"The Papagos and Pimas Indians, by proper management, might be made very useful, in working upon the road where there is not much rock excavation. They are unlike the Indians of Texas, or the Apaches, living in villages and cultivating the soil, besides manufacturing blankets, baskets, pottery, etc. Quiet and peaceable, they have no fears except from their enemies, the Apaches, and are very industrious, much more so than the lower order of Mexicans, and live far more comfortably. It is astonishing with what precision they construct their acequias—irrigating canals—some of them, the acequias madre, of very large size, and without the use of levelling apparatus, but simply by the eye. Their gardens and farms too are regularly ditched and fenced off into rectangles and circles, with hedges and trees planted as if done by more enlightened people."

The population of the new Territory of Arizona is at present not far from eight thousand, and is rapidly increasing. The Mesilla Valley and the Rio Grande are probably the most thickly populated, containing about five thousand people. A majority of the Mesilla inhabitants are Mexicans, but they will be controlled by the American residents, whose number and influence is constantly on the increase. The Santa Cruz Valley, in which are situated the towns of Tueson, Tubac, Tumacacari, and the mining settlement of Sopori and others, is, next to Mesilla, the most thickly settled. Tueson was formerly a town of three thousand inhabitants; but the majority have been driven off by the Apache Indians. It is fast becoming a thriving American town, and will before long be a place of more importance than ever before. Real estate is already held at high rates, and the erection of buildings shows that American energy is about to change the face of the last half century. Tubac had been completely deserted by the Mexicans. It has been reoccupied by the Sonora Exploring and Mining Company, and now boasts a population of several hundred. The Calabazas valley is also fast filling up with an American population, and another year will see the whole centre of the Territory dotted with settlements. Many of the fine claims on the San Pedro River have already been located by emigrants under the general pre-emption law, but until protection is afforded to the settlers, but little progress will be made in agricultural pursuits. The Apache Indian regards the soil as his own, and having expelled the Spanish and Mexican invader, he feels little inclination to submit to the American. A small settlement of Americans is growing up at Colorado city, opposite Fort Yuma, at the junction of the Gila and Colorado rivers. This point is destined to be one of great commercial and pecuniary importance. Situated at the present head of navigation, at the point where the overland mail route crosses the Colorado, and where the Southern Pacific Railroad must bridge the stream, it is a necessary stopping place for all travel across the country. Here are transhipped all the ores coming from the Territory, which find their way to market down the Colorado to the Gulf of California, thence by steamer or sailing vessel to their destination. Here all supplies of merchandise for the Territory are landed, and from this point forwarded to their various owners. A thriving commerce has already sprung up between Arizona and San Francisco. In almost any daily paper in San Francisco may be seen vessels advertised for the mouth of the Colorado. Two steamers find active employment in transporting government stores from the head of the Gulf of California to Fort Yuma, and goods to Colorado city for the merchants of Tueson, Tubac, Calabazas, and for the mining companies. Should the exploration of the Upper Colorado by Lieutenant Ives, United States Army, now in progress, prove successful, Colorado city will become still more important, as the surplus products of the rich valleys of New Mexico, Utah, and California to the north, will all find a market down the Colorado. Property in this new city is held at high rates, and by the last San Francisco News Letter is quoted at an advance. The population of Arizona Territory has much increased within a few months by emigration from California. The massacre of Henry A. Crabbe and his party by the Mexicans at Cavorca created a desire for revenge throughout all California. Companies have been formed, and large parties are settling in Arizona, near the Mexican line, with the ulterior object of overrunning Sonora, and revenging the tragedy in which was shed some of the best blood of the State. The appropriation by the last Congress of two hundred thousand dollars for the construction of a wagon road from El Paso to Fort Yuma, and the two mail contracts, semi-monthly and semi-weekly, which involve an expenditure of nine hundred thousand dollars per annum, will afford employment to a host of people, and draw at once to the neighborhood of the route an active and energetic population. The new wagon and mail route traverses the Territory of Arizona throughout its entire length. Along the mail route, at intervals, military posts will be established. These and the necessary grazing stations will create points around which settlements will at once grow up, and the country, now bare, will show everywhere thriving villages. The Southern Pacific Railroad, which will be built because it is necessary to the country, will find its way easily through Arizona.

It is no exaggeration to say that the mining companies, in their own interest, will be forced to subscribe enough to the stock of the company to insure its success. The Arizona Copper Mining Company is now paying $100 per ton for the transportation of its ores from the mines to Colorado city. One year's freight money at this rate would build many miles of the road. The silver mining companies will be only too glad to get their ores to market at so cheap a rate, as their proportion of the subscription to the railroad. Iron and coal are both found in the Territory,—the former especially in great abundance. Texas has guaranteed the road to El Paso, by her generous legislation; Arizona will build it, with her mineral wealth, to Fort Yuma, the eastern boundary of California, and California will do the rest. The first terminus of the Southern Pacific Railroad will doubt less be on the Gulf of California, at the Island of Tiburon, or more probably Guyamas. A steam ferry across the Gulf, a short railroad across the peninsula of Lower California to a secure harbor on the Pacific, (where a steamer will take passengers and freight in four days to San Francisco,) is the most natural course of this route. In view of this probability, all the available points for such a terminus on the Gulf have been, or are in progress of being, secured by capitalists, either by obtaining grants from the Mexican Government, or by purchase from private individuals. Already Guyamas is owned in great part by English and American capitalists. A port on the Gulf of California is necessary to our Pacific possessions, and must be ours sooner or later. The longer it is delayed, the worse for American progress on the Pacific. Arizona needs it at once, as a depot for the export of her ores, and for the import of goods for the supply of her population.

The Mormon war has closed for years the great emigrant road to California and Oregon, over the South Pass and Salt Lake valley, leaving open only the route along the 32d parallel of latitude, through Arizona. This route is by far the most practicable at all seasons of the year, and the closing of the South Pass route by the Mormon difficulty is an additional and urgent argument in favor of the early organization of this Territory. Fifty thousand souls will move towards the Pacific early in the spring, if the route is opened to a secure passage.

The present condition of Arizona Territory is deplorable in the extreme. Throughout the whole country there is no redress for crimes or civil injuries—no courts, no law, no magistrates. The Territory of New Mexico, to which it is attached by an act of Congress, affords it neither protection nor sustenance. The following extracts from letters received by the writer tell the story of the necessity for early action on the part of Congress, in urgent terms.

TUBAC, GADSDEN PURCHASE, August 15, 1857.

Affairs in the Territory have not improved. A party of Americans (our countrymen) had made an "excursion" into Sonora, captured a train of mules, and killed several Mexicans. Upon their return to the Territory with their ill-gotten booty, the citizens formed a company and took the property away from them, and returned it to the owners in Magdalena,
