Such being the state of things, the discontented Peruvian colonists not unnaturally turned their attention to Gonzalo Pizarro, the representative of the conqueror under whose banner the country had been won. Gonzalo was at this time at _Charcas_, the modern _Chuquisaca_, and was busily engaged in exploring the silver mines of _Potosí_. He was not discontented at the turn which things had taken, but was sufficiently prudent to provide the means of warfare before rushing into action; and while he did not discourage the malcontents, he was careful not to commit himself. In the latter course he was confirmed by letters from Vaca de Castro, whose prudent measures served at least to lull for a time the troubled waters. The new Viceroy at length arrived. Blasco Nuñez Vela was a handsome cavalier of the years of discretion; but unfortunately he proved wholly unequal to cope with the difficult situation before him. It was not owing to any disapproval of the measures or proceedings of Vaca de Castro that that officer now found himself superseded; but intelligence of events travelled so slowly that the full success of his policy was not at once apparent, and the Government of Spain thought they were acting for the best in sending out as Viceroy a person unconnected with the events that had passed. The Emperor at the same time wrote an autograph letter to the ex-governor, in which he thanked him for his services, and directed him, after having given his successor the benefit of his experience, to return homewards to sit in the royal council. [Sidenote: 1544.] In January 1544 the Viceroy reached the Isthmus. Finding at _Nombre de Dios_ a vessel laden with silver from _Peru_, and which was about to depart for Spain, he lost no time in putting his new edict into execution by laying an embargo on the ship as containing the product of slave labour. He then crossed to _Panamá_, where he caused some three hundred Peruvians to be liberated and sent back to their own country. This proceeding, dictated though it was by a desire to put the new laws into execution without a moment’s delay, was obviously calculated to unsettle the colonial society to the last degree; nor would the Viceroy listen to remonstrances on the subject even from the most experienced persons. All this augured badly for the prospect of peace, and the Viceroy’s progress to the seat of his government only brought matters from worse to worse. On the 4th of March he arrived at _Tumbez_, where his authority was proclaimed, the inhabitants being overawed by the magnificence of his surroundings. Still continuing to exhibit the policy which he had been sent out to initiate, and which with Castilian pride he disdained to veil, he here liberated a number of Peruvian slaves. From _Tumbez_ he proceeded by land towards the south, causing his baggage to be carried by mules when practicable, or, if the services of Peruvians were necessary for this purpose, he took care that they should be duly paid.
