let Mary Jane
stand in the middle and they sang the song Mary Jane knew so very well,

"I went to visit a friend to-day, She only lives across the way, She said
she couldn't come out to play Because it was her ----"

Quick as a flash Mary Jane dropped onto her knees and began to act out
packing things into a box.

For a minute the children hesitated. That was a strange thing to be
acting; Mary Jane was not washing or ironing or churning or sweeping or
any of the things the children usually acted and they were all puzzled.
Then suddenly Betty remembered the back stairway and all the piles of
boxes and excelsior on Mary Jane's back stairway and she called out the
end of the song--"because it was her moving day!" And everybody finished
the verse with a flourish.

After that Mary Jane felt more at home and the morning went oh, so very
quickly, till recess time, when they all went out into the big yard to

Betty and her particular friends were gathering together for a circle game

close, she couldn't move him either way.

"I'll tell you what let's do," she said. "Mary Jane, you stay here and
guard him so nobody tries to pull him out and I'll go and get Tom and
he'll know what to do." Tom was the janitor.

Mary Jane stood close by the dog and patted his head and talked kindly to
him so he would know somebody was trying to help him. And all the girls
and boys who had started to play together gathered around and watched Mary
Jane while Betty ran back to the school building and down into the
basement to fetch the janitor.

Fortunately, Tom was in his office and came quickly in response to Betty's
call. He saw at once what the trouble wa
