for some time, as it could not run out
or soak down through the clay. Bunny and Sue were allowed to go to the
clay-pond because it was not deep, and not far away. But Mrs. Brown
always told them to be careful not to slip down in the wet and sticky
clay or muddy water.

So now, with the net and the tin can to catch frogs, away the two
children started. They had not been frog-hunting since Aunt Lu went back
to New York.

"There ought to be lots of frogs now," said Bunny.

"Yes," agreed Sue. "I hear them singing every night."

"Frogs don't sing!" her brother said.

"Yes they do too!"

"No they don't!"

"Then what do they do?" Sue wanted to know.

"They croak!" said Bunny. "Frogs can't sing, they just croak."

"Well, they can hop then!" Sue was sure of that. "'Cause the ones
George Watson let loose at our party hopped."

"Oh, yes, frogs can hop," Bunny knew that well enough.

"All 'ceptin' pollywoggles," went on Sue. "They jest wiggle."

"That's right," said her brother. "Pollywogs can't hop, 'cause they've
got no legs. Come on."

The two children were soon at the frog pond. They could hear the frogs
croaking, or "singing," whichever you call it, and with his net Bunny
was soon scooping around in the water, to catch some of the hopping,
swimming creatures.

"Oh, I've got a big one!" the little boy suddenly cried, as he lifted
the net into the air. "Where's your can, Sue?"

"Here it is, Bunny!"

Sue held up an old tomato can, with the cover off, while her brother
turned his net upside down over it. Some black mud and water splashed
from Bunny's net, some splattering on Sue's dress. She looked eagerly
into the can.

"There isn't any frog at all, Bunny!" she exclaimed, much disappointed.

"No frog?" shouted Bunny. "Of course there is!"

With a stick he poked in the mud on the bottom of the can. No frog was
there.

"Well, he must have hopped out," he said.

"Maybe you didn't have one, Bunny."

"Yes I did. But he got away. He was a big one, too. But I'll get
another."

A little later Bunny did catch two frogs, though they were small ones.
He put them in Sue's can. She looked at them for a while and then asked:

"Oh, Bunny, oughtn't I to put some water in the can, so the frogs can
swim? They won't like us if we don't let them swim."

"Well, put a little water in," said Bunny.

With the frogs in the can, Sue dipped it into the pond, at the water's
edge. Then she gave a sorrowful cry.

"Oh, Bun
