Seventeen rivers and streams flow through the territory of this State. The Rio Bravo, or Rio Grande del Norte; the Rio Conchas; Florida; Chihuahua; Tonachi; Llanos; Casas Grandes; San Buenaventura; Carmen; Santa Isabel; Pasesiochi; Mulatos; Chiñapas; Parral; San Pedro; Batopilas; and Rio Grande de Bavispe. The lakes or lagunes are those of San Martin; Guzman; Patos, or Candelaria; Encinillas; and Castilla. The river Nasas, which rises in Durango debouches in the Lake of Cayman, in the Bolson de Mapimi. The climate resembles that of the adjoining State of Durango. In the year 1834, the population, according to official statistics was 145,182; at present, it is estimated 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 northwest of the State, the Apache Mimbreños 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.
There is some doubt, in consequence of the conflict of authorities, as to the divisions of the State of Chihuahua. According to the Noticias Estadisticas of Señor Escudero, published in 1834, it was composed of four districts: Chihuahua, Hidalgo, Paso del Norte, and Guadalupe y Calvo,—in the first of which are the partidos of Aldama, Cosihuiriachi, Papigochi, and Jesus Maria de Resales;—in the second, the partidos of Allende and Jimenez;—in the third, the partidos of Galeanas and Janos;—and in the fourth, those of Batopilas and Balleza or Tepehuanes. According to an article published by the same writer in the fourth volume of the Museo Mexicano, in 1844, he apparently entertains the opinion that the same divisions still continue; but, if the authority of another and very positive correspondent of the same work is to be relied on in refer-
