The Durham, Hereford and polled Angus are the chief grades of cattle that one will find. In one section of the country one breed will predominate, and a few leagues away another will prevail almost exclusively. Cattle are always sold at so much a head, and never by weight. “Do you never weigh them?” I asked of an _estanciero_. “Oh, yes, we weigh a few so that we have an idea of the general average.” In the transaction, however, between him and the buyer, weight is never mentioned. The buyer will look over the bunch for sale and offer a stated figure, which may or may not be accepted. They are then delivered to him at a given point, and shipped to the stockyards in Buenos Aires, or to one of the many slaughterhouses in the republic. The number of stock to be kept is a serious problem for the proprietor. More than one _estanciero_ has been ruined by overstocking his _estancia_, and then, either locusts or the drouth coming, he was left without feed for his animals. The cattle dip is a very necessary adjunct to every stock farm. The idea was adopted from Australia, where the cattle raisers had similar experience with the tick fever. It consists of a wide yard which gradually narrows into a lane wide enough for only one animal. When the animal is driven forward it faces a lengthy tank which it is necessary to ford. This tank is filled with a medicated solution and, as the animal swims through it, men with poles push them entirely under. The animal does not enjoy swimming through this nauseous, badly-tasting mixture, but he has no option, so, shutting his mouth tightly, he flounders through in the best way possible. It is rather a sorry looking creature, however, that emerges on the other side. Another form of dipping cattle is a cage into which an animal is driven, and this is submerged in a tank filled with this medicated solution. Either method accomplishes the desired result, which is to give the cattle a thorough saturation that will kill the tick. Second in importance comes sheep. Although they abound all over the republic they are found in greatest numbers in the southern provinces. The development of these animals has been studied a great deal lately and scientific methods have been introduced. The finest of rams have been imported in order to improve the breed and the former coarse wool is now being replaced by a much finer quality. The Argentine merinos will now rank with those from any part of the world. One will find Leicesters, Oxfords, Black-faced Downs and all the other fine breeds. A number of New Zealand ranchers have come to Argentina in recent years, and they have been especially successful in sheep raising. The breeds have been bettered, and foot-rot as well as other diseases combated with so that the results have been very beneficial to the industry.
