On one foot log we discovered what appeared to be walking leaves, as the green leaves glided along, moved by an unseen power. Investigation proved them to be an army of ants, each one carrying a leaf on its back which looked like a little sail. On the edge of the bank, half in the water, half out, lay a branch of willow. These little things climbed it, risking life and limb, and, cutting off a leaf, hoisted it on their backs and marched easily a quarter of a mile to their home. They had a path of road about five inches wide made along the grass all the distance. The street cleaners must be faithful, as it was as clean as could be, shaded on either side by the grass, without one blade in their way. They crossed the foot log and disappeared in a hole at the other end. We wondered what they were making inside with those many leaves. They were so interesting at their work that it was with reluctance we left them. Boarding our train, with much regret, we were soon lost to sight of the Valley of Orizaba and were once more on our way to a new and strange city. CHAPTER XXII. THE WONDERS OF PUEBLA. If the innocent-looking tourists believed all that is told them here they would conclude that every spot and town of interest had been built by the Virgin and the angels. One night many, many years ago, so the story runs, one good priest, who was known by the name of Motolinia, which means humble, mean, lowly, had a vision. A number of sweet angels--all of the feminine gender--draped with some soft, thin material, with long, silky black hair that fell to their feet in heavy folds, and sparkling black eyes, took the good father in their arms and bore him through the air to a spot not far distant from his little hut. After setting up a stone cross, which, at their petition, apparently descended from the skies, they helped him to build churches, houses, factories, and bull-rings (perhaps). It took seven days and the same number of nights to build the world, but the city of Puebla was built in a few moments. Probably the fatigue from work or the unusual company made the good man tired and drowsy, so he fell asleep, as sweetly as a babe, fanned by the wings of the heavenly beings around him. Waking from a most refreshing nap, in which he had dreamed of honey, golden crowns, feathered wings, and regiments of beautiful creatures, he found to his surprise that he was once again in his little bed, with no angels in sight. "They have gone out to complete the work, while I, lazy creature, slept," thought the good father, and going to the window he flung it open. He saw the green plain undisturbed.
