It is interesting to note how the rancheros occupied this district in advance of the government. Sanchez was a proprietor of Coahuila who, in search of grazing lands for his stock, had reached the Rio Grande. Similarly, Dn. José Vasquez Borrego, who in 1750 founded Dolores under the authority of Escandon, had previously pastured his stock and begun a settlement there. Prieto, Historia, 175, 187, 188.
