They have not the power, if they possessed the will, even to restrain lawless Mexicans from passing the border and committing depredations on our remote settlers. A state of anarchy and violence prevails throughout that distant frontier. The laws are a dead letter and life and property wholly insecure. For this reason the settlement of Arizona is arrested, whilst it is of great importance that a chain of inhabitants should extend all along its southern border sufficient for their own protection and that of the United States mail passing to and from California. Well-founded apprehensions are now entertained that the Indians and wandering Mexicans, equally lawless, may break up the important stage and postal communication recently established between our Atlantic and Pacific possessions. This passes very near to the Mexican boundary throughout the whole length of Arizona.
