“Where did they learn to ride like that?” she gasped to Valerie.

“On the western plains,” Valerie laughed. “We spent a summer there. Janet has been bursting to show you.”

“Look at them go!” Gloria cried. “They really are good.”

“On flat roads, yes,” Madge smiled. “Let them come to a jump—and watch out.”

“Let’s catch them,” Gale proposed.

An acquiescent nod from the instructor with a word of caution, and the Adventure Girls with Ricky were off in pursuit of their friends.

Carol and Janet were racing neck and neck down the road. They were trying recklessly to outrun one another. Their horses seemed to enter into the spirit of the occasion and raced ahead. The girls bent low in the saddles. They had not had so much fun since they were in Arizona.

“Race you to the old mill,” Janet shouted.

“Be there ahead of you,” retorted Carol.

Around a bend in the road ahead there was an old deserted water mill. Its water wheel was still now and the stream from which it had once secured current was a mere trickle of water through the woods. The girls had discovered the old mill on one of their jaunts about the countryside. Now Janet and Carol decided it would be a good spot at which to bring to a close their race.
