Those vast regions which occupy the central part of South America, stretching from Guinea to the foot of the Andes, overspread with gigantic and primeval forests, and watered by mighty rivers--those solitary wilds where man appears unessential in the scale of creation, and the traces of his power are few and far between--have lately occupied much of the attention of Europeans; partly from the extraordinary events and unexpected revolutions; which have convulsed the nations round them; and partly from the researches of enterprising travellers who have penetrated into their remotest districts. But till within the last twenty years these wild regions have been unknown, except through the means of the Spanish and Portuguese priests, settled as missionaries along the banks of the Orinoco and the Paraguay. The men thus devoted to utter banishment from all intercourse with civilized life, are generally Franciscan or Capuchin friars, born in the Spanish colonies. Their pious duties are sometimes voluntary, and sometimes imposed by the superiors of their order; in either case their destiny appears at first view deplorable, and their self-sacrifice sublime; yet, when we recollect that these poor monks generally exchanged the monotonous solitude of the cloister for the magnificent loneliness of the boundless woods and far-spreading savannahs, the sacrifice appears less terrible; even where accompanied by suffering, privation, and occasionally by danger. When these men combine with their religious zeal some degree of understanding and enlightened benevolence, they have been enabled to enlarge the sphere of knowledge and civilization, by exploring the productions and geography of these unknown regions; and by collecting into villages and humanizing the manners of the native tribes, who seem strangely to unite the fiercest and most abhorred traits of savage life, with some of the gentlest instincts of our common nature. But when it has happened that these priests have been men of narrow minds and tyrannical tempers, they have on some occasions fearfully abused the authority entrusted to them; and being removed many thousand miles from the European settlements and the restraint of the laws, the power they have exercised has been as far beyond control as the calamities they have caused have been beyond all remedy and all relief.
