"Adieu," responded their host.
They quickly reached the end of the alley and hastily glanced out. There was no one in sight, and Ralph, who was ahead, beckoned Alfred to follow. They crossed the street and leaped the fence, then cut across the lot until they reached the road which their late host had suggested.
The sound of horses' hoofs coming from the main street of the town caused both to stop dead still.
"To the fence, Alfred," whispered Ralph, as the horsemen turned the corner.
"Crouch down low and keep quiet," said Alfred.
The Uhlans, for so they were, passed without halting, and the boys breathed a sigh of relief. But what were they going to the north for at this time of the morning? It was over the very route that they intended to take.
"What shall we do now?" asked Ralph.
"Follow them, by all means," replied Alfred.
"Do you think so?" queried Ralph, doubtfully.
