"The real wealth of the province of Buenos Aires," says Dean Funes, "was, and always will be, the trade in hides" (_la pellejeria_).[87] A good part of the hides exported came from the hunting of the wild cattle and horses which had grown numerous on the area of the Pampa beyond the Rio Salado.[88] It was mainly after 1778, when trade with Spain had been authorized and there was an increased demand for hides, that the hunting of these ownerless beasts was taken up. Two thousand Spaniards from Buenos Aires, Santa Fe and Mendoza hunted every day, says D'Azara, killing an animal for each of their meals in addition to those they killed for hides. From 1775 to the Revolution, the Spanish Government made continuous efforts to regulate and reduce the massacre of the herds. It laid down penalties for every person selling hides that did not bear his own mark; it farmed out the right to hunt animals with no mark, and organized the destruction of wild dogs, etc. The ranches developed under shelter of this legislation. Still, the Revolution did not witness the end of this cattle-hunting. D'Orbigny took part in 1828 in two hunts of wild horses (_baguales_) in Entre Rios. The Argentine _gaucho_ long retained the ways of a hunter rather than those of a breeder in the strict sense; witness Urquiza's soldiers who, says Demersay, during the campaign of 1846, when they could not find trees to which they could fasten their horses, killed cattle and tied the reins to their horns.

[88] The number of wild animals and the area over which they roamed have often been exaggerated. It does not look as if they ever covered the whole of the Pampean plain. A salter who crossed Patagonia and the whole of the Pampa in 1753 (_Voyage du San Martin au fort de San Julian_, Coll. de Angelis, v.) only found wild herds near the Salado frontier, and he knew by this that he was close to the ranches. At the beginning of the nineteenth century there were no wild cattle left on the right bank of the Parana. There were still some in Entre Rios.
