“Just think, mamma, ten whole days!” she cried in despair.

“But the time will pass quickly if you make up your mind to be cheerful,” said Mother Stuart.

“But I cannot go to the picnic to-morrow,” said Lena sadly.  “And just think! it was a picnic that I helped to plan for.”

“But you can watch the children as they play their games on the island,” said Mother Stuart.

“Why, sure enough!” exclaimed Lena.  “I can see them as they cross in Cousin Rob’s boat, right from our front windows.  I hadn’t thought of that.”

Just then a fine black spaniel ran up to Lena and pushed his nose against her hand.

“And I have you, Waggy, to keep me company,” said Lena more cheerfully as she stroked the silky ears of the dog.  “And, mamma, isn’t it lucky that I taught Waggy to go to the post office for the mail and to the market for meat?”

“Very lucky for me,” laughed Mother Stuart.  “That will save me a few extra steps.”

Waggy had learned his lessons well.  When he went to the meat market he always carried a covered tin pail in which to carry home the meat, and when he went to the post office, he was given a big leather wallet in which to carry the letters.

The following afternoon Mrs. Stuart had an engagement with her dentist and was compelled to leave Lena alone with Waggy.  A kind neighbor had lent Lena a wheel-chair so that she could travel from one part of the house to the other.  At two o’clock she began to watch for the picnickers and at last saw them—­five in all—­run down the hill and get into her Cousin Rob’s boat and row out to the pretty island in the middle of the river.  Everyone knew that Cousin Rob was a good boatman and so fathers and mothers did not worry when their sons and daughters went on the water with him.

But on this day Rob was a little careless about pulling the boat up far enough upon the island after all had landed.  While the merry party was on the other side of the island the boat floated away.  Then to make matters worse the sky suddenly became overcast with clouds telling of the storm that was coming.

Lena saw what happened to the boat and presently she saw the five picnickers hurrying toward the spot where they had left the boat.  She could imagine how they felt when they saw their boat floating down stream.

“What can they do!” lamented Lena.  “They will be soaked sure and perhaps the river will rise and sweep them away.”

In hard storms Lena had seen the water rise quickly and hide all of the island except the bushes that grew upon it.

Lena could not telephone for help for there was no telephone in the house.  But she put her mind to work and thought of a way to rescue the castaways.

“Come, Waggy,” she called to her spaniel.  “You must go to the market.”

Lena wrote a message on a piece of paper and put it into the pail which Waggy always carried when he went to the meat market.
