But it seemed as though fate had stepped in to prevent. Sandy had recently been ill, and had hardly recovered his strength; while Bob, only a week before, had cut himself in the foot with an axe, so that he would be hobbling around for a month yet. And, under such conditions, either one of them would prove a drag on the movements of the boys.

And so it was finally decided that the original plan must be adhered to, unless they intended to change their minds entirely, and not allow Dick and Roger to undertake the mission.

The news had the effect of sobering Roger somewhat. He began to realize more than ever that their venture was to be no jaunt, but a serious matter, to call for the best efforts they could put forth. Not only would they be exposed to perils from wild animals, storms that must sweep over the great mountains from time to time, and constantly beset by the hostile Indians whose territory they meant to invade; but here was a new danger in the vindictive and lawless French trader, who would leave no stone unturned to balk the accomplishment of their mission.

Still, neither dreamed of turning back. They were like old Israel Putnam—once his hand was at the plow, nothing could swerve him.

Their friends in the St. Louis settlement proved most kind. Many came out to talk matters over, and some to offer good advice concerning the many difficulties they had heard of in connection with the trail leading to the setting sun. And one and all brought something from their stores that they hoped the boys might find room for among the packages to be fastened on the packhorse.

It had been decided to take only one extra horse along. Dick had been instrumental in bringing about this decision. Although he advanced other reasons, the truth of the matter was that he expected they would have to abandon any pack animal when dangers began to thicken around them, and he did not want to be the means of causing greater loss than was necessary.

Besides, they could carry all they wanted on one animal. There was a rude tent that had seen much use, cooking utensils, blankets, some extra clothing, stores intended for food, and some trinkets that Grandfather Armstrong supplied, such as beads and small looking-glasses, which his experience told him might be used to gain the good will of strange tribes of Indians, to whom such trifles would appeal strongly.

They could not have carried one-quarter of the many articles that well-meaning women friends of their mothers brought with them. This was no junketing expedition, on which they could start with a vast amount of preserves and cakes and such dainties; but a most serious business. They did not disdain to take some of the pemmican, because that might come in handy should they be passing through a dangerous section of country, where it would be risky to discharge a gun, lest by so doing the sound bring a host of enemies upon them.

Dick had listened to all the stories he could concerning the wilderness far up the great river. Then he had gone off by himself, and tried to draw an imaginary chart that would cover the ground. Upon this he had marked all known points; and around any of which there existed any doubt he always drew a circle, to indicate that proof was needed.

No doubt this chart was a crude affair, and, if seen nowadays, when every mile of the distance has been measured and mapped by geographers, it would cause a smile; but, in the absence of anything definite, it gave the boys a certain amount of confidence; and, moreover, as they went along, and certain features were proved to be grossly exaggerated, they could make changes.
