demand of Spanish governors against the Chaco Indians, the Payaguás, and even against the distant Calchaquis, in what is now the province of Jujuy. Even when an English pirate, called in the Spanish histories Roque Barloque (explained by some to be plain Richard Barlow), appeared off Buenos Ayres, the undaunted neophytes shrank not a moment from going to the assistance of their co-religionists against the ‘Lutheran dog’.[193] Lastly, all Spanish governors and writers, both contemporaneous and at the end of the eighteenth century, seem to forget that if the Jesuits had an army of neophytes within their territory the fact was known and approved of at the court of Spain.[194] But it appears that Calvin had many coadjutors in his policy of ‘Jesuitas aut necandi aut calumniis opponendi sunt.’[195] When a Jesuit army took the field, driving before it sufficient cattle to subsist upon, and with its _caballada_ of spare horses upon its flank, it must have resembled many a Gaucho army I have seen in Entre Rios five-and-twenty years ago. The only difference seems to have been that the Gauchos of yesterday did not use bows and arrows, although they might have done so with as much benefit to themselves, and no more danger to their enemies, than was occasioned by the rusty, ill-conditioned guns they used to bear. The Indians were armed with bows, and in their expeditions each Indian carried one hundred and fifty arrows tipped with iron. Others had firearms, but all bore bolas on their saddles, and carried lazos and long lances,[196] which, like the Pampa Indians, they used in mounting their horses, placing one hand upon the mane, and vaulting into the saddles with the other leaning on the lance. The infantry were armed with lances and a few guns; they also carried bolas, but they trusted most to slings, for which they carried bags of hide, with a provision of smooth round stones, and used them dexterously. On several occasions their rude militia gave proofs of stubborn valour, and, as they fought under the Jesuits’ eyes, no doubt acquitted themselves as men would who looked upon their priests almost in the light of gods. But agriculture and cattle-breeding were not all the resources of the missions; for the Jesuits engaged in commerce largely, both with the outer world and by the intricate and curious barter system which they had set on foot for the mutual convenience of the different mission towns. In many of the inventories printed by Brabo, one comes across the entry ‘Deudas’, showing a sort of account current between the towns for various articles. Thus, they exchanged cattle for cotton, sugar for rice, wheat for pig-iron or tools from Europe; as no account of interest ever appears in any inventory as between town and town, it seems the Jesuits anticipated Socialism—at least, so far as that they bought and sold for use, and not for gain. Although between the towns of their own territory all was
