“Oh, my goodness!” cried Amy. “Now I understand. Billy Foley is to have a birthday party.”

“That’s what I said,” declared Henrietta complacently. “And Mrs. Foley says if you two young ladies was to come it would please her highly.”

It was evident that the invitation was couched very nearly in Mrs. Foley’s own words. Jessie and Amy looked at each other and by eye-signal agreed.

“Of course we will come, Henrietta,” said Jessie. “And we are very glad that Mrs. Foley thought of us.”

CHAPTER XVIII
BILLY’S BIRTHDAY

Darry and Burd had towed in the Water Thrush while the girls had gone to Stratfordtown with Mrs. Norwood; but they were so busy caulking the seams and repainting the launch that Jessie and Amy could not look to the young collegians for any companionship that afternoon.

“And we musn’t annoy them—the way Belle and Sally Moon do,” said Jessie.

“I like that! My own brother,” sniffed Amy. “He needn’t think he’s so big just because he goes to Yale.”

“We don’t want to get snubbed, do we?” laughed her chum. “Come on, honey. I’ve an errand down at Brill’s. He’s got a new kind of a test-buzzer, and I want to try it, and buy one if it is better than our old one. You know, Brill has got a set in working order and you can listen in down there just as though you were at home here.”

“Goody!” proclaimed Amy. “I was just feeling like a George Washington sundae.”
