"Why, didn't you say that you were going over the Oregon Trail this year?" she quickly asked. "At least, I understood you that way."

"I often let my enthusiasm run away with me," he answered. "Much as I would like to go out to Oregon I will have to wait until my affairs will permit me to follow my inclination. You see, I've made two trips to Santa Fe, it has got into my blood, and there are reasons why I must go over that trail again. And then, knowing the trail so well, it is possible that I can make very good arrangements this year. But isn't it a most remarkable coincidence?"

"Very," drily answered the captain. "By the way, Mr. Boyd: you and Mr. Cooper seem to be quite friendly, and neither of you waste much time in the company of your present roommates. Seeing that you are both bunked with strangers, how would it suit you if I put you together in the same room? Good: then I'll speak to Mr. Cooper, and if it's agreeable to him I'll have the change made. Sorry to tear myself away from you two, but I must be leaving now." He bowed and stepped into the cabin, smiling to himself. He distinctly remembered his conversation with the young man, only the day before, when Tom had assured him with great earnestness that he no longer could resist the call of the emigrant trail and that he was going to follow it with the first outgoing caravan. The captain was well pleased by the change in the young man's plans, for he knew that the niece of his old friend would be safer on her long journey across the plains if Tom Boyd was a member of the caravan. He turned his steps toward the gaming tables to find her uncle, whom he expected would be surrounded by the members of a profession which Joe Cooper had forsaken many years before for a more reputable means of earning a living.

The reputation of "St. Louis Joe" was known to almost everyone but his niece; and the ex-gambler was none too sure that she did not know it. While his name was well-known, there were large numbers of gamblers on both rivers, newcomers to the streams, who did not know him by sight; and it was his delight to play the part of an innocent and unsuspecting merchant and watch them try to fleece him. Not one of the professionals on the Missouri Belle knew he was playing against a man who could tutor him in the finer points of his chosen art; but by this time they had held a conference or two in a vain attempt to figure why their concerted efforts had borne bitter fruit. One of them, smarting over his moderate, but annoyingly persistent losses, was beginning to get ugly. While his pocketbook was lightly touched, his pride was raw and bleeding. Elias Stevens was known as a quick-tempered man whom it were well not to prod; and Joseph Cooper was prodding him again and again, and appearing to take a quiet but deep satisfaction in the operation. At first Stevens had hungered only for the large sum of money his older adversary had shown openly and carelessly; but now it was becoming secondary, and the desire for revenge burning in Stevens was making him more and more reckless in his play.

The careless way in which Joe Cooper had shown his money to arouse the avarice of the gamblers had awakened quick interest in others outside the fraternity, and other heads were planning other ways of getting possession of it. Two men in particular, believing that the best chance of stealing it was while the owner of it was on the boat, decided to make the attempt on this night. If the boat should remain tied to the bank their escape would be easy; and if it started before daylight they could make use of the yawl, which was towed most of the time, and always during a run after dark.

Captain Newell looked in at the gambling tables and did not see his friend, but as he turned to look about the upper end of the cabin he caught sight of him coming along the deck, and stepped out to wait for him.

"Looking for me?" asked Uncle Joe, smiling.

"Yes; want to tell you that your young friend Boyd has changed his mind and is going out to Santa Fe to look after his numerous interests there. Ordinarily I would keep my mouth shut, but I know his father and the whole family, and no finer people live in St. Louis. Who have you in mind to go in charge of your wagons?"

Uncle Joe scratched his chin reflectively. "Well, I'd thought of Boyd and was kinda sorry he was going out over the other trail. I'll keep my eyes on the scamp. Strikes me he'd take my wagons through for his keep, under the circumstances! He-he-he! Changed his mind, has he? D——d if I blame him; I'd 'a' gone farther'n that, at his age, for a girl like Patience. How about a little nip, for good luck?"

"Not now. How would you like to change sleeping partners?" asked the captain, quickly explaining the matter.
