No two characters seem more inconsistent than those of trader and sovereign. If the trading spirit of the English East India Company renders them very bad sovereigns, the spirit of sovereignty seems to have rendered them equally bad traders. While they were traders only they managed their trade successfully, and were able to pay from their profits a moderate dividend to the proprietors of their stock. Since they became sovereigns, with a revenue which,
