The only point of advantage of the Victoria Falls is their height. The present chief source of wealth in Misiones is the various kinds of timber and valuable cabinet-maker’s woods found in its virgin forests. One day Misiones will doubtless export its rosewood and other beautiful and valuable products of its forests, which also produce pine and other building timber of superior quality to that which Argentina now imports from Europe. Transport of timber is effected by means of tying it into huge rafts which go down river as far as Corrientes. The timber supply of Misiones will long continue rich, since the tendency of the forest is ever to encroach on the surrounding land. A growing industry on which great expectations are based is the cultivation of the Ilex Paraguayensis, or mate shrub. The consumption of mate or Paraguayan tea, as it is sometimes called in Europe, is enormous throughout both of the River Plate Republics, which now import very large quantities annually from Paraguay and Brazil, while no sort of good reason seems to exist why the northern districts of Argentina should not grow sufficient to meet the home consumption. The Jesuits evidently appreciated and cultivated this shrub, but they had the secret of growing it from seed, a secret the true re-discovery of which by modern horticulturists is not yet quite proved.[34] Up till quite recently all Misiones mate yerba has been gathered from the abundant virgin growth of the shrub. Once Misiones produced larger quantities of sugar than it does now; and there is no reason why this industry should not revive from the almost total paralysis which it at present suffers; nor why one day the wine output of Misiones should not be improved in both quality and quantity. Maize naturally grows well (it yields in six months) in Misiones; which Territory with the general warmth of its climate, sufficient rainfall and heavy dews, is most favourable to tropical and subtropical vegetation. Oranges, of course, bananas, pineapples, and guavas grow practically, if not quite, wild and ground nuts and the castor-oil plant are among its many valuable products. The whole of Misiones is well watered by a network of very numerous streams, and if its atmosphere by day is rather reminiscent of a hothouse, the nights are usually cool and refreshing. The unevenness of its surface, while precluding much idea of extensive cultivation, is admirably suited for the shelter and care of the best natural produce of this exotically picturesque region.
