It is the ideal land for tuberculosis, though all invalids should be examined as to heart action before attempting any altitude over 4,000 feet. And the Southwest has worked out an ideal system of treatment for tuberculosis patients. They are no longer housed in stuffy hotels and air tight, super-heated sanitariums. Each sanitarium is now a tent city—portable houses or tents floored and boarded halfway up, with the upper half of the wall a curtain window, and a little stove in each tent. Each patient has, if he wants it, a little hospital all to himself. There is a central dining-room. There is also a dispensary. In some cases, there are church and amusement hall. Where means permit it, a family may have a little tent city all to itself; and they don't call the tent city a sanitarium. They call it "Sun Mount," or "Happy Cañon," or some other such name. The percentage of recoveries is wonderful; but the point is, the invalids must come in time. Wherever you go along the borders of Old and New Mexico searching for prehistoric ruins, you come on these tent cities.

Where can one see these cliff and cave dwellings of a prehistoric dwarf? Please note the points. Cliff and cave dwellings are not the same. Cliff dwellings are houses made by building up the front of a natural arch. This front wall was either in stone or sun-baked adobe. Cave dwellings are houses hollowed out of the solid rock, a feat not so difficult as it sounds when you consider the rock is only soft pumice or tufa, that yields to scraping more readily than bath brick or soft lime. The cliff dwellings are usually only one story. The cave dwellings may run five stories up inside the rock, natural stone steps leading from tier to tier of the rooms, and tiny porthole windows looking down precipices 500 to 1,000 feet. The cliff dwellings are mostly entered by narrow trails leading along the ledge of a precipice sheer as a wall. The first story of the cave dwellings was entered by a light ladder, which the owner could draw up after him. Remember it was the Stone Age: no metals, no firearms, no battering rams, nor devices for throwing projectiles. A man with a rock in his hand in the doorway of either type of dwelling could swiftly and deftly and politely speed the parting guest with a brickbat on his head. Similar types of pottery and shell ornament are found in both sorts of dwellings; but I have never seen any cliff dwellings with evidences of such religious ceremony as in the cave houses. Perhaps the difference between cliff folk and cave folk would be best expressed by saying that the cliff people were to ancient life what the East Side is to us: the cave people what upper Fifth Avenue represents. One the riff-raff, the weak, the poor, driven to the wall; the other, the strong, the secure and defended.

You go to one section of ruins, and you come to certain definite conclusions. Then you go on to another group of ruins; and every one of your conclusions is reversed. For instance, what drove these races out? What utterly extinguished their civilization so that not a vestige, not an echo of a tradition exists of their history? Scientists go up to the Rio Grande in New Mexico, see evidence of ancient irrigation ditches, of receding springs and decreasing waters; and they at once pronounce—desiccation. The earth is burning up at the rate of an inch or two of water in a century; moisture is receding toward the Poles as it has in Mars, till Mars is mostly arid, sun-parched desert round its middle and ice round the Poles. Good! When you look down from the cliff dwellings of Walnut Cañon, near Flagstaff, that explanation seems to hold good. There certainly must have been water once at the bottom of this rocky box-cañon. When the water sank below the level of the springs, the people had to move out. Very well! You come on down to the cave dwellings of the Gila. The bottom falls out of your explanation, for there is a perpetual gush of water down these rock walls from unfailing mountain springs. Why, then, did the race of little people move out? What wiped them out? Why they moved in one can easily understand. The box cañons are so narrow that half a dozen pigmy boys deft with a sling and stones could keep out an army of enemies. The houses were so built that a child could defend the doorway with a club; and where the houses have long hallways and stairs as in Casa Grande, the passages are so narrow as to compel an enemy to wiggle sideways; and one can guess the inmates would not be idle while the venturesome intruder was wedging himself along. Also, the bottoms of these box-cañons afforded ideal corn fields. The central stream permitted easy irrigation on each side by tapping the waterfall higher up; and the wash of the silt of centuries ensured fertility to men, whose plowing must have been accomplished by the shoulder blade of a deer used as a hoe.

Modern pueblo Indians claim to be descendants of these prehistoric dwarf races. So are we descendants of Adam; but we don't call him our uncle; and if he had a say, he might disown us. Anyway, how have modern descendants of the dwarf types developed into six-foot modern Pimas and Papagoes? It is said the Navajo and Apache came originally from Athabasca stock. Maybe; but the Pimas and Papagoes claim their Garden of Eden right in the Southwest. They call their Garden of Eden by the picturesque name of "Morning Glow."

How reach the caves of the dwarf race?

To the Gila group, you must go by way of Silver City; and better go in with Forest Service men, for this is the Gila National Forest and the men know the trails. You will find ranch houses near, where you can secure board and room for from $1.50 to $2 a day. The "room" may be a boarded up tent; but that is all the better. Or you may take your own blanket and sleep in the caves. Perfectly safe—believe me, I have fared all these ways—when you have nearly broken your neck climbing up a precipice to a sheltered cave room, you need not fear being followed. The caves are clean as if kalsomined from centuries and centuries of wash and wind. You may hear the wolves bark—bark—bark under your pillowed doorway all night; but wolves don't climb up 600-foot precipice walls. Also if it is cold in the caves, you will find in the corner of nearly all, a small, high fireplace, where the glow of a few burning juniper sticks will drive out the chill.

What did they eat and how did they live, these ancient people, who wore fine woven cloth at an era when Aryan races wore skins? Like all desert races, they were not great meat eaters; and the probabilities are that fish were tabooed. You find remains of game in the caves, but these are chiefly feather decorations, prayer plumes to waft petitions to the gods, or bones used as tools. On the other hand, there is abundance of dried corn in the caves, of gourds and squash seeds; and every cave has a metate, or grinding stone. In many of the caves, there are alcoves in the solid wall, where meal was stored; and of water jars, urns, ollas, there are remnants and whole pieces galore. It is thought these people used not only yucca fiber for weaving, but some species of hemp and cotton; for there are tatters and strips of what might have been cotton or linen. You see it wrapped round the bodies of the mummies and come on it in the accumulation of volcanic ash.
