For, standing in the doorway of the classroom, which was on the ground floor, was Toby, the Brown's Shetland pony. He stood there looking in, the wind blowing his fluffy mane and forelock, and his bright eyes looking around the classroom as if for a sight of Bunny and his sister.
"Oh, Toby!" cried Bunny. He had spoken out loud in school, but as it was the last day it did not so much matter.
"He came to school, just like Mary's lamb!" exclaimed Charlie Star.
Fat Bobbie Boomer seemed to be forgotten, but the sight of the pony appeared to have brought back to the little boy's mind the line he had missed.
"Which was against the rule!" he suddenly exclaimed.
Every one laughed, even Miss Bradley, and she added:
"Yes, it was against the rule for the lamb to follow Mary to school, and I suppose it's just as much against the rule for the pony to follow Bunny Brown and his sister Sue."
"Please, Teacher, he didn't follow me!" said Bunny.
"Nor me!" added Sue. "We didn't know he was coming! He was in the stable when we came from home."
This was very true, and they were all wondering how it had happened that Toby had followed the children. It was something he had never done before, and, though he was a great pet, he was not exactly Mary's lamb—he did not follow Bunny and Sue everywhere they went.
