At Gila Bend, some fifty miles from Maricopa Wells, the river makes a sharp curve north, and the road leaves it, for a direct course across the Bend to Maricopa Wells. This embraces what is known mainly as the Maricopa Desert—a wide circuit of level country, practically a waterless desert, though with some good land here and there. In wet seasons and during rainy months, water remains in a few holes near the middle of the Desert; but we found all long since dry. The distance is usually made in two stages, water being carried along for drinking and cooking purposes; but our "outfit" was light, and taking an early start and driving late, we pushed through in one. The Desert itself, as level as a house-floor, is covered with a sort of fine gravel, that makes an excellent road, over which our wheels rolled easily. Near its eastern borders, a range of barren mountains crosses the Desert from north to south, apparently blocking the way; but the road climbs along through a narrow cañon, that opens as you approach, and makes the plains beyond very readily. This cañon is a noted resort of the dread Apaches, and several attacks had recently occurred here. Before leaving Fort Yuma we had been told we would find hostile Indians here, if anywhere. But we took the precaution to dismount from our ambulances, and skirmish through on foot; and consequently, Señors Apaches failed to show themselves, if there. Our experience was the same all the way to Tucson. Subsequently, while en route thither, we passed several other places, where we had been warned to look out for Apaches, especially at Picacho, where the mountains crowd down to the road, and form something like a cañon again. But a prudent vigilance by day, and a few simple precautions by night, carried us safely through; and we were more than ever convinced, that the great majority of Indian attacks come from carelessness and neglect, on the part of the attacked.

A few miles west of Gila Bend, between Berk's Station and Oatman's Flat, we passed a group of rocks, that interest everybody, but which nobody seemed to know much about. They stand near the roadside, and consist of smooth red porphyry, or some such stone, curiously carved with figures of men, birds, beasts, fishes, etc. Many of the figures are now quite indistinct, but sufficient remain to show what they were, and their very indistinctness—coupled with the hardness of the stone—proves their great antiquity. The rocks themselves, when struck, ring like genuine clink-stones; and, it would seem, only the sharpest and hardest instruments could make much impression on them. The place is called "Painted Rocks," and we had only time for a cursory examination; but the sculpturing seemed too remote for Spanish times, and was generally attributed to the days of the Aztecs. However this may be, they appeared to be there as a species of hieroglyphics, and doubtless have a story to tell, that some future Champollion may unfold. It may be, that the ancient travel for Mexico left the Gila here, or about here, and struck across the country for the Santa Cruz and so south, flanking the Maricopa Desert, and that these sculptured rocks record the place as the starting-point—as a sort of finger-board or mile-stone. This is only a conjecture; but here, at least, is work for the archæologist and antiquarian, as well as at so many other points in Arizona.

With the exception of some mesquite, iron-wood, and palo-verde trees, scattered here and there along the Gila and its bottoms, the whole country from Yuma to Tucson is practically treeless, and must continue so from want of rains. Sage-brush and grease-wood abound, as in Utah and Idaho, and throughout the great internal basin of the continent generally; and on the uplands, you find the great columnar cactus in full vigor and maturity. Indeed, from the time we struck the Colorado Desert, we were fairly into the cactus region of the continent, but the varieties were few, and the size moderate, till we got well into Arizona. Here they increased in height and bulk, until we reached the Maricopa Desert, where we found them thirty and forty feet high, by two or three feet in diameter, with perpendicular branches halfway up, nearly half as large as the main stem. This variety is a green fluted column, with its edges armed with semi-circular thorns, and bears a cluster of apples on top, from which the Indians extract a rude molasses or sugar. Inside, it is a frame-work of reedy poles, that serve many useful purposes in that woodless region. These immense cacti dot the country over to Tucson, and beyond—indeed, down to Mexico, and largely through it—and are a leading feature of southern Arizona. Sometimes you miss them altogether; but, as a rule, they occur more or less on the mesas or plateaus nearly everywhere, and seem in the distance like monumental columns. Their clustering groups and varying heights, when seen from afar, have all the effect of a rural cemetery; only here the shafts are emerald green, instead of marble white. In fights with the Indians, they often prove of value as a defence, and their huge trunks secrete a fluid much akin to water, that has saved the life of many a thirsty traveller, when lost amid these arid wastes. How such a gigantic vegetable or immense plant can thus nourish here, where nothing else comparatively will grow, is a continuing mystery and perpetual astonishment. It would seem more fit for a luxuriant soil and a tropical climate. Yet here it is, magnum opus, mocking the naturalist apparently to scorn.

At Maricopa Wells, and thence up the Gila, we found a large settlement of the Maricopa and Pimo Indians. The Maricopas, it seems, are an offshoot of the Yumas, and number less than a thousand souls. The Pimos foot up five or six thousand, and from them are sprung the Papagos—a great tribe dominating all southern Arizona. The Maricopas and Pimos have a Reservation here together, some twenty-five miles long by four or five wide, embracing both sides of the Gila, and live in twelve different villages scattered over it. Two of these are occupied wholly by Maricopas—the rest, by Pimos. Both tribes are a healthy, athletic, vigorous-looking people, and they were decidedly the most well-to-do aborigines we had yet seen. Unlike most Indians elsewhere, these two tribes are steadily on the increase; and this is not to be wondered at, when one sees how they have abandoned a vagabond condition, and settled down to regular farming and grazing. They have constructed great acequias up and down the Gila, and by means of these take out and carry water for irrigating purposes, over thousands of acres of as fine land as anybody owns. Their fields were well fenced with willows, they had been scratched a little with rude plows, and already (March 9th) they were green with the fast springing wheat and barley. In addition, they raise corn, beans, melons, etc., and have horses and cattle in considerable numbers. One drove of their live stock, over two thousand head, passed down the road just ahead of us, subsequently when en route to Tucson, and we were told they had many more. The year before, these Indians had raised and sold a surplus of wheat and corn, amounting to two millions of pounds, besides a large surplus of barley, beans, etc. The most of this was bought by Indian traders, located at Maricopa Wells and Pimo villages, at from one to two cents per pound, coin, in trade; and then resold to the government, for the use of troops in Arizona, at from six to seven cents per pound, coin, in cash. This is a specimen of the way in which the old Indian Ring fleeced both the Indians and the government, and I give it as a passing argument in favor of the new policy. These Indians, it appears, have practiced agriculture somewhat from time immemorial, and they should be encouraged in it, as there is no surer way of "pacifying" or civilizing them. During the rebellion, they furnished two companies to the Union volunteers in Arizona, and the most of these had just re-enlisted, to serve as scouts against the Apaches. These wore a mongrel uniform, half Indian, half soldier; but the rest, only the traditional breech-cloth.

Their wigwams are oval-shaped, wicker-work lodges, made of poles, thatched with willows and straw, and this in turn overlaid with earth. An inverted wash-bowl, on an exaggerated scale, would not be a bad representation of one of them. They are usually five or six feet high in the centre, by fifteen or twenty in diameter, and would be very comfortable dwellings, were it not for their absurd doors. These are only about thirty inches high, by perhaps twenty wide, and consequently the only mode of entrance is on your hands and knees. While halting at the Pimo villages for a day, we managed to crawl into one, for the sake of the experience; but the smoke and the dirt soon drove us out. There was a dull fire in the centre, but with no means of exit for the smoke, except the low doorway. Rush or willow mats covered the rest of the floor, and on these three or four Pimos lay snoozing, wrapped in hides and blankets. Various articles of rude pottery, made by themselves, were stowed away under the eaves of the roof; and at the farther side, suspended from a roof-pole in a primitive cradle, was a pretty papoose sound asleep. As we crawled in, the venerable head of the family, raising himself on his elbow, saluted us with:

"Ugh! White man?"

To which, we, in true Arizona dialect, responded:

"How! Buenos dias, Señor!"

His dignified and elegant answer was:

"Heap good! 'Bacco? Matches?"
