Part 14 (1/2)
It was long believed that human beings had never been upon this rock, although there were traditions to the effect that a village once existed upon its summit. According to the tradition, the breaking away of a great ma.s.s of rock left the summit inaccessible ever afterward. The cliffs were scaled recently by the aid of ropes, and evidences were found in the shape of pottery fragments, to show that the Indians had once inhabited the mesa. Two or three miles away, across the valley, is the large village of Acoma, where a great deal of pottery is made for sale.
The pottery of the Pueblo Indians is very attractive, and their religious festivals and peculiar dances draw many visitors. These Indians no longer fear attacks from the savage Apache or Navajo, but they have become so used to their rock fortresses that it is not likely they will soon. leave them. The Navajos now live in peace and raise large herds of sheep and goats; while the more savage Apaches have been gathered upon reservations, never more to go upon the war-path. Most of the Apaches still live in their rude brush habitations.

While the Pueblo Indians make attractive pottery, the Navajos are noted for their blankets. The wool, which is taken from their herds, is dyed different colors, and woven upon their simple looms into the most beautiful and costly blankets.
We usually think of the native inhabitants of America as leading a wild and rude life, moving from place to place in search of food, and constantly engaged in warfare with one another. The Pueblo Indians alone are different. Possibly if the white man had never come to America these Indians might in time have become highly civilized. But it is more than likely that in their struggle with Nature in this wild and rugged country, where they were constantly subjected to attacks from their more savage neighbors, they would have sunk lower instead of rising, and would finally have disappeared.
The Apaches were dreaded alike by the agricultural Indians and the early Spanish. Issuing from their mountain fastnesses the Apaches would raid the unprotected villages and missions, and then retreat as quickly as they came. For many years after the American occupation prospectors had to be constantly on their guard, and many are the tragedies that have marked this remote corner of our country.
THE LIFE OF THE DESERT
During the blinding glare of summer the deserts of southwestern Arizona and the adjoining portions of California are forbidding in the extreme. Day after day the pitiless sun pours its heat upon the vast stretches of barren mountain and plain, until the rocks are baked brown and it seems as if every particle of life must have left the seared and motionless plants.
Month after month pa.s.ses without rain. Now and then light clouds float into sight, and occasionally rain can be seen falling from them, but they are so high that the drops all disappear in the dry and thirsty air long before they can reach the ground. Cloud-bursts may take place about the peaks of some of the higher mountains, but they have very little effect upon the life out on the plains.
Animals and plants brought to this region from a moister climate must drink continually to make up for the rapid evaporation of moisture from their bodies; a day without water may result in death.
And yet the living things that have homes in the desert can resist the dry air for many months without a renewal of their moisture.
There are areas where the average rainfall is less than three inches, and sometimes two years may pa.s.s without a drop of rain. It will certainly be worth our while to find out something about these desert plants and the way in which Nature enables them to get along with so little water.
Go where we will, from the moist heat of the tropics or the dry heat of the deserts to the icy north, we find that everywhere the plants and animals are suited to the climate of the particular place in which they live. Therefore we might conclude that they thrive better in those places than they would anywhere else, but that is not always true.
A struggle is going on continually among plants for a footing in the soil and for a share of the suns.h.i.+ne. The weaker plants are generally killed, while those hardy enough to survive have to adapt themselves to new conditions of life, becoming stunted and deformed upon barren slopes; but they have plenty of room there because fewer plants are striving for the same place.
It is not likely that the deserts of the southwest have always been as dry as they are now. As the amount of rainfall slowly lessened through thousands of years, the animals could migrate when it became too dry; but the plants, fixed in one place, had either to give up and die, or change their characters and habits to suit the demands of the changing climate. The fact that these extremely dry deserts are filled with plant life to-day is without doubt due to this ability to change.
In a moist, warm climate plants are luxuriant; they take up a large amount of water through their roots and evaporate it through the leaves. If placed in a desert, such plants would immediately wither and die. To avoid too rapid evaporation the bodies of the desert plants have become smaller, and their leaves have either shrunk greatly or wholly disappeared. Strong-smelling, resinous juices exude from the remaining leaves and stems, and form a surface varnish through which water pa.s.ses with difficulty.
Some forms of plant life, such as the p.r.i.c.kly-pear, are provided with fleshy stems which hold a supply of moisture to be drawn upon during the long dry season. Men and animals are sometimes saved from death by chewing the pulp of the p.r.i.c.kly-pear or other cactuses.
After a period of exceptional drought, the stems of the p.r.i.c.kly-pear lose their bright green color and become shrunken.

The development of the underground part of the plant is frequently out of all proportion to the part above the surface. The manzanita, which grows in the semi-arid climate of southern California, is a low shrub with branches that are rarely large enough for fuel.
The roots, however, are large and ma.s.sive, and are extensively used for firewood.
The desert plants are armed, not only against the dry air, but against the wandering animals which would bite them and suck their juices. The smell of the sagebrush is such that very few animals will touch it. Other plants are protected by thorns. In fact, the drier the region, the more th.o.r.n.y are its plants. A little shrub called the crucifixion thorn has no leaves at all, nothing but long, sharp spines. Besides the straight thorns there are curved and also barbed ones, for every conceivable form is represented among the plants of these dry lands.
As the desert plants are armed against the animals, so the animals are armed against each other. Many of the insects and reptiles are extremely poisonous; the greater the heat of their habitat, the more dangerous are their bites. The horned toad, while not poisonous, is protected by having h.o.r.n.y spines upon its head and back. The little rattlesnake known as the ”side-winder” is perhaps the most dangerous of all, although the tarantula, centipede, and scorpion are formidable foes. The Gila monster, long believed to be so dangerous, is now considered non-poisonous under ordinary conditions.

The desert tortoise is perhaps the most remarkable of all the animals of the desert. It is rare, and little is known of its habits except that it lives in the most arid valleys of southeastern California, far removed from any water. This tortoise has a diameter across its sh.e.l.l of at least eighteen inches. Its flesh is much prized by the Indians and prospectors. A specimen which had been without water for an indefinite period was dissected, and the discovery was made that upon each side there was a membranous sac, containing clear water, perhaps a pint in all. The desert tortoise, then, carries his store of water with him, and is thus enabled to go many months without a new supply.
