As we traveled on we learned that the wonderful demand for this nervine was in some measure due to the convenient form in which it was sold; and that these bitters were the element frequently used in barter with the Indians, and for which they were ready to exchange their most valued possessions. Some men wonder why the Red Man is at times so insane in his brutality. The uncorking of bottles of bitters of this general type has caused more than one of our protracted wars with the Indians, and a cost of millions of dollars to our Government, a fact that is attested by incontrovertible evidence. There were indeed other and more notable causes of our Indian wars. It must be understood that the savages knew nothing of our national boundaries made by treaty with Great Britain. Some tribes with which we have been at war roamed freely on both sides of that line. Every one of our territories from Wisconsin to the Pacific has furnished scenes of Indian conflicts with the Whites. Yet in some way, Canada has avoided these expensive experiences too terrible to describe. As we follow our vagabond life with the emigrants, and from time to time see the Indians in their various encounters, and dodge the massacres that befall our companions, we hope incidentally to discover some of the reasons why our Government has failed to cope successfully with this problem. CHAPTER VII SOCIETY IN THE WILDERNESS Late in the afternoon of June 18th, when the tin supper dishes had been laid aside and the men were enjoying their after-dinner smoke, the four closely parked groups of wagons, comprising as many camps separated from each other by perhaps a hundred feet in distance, seemed for the time to be in a condition of perfect serenity. The members of each party by itself were quietly awaiting developments. Dan and I strolled out toward the fort, and from a distance watched the movements of mounted men at that post. Soon we observed a long mule train approaching from the east beyond Kearney. It halted for a few moments, and then like a huge serpent it slowly circled round the reservation; and by orders from the guards its wagons were finally corralled beyond our camp.
