Doctor Stevens ran across from his home.

“Better close all your windows and secure the doors,” he warned. “We’re going to get a lot of wind before the rain comes.”

“Tom is afraid of a tornado,” said Mrs. Blair.

“The weather is about right,” admitted the doctor. “But we won’t worry until we see the clouds start to swirl. Then we’ll run for the storm cellar under my house.”

Helen and Margaret hurried to help Mrs. Blair close the upstairs windows while Tom went around to make sure that the screens were secure. He bolted all doors except the one to the porch and when he returned to join the others, the tempo of the wind was increasing rapidly.

The wind suddenly dropped to a whisper and Doctor Stevens watched the rolling clouds with renewed anxiety. The waters of the lake were calmer and the dust clouds which the wind had driven over the water cleared partially.

“Look!” cried Helen. “There’s a motorboat trying to reach one of the boathouses here!”

Through the haze of dust which still hung over the lake they could discern the outline of a boat, laboring to reach the safety of the Rolfe end of the lake.

“It’s Jim Preston,” said Doctor Stevens. “He goes down to the summer resorts at the far end of the lake every Sunday morning with the mail and papers.”

“His boat’s got a lot of water in it from the way it is riding,” added Tom. “If the storm hits him he’ll never make it.”
