"Well, he wouldn't be the only one to be surprised," spoke Mollie.

"I think we would ourselves," added Betty, with a laugh. "Now, girls, let's see what we really have found."

With a bunch of seaweed Mollie brushed from the box the sand that clung to it. Then the outdoor girls gathered around the case as it rested on the log.

"Look!" exclaimed Grace as the covering of sand was disposed of. "There are some letters on the box."

"So there are!" agreed Betty. They leaned forward to look.

Staring at them from the black top of the box were three white letters. They were rather scratched and faded, but the girls soon made them out as follows:

B. B. B.

"B-B-B," repeated Mollie, as she read them. "I wonder what they stand for?"

"Base-ball-band," said Grace, quickly. "At least that's what Will would say if he were here."

"I wish some of the boys were here," remarked Betty, and again she gave a quick glance out across the bay.
