Ladies and Gentlemen,
    Now we have come to the most exciting and most impressive part of this island trip, The Elephant Walk. If you are interested, you may choose to ride an elephant to have a tour around. All the elephants here are professionally trained for the purpose. Don’t worry if you feel it difficult to climb onto such a gigantic animal; our assistants will be there to help you. Generally speaking, there are four ways to climb onto an elephant. The first is the easiest for the passenger and the most uncomfortable for the elephant. With a command of ’Baitho!’ , the elephant kneels. You climb up to the seat by stepping on the top of the front part of either leg, holding onto the ear, and pulling yourself up. The second way is more difficult. Upon the command of ’Utha! Utha!’, the elephant lifts either of its front legs and, holding onto the ear, you step onto the leg and are raised up as in a lift. The third is over the backside. The elephant lowers one of its back legs and you simply catch hold of the tail. The fourth, the expert’s way, is by the trunk. It looks so elegant and simple. As the trunk is lowered to the ground, you place your foot in the middle and then hold onto both ears. The result is that you are lifted up and over and onto the elephant’s back.
