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 three­month­old calf struggling in the fast-rising water，and it was a life­and­death struggle. Her calf was floating(漂浮) 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 away.

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.
