When Instinct Works — Class 8 English (Samacheer Kalvi)

TN State Board (Samacheer Kalvi) Class 8 English, Supplementary 5. How an animal's instinct saved human lives.


1. About the lesson

When Instinct Works (an episode from the famous story Black Beauty) shows how the special instinct God has given to animals can save human lives — and why we should care for and respect animals.

2. Summary

One morning late in autumn, John harnessed the horse Black Beauty to a new cart, and the Master, John and Black Beauty set out on a long journey. The weather was very windy with heavy rain. In one low part of the road, the flood water rose halfway up to Black Beauty's knees.

As they reached a wooden bridge, the moment Black Beauty's feet touched it, the horse sensed danger and made a dead stop, refusing to move. A man at the toll-gate flashed a torch and warned that the bridge was broken in the middle. Black Beauty's instinct had saved them — if the horse had not been wiser, all three would have drowned. John remarks that many people do not care for their animals or make friends with them as they should, and that this attitude must change.

3. Theme

The lesson teaches that animals have a God-given instinct that is quicker than human reasoning in sensing danger, and that we should care for, befriend and respect animals.
