"What doing?" asked Bobby.
But Celia shook her head dolefully.
"Come, let's go walk somewhere and I'll tell you," said she.
They crossed Main Street to the shaded street on which lived Georgie Cathcart.
"What is it?" demanded Bobby again.
"We are going home to-morrow," Celia announced mournfully. "Mamma has a letter."
Bobby stopped short.
"Going home!" he echoed.
"Yes," said Celia.
"Then we won't see each other till next summer!" he cried.
