"Where are the lunch baskets, mamma?"

"Over there behind that tree."

"What is that covered up with that grey blanket?"

"Something Mr. Atkinson brought."

"I didn't see it in our boat. May I peep at it?"

"No, dear, I think I wouldn't. It isn't just the thing to indulge one's curiosity about such matters. Mr. Atkinson had it sent up here, and as he meant it as a sort of a little secret for you children, it wouldn't be polite to try to find it out."

So Dimple with her little maid, walked away, not, however, without several backward looks at the grey blanket.

There was not very much to see on the island, after all, for it was a small place, and the most interesting discovery they made was a pile of big rocks at the upper end of the narrow strip of land. Here they established themselves to watch the boats and the fishers.

"I think Rock has caught a fish," exclaimed Dimple, when she had been watching for some time. "See, Bubbles, he is hauling in his line as fast as he can. There goes the reel again. Oh, I hope if he must catch them, that he will catch big ones. See that lovely red flower growing down there between the rocks. I wish you would get it for me, Bubbles, and then we will go back to where mamma is. I am as hungry as I don't know what, and I want to ask mamma for a turnover or a biscuit or something. Get me the flower, Bubbles, and I'll watch to see if Rock really did catch a fish."

Bubbles promptly obeyed, but she had just stooped to pick the flower when she heard a piercing shriek from Dimple. Mrs. Dallas heard it, too, and came running in the greatest alarm, to find, when she reached the spot, Dimple almost paralyzed with fright, continuing her screams, while Bubbles, dancing about, getting more and more excited every minute, was valiantly hurling pieces of rock at a large black snake.
