As we came to larger towns we could see armed horsemen riding at a 2:09 speed, leaving a cloud of dust in their wake, to the stations. When the train stopped they formed in a decorous line before it, and so remained until the train started again on its journey. I learned that they were a government guard. They do this so, if there is any trouble on the train or any raised at the station during their stop, they could quell it. Hucksters and beggars constitute most of the crowd that welcomes the train. From the former we bought flowers, native fruit, eggs, goat milk, and strange Mexican food. The pear cacti, which is nursed in greenhouses in the States, grows wild on the plains to a height of twenty feet, and its great green lobes, or leaves, covered thickly with thorns, are frequently three feet in diameter. Some kinds bear a blood-red fruit, and others yellow. When gathered they are in a thorny shell. The Mexican Indians gather them and peel them and sell them to travelers for six cents a dozen. It is called "tuna," and is considered very healthy. It has a very cool and pleasing taste. From this century-plant, or cacti, the Mexicans make their beer, which they call _pulque_ (pronounced polke). It is also used by the natives to fence in their mud houses, and forms a most picturesque and impassable surrounding. The Indians seem cleanly enough, despite all that's been said to the contrary. Along the gutters by the railroad, they could be seen washing their few bits of wearing apparel, and bathing. Many of their homes are but holes in the ground, with a straw roof. The smoke creeps out from the doorway all day, and at night the family sleep in the ashes. They seldom lie down, but sleep sitting up like a tailor, strange to say, but they never nod nor fall over. The whirlwinds, or sand spouts, form very pretty pictures on the barren plain. They run to the height of one thousand feet, and travel along the road at a 2:04 gait, going up the mountain side as majestic as a queen. But then their race is run, for the moment they begin to descend their spell is broken, and they fall to earth again to become only common sand, and be trod by the bare, brown feet of the Indian, and the dainty hoofs of the burro. Some one told me that when a man sees a sand spout advancing, and he does not want to be cornered by it, he shoots into it and it immediately falls. I can't say how true it is, but it seems very probable. We had not many passengers, but what we had, excepting my mother and myself, were all men. They all carried lunch-baskets. Among them was one young Mexican gentleman who had spent several years in Europe, where he had studied the English language. He was very attentive to us, and taught me a good deal of Spanish. He had been away long enough to learn that the Mexicans had very strange ideas, and he quite enjoyed telling incidents about them.
