TUCUMAN, a province of Paraguay, in South America, bounded on the north by the provinces of Los-Chicas and Choco; on the east by Choco and Rio-de-la-Plata, on the south by the country of Chiquitos and Pampas, and on the west by the bishopric of St. Jago. The air is hot, and the soil sandy: however, some places are fruitful enough. The Spaniards possess a great part of this country.
