at from 150,000 to 160,000, which number would give about 1.3 for each English square mile. This is probably the actual number of inhabitants within the State, exclusive of Indians and some wild dwellers among the mountains who were not comprised in the census of 1833. Large numbers of aborigines occupy the lonelier portions of Chihuahua. Tribes of Tepehuanés, Llanos, Acotlames, Cocoyames and a few remnants of the Aztecs are found within its borders. In the Bolson de Mapimi, and on the borders of the mountain ranges of the Chanáte, El Diabolo Puerco, and Pilares, swarm numbers of the Apaches Mescaléros and Farones, who are often engaged in war with the savage and robber tribes of Cumanches, whose constant inroads into the Mexican territory are a source of incessant annoyance and insecurity to the people of the frontier. In the ravines and valleys of the Sierra de los Mimbres, in the north-west of the State, the Apache Mímbreños are found, while further south, in the wild and deep dells of Tararécua and Santa Sinforosa various bands of the Tarahuamares still pursue their hunter-life in perfect freedom.
