Alarm Signal
Animal alarm calls and cries can, in fact, serve at least two distinct purposes. The first, obviously, is to warn other members of the group about the presence of predators or perceived dangers. Among some animals, these can be quite specialized. The African meerkat, for example, uses different cries for hawks and for snakes. The other purpose, a little humorously, is to drive away other group members so that the alarm-giving animal can enjoy lone access to a food source. Here the animal relies on its fellows’ instinctual response to flee at the sound of an alarm without stopping to see if danger is actually present.

Modern science and inventions are revolutionizing the endurance; future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogs that earlier discoverers found so invaluable and hardly comparable.
Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the mapping of the whole of the interior presents a formidable task to the cartographers who undertake the work. Once their labors
