The most eastern fort of this intendancy is the Presidio of Nacogdoch, which is 68 leagues from the United Statesʼ Fort Clayborne.
The great river of this government is the Rio del Norte, which enters the Mexican gulf in about 25° 40ʹ north latitude, and 97° 20ʹ west longitude. The other rivers of most note are, beginning from the east, the Rio Mexicano, Rio de Sabina, Rio de la Trinidad, Rio Colorado de Texas, Rio St. Antonio, Rio de las Nueces, Rio de Tigre, to the south of the great Rio del Norte, and the Rio Panuco or Tampico; of all of which very little is known.
INTENDANCY OF ZACATECAS.
This intendancy is one of the smallest in New Spain, and is the first of those we are about to describe, which are under the immediate controul of the viceroy.
It is bounded on the north by the intendancy of New Biscay or Durango, on the east by San Luis Potosi, on the west by Guadalaxara, and on the south by Guanaxuato. It is 85 leagues long, and 51 broad in its greatest dimensions.
The population of this province is 153,300.
Zacatecas consists almost entirely of mountain country; so much so, as to have been said greatly to resemble Swisserland. The climate is very variable and inclement, and the soil far from fertile; but all this is compensated by the riches of the mines, which are only inferior to those of Guanaxuato.
Its chief town is Zacatecas, where the great mines are situated. The population of this town, is 33,000; it is a bishopʼs see, and is 240 miles north-north-east of Mexico.
The next is Sombrerete, the seat of the chief-council of mines; Fresnillo, near the latter, both of which are great mining stations. Sombrerete was formerly the richest of the whole, and there are many other mining stations of great importance in this district, most of which are very populous.
