"They built temples—mounds of clay faced with brick, surmounted by great towers where the priests dwelt. It was at the summits of these mounds, on a sacrificial stone, before all the people who could get in view, that the victims of their religious frenzy were slain.

"Then Cortes came, in fifteen hundred and something, and the deluge of blood began. If you have read up on the subject at all, you doubtless know how merciless the Spaniards were in their attitude toward the Aztecs. They killed them by thousands, in open battle and by treacherous means, and they tortured Aztec priests to force them to reveal the places where the vessels of gold used in worship were hidden.

"It is easy to see where the modern Mexican gets his ideas of amusement, as shown in the bull fight. The Aztec-Spanish blood is still in his veins. Of course there are cultured and refined Mexicans, but the great mass of the people are pretty primitive. Outside the cities, in many instances, old tribal relations continue, and the people are unsettled in habitation as well as in spirit, selfish and cruel, too.

"One revolution after another—brought about by unscrupulous leaders in the hope of personal gain—has devastated the country. It seems easy to stir up a revolution in Mexico, for the people are volcanic in temperament, like the earth under their feet, and their eruptions do not always follow usual lines, either, but break out in unexpected places and for unheard of reasons—just as the volcanoes refuse to follow the central mountain chains, but break out in undreamed of localities."

"It requires a strong hand to rule such a people," Jimmie mused. "I guess Diaz has troubles of his own."

"There is no doubt of it," the drummer continued. "In future years Mexico will become one of the garden spots of the world. It is clear why one people after another selected the Valley of Mexico for their abiding place. But blood will tell for evil as well as for good, and the bad strain here must be thinned down. The hills are rich in minerals, and the valleys are fertile, and all the land needs is a race of steady, patient workers—fewer bull fights and less pulque and more days' work."

As the drummer ceased speaking, Jimmie laid a warning hand on his shoulder and bent his head forward in a listening attitude.

"Listen!" he said. "There are men talking just over that slope."
