At Encerro we left four of our fellow-passengers. They were the son and three daughters of the widow who kept the inn. They had been through a full course of studies in one of the Roman Catholic boarding-schools in the United States, and were now returned, having fully mastered the English language--the great desideratum of the Spanish-American people, and one of the sources from which the Catholic schools and colleges in the United States derive their support. What a beautiful spot is Encerro, the country residence of Santa Anna! It may not be as productive as his estate of Manga de Clavo, in the hot country, near Vera Cruz; but it is more salubrious and delightful. In the civil wars he had often made a stand here, and had learned to appreciate the beauty of the spot long before he was rich enough to make the purchase--for the pay received by officers of the highest rank in Mexico, is not sufficient to enable them to accumulate a fortune till far advanced in life. Politicians in Mexico, as in all other countries, are not unwilling to hazard their private fortunes in their political contests, and though the estates of the unsuccessful parties are not confiscated in a revolution, one reason may be that they are not ordinarily of great value. The stage-coach has been forgotten in story-telling while slowly climbing up the pass, but as soon as we had overcome this impediment we started off again upon an unrepaired road, at our former neck-breaking speed, which we kept up until we reached Encerro, where for a little way we had an earthen road. Yet it was only a short breathing before we were upon the rough stones again. We had been gradually passing through different strata of atmosphere in our journey upward, the changes in the character of the vegetation kept pace with the change of the climate. "Whose is that estate inclosed by such an antiquated looking stone wall?" I inquired, of a fellow-traveler. "That belongs to Don Isidoro; and it extends some thirty leagues," was the reply. "You see that ridge of hills. That is its northern boundary. This wall separates it from the estate of Santa Anna. In fact it is surrounded by a continuous and substantial stone-wall, sufficient to keep in cattle. This spot of land sufficiently large for a county, with a soil the richest in the world, and a climate like that of Jalapa, is given up to be a range for thousands of cattle." A TROPICAL FOREST.
