The cab made its way rapidly through the crowded streets, and in a very short time drew up at the Union Depot.
Mark paid the driver, and accompanied by Jack, made his way to the ticket office.
"How soon will there be a train East?" he asked.
"In ten minutes."
"That will suit us, Jack."
He bought tickets, and, the cars being ready, they took their seats in a comfortable car of the Lake Shore and Michigan Railroad.
"If they should come here!" suggested Jack, nervously.
"They would have to run fast, if our train leaves on time. There is no danger, Jack. Even if they suspect that we have left the store, they wouldn't know where we are gone."
Still, even Mark felt relieved and reassured when the signal was given and the long train began to steam out of the depot.
"Wouldn't you like to go back and bid Peggy good-by?" he asked, jocosely.
