     Treetops, the hotel in the trees, is famous in the world. Peop1e know little about Kenya, but they know of Treetops. When King George VI died, Princess Elizabeth was staying on the Treetops, and when she

came down from there, "She succeeded him as the queen of the country".

     The hotel is in the middle of the forest, and it shows the pleasure of Africa. When you visit it, you will

be sent into the heart of the forest by hotel buses, and then a guide, with a gun to protect you against big

game, will go with you to the Treetops. Before and after dinner, for the whole night if you wish, you can sit on the corridor(走廊), watching animals come to the water pool. The earliest hotel Treetops was built

round a large tree on the opposite side of the water, but that was destroyed by fire and the new hotel

Treetops, which is built round several trees, is much bigger.

     The dining room at Treetops is small, and the waiters cannot walk round to serve guests, so a clever

"railway service" has been invented. Guests take their food as it passes slowly in front of them, along a line in the center of the table.

     There are many animals around the Treetops. When you visit them, you can see:

     ---Animals and their babies are waiting to greet the guests.

     ---Animals, enjoying the Treetops pool in the daylight.

     ---A long bodied, long ring tailed very active cat-like animal is a special one coming out at night. He

hunts and eats anything he can catch and is very destructive. He lives in the trees at Treetops. He comes

for his food every evening. Do not get too near to him, as his teeth and claws(爪)can do you harm. These animals can be trained and become lovely pets.
