The cochineal plant is very common, but, hitherto, not appropriated to the production of that insect. Many parts are well adapted to the produce of indigo, the culture of which receives here no attention. The productions of those two vegetables, from their great value, are the only ones which the agriculturist of these districts could convey to the maritime ports with any considerable profit and security. The trees of incense, senna, and manna, are not unknown. Campeche and a species of rhubarb are also met with. Gold and cattle are the only objects of exportation, which introduce into the country what little may be found of luxury, and the necessaries of life required from without. If a little cotton wool, or coarse cotton cloth, with some hides, are conveyed to the eastern ports, it is only that the troops of animals may not proceed unladen on their journeys to bring back the necessary dry goods, salt, iron, &c.; these articles would not otherwise pay one-half of the expense of conveyance. At present, the breeders of cattle and senhors d’engenhos are the only individuals who live constantly independent; the same may be said of miners and traders, when they are favoured by fortune in their operations. None, however, experience want; and agriculture is proportioned to the population. The present king has been solicitous to increase both in this fine and fertile province; and, when Prince Regent, he afforded his countenance and support, in September, 1812, to a plan for establishing a commercial company between this province and Para, the funds of which were not to be less than one hundred thousand crusades. The establishment of warehouses and prezidios, in situations best adapted to promote the navigation of the Maranham, and Tucantines, from Arroios to Porto Real, where almost all the obstacles terminate which impede the navigation upwards, cannot fail with the requisite attention and wisdom to effect this desirable project. All members who entered this society with ten thousand crusades, besides other favours, were to obtain what is termed a _sesmaria_ of land, extending five miles in front and five miles in depth, upon the margin of the Maranham, the Tucantines, and the Araguaya; and those who established themselves either upon the margins or in the certams of those rivers, were to be exempt from the payment of tenths upon their productions, and to be free from the duties of entrance upon the articles of commerce navigated by the said rivers. RIVERS.--The Tucantines, the Araguaya, the Corumba, the Parannan, and the Parannahiba, are the principal rivers, and receive all the others which to a considerable number water this province.
