every man in the camp stand horse-guard in rotation whenever we stop.
Supposing a hundred Pawnees should jump up out of that ravine, all
yelling and flapping their buffalo robes, in the way they do? Why, in
two minutes not a hoof would be in sight." We reminded the captain that
a hundred Pawnees would probably demolish the horse-guard, if he were to
resist their depredations.

"At any rate," pursued the captain, evading the point, "our whole system
is wrong; I'm convinced of it; it is totally unmilitary. Why, the way
we travel, strung out over the prairie for a mile, an enemy might attack

travel together."

"Then," said the captain, "we might be attacked in camp. We've no
sentinels; we camp in disorder; no precautions at all to guard against
surprise. My own convictions are that we ought to camp in a hollow
square, with the fires in the center; and have sentinels, and a regular
