Two years have passed since Colonel J. A. B. Sandenbergh, the Warden of the Kruger National Park, launched a public appeal to provide water for the wild life of the park. Subscriptions were invited for two purposes: the first to provide boreholes so that in the dry season animals could find water within reach of their grazing, the second to form a general fund to build dams to retard the run-off of rain water.
