sight as soon as she saw it.

All that day valentines were being delivered in various ways. Freddie
found one in his cap, and Bert one between the leaves of his geography.
Flossie found one pinned to her cloak, and Nan received another in a
pasteboard box labeled Breakfast Food. This last was made of paper roses
and was very pretty.

The letter man came that afternoon just as they arrived home from
school. This time he had three valentines for Nan and several for the
others. Some were comical, but the most of them were beautiful and
contained very tender verses. There was much guessing as to who had sent
each.

"I have received just as many as I sent out," said Nan, counting them
over.

"I sent out two more than I received," said Bert.

"Never mind, Bert; boys don't expect so many as girls," answered Nan.

"I'd like to know who sent that mean thing that was marked

But Danny saw him coming, and leaping over the side rail of the piazza,
he ran to the back garden.

"Stop," called Bert. "I know you, Danny Rugg!"

"I ain't Danny Rugg!" shouted Danny in a rough voice. "I'm somebody
else."

He continued to run and Bert made after him. At last Danny reached the
back fence. There was a gate there, but this was kept locked by Sam, so
that tramps might be kept out.

For the moment Danny did not know what to do. Then he caught hold of the
top of the fence and tried to scramble over. But there was a sharp nail
there and on this his jacket caught.

"I've got you now!" exclaimed Bert, and made a clutch for him. But there
followed the sound of ripping cloth and Danny disappeared into the
darkness, wearing a jacket that had a big hole t
