"But you must be in by eleven o'clock," he stipulated. "I shall instruct Martin to watch out for you, and if you are not in at that hour it will mean demerits all around. I would not let you go, only you have had very good records of late." On their way to the village the three chums talked of nothing but the proposed trip. To Nat it was enough excitement to think of merely going west. But to Jack, who wanted to solve the mystery of his father it meant much more. He hoped since the eleven years of voluntary exile were almost up, to induce his father to come east and make his home. "That is, if I can find him," thought Jack. "I hope I can. First I'll have to locate Orion Tevis, to see what he knows." "I'll be glad to get out on a range once more," said John Smith. "I've got enough Indian blood in me to feel cooped up in a house. It will be sport out there, riding ponies and seeing the cattle." The boys reached the post-office about nine o'clock and Nat mailed his letter. "It's early to go back," said Jack. "Isn't there something that we can do?" "There's a moving picture show in town," said John. "Let's go to it for awhile." This was voted a good idea. The boys enjoyed the scenes thrown on the screene, and were particularly taken with a depiction of a cowboy roping a steer. "That's what we'll soon see in reality," whispered Nat. They started through the village, and, as they turned down a quiet street that led toward Washington Hall, Jack saw a dark figure sneaking along on the opposite side, in the shadow of some buildings. "Looks as if some one was following us," said Jack to himself. As our hero pulled out his handkerchief there flew out with it a letter. The sight of it reminded him that he had promised Professor Hall to mail it that evening. It had slipped his mind, even though he had been in the post-office. "I'd better run right back with it," said Jack. "Mighty stupid of me. Well, there's no help for it, and I don't want to disappoint Hall. He's a good friend of ours." He picked the letter up, and held it in his hand to insure that it would not be forgotten again. "I say!" called Jack to his companions, who were now some distance ahead of him. "I've got to run back and mail a letter. Go on and I'll catch up to you." "All right," said John. "We'll walk slow." Intent on rectifying his forgetfulness, Jack turned back on the run. He did not see three figures sneaking into the shadow of a dark doorway just as he turned. "We'll have him just where we want him," whispered one of the youths who had been following the students. "You're not going to be three to one, are you?" asked one of the trio. "No, I guess Jerry Chowden is a match for Jack Ranger any day," was the answer. "You two can look on, and see me wallop him."
