A large portion of the revenue, both of Monte Video and of Province of Buenos Ayres, is raised by taxes on the importation of foreign goods, and the rate of duties is not excessive in either case. It is not on this account that any one complains of the Buenos Ayrean Government, but because it confines foreign commerce to the single port of Buenos Ayres, and excludes both foreigners and foreign vessels from the other ports of the Confederation, as strictly as the Chinese formerly excluded them from every port except Canton. This it is able to effect by its command over the entrance to the river Parana, the direct route to Entre Rios, Corrientes, and the other provinces of the Confederation. Whilst the provincial Government of Buenos Ayres thus excludes all foreign vessels from the Parana, and as far as its control extends from the Uruguay, it claims the right to expend the whole of the customs' revenue raised at Buenos Ayres. The upper provinces very naturally consider this unjust, and insist on having either a share of the revenue collected at Buenos Ayres (somewhat on the principle adopted amongst the states of the German Zollverein), or on having a general Congress of all the provinces of the Confederation to decide how the money shall be distributed. This General Rosas and his adherents refuse, and this refusal, coupled with the equally positive refusal of the same parties to allow foreign vessels to ascend the river, is one principal cause of the frequent wars between the states of the Argentine Confederation on the banks of the river and the Government of Buenos Ayres, one of which is now raging between it and Corrientes. In this way the commerce with the interior is continually interrupted. The policy of the Monte Videan Government is in every respect the reverse of this, for it not only throws open the ports of Monte Video, Maldonado, and Colonia, on the River Plate, but those of Soriano and Paysandu, on the Uruguay, the Yaguaron, on the Laguna Merin, and the dry port of Taquarembo on the Brazilian frontier to all the world, and thus gives every part of the republic all the advantages of foreign commerce.
