Stronghand by Gustave Aimard

While these events were taking place at the Hacienda del Toro, others of an even more important nature were being carried out at the Real de Minas. Kidd the adventurer, had scarce left Don Rufino Contreras, after the interesting conversations we have recorded, ere the senator made his preparations for departure, and at once set out for the Real de Minas, though careful to be accompanied by a respectable escort, which protected him from the insults of marauders. At eight a.m. of the following day the senator entered the pueblo, and his first business was to present himself to the town commandant, Don Marcos de Niza. The captain not only received him coldly, but with a certain amount of constraint. This did not escape the senator's quick eye, but he was not at all affected by it.

"My dear captain," he said, after the usual compliments, "I am pleased at having been selected by the Presidential Government as its delegate to the military authorities of the State of Sonora for two reasons, apart from the honour I shall acquire by accomplishing this confidential duty."
