If you read the old books of natural history, you will find they say that when the mongoose fights the snake and happens to get bitten, he runs off and eats some herb that cures him. That is not true. The victory is only a matter of quickness of eye and quickness of foot, -- snake's blow against mongoose's jump, -- and as no eye can follow the motion of a snake's head when it strikes, that makes things much more wonderful than any magic herb. Rikki-tikki knew he was a young mongoose, and it made him all the more pleased to think that he had managed to escape a blow from behind. It gave him confidence in himself, and when Teddy came running down the path, Rikki-tikki was ready to be petted.
