Once again the willing horses climbed the hill, and reaching the summit we inspected the waterworks which have so faithfully supplied the city for years. A weather-beaten frame house hid the well or spring that has given such a generous supply. A wooden wheel as large as the house itself, moved slowly, as if age and rheumatism had stiffened its joints. The water flowed gently through an open trench into another building, whence it rushed, white, foaming and sparkling, into the ground, leaving only high brick air-pipes to mark its course to the aqueduct. By the side of the trench a woman was doing her washing, and two little lads, with poles across their shoulders and buckets suspended from either end, were carrying water to the houses down in the valley. An old cow with curly horns gazed at us in astonishment as we invaded her private meadow to get a view of a paper mill, which is built in the shape of an old English castle, down in a deep ravine in a nest of lovely green trees. The old cow had evidently come to the conclusion, after deliberate reasoning, that we were intruding, and she charged our horses in a first-class "toro" style. There were no _capeadores_ to attract her attention, no _bourladeras_ for us to hide behind, so we thought it best to fly, which we did with a Maud S speed. I did not mention I had lost my hat in the retreat until we were over the trench, and one of the young men gallantly started to recover it, against the protestations of the entire crowd. We expected to see him killed, but the cow stood watching him as he dismounted for the feminine headgear, gesticulating with head and tail and beating the earth with her fore legs. Remounting, he saluted her, then putting spurs to his horse he cleared the ditch, leaving the baffled and angry cow on the other side. La Castaneda, the great pleasure-garden of the Mexicans, was next visited. Beautiful flowers, shrubbery and marble statues grace the well-kept resort. Neat little benches, cunning little vine-draped nooks, sprinkling-fountains, secluded dancing-stands, deep bathing-basins, are a few of the many attractions. Shaded walks and twisting stairways would always bring us to some new beauty. Music and dancing are always held here every afternoon, and although it was nearly noon they had not even so much as a cracker in the house. In Mexico nothing in the line of edibles is kept in the house overnight.
