Adjoining each hospital, agricultural centres will be founded wherein to localize 100 families at the least, these agricultural centres will have for their object the production of the alimenticiary products necessary for the supply of the said hospitals, the cultivation and extensive breeding of the plants and animals consumed as food by the neighboring population located all around, and the constitution of fixed centres of population which shall help towards the increased peopling of the region. The Government will assist the emigrants in the acquiring of lands and shall furnish them with food stuffs at a low price and their maintenance during the initial period. * * * * * Amongst the improvements and means tending to facilitate transport and diminish its cost in the valley of the Amazon, the construction of systems of railways and the betterment of the navigability of the rivers most peopled, is of great importance. The network of iron roads will be of two different categories: systems of great lines forming an integral part of the general Federal system of railroads and a network of economic narrow-gauged railways having the character simply of penetration lines. Belonging to the first of these categories the following networks will be commenced at once, and constructed within the shortest space of time possible: 1º starting from Belém de Pará and joining onto the general railway system in Pirapóra, Minas Geraes and in Coroatá, in Maranhão, with the necessary branches to connect the initial or terminal point of navigation on the rivers Araguaya, Tocantins, Parahyba and S. Francisco; 2º starting point from the Madeira e Mamoré Railway in the proximity of the mouth of the Abunã, passing by the town of Rio Branco and by the most appropriate point between Senna Madueira and Catay and terminating in the town of Thaumaturgo, with branch line right up to the frontier of Perú, along the valley of the river Purús. The construction and renting out of these railways will be done in competition by Public Tender. The concession for the railways of the second category shall only be made to those who undertake to colonize and exploit in proportion as that may be justified, the respective marginal lands, i.e., the land lying along each side of such said lines. The Government will concede a subsidy of 25:000$000 per kilometre constructed; the technical conditions are: a line of the Decauville portatil, the weight of the rails being 50 kilos per metre, with a gauge of 0.60 between the rails and the minimum radius of the curve 40 meters inclination 0.10 and weight of the locomotives in full working order, 18 to 20 tons.
