Karen Sue Kreutz, Age 8, Of Spokane, Wash., For her question:

Is there really a tree kangaroo?

The kangaroo, as everyone knows, is a famous jumper. And the place to jump, hop and leap is on the ground. But the big kangaroo has a small cousin who hops and leaps through the trees. This tree kangaroo is a furry fellow about two feet long with a tail which is also two feet long. During the day, he sleeps curled up in the branches and at night he comes dorm to eat and drink.

There are tree kangaroos in the forested regions of Queensland, Australia, and more of them in the thick jungles of new guinea. The gentle creatures feed on cedar leaves, ferns and berries.
