In the space of twenty years the Pampa, once regarded as a sterile waste, almost impossible of cultivation or of settlement, has seen a great development. It contains to-day more than 80,000 inhabitants; twenty centres of population: about 914,000 acres under cultivation; 464,645 cattle; 4,809,077 sheep, and 281,537 horses; with an annual export of products estimated at 15 millions of paper piastres, or £1,280,000. Its soil has greatly risen in value; the square league of 2500 hectares (or 6175 acres, or a square nearly 3·14 miles on the side, or just under 10 square miles) sells for anything up to 100,000 paper piastres, or £8800; and even in the remoter cantons it will sell for £3500 or £4400. This extraordinary progress has been accomplished quite recently; it dates back hardly three years, and the prices tend to increase each day. Before completing this sketch of the agricultural products of the Argentine, according to the official statistics, we must remind the reader that the total of these products increases by leaps and bounds, so that the figures given must be regarded as strictly provisional, on account of the great development to be foreseen as new centres of colonisation are formed. The Pampa Central, of which we have just spoken as a very mine of wealth, is capable of producing in the future enough meat and grain to nourish a great part of the population of the world. In the Argentine men employ, for the more important crops, such as wheat, maize, linseed, lucerne, etc., the latest and most perfect agricultural implements and machines; cultivators, ploughs, drills, harvesters, etc., etc. We have not space to mention all; but it is enough to say that in the regions where farming on a large scale is the rule, a progressive spirit is in the air, which impels the owners of great establishments, and even simple settlers, to furnish themselves with the very best machinery, for which they sometimes pay considerable sums. That agriculture has achieved the rapid expansion of which we have just given details, notwithstanding the little help which immigration has lately rendered, is due principally to the employment of the perfected machinery in common use. The best types of ploughs, harrows, drills, and reapers of all kinds——binder-reapers, traction-engines, winnowing and thrashing machines, all of the best construction and the most recent model——are familiar to the Argentine farmer, who makes constant use of them.
