o Betty and the two trotted along side by
side toward the town. Presently they came to a large sign-board
on which pictures of the circus were posted. There Billy spied
himself pictured as trotting along with the monkey riding on his
back and jumping through the paper hoops.

At sight of the monkey Billy got mad, as usual, and before Betty
knew what he was going to do, he ran up to the fence and
commenced trying to butt it down, calling to Betty to come help
kick it over.

They were thus employed when a farmer came along the road and,
seeing them, took out his whip and drove them off.

They ran along before him for a while and then dropped back until
he had passed them. As soon as he had passed, Billy spied on the
back of his wagon a large basket of celery with the tops sticking
out over the edge.

"Look, Betty, look!" cried Billy, pointing his nose in the
direction of the wagon. "Let's follow on behind and eat up his
celery. It will be a good joke on him." And the two scampered
after the farmer and soon caught up, for he was driving slowly;
and he could not see them for the things that were piled up high
behind him.

When the two rascals caught up to the wagon they ate all the
celery they wanted, which was more than half of it, as it was
deliciously juicy and tasted fine. They had had no breakfast
except some dusty grass that grew beside the road.

While they ate the farmer whistled low to himself and planned how
he would sell his celery to the grocery man; and then, with the
money, go to the circus, and see the wonderful astrologer that
was neither goat nor man who was advertised to perform. He little
guessed that the "Wonderful Astrologer" was at that moment eating
up his celery and making it doubtful whether he would have any
left or not.

Billy and Betty were still eating when a dog spied them and ran
out from his yard after them. Billy turned and tried to hook him
but the dog was too quick. He dodged, but in trying to escape
from Billy he got too near Betty's heels and she gave him a kick
in the side that sent him rolling over into the dust, yelping,
and before he could get up Billy helped him up by sticking his
horns under him and tossing him over the fence.

ABOUT.]

The owner of the dog saw this and ran out calling for the farmer
to stop or he would have him arrested for allowing his goat to
hook his dog. The farmer stopped to see what
