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.
