"Oh, hurry, Frank, I felt a drop then!" exclaimed Grace. "And there's another! Oh, do hurry!"

The boys worked quickly and in a few moments had raised the tops and were ready to let down the waterproof sides that would make them comfortable in almost any weather.

"We are going to speed up some," Frank shouted to those in the other car. "When the roads get muddy it's going to be pretty hard going, so we want to make good time now."

"Aye, aye, Captain!" Roy answered. "Lead, and we follow."

For a short distance all went well. In fact, the girls rather liked riding in the rain. Then suddenly, without any warning, Frank stopped the car.

"What is it, Frank?" cried Grace in alarm. "Did you run over somebody?"

"No, it's worse than that," he answered gloomily. "Look, the road's closed for repairs!"
