“But two whole days,” Roger muttered, “they will seem ever so long to me, Dick. I wish it could be to-morrow.”

“Oh! but there is plenty to be done, for all of us,” replied the more thoughtful lad; “I’ll see to it that you have no idle minutes on your hands from this time out. To begin with, Roger, pick up your tools, and bring them to the house. All work on this boat must be put off until our return, unless Sam chooses, with the help of Grandfather, to finish it, which I rather think will be the case.”

They turned their back upon the river, but it would be in their minds always. Indeed, they must expect to follow its erratic course over plains and through valleys, heading into the northwest continually, until in due time they might hope to overtake those who had gone before, with horses, and boats, and all manner of stores, intended to placate, it might be, the hostile and suspicious tribes that had never before set eyes on a white man.

Yes, those were busy hours with every one. Even Sam felt that he must do what little he could. The hunting could wait until after his brother had said his last good-by, and ridden away into the west—time enough for all that; but just now he wanted to see all he could of Dick, who had never seemed half so dear as when he was about to go away.

Sad hours they were for the parents of both lads, though they endeavored to conceal it. The mothers shed their tears in secret, not wishing to display any weakness. Now that the matter had been settled they were like the staunch Roman mothers of old, who could with dry eyes send their sons forth to battle, keeping all display of womanly weakness for their own rooms.

The horses that were to be taken had been selected, and every detail of saddles and bridles looked after before the first full day had gone. Bob and Sandy Armstrong saw to these things themselves. Their former experience in the forest was of great value in this emergency, for they knew just what ought to be taken by their sons, from extra flints in order to ensure fire, and for the rifles, to blankets needed on the nights when perhaps they would be exposed to chilling winds and storms, far up in a mountainous country.

By the time the next day was over, the preparations had gone on so well that the boys had gained the consent of their parents to making the start at noon of the following day, which would give them several hours’ gain on the original plan of campaign.

Charts or plans of the country there were none, for no whites had penetrated more than a hundred miles or so to the westward. It was believed that many different tribes of Indians lived along the upper Missouri, for from time to time venturesome trappers had met roving bands and picked up a certain amount of information concerning the fierce Sioux, the Blackfeet, the Mandans, and other nations that warred against each other, and seemed to hold certain sections of the country as their hunting grounds, ready to fight any trespassers, be they red or white.

Roger had gone down to the settlement of St. Louis to carry out some errand entrusted to him, and on his return it was seen that the boy looked very much excited, as though he might have heard news that concerned the mission he and his cousin had agreed to carry out.

The others were gathered at the cabin of Grandfather Armstrong, examining something which the old man had brought out, and which he wished the boys to take along with them on their trip.
