Chris Jones recently finished a very unusual journey. Our reporter Mary Owen met him at his home in south London and he told her all about the trip.

Reporter: What gave you the idea to travel around India on an elephant, Chris?

Chris: Well, it all started 2 years ago when I was planning a trip to India. I visited a photographic exhibition of elephants and I realized that the only way to travel is on an elephant.

Reporter: What did you do next?

Chris: I flew to New Delhi and started looking for an elephant. I needed an elephant trained to    carry people. I didn’t know anything about elephants, so I asked an expert for help. He taught me how to ride an elephant. He also helped me find an elephant.

Reporter: Can you tell me about the journey?

Chris: Well. I bought a female elephant called Tara for about $ 6000. We set off from New Delhi a week later. We were heading to Sonepur in northern India where there is a big elephant market and I could sell Tara easily. And what a ride! Elephants can travel at about 6 miles an hour and Sonepur was more than 1,200 kim away. The journey took us 64 days!

Reporter: Did you have any problems on your journey?

Chris: Yes, a few. But nothing serious. On the third day, Tara hurt her foot. But that got better quickly. Also there was a log of heavy rain during the first week and we got very wet!

Reporter: What happened when you reached Sonepur?

Chris: My plan was to sell Tara. But by now I was very fond of her. I couldn’t take her back to Britain and I didn’t want to sell her at the market. By chance，I met some people who wanted an elephant for their national park. I knew that Tara would be safe with them, so I gave her to them. I was very sad to say goodbye.
