Judging that it was best to leave what I had said to produce its effect, I stopped for a minute, and then continued,--"Well, your Excellency, I need not speak further about Senor Ricardo Duffield. I have now to plead for another person, who, although not an Englishman, belongs to all civilised countries in the world, and all will equally stigmatise those who injure him; I allude to the learned Dr Cazalla. I beg that he may be allowed to accompany me to my own country, where he can prosecute his scientific studies without molestation." The general's brow grew darker than ever. "He is one of the pests of this country. He taught the rebels how to make gunpowder and arms, to be used against their rightful sovereign. He shall die, even although the whole British army, with your Lord Wellesley at their head, were to endeavour to rescue him." "That's an ungrateful remark, your Excellency, considering the service he has rendered Spain," observed Mr Laffan; "but it's just what may be expected." "Go out of my presence--this instant!" exclaimed the general, irritated by this imprudent remark. "The prisoners shall die; and let me tell you that your errand is bootless." I felt, indeed, that such was the case. In fact, I heard the general, turning to the officer who acted as his chief of police, direct him to keep an eye upon us. His suspicions had, I saw, been aroused. We did not consider it necessary to pay any special mark of respect as we took our leave. The general was talking to the officers at his side, scarcely deigning to notice us. With heads erect, and as calm countenances as we could command, we passed through the crowd in the ante-room, and made our way into the street. We then hurried back to Don Jose's, to tell him how fruitless had been our visit to the viceroy. "I was afraid so," observed our host. "If Murillo has made up his mind, no power on earth can turn him from his purpose." I had not forgotten Antonio, and had formed a plan to try and rescue Mr Duffield and Dr Cazalla, should other means fail. As Antonio had not already betrayed me, I had great hopes that I could rely on his assistance. Always accompanied by Mr Laffan, I went about endeavouring to discover him. I at length ascertained that he belonged to the guard stationed at the prison. In all probability, then, he would at times have charge of the prisoners inside; and if so, he might be able to aid in their escape. Before long we fell in with him off duty, and near the prison itself. It was late in the evening, but there was sufficient light for us to recognise each other. I made a sign, and he followed us to a dark spot under the prison walls. "You know me, Antonio?" I asked. "Ah yes, senor, the moment I saw you, while we were on the march here. I joined the Godos as the only means of saving my life--having obtained the uniform of a corporal who had been killed. My intention, however, was to desert on the first opportunity."
