Their public speaking is only remarkable for applying their whole mind and soul to the business in hand. They state their opinions in a few words to the purpose, using only such metaphor as has a visible bearing on its elucidation. A great deal of the effects of their oratory is due to posture, gesture, and accent. The importance of the subject to them and their undivided attention bestowed upon it at the time is the cause of their forcible remarks. Some of these speeches are excellent in their way, but only so as they illustrate in a condensed form the opinions they wish to express. They are in fact the real children of nature. The prevailing circumstance governs the mind for the time and produces corresponding words and actions. The young and rising no doubt imitate the elders in some of the forms of set speeches but no pains are taken to learn them. TRAVEL When they travel at night and have no moon to afford light they take their direction by the north star with which they are all acquainted, but when stars also are invisible they observe at dark the point from which the wind blows, and shape their course accordingly. By these means they will be able to pursue a right direction until they come to some hill or river with which they are acquainted, and regulate their travel from that point until the sun makes its appearance, and then they are at no loss. Traveling on the plains is much more difficult than in forests. In the terrible snowstorms that sweep over these prairies, darkening the atmosphere and rendering the sun, moon, and stars invisible, or indeed any object a short distance ahead, they are as much at fault to proceed as any other person, and at these times lie down, let the snow drift over and cover them, and remain thus until the storm passes, which is frequently two or three days and nights. There are many ways of determining within a few hours of the time when an encampment has been deserted and the number of persons composing the party. The camp fires will show how many persons have slept there, the dung of the horses or dogs denotes the time, if the fires have become cool. The tracks of the men and animals and the remains of the meal are also means of judging. If scraps of meat or bone seen around are untouched by wolves or ravens they must conclude that the party has recently left.
