Is the next subdivision of New Spain which meets our attention in proceeding to the south. It is bounded on the north by the Rio Colorado, on the east by New Biscay, on the west by the great Californian gulf, and on the south by the intendancy of Guadalaxara. Under the title of Sonora, are comprehended the provinces of Pimeria, Sonora, Hiaqui, and Mayo, or Ostimuri, and Cinaloa. The capital of Sonora is Arispe; and its provinces lie from the Colorado River in the north to Culiacan on the south, following the order above mentioned; we shall begin therefore with Pimeria; and the description of climate, soil, &c., of each subdivision, will best explain the general appearance of the whole of Sonora, or as it is called in modern maps, New Navarre. PIMERIA. PIMERIA is the most northern district of this extensive division, and is bounded on the north by The Rio Colorado, by New Biscay on the east, by the Californian gulf on the west, and by Sonora on the south. Pimeria received its name from the Pimas, a tribe of Indians who inhabit this tract of country. It is subdivided into high and low Pimeria, and extends about three hundred miles to the north of Sonora. The climate is cold and moist, and the rains often last a week without intermission in the winter season, and torrents from the mountains during that period descend in all directions. Pimeria is very little known, being inhabited chiefly by the native tribes, the Spanish colonists frequently deserting it on account of the irruptions of a warlike race of savages, who inhabit the neighbouring country of Apacheria in New Mexico.
