“If we found the like of it around London it would not be natural, but it would be very pleasant,” put in Joe. “Why is it that such savage countries get all these fine things?” “And who knows,” said the doctor, “that this country may not, one day, become the centre of civilization? The races of the future may repair hither, when Europe shall have become exhausted in the effort to feed her inhabitants.” “Do you think so, really?” asked Kennedy. “Undoubtedly, my dear Dick. Just note the progress of events: consider the migrations of races, and you will arrive at the same conclusion assuredly. Asia was the first nurse of the world, was she not? For about four thousand years she travailed, she grew pregnant, she produced, and then, when stones began to cover the soil where the golden harvests sung by Homer had flourished, her children abandoned her exhausted and barren bosom. You next see them precipitating themselves upon young and vigorous Europe, which has nourished them for the last two thousand years. But already her fertility is beginning to die out; her productive powers are diminishing every day. Those new diseases that annually attack the products of the soil, those defective crops, those insufficient resources, are all signs of a vitality that is rapidly wearing out and of an approaching exhaustion. Thus, we already see the millions rushing to the luxuriant bosom of America, as a source of help, not inexhaustible indeed, but not yet exhausted. In its turn, that new continent will grow old; its virgin forests will fall before the axe of industry, and its soil will become weak through having too fully produced what had been demanded of it. Where two harvests bloomed every year, hardly one will be gathered from a soil completely drained of its strength. Then, Africa will be there to offer to new races the treasures that for centuries have been accumulating in her breast. Those climates now so fatal to strangers will be purified by cultivation and by drainage of the soil, and those scattered water supplies will be gathered into one common bed to form an artery of navigation. Then this country over which we are now passing, more fertile, richer, and fuller of vitality than the rest, will become some grand realm where more astonishing discoveries than steam and electricity will be brought to light.” “Ah! sir,” said Joe, “I’d like to see all that.” “You got up too early in the morning, my boy!” “Besides,” said Kennedy, “that may prove to be a very dull period when industry will swallow up every thing for its own profit. By dint of inventing machinery, men will end in being eaten up by it! I have always fancied that the end of the earth will be when some enormous boiler, heated to three thousand millions of atmospheric pressure, shall explode and blow up our Globe!” “And I add that the Americans,” said Joe, “will not have been the last to work at the machine!”
