It has been mentioned above that the interests of Portugal were at this time watched over at the Hague by a most astute diplomatist. The professional morality of European diplomacy has become considerably stricter in the course of late years than it was in the year of which we write, namely, 1646. Francisco de Sousa must be judged, therefore, as to his diplomatic conduct, by the ethics of his own age rather than by those of the present time. He had a most difficult part to play; and, being a thorough patriot as well as doubtless a devout Catholic, he held that the interests of his country, if not those of his faith, justified him in any amount of dissimulation, in order to secure them. His judgment both as to the importance of the Portuguese settlements in Northern _Brazil_ to his country and as to the practicability of recovering them, was sound, as was proved by the event; but, as has been said, there were imperious reasons to make the court of Lisbon dread an open rupture with Holland. Under the circumstances the ambassador had the courage to take upon himself the entire responsibility of negotiating with the Dutch, leaving it to his master to disavow his proceedings should it prove necessary for the public well-being so to do. He was well aware that he was fully trusted; but he could not foresee all the possibilities of the future. The Dutch statesmen, although they were slow at arriving at conclusions, could not but perceive that the Portuguese diplomatist had been merely seeking to gain time. They therefore called upon him to give a categorical statement of the intentions of his government with reference to _Brazil_. He replied in a note, in which he asserted that he had instructions to treat with them respecting the affairs of _Pernambuco_; and he requested that a conference might take place in time to save them the expense of fitting out an unnecessary armament. The Dutch Government, perceiving that he was only renewing his former practices, declined his proposal; whereupon De Sousa, being hard pressed, offered to communicate the instructions on which he was to act. This was a bold step; for it required the exercise of some creative genius on his part. He had, however, with him some blank despatches from his Government already signed, and one of these he filled up so as to suit the moment. The result was that the Dutch, being deceived, suspended their naval preparations.
