to each plough. The yoke is fastened to the horns of the oxen, and to the centre of the yoke a pole is attached. At the other end of this pole is the plough itself, which consists of a wooden stake with an iron point and a handle. The driver holds the handle in one hand and his goad in the other (a long reed with an iron point), and so they toil along, making a long scratch as they go. A man follows the plough, and drops in single grains of Indian corn, about three feet apart. The furrows are three feet from one another, so that each stalk occupies some nine square feet of ground. When the plants are growing up they dig between them, and heap up round each stalk a little mound of earth.
We passed many little houses consisting of one square room, built of mud-bricks, with mud-mortar stuck full of little stones; without windows, but generally possessing the luxury of a chimney, with a couple of bricks forming an arch over it to keep out the rain. Glimpses of men smoking cigarettes at the doors, half-naked brown children rolling in the dirt, and women on their knees inside, hard at work grinding the corn for those eternal tortillas.
At San Juan de Dios Mr. Christy climbed to the top of the Diligence, behind the conductor, who sat with a large black leather bag full of stones on the footboard before him. Whenever one of the nine mules showed a disposition to shirk his work, a heavy stone came flying at him, always hitting him in a tender place, for long practice had made the conductor almost as good a shot as the goat-herds in the mountains, who are said to be able to hit their goats on whichever horn they please, and so to steer them straight when they seem inclined to stray. But our conductor simply threw the stones, whereas the goat-herd uses the aloe-fibre honda, or sling, that one sees hanging by dozens in the Mexican shops.
We pass near Churubusco, and along the line by which the American army reached Mexico. The field of lava which they crossed is close at our
