There is nothing like the rule of the English in India to be found in history. It has been compared to the dominion which Rome held over so large a portion of the world; but the comparison has not the merit of aptness. The population of the Roman Empire, in the age of the Antonines, has been estimated at 120,000,000, including that of Italy. The population of India is not less than 150,000,000, without counting any portion of the conquering race. Rome was favorably situated for the maintenance of her supremacy, as she had been for the work of conquest. Her dominion lay around the Mediterranean, which Italy pierced, looking to the East and the West, and forming, as it were, a great place of arms, whence to subdue or to overawe the nations. Cicero called the Hellenic states and colonies a fringe on the skirts of Barbarism, and the description applies also to the Roman dominion; for though Gaul and Spain were conquered from sea to sea, and the legions were encamped on the Euphrates, and the valley of the Nile was as submissive to the Cæsars as it had been to the Lagidse, yet the Mediterranean was the basis of Roman power, and a short journey in almost any direction from it would have taken the traveller completely from under the protection of the eagles. Not so is it with British India. From no European country is India so remote as from England. The two regions are separated by the ocean, by seas, by deserts, and by some of the most powerful nations. Their sole means of union are found in the leading cause of their separation. England owes her Indian empire to her empire of the sea. India will be hers just so long, and no longer, as she shall be able to maintain her naval supremacy. Those who predict her downfall in the East, either as a consequence of the natives throwing off her rule, or through a Russian invasion, forget that she entered India from the sea, and that until she shall have been subdued on that element it would be idle to think of dispossessing her of her Oriental supremacy. Were the long-cherished dream of Russia to be realized,--a dream that is said to have troubled the sleep of Peter, and which certainly haunted the mind of Catharine,--and Russian proconsuls ruling on the Ganges, India could no more be to Russia what she has been to England, than the Crimea, had he kept it, could have been to Louis Napoleon what it is to the Czar. The condition of Indian dominion is ocean dominion.
