"The country," says the lieutenant, "from the Arkansas to the Colorado, a distance of over 1200 miles, in its adaptation to agriculture, has peculiarities which must for ever stamp itself upon the population which inhabits it. All North Mexico, embracing New Mexico, Chihuahua, Sonora, and the Californias, as far north as the Sacramento, is, as far as the best information goes, the same in the physical character of its surface, and differs but little in climate and products. In no part of this vast tract can the rains from heaven be relied upon, to any extent, for the cultivation of the soil. The earth is destitute of trees, and in great part also of any vegetation whatever. A few feeble streams flow in different directions from the great mountains, which in many places traverse this region. These streams are separated, sometimes by plains, and sometimes by mountains, without water and without vegetation, and may be called deserts, so far as they perform any useful part in the sustenance of animal life.
"The whole extent of country, except on the margin of streams, is destitute of forest trees. The Apaches, a very numerous race, and the Navajoes, are the chief occupants, but there are many minor bands, who, unlike the Apaches and Navajoes, are not nomadic, but have fixed habitations. Amongst the most remarkable of these are the Soones, most of whom are said to be Albinoes. The latter cultivate the soil, and live in peace with their more numerous and savage neighbours. Departing from the ford of the Colorado in the direction of Sonora, there is a fearful desert to encounter. Alter, a small town, with a Mexican garrison, is the nearest settlement. All accounts concur in representing the journey as one of extreme hardship, and even peril. The distance is not exactly known, but it is variously represented at from four to seven days' journey. Persons bound for Sonora from California, who do not mind a circuitous route, should ascend the Gila as far as the Pimos village, and thence penetrate the province by way of Tucson. At the ford, the Colorado is 1,500 feet wide, and flows at the rate of a mile and a half per hour. Its greatest depth in the channel, at the ford where we crossed, is four feet. The banks are low, not more than four feet high, and, judging from indications, sometimes, though not frequently, overflowed. Its general appearance at this point is much like that of the Arkansas, with its turbid waters and shifting sand islands."
The narrative of Lieut. Emory, of his journey from this point across the Desert of California, becomes highly interesting and characteristic.
"November 26.—The dawn of day found every man on horseback, and a bunch of grass from the Colorado tied behind him on the cantle of his saddle. After getting well under way, the keen air at 26° Fahrenheit made it most comfortable to walk. We travelled four miles along the sand butte, in a southern direction; we mounted the buttes and found a firmer footing covered with fragments of lava, rounded by water, and many agates. We were now fairly on the desert.
"Our course now inclined a few degrees more to the north, and at 10, A.M., we found a large patch of grama, where we halted for an hour, and then pursued our way over the plains covered with fragments of lava, traversed at intervals by sand buttes, until 4, P.M., when, after travelling 24 miles, we reached the Alamo or cotton-wood. At this point, the Spaniards informed us, that, failing to find water, they had gone a league to the west, in pursuit of their horses, where they found a running stream. We accordingly sent parties to search, but neither the water nor their trail could be found. Neither was there any cotton-wood at the Alamo, as its name would signify; but it was nevertheless the place, the tree having probably been covered by the encroachments of the sand, which here terminates in a bluff 40 feet high, making the arc of a great circle convexing to the north. Descending this bluff, we found in what had been the channel of a stream, now overgrown with a few ill-conditioned mesquite, a large hole where persons had evidently dug for water. It was necessary to halt to rest our animals, and the time was occupied in deepening this hole, which, after a strong struggle, showed signs of water. An old champagne basket, used by one of the officers as a pannier, was lowered in the hole, to prevent the crumbling of the sand. After many efforts to keep out the caving sand, a basket-work of willow twigs effected the object, and, much to the joy of all, the basket, which was now 15 or 20 feet below the surface, filled with water. The order was given for each mess to draw a kettle of water, and Captain Turner was placed in charge of the spring, to see fair distribution.
"When the messes were supplied, the firmness of the banks gave hopes that the animals might be watered, and each party was notified to have their animals in waiting; the important business of watering then commenced, upon the success of which depended the possibility of their advancing with us a foot further. Two buckets for each animal were allowed. At 10, A.M., when my turn came, Captain Moore had succeeded, by great exertions, in opening another well, and the one already opened began to flow more freely, in consequence of which, we could afford to give each animal as much as it could drink. The poor brutes, none of which had tasted water in forty-eight hours, and some not for the last sixty, clustered round the well and scrambled for precedence. At 12 o'clock I had watered all my animals, thirty-seven in number, and turned over the well to Captain Moore. The animals still had an aching void to fill, and all night was heard the munching of sticks, and their piteous cries for more congenial food.
"November 27 and 28.—To-day we started a few minutes after sunrise. Our course was a winding one, to avoid the sand-drifts. The Mexicans had informed us that the waters of the salt lake, some thirty or forty miles distant, were too salt to use, but other information led us to think the intelligence was wrong. We accordingly tried to reach it; about 3, P.M., we disengaged ourselves from the sand, and went due (magnetic) west, over an immense level of clay detritus, hard and smooth as a bowling-green. The desert was almost destitute of vegetation; now and then an Ephedra, Oenothera, or bunches of Aristida were seen, and occasionally the level was covered with a growth of Obione canescens, and a low bush with small oval plaited leaves, unknown. The heavy sand had proved too much for many horses and some mules, and all the efforts of their drivers could bring them no further than the middle of this desert. About 8 o'clock, as we approached the lake, the stench of dead animals confirmed the reports of the Mexicans, and put to flight all hopes of being able to use the water.
"The basin of the lake, as well as I could judge at night, is about three-quarters of a mile long and half a mile wide. The water had receded to a pool, diminished to one half its size, and the approach to it, was through a thick soapy quagmire. It was wholly unfit for man or brute, and we studiously kept the latter from it, thinking that the use of it would but aggravate their thirst. One or two of the men came in late, and, rushing to the lake, threw themselves down and took many swallows before discovering their mistake; but the effect was not injurious except that it increased their thirst. A few mezquite trees and a chenopodiaceous shrub bordered the lake, and on these our mules munched till they had sufficiently refreshed themselves, when the call to saddle was sounded, and we groped silently our way in the dark. The stoutest animals now began to stagger, and when day dawned scarcely a man was seen mounted.
"With the sun rose a heavy fog from the south-west, no doubt from the gulf, and, sweeping towards us, enveloped us for two or three hours, wetting our blankets and giving relief to the animals. Before it had disappeared we came to a patch of sun-burned grass. When the fog had entirely dispersed we found ourselves entering a gap in the mountains, which had been before us for four days. The plain was crossed, but we had not yet found water. The first valley we reached was dry, and it was not till 12 o'clock, M., that we struck the Cariso (cane) creek, within half a mile of one of its sources, and although so close to the source, the sands had already absorbed much of its water, and left but little running. A mile or two below, the creek entirely disappears. We halted, having made fifty-four miles in the two days, at the source, a magnificent spring, twenty or thirty feet in diameter, highly impregnated with sulphur, and medicinal in its properties.
"The desert over which we had passed, ninety miles from water to water, is an immense triangular plain, bounded on one side by the Colorado, on the west by the Cordilleras of California, the coast chain of mountains which now encircles us, extending from the Sacramento river to the southern extremity of Lower California, and on the north-east by a chain of mountains, running southeast and northwest. It is chiefly covered with floating sand, the surface of which in various places is white, with diminutive spinelas, and everywhere over the whole surface is found the large and soft muscle shell. I have noted the only two patches of grass found during the 'jornada.' There were scattered, at wide intervals, the Palafoxia linearis, Atriplex, Encelia farinosa, Daleas, Euphorbias, and a Simsia, described by Dr. Torrey as a new species.
