How does the author use foreshadowing in Summer of the Monkeys?

In Chapters Thirteen through Fifteen, the author presents the conclusion to the major conflict in the narrative—Jay Berry catches the monkeys but not in the way he expected to. Several events foreshadow his success. First, the storm appears to be almost supernatural in intensity and Daisy claims The Old Man of the Mountain appears and grants the house good luck. Later, Daisy finds a fairy ring the family heralds as a supernatural token of luck. Lastly, Jay Berry makes a wish..... not for a pony and a rifle, but that his little sister's leg can become healed. Daisy wishes that Jay Berry could get a pony and a rifle. Rowdy apparently wishes that Rowdy can get a big bone—all three wishes come true. Mama and Papa also wish that Daisy's leg can be healed. Jay Berry's reward money will empower him to insure his sister will have her operation.
