I was not a pilgrim, but an engineer attache to an expedition through Dakota and Montana, to inspect some new military posts.  The expedition consisted, where the Indians preserved the peace, of the late General W.B.  Hazen, myself, a cook and a teamster; elsewhere we had an escort of cavalry.  My duty, as I was given to understand it, was to amuse the general and other large game, make myself as comfortable as possible without too much discomfort to others, and when in an unknown country survey and map our route for the benefit of those who might come after.  The posts which the general was to inspect had recently been established along a military road, one end of which was at the North Platte and the other—­there was no other end; up about Fort C.F.  Smith at the foot of the Big-Horn Mountains the road became a buffalo trail and was lost in the weeds.  But it was a useful road, for by leaving it before going too far one could reach a place near the headwaters of the Yellowstone, where the National Park is now.

By a master stroke of military humor we were ordered to return (to Washington) via Salt Lake City, San Francisco and Panama.  I obeyed until I got as far as San Francisco, where, finding myself appointed to a second lieutenancy in the Regular Army, ingratitude, more strong than traitors’ arms, quite vanquished me:  I resigned, parted from Hazen more in sorrow than in anger and remained in California.

I have thought since that this may have been a youthful error:  the Government probably meant no harm, and if I had served long enough I might have become a captain.  In time, if I lived, I should naturally have become the senior captain of the Army; and then if there were another war and any of the field officers did me the favor to paunch a bullet I should become the junior major, certain of another step upward as soon as a number of my superiors equal to the whole number of majors should be killed, resign or die of old age—­enchanting prospect!  But I am getting a long way off the trail.

It was near Fort C.F.  Smith that we found our first buffaloes, and abundant they were.  We had to guard our camp at night with fire and sword to keep them from biting us as they grazed.  Actually one of them half-scalped a teamster as he lay dreaming of home with his long fair hair commingled with the toothsome grass.  His utterances as the well-meaning beast lifted him from the ground and tried to shake the earth from his roots were neither wise nor sweet, but they made a profound impression on the herd, which, arching its multitude of tails, absented itself to pastures new like an army with banners.
