapse before the grand experiment will be tried, as the Doctor is anxious to acquire as much information as possible before returning. Already his five-and-sixty years of life begin to press heavily upon him, and he feels that if he once gets back to Earth, he will not be equal to the hardships and the risks of another journey here. Younger men, we doubt not, will be eager and willing to make this awful plunge across the sky, as soon as the tidings of our glorious success reach Earth, and they are put in possession of the secrets that will bear them triumphantly here. And now, as these manuscripts already exceed in bulk and weight the measure that has been allowed them by Doctor Hermann in his calculations when making the machine that is to attempt to bear them to Earth, but few words are we permitted to say. The result of our enterprise has been one unqualified triumph. Many perils, many hardships, many dangers have been encountered and have been overcome, as the reader of this stirring story, which is but a fragment of what we have to tell, already knows. We have piles upon piles of manuscripts dealing with scientific, social, and religious subjects; folios upon folios of sketches portraying objects upon which the eyes of earthly man have never rested, and of which he has not the faintest conception. A few of these we send with this. Not only are we enriched with the knowledge we have gained for ourselves, but we are heavy-laden with the results of unnumbered centuries of scientific research, conducted by accomplished philosophers here. Their discoveries in the science of astronomy are marvellous, and make us look upon our own attainments in this direction with supreme pity. The conditions of life upon this planet are exceptionally favourable to the advancement of this science, the grand age of the astronomers permitting them to perfect experiments and calculations, and observe phenomena which on our own world have to be left to posterity.
