Once a big bateau went drifting by and disappeared behind Gannet Island, under a lazy sail and with two men at the long sweeps, or oars. When it was lost to view Wyn was troubled by the thought that it might be the same mysterious craft that had followed the catboat the night before. Had it anchored off the boys' camp now? So, to calm her own mind, she suggested that they all paddle over to Cave-in-the-Wood Camp and take their luncheon with them. "Goodness me, Wynifred!" exclaimed Bess, the boy-despiser, "can't you keep away from those boys for a single day?" "I notice we usually have a good time when the boys are around," returned Wyn, cheerfully. "Oh, they're quite a 'necessary evil,'" drawled Frank. "But I feel myself like Johnny Bloom's aunt when we get rid of the Busters for a time." "What about Johnny's aunt?" queried Mina. "Why, do you know that Johnny belongs to the Scouts and one law of the Scouts is that they shall each do something for somebody each day to make the said somebody happy." "Rather involved in your English, Miss, but we understand you," said Grace. "So far," agreed Percy Havel. "But where do Johnny Bloom and his aunt come in?" "Why, any day he can't think of any other kindness to render his friends," chuckled Frankie, "he goes to see his aunt. She is so glad when he goes home again--she detests boys--that Johnny feels all the thrill of having performed a good deed." "Now, Frank!" laughed Wyn, "you know it isn't as bad as all _that_." "Yes, it is," chuckled Frankie. "You don't know Johnny Bloom as well as his neighbors do. He lives on my street." "Humph! most boys are just as bad," declared Bess. "Just the same, if Wyn says 'Gannet Island' I reckon we'll all have to go." "And we'll have some fun diving," Grace Hedges declared. "I wish we had a diving float over here." Mrs. Havel preferred to remain at the camp and the six girls were a very hilarious party as they set forth in their canoes and fresh bathing suits for the island. By this time every member of the Go-Ahead Club was as brown as a berry, inured to exposure in the sun, and enjoying the outdoor life of woods and lake to the full. Mina's timidity had worn off, Percy was not so "finicky" in her tastes, Bessie was more careful of other people's feelings, Grace really seemed almost cured of laziness, Frank was by no means so hoydenish as she once was, and as for Wynifred, she was just as hearty and happy as it seemed a girl could be. Their independent, busy life on Green Knoll was doing them all a world of good. As the little squadron of canoes drew near to the easterly end of the Island the girls were suddenly excited by a great disturbance in the bushes on the hill above them. This end of the island was exceedingly steep and rocky. "Oh, what's that?" cried Mina, as some object flashed into view for a moment and then disappeared. "It's one of the goats," squealed Frankie.
