“The ruins are generally found on high ground, and are composed of from two to several hundred rooms, averaging about eight by ten feet, and six to eight feet in height. In some cases the buildings have been two stories high. There has been a side entrance to all of these rooms, but these openings, from some cause, have been carefully walled up. [Illustration: SCENE ON THE GREAT AMERICAN DESERT.] “These people were larger than those of to-day, some of them being fully eight feet high. I am led to believe their average height was not less than seven feet. They buried their dead in the ground floors of their rooms, with the heads towards the east, and, as a rule, their pottery, trinkets and personal ornaments with them. In excavating these ruins, one is constantly impressed with one paramount wonder—their great age. Huge pine trees, three and four feet in diameter and 100 feet high, flourish upon the walls and in the rooms of these habitations of forgotten man. The infilling of drift and the increase of surface, caused by vegetable growth and decay, is very slow, and has been estimated by some geologists to average about one foot in eighty years. Admitting this to be near the truth, our surprise knows no bounds when, on sinking directly under these giant trees, we pass through from six to ten feet of vegetable mold, then encounter from one to three feet of clean-washed sand and gravel, then a solid earthen floor covered with ashes, charcoal, bones and fragments of broken pottery. Yet still below this are the skeletons of human beings, surrounded by their pottery, weapons and ornaments of stone, bone and copper. My own opinion is that these people were either Aztecs or Toltecs. They were sun-worshipers and well advanced in carving, painting, building, weaving and agriculture. They flourished many centuries in Colorado, Arizona, New Mexico, Mexico, Central and South America, and were exterminated either by famine, flood, disease or volcanic action at least 1,000 years ago. “In the eastern part of this (Socorro) county are the ruins of an immense city known as the Grande Quivero, covering two by two and one- half miles square. Its walls are, in some places, eight feet thick, forty feet high, and 700 feet long. A great aqueduct carried water to the city, but to-day there is no water within forty miles of this ancient wonder. It stands silent and alone in the sunlight and moonlight, and where once the love, industry and skill of an unknown race made thousands of beautiful and happy homes, the coyote, bat and snake now hold sway. When and by whom it was built was a mystery to the Mexican people more than 300 years ago.” ------------------------------------------------------------------------ [Illustration:
