The sentry walked back across the bridge and knocked at the gate. After a lengthened parley a sergeant stepped out through a wicket, and requested Don Carlos to come forward and step inside. Don Carlos walked across the bridge, passed the wicket and found himself in the midst of an armed party of the Patricios, one of whom held up a lantern to his face. "Ah! it is you, Don Carlos," said a young officer, stepping forward. "Excuse the delay, but after the affair of to-day no precaution is too much." "You do perfectly right, Valentin," replied Don Carlos; then passing his arm over the shoulder of the young officer he whispered some few words in his ear. Five minutes later Don Carlos was seated in the private apartment of the Viceroy, and with him held earnest converse for nearly an hour. "Then your Excellency entirely rejects my proposal," said Evaña. "I do," replied the Viceroy. "I hold my authority from the Court of Spain, and will suffer no innovations without consulting the supreme authorities, whoever they may happen to be." "Think well what you do, Don Santiago. Such an opportunity as the present may never offer itself to you again. The people have to-day for the third time shown their power. Twice have they repulsed invasions of the English, to-day they have humbled the arrogance of the Spaniards. Put yourself at the head of this new power which has risen up in America, and a new career of greatness and of glory will open up before you. Attempt to arrest the progress of the people, and they themselves, who to-day have offered their lives for you, will crush you to the dust." "You threaten me," exclaimed the Viceroy. "I do not threaten you, I merely warn you. If I stand forth myself and proclaim the liberty of the people they will rise as one man to demand their rights. Who is there that shall say them nay?" "The people would not listen to you," replied the Viceroy. "I wish to avoid bloodshed and contention, therefore I ask you, who hold the power in your hands, to put yourself at the head of the people. Under your leadership there will be no contention, no bloodshed." "Know you not that this is treason which you propose to me? What hinders me from ordering your immediate arrest as a conspirator against Spain?" "Do it," said Evaña, rising. "Call in your guards, order them to arrest me. Doubtless they will obey you, but to-morrow's sun will see the last day of your authority in Buenos Aires. Shoot me if you like. I should die joyfully, for I know that my blood would purchase the liberty of my own people." "No. You have come here unarmed and alone. I respect the trust you have placed in me, but give some attention to my words. I have long had my eye upon you as a man of dangerous ideas--ideas which you have now disclosed to me. Look well what you do, for whilst I hold authority as Viceroy I will maintain that authority intact, and will punish any revolutionary attempt with the extremest rigour of the law."
