"It could be—yes."

"One of the gypsies?"

"Oh, I wouldn't say as to that. In fact, I don't believe the gypsies are anywhere around here. The children have that notion in their heads, but I don't believe in it. Perhaps it was a blueberry picker who was lost."

"But if he was lost, and saw our tents, he'd stop and ask to be set on the right road," went on Mrs. Bobbsey. "Besides, blueberries won't be ripe for another week or so, and nobody picks them green."

"No, I suppose not," agreed her husband. "Well, I'm sure I don't know who or what it was, but I saw a dark shadow moving away."

"Shadows can't do any harm."

"No, but it takes some one or something to make a shadow, and I'd like to know what it was. I'll take a look around in the morning," said Mr. Bobbsey. "We don't want Twin Camp spoiled by midnight scares."

"Maybe we'd better get another dog, if Snap doesn't come back," suggested his wife.

"I'll think about that. We can't very well train Whisker to keep watch. Besides, he can't bark," and Mr. Bobbsey laughed as he got back into bed.

There was no more disturbance that night and the twins did not again awaken. Mr. Bobbsey remained awake for a while, but he heard nothing, and he believed that if it was a man or an animal that had brushed against the tent where Freddie was sleeping, whoever, or whatever, it was had gone far away.
