Mollie, wringing the water from her skirt. "All we'll have to do will be to toss out the stones, one by one, and the canoe will almost float itself. I can tie a rope to the bow, and we can stand on shore and pull. Those boys will be so glad to get it back."
"But can we lift out the heavy stones?" asked Amy, in considerable doubt.
"Of course we can. You know any object is much lighter in water than out of it, we learned that in physics class, you remember. The water buoys it up. You can move a much heavier stone under water than you could if the same stone was on land. We can all try."
"I never could stay under water long enough to get out even one stone," declared Grace.
"Nor I," added Amy.
"I'll try," spoke Betty—she was always willing to try—"but I'm afraid I can't be of much help, Mollie. And I'm sure I don't want you to do it all."
"Well, wait until I make another inspection," said the diving girl. "It may be more than I bargained for. I'll hold my breath longer this time."
"Do be careful!" cautioned Aunt Kate, coming out from the tent.
"We will," promised Betty.
