Read this excerpt from "Rikki-Tikki-Tavi."

"He saved our lives and Teddy's life,” she said to her husband. "Just think, he saved all our lives!”

Rikki-tikki woke up with a jump, for all the mongooses are light sleepers.

"Oh, it's you,” said he. "What are you bothering for? All the cobras are dead; and if they weren't, I'm here.”

Rikki-tikki had a right to be proud of himself; but he did not grow too proud, and he kept that garden as a mongoose should keep it, with tooth and jump and spring and bite, till never a cobra dared show its head inside the walls.
