There are few rivers or lakes on the Camp and there is little surface water. The old-fashioned wells sunk very deep in the ground, in which the buckets are raised by horse power, are still quite common. Windmills of American make add a picturesqueness to the landscape. Ponds are banked up into which the water is pumped, and from them the troughs are filled. These wells seldom go dry even in the severe drouths in that land. The midday siesta is almost universal in the Camp, for the sun beats down unmercifully hot for a few hours. The languor of these hours is all-pervading. Stock huddle together and put their heads in the shadow of the bodies of the others. The mosquito is very much at home on the Camp and sometimes makes the nights unappreciated. [Illustration: A GAUCHO AND HIS WIFE ON AN OUTING] One fearful disease is the anthrax, which is taken from cattle. The first symptom is a red mark on the skin, which is irritating. If unattended to this will develop into a blue boil surrounded by little blisters. After a while the sensitiveness disappears and no pain is felt. The blue is more pronounced and a full-fledged case of anthrax is developed. Something must be done promptly. The common treatment, when no surgeon is near, is to heat a wire red hot and burn out the infected spot clean from the surrounding flesh. This is a decidedly painful operation when performed without anæsthetics, and requires a remarkable degree of stoicism. The affected spot is absolutely without feeling. If this or another effective operation is not performed by the third day the chance of recovery is very slight, it is said. The gauchos are the principal sufferers.
