"Grace, you may have to go after them alone to-morrow. Mother objected to letting me go away from her to-day. After this experience I do not think I shall desire to attempt another for some time."

"I shall return to-morrow by way of the shore and may be able to find your collection," said Winslow. "My work will keep me here two or three days longer, and my intention is to go over the beach thoroughly on foot."

"We have already put ourselves under obligation to you beyond our power to repay," said Miss Gaston.

They now were in sight of the little wharf at White Waters, and the red road leading down beside it to the beach which had been followed by the young ladies. On the pier they saw a man and woman walking to and fro, often stopping to look towards the point around which the young ladies were expected to come.

"My poor, dear old mother!" cried Miss Forest, in a burst of excitement, as she caught sight of the two figures. They all set up a cry, and with their handkerchiefs waving soon attracted the attention of their friends.

It was not many minutes before mother and daughter were in each other's arms, as if the younger woman had escaped from some great danger.

"My dear child, how anxious I have been for you, and for you, too, Grace."

"You must thank our escort, Mr. Winslow, mother, for he was a friend indeed, and came along at the right moment."

"I hope you will join us at the hotel this evening, Mr. Winslow," said Mrs. Forest to him as they proceeded up the pier. Miss Gaston was accompanied by the gentleman, whom Winslow observed with interest. Of quiet and easy manner, Mr. Sternly left a doubt in the mind of the young geologist as to what place to assign him in relation to the party whom chance had so suddenly thrown in his way.
