Dick would have preferred going on, but did not wish to leave his brother alone, so he also halted.  A buckle had broken and it took some time to repair the damage, so Tom could continue his ride.

“The girls have disappeared,” said Dick, on making the turn ahead in the road.

They came to a spot where the road divided into three forks and halted in perplexity.

“Well, this is a nuisance,” declared Tom, after scratching his head.  “I suppose they thought we were watching them.”

“More than likely.”

“Which road shall we take?”

“Bless me if I know.”

“Well, we can’t take all three.”

They stared at the hoofprints in the road, but there were too many of them to make anything of the marks.

“Stumped!” remarked Tom, laconically.

“Let us wait a while.  Perhaps, when the girls see we are not following, they will turn back.”

“All right; but we’ve made a fine pair of escorts, haven’t we, Dick?”

“We are not responsible for that buckle breaking.”

“That’s so, too.”

They waited for several minutes, but the girls did not appear.

“Supposing I take to one road and you to the other?” said Dick.  “If you see them, whistle.”

“What about the third road?” And Tom grinned.

“We’ll leave that for the present.”

Off they set, and as ill-luck would have it took the two roads the girls had not traveled.  Each went fully a mile before he thought of coming back.

“Well, what luck?” asked Dick, as he rode up.

“Nothing doing, Dick.”

“Ditto.”

“Then they must have taken to the third road.”

“That’s it,—­unless they rode faster than we did.”

“Shall I try that other road?”

“You can if you wish.  I’ll stay here.  If they come back, we can wait for you,” added the oldest Rover.

Once more Tom set off.  But he had pushed his horse so fast before the animal was now tired and had to take his time in traveling.

The third road led down to the river front, and before a great while the water’s edge was reached.  Here there were numerous bushes and trees and the road turned and ran some distance along the bank.

“Well, I’m stumped and no mistake,” murmured the fun-loving Rover, “I felt sure—­”

He broke off short, for a distance scream had reached his ears.

“Was that Nellie’s voice?” he asked himself, and then strained his ears, for two more screams had reached him.  “Nellie, and Dora too, as sure as fate!” he ejaculated.  “Something has happened to them!  Perhaps those horses are running away!”

He hardly knew how to turn, for the trees and bushes cut off his view upon every side.  He galloped along the road, which followed the windings of the Ohio.  But try his best he could locate neither girls nor horses.

It was maddening, and the cold sweat stood out upon Tom’s forehead.  Something was very much wrong, but what was it?
