This Canyon was the best in the entire PajaritoÑthe most coveted of all habitable places. The water supply was apparently constant and the valley was broad and open at the lower end, most suitable for agriculture. The floor was densely covered with growths of scrub oak, pifion and pine. This was all that primitive groups needed for successful living. And so we find that some of these wandering Indians from a world a hundred miles to the west, which was to become a thing of the past, penetrated the Valley of the Frijoles over eight hundred years ago. But Frijoles Canyon was not the only place occupied. There were other canyons nearby. Ther

m for all. But was there enough water in these other canyons? Indian families cut their crude shelters deep enough for occup^ation by several individuDACSals. Caves were uncomfortable, but certainly better than no shelter at all. This was a strange sort of stone which nature had provided. It was very poor to build with, thought the Indian. It was soft and bulky. But years of living would eventually solve the problem. Why worry about it! In time necessity would produce some means of shelter more

satisfactory. Later on, more people moved into the area. These people occupied adjacent canyons and mesas as well as Frijoles. During many years population increased and the dwellers on the Pajarito became settled in their locality. There is no way of telling how many Indians lived in the Valley of the Frijoles during very early timesÑclose to water and well protected. Indians could sit at the openings of their cave homes above the talus slope and see for great distances up and down the Canyon. And it was safe. No jealous enem^ lurking above could roll a boulder down on them. Their cave was their protection. B

ut caves were

notadequate as homes. Fires could not be built inside without smoking out TYUONYI its occupants. Something better had to replace them. This new soft rock certainly was not suitable for building walls or at least these simple valley folk diLOXd not know how to use it. Crude mud huts

were erected at the base of the cliff at the same time that caves were occupied as home sites. Mud was all they could find for building walls. It took lots of water to make mud and theu it was so soft and crumbly that the little walls cracked and fell when they dried out. Soon it was found that by picking up small

The stones and packing them into the soft mud as temper the walls would stand longer. Larger rocks and less mud made better
