Answer -
To teach the master call to an elephant is the most difficult thing. Yet it is the most important signal for an elephant to learn. The master call is a strange hissing howling sound. It seems as if a snake and a tiger were fighting.
A trained elephant can be given the master call in its ears in a forest. The elephant knows that his master has lost his way. He therefore starts uprooting trees. Thus, he creates a path through the forest to the master’s house.
