ly laughed
at him."

"That Danny Rugg is a bad boy," said Nan, severely. But she was soon
to see how much meaner Danny could be.

Workmen had recently finished putting some new water pipes, and a place
for the children to drink, in the school yard, and one morning,
speaking to the whole school, Mr. Tetlow made a little speech, warning
the children not to play with the faucets, and spray the water about,
as some had done, in fun.

"Whoever is caught playing with the faucets in the yard after this will
be severely punished," he said.

As it happened, Flossie and Freddie were not at school that day,
Freddie having a slight sore throat. His mother kept him home, and
Flossie would not go without him. So they did not hear the warning,
and Bert and Nan did not think to tell the smaller children of it.

Two days later Freddie was well enough to go back to class, and Flossie
accompanied him. It was at the morning recess when, as Freddie went to
get a drink at one of the new faucets, Danny saw him. A gleam of
mischief came into the eyes of the school bully.

"Want to see the water squirt, Freddie?" asked Danny. "That's a new
kind of faucet. It squirts awful far."

"Does it?" asked Freddie, innocently. "How do you make it?" He had no
idea it was forbidden fun.

"Just put your thumb over the hole, and turn the water on," directed
Danny. "You, too, Flossie. It won't hurt you."

Danny looked all around, thinking he was unobserved as he gave this bad
advice. Naturally, Freddie and Flossie, being so young, suspected
nothing. They covered the opening of the faucet with their thumbs, and
turned on the water. It spurted in a fine spray, and they laughed in
glee. That they wet each other did not matter.

Danny, seeing the success of his trick, walked off as he saw Mr. Tetlow
coming. The Bobbsey twins were so intent on spurting the water that
they did not observe the principal until he was close to them. Then
they started as he called out sharply:

"Freddie! Flossie! Stop that! You know that it is forbidden! Go to
my office at once and I will come and see you later. You will be
punished for this!"

With tears in their eyes the little twins obeyed. They could not
understand it.

CHAPTER XII

THE CHILDREN'S PARTY

WHEN Mr. Tetlow, a little later, entered his office he found Flossie
and Freddie standing by one of the windows, looking out on the other
children marching to their classrooms. They h
