grass; he ran through the short grass; he ran through the Tropics
of Capricorn and Cancer; he ran till his hind legs ached.

He had to!

Still ran Dingo--Yellow-Dog Dingo--hungrier and hungrier,
grinning like a horse-collar, never getting nearer, never getting
farther; and they came to the Wollgong River.

Now, there wasn't any bridge, and there wasn't any ferry-boat,
and Kangaroo didn't know how to get over; so he stood on his legs
and hopped.

He had to!

He hopped through the Flinders; he hopped through the Cinders; he
hopped through the deserts in the middle of Australia. He hopped
like a Kangaroo.

First he hopped one yard; then he hopped three yards; then he
hopped five yards; his legs growing stronger; his legs growing
longer. He hadn't any time for rest or refreshment, and he wanted
them very much.

Still ran Dingo--Yellow-Dog Dingo--very much bewildered, very
much hungry, and wondering what in the world or out of it made
Old Man Kangaroo hop.

For he hopped like a cricket; like a pea in a saucepan; or a new
rubber ball on a nursery floor.
