SANTAREM, a city of Brazil, at the head of a comarca in the province of Para, is situated on the right bank near the mouth of the Rio Tapajos, a right-hand tributary of the Amazon. It is a clean and neat-looking place, with rows of whitewashed houses in the European town, clusters of palm-thatched huts in the Indian suburb, a large church, the ruins of a stone fort, and, standing apart, the municipal buildings with tne courthouse. As the Rio Tapajos is navigable for steamers to the rapids, 170 miles above Santarem, and for boats to within a short distance of Diamantino, the town carries on a considerable trade with Matto Grosso and the country along the banks. The population and importance of the place, originally founded by a Jesuit missionary for his converts in 1661, and made a city in 1848, are steadily increasing.
