When Mr. Porter heard of the new trouble at the hands of Lem and Dolly, he said they had no right to be there, for it was his ground, and he should see it did not happen again, for he would not have his boarders disturbed. He told Colonel Rush they had better take the house-dog, old Buffer, with them the next Sunday, and let him watch on the rocks above, so that no one could come near. Buffer was a wise dog, and if put on guard, he would not leave his post till he was told he might; so now the children felt they would be safe in their "Sunday bower," as they called the cleft in the rock.
