At La Villa de Leon, a town celebrated for robbers and murderers, Mr. Ruxton met with an adventure. About nine o’clock in the evening he was returning from the plaza, which with its great lighted fires, the stalls of the market-people, the strange garb of the peasantry, and the snow-white sarapos, or cloaks, of the idlers of the town, presented a stirring aspect, when, striking into a dark and narrow street, a group of vagabonds, at the door of a pulque shop, detected that he was a stranger, and, mistaking his nationality, yelled at him: “Let’s kill him, the Texan!” Having no weapon but a bowie-knife, and not desiring an encounter with such overwhelming numbers, he turned off into another street; but the rascals followed him, renewing their wild cries. Happily, a dark doorway invited him to seek its shelter, and while crouching in its obscurity, he could see them rush by, knives in hand. When he thought they had all passed, he stepped forth, to find himself confronted by three wretches who brought up the rear, and who, brandishing their knives and rushing headlong at him, cried, “Here he is, here he is; kill him!” As the foremost rushed at him with uplifted blade, he swiftly stepped aside, and at the same moment thrust at him with his bowie. The robber fell on his knees with a cry of “Me ha matado!” (“He has killed me!”), and fell on his face. One of his companions hastened to his assistance; the other dashed upon Mr. Ruxton, but, confused by his calm attitude of preparation, fell back a few paces, and finally slunk away. Mr. Ruxton returned at once to his quarters, ordered out the horses, and in a few minutes was on his road. By way of Aguas Calientes, a very pretty town, and Zacatecas, a populous mining town, he proceeded towards the Hacienda (or farm) of San Nicolas, with the view of traversing that singular volcanic region, the _Mal Pais_. Down to a comparatively recent period, it would seem to have been the theatre of plutonic phenomena of an extraordinary character. The convexity of the district enables the traveller to judge very readily of the extent of the convulsion, which has spread to a distance of twelve or fourteen miles from the central crater. The said crater measures about fifteen hundred feet in circumference, and its sides are covered with dwarf oaks, mezquito, and cocoa trees, which find a rich nourishment in the chinks and crevices of the lava. At the bottom stagnate the green and slimy waters of a small lake, which is fringed with rank shrubs and cacti, growing among huge blocks of lava and scoriæ. Not a breath of air disturbs its inky surface, save when a huge water-snake undulates across it, or a duck and her progeny swim out from their covert among the bushes.
