still another, and he had landed in it head first, with a great splash.

Of course, when he had seen the cool, sparkling water of the spring, it
had seemed to him that he just couldn't wait another second to get into
it. He was so hot and dry and dreadfully thirsty and uncomfortable! And
so--oh, dear me!--Grandfather Frog didn't look at all before he leaped.
No, Sir, he didn't! He just dived in with a great long jump. Oh, how
good that water felt! For a few minutes he couldn't think of anything
else. It was cooler than the water of the Smiling Pool, because, as you
know, it was a spring. But it felt all the better for that, and
Grandfather Frog just closed his eyes and floated there in pure
happiness.

Presently he opened his eyes to look around. Then he blinked them
rapidly for a minute or so. He rubbed them to make sure that he saw
aright. His heart seemed to sink way, way down towards his toes.
"Chugarum!" exclaimed Grandfather Frog, "Chugarum!" And after that for a
long time he didn't say a word.

You see, it was this way. All around him rose perfectly straight smooth
walls. He could look up and see a little of the blue, blue sky right
overhead and whispering leaves of trees and bushes. Over the edge of the
smooth straight wall grasses were bending. But they were so far above
his head, so dreadfully far! _There wasn't any place to climb out!_
Grandfather Frog was in a prison! He didn't understand it at all, but it
was so.

Of course, Farmer Brown's boy could have told him all about it. A long
time before Farmer Brown himself had found that spring, and because the
water was so clear and cold and pure, he had cleared away all the dirt
and rubbish around it. Then he had knocked the bottom out of a nice
clean barrel and had dug down where the water bubbled up out of the sand
and had set the barrel down in this hole and had filled in the bottom
with clean white sand for the water to bubble up through. About half-way
up the barrel he had cut a little hole for the water to run out as fast
as it bubbled in at the bottom. Of course the water never could fill the
barrel, because when it reached that hole, it ran out. This left a
straight, smooth wall up above, a wall altogether too high for
Grandfather Frog to jump over from the inside.

Poor old Grandfather Frog! He wished more than ever that he never, never
had thought of leaving the Smiling Pool to see the Great World. Round
and round he swam, but he couldn't se
