     I suddenly heard an elephant crying as though frightened. Looking down, I immediately recognized that

something was wrong, and ran down to the edge of the near bank. There I saw Ma Shwe with her three-

month-old calf struggling in the fast-rising water and it was a life-and-death struggle. Her calf was floating

and screaming with fear. Ma Shwe was as near to the far bank as she could get, holding her whole body

against the rushing water and keeping the calf pressed against her huge body. Every now and then the rushing

water would sweep the calf a way.

     There was a sudden rise in the water and the calf was washed clean over the mother's body and was

gone. Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk (象鼻) against the

rocky bank. Then with a huge effort she picked it up in her trunk and tried until she was able to place it on

a narrow shelf of rock

     Just at this moment she fell back into the river. If she were carried down, it would be certain death. I

knew as well as she did, that there was one spot (地点) where she could get up the bank, but it was on the

other side from where she had put her calf

     While I was wondering what I could do next, I heard the sound of a mother's love. Ma Shwe had crossed

the river and got up the bank and was making her way back as fast as she could roaring (吼叫) all the time

but to her calf it was music.
