(26-27)        On the hot and dry land in Africa, a group of thirsty elephants were heading for awater pool less than a mile away. Not knowing why, all of the elephants stopped, withtheir big ears standing high up in the air.

But, what about animals? Animals' communication has been interesting scientistsall around the world. After a long time of studying, they have found some reallysurprising facts. Let's go back to those elephants we just talked about. We can see fromthe elephants' acts that they're listening to something, and what they have heard tellsthem to run away. Scientists have found that elephants have their own language to speakwith others far away. This special language is spoken infrasound -- sound which is solow that it can't be heard by our ears.        Now do you still think man is the only animal that can "'talk" to each other?
