Fortunately for the white races, these barbarians are not able to maintain peace among themselves. The Apaches and Cumanches are in continual strife, and never return from the "war path" without serious losses. It is not to be feared, therefore, that they will voluntarily join in a general rising against our pioneers; yet a common danger, or a common attack, might soon cement their hatred against the supposed usurper, and, directed by a man of capacity, produce even a more disastrous war than that with the Seminoles of Florida. The Cumanches are numerous and active. They are divided into Caihuas, Yamparicas, and Llaneros. The Apaches are braver than the Cumanches, and are known as Meselaros and Lipanes. These barbarians arm themselves with guns, rifles, lances, bows and arrows. They manage their weapons admirably, are agile horsemen, and shoot with unerring aim. Tall and majestic in figure; muscular and capable of enduring fatigue; accustomed to live on the simplest food of the forest and to win it when necessary by the arrow alone; uniting the sagacity of men with the instinct of animals, these knights of the southern wilderness realize perfectly our ideas of the daring aborigines who peopled this continent before it was subdued by the white man. Their hatred of the Mexicans and the savage fury with which they pursue their male captives of adult age, appear to denote even a stronger, if not a worthier motive than robbery in their attacks. At least six hundred women and children are borne off by them every year from the settlements to their mountain fastnesses, and they openly confess that they are not unwilling to improve their race by mingling it with the white. In order to maintain the southern frontier intact from these savages, Mexico designs the establishment of these military colonies, and will, in all probability, support them by a second or rear line of troops from the regular army as well as by forts and strongholds erected in positions affording easy access from the wilderness to inhabited regions. A frontier so open, and thronged with such barbarous hordes, could not be protected by military colonies alone. * * * * * The principal FORTRESSES and strongholds of Mexico have hitherto been those of Perote, Acapulco, Ulua, and the citadels at Mexico and Monterey. The present government has ordered the citadel of Mexico, situated a short distance out of the town to be abandoned, as it only formed a nucleus for the assemblage of the military factionists who have constantly disturbed the peace of the republic. The citadel of Monterey is to be maintained and suitably supported.
