But this great re-emigration produced evils of no common magnitude in Brazil. It is computed that fifty millions of crusadoes, at least, were carried out of the country by the Portuguese returning to Lisbon. A great proportion of specie had been taken up in exchange for government bills on the treasuries of Bahia, Pernambuco, and Maranham. But these provinces, from the revolution in February, had disclaimed the superiority of the government at Rio, and had owned no other than that of the Cortes at Lisbon, and above all the ministry well knew, even at the time of granting the bills, that they had refused to remit any portion of the revenue to Rio. Hence arose commercial distress of every description, and as long-standing government debts had been also paid by these bills which were all dishonoured, the evil spread far and wide, not only among the natives but the foreign merchants. It was of little avail that the Prince acknowledged the debts[36]; the treasury was left so poor, that he was obliged to delay or modify the increase of military pay promised on the King's departure, a circumstance that occasioned much disquiet in several provinces. The funds for carrying on several branches of industry, and several works of public utility were destroyed by this great and sudden drain; and thereby much that had been begun after the arrival of the court, and which it was hoped would have been of the greatest benefit to the country, was stopped. Colonies that had been invited to settle with the most liberal promises perished for want of the necessary support in the beginning of their career, and the wonder is, not that disturbances in various quarters took place after the departure of the King, but that they were not of a more fierce and fatal tendency. [Note 36: It was of little avail at the time. But as soon as it was possible, his royal highness's government began payments by instalments, which are still going on, notwithstanding the total change of government. This is highly honourable.] The Prince who remained at the head of the government was deservedly popular among the Brazilians. His first care was to examine into and redress causes of grievances; particularly those arising from arbitrary imprisonment and vexatious methods of collecting taxes. The great duties on salt conveyed into the interior, were remitted. Something was done towards improving the condition of the barracks, hospitals, and schools. Books were allowed to be imported duty free, and every thing that could be effected under the circumstances, was done by the Prince for the advantage of the people, and to preserve or promote public tranquillity.
