Pictorial or other signs are not used in accounts, either by them or the white people. ELEMENTS OF FIGURES.—A single stroke answers for 1 and each additional stroke marks the additional number as far as 100. When a stroke is made apart, the score is rubbed out and begun again. There are no written nor marked records kept, either on graves or otherwise, of ages or of events, scalps taken, or war expeditions.[7] Their transactions, or coups, as they are called in this country, are pictured on their robes, lodges, and shields, but these wearing out are seldom renewed, particularly when the man becomes old. Also these coups are recounted publicly by the performer on occasions appointed for the purpose, which we shall notice hereafter, and moreover, are talked of often enough around their firesides. Ages are numbered by particular events that took place at the time they could first recollect, and afterwards by certain remarkable years from time to time. Though no Indian can be sure as to his exact age, yet he will not vary more than a year or two as to the time. The cross (X) is not used in counting or for any other purpose, neither does the dot or full comma signify a moon or anything else. [7] It is not intended by this that they make no use of picture writing, but that these records are not preserved. For further explanation see picture writing, p. 603. The devices on their robes are not renewed after they have arrived at a very advanced age, or in other words after their influence and standing has been destroyed by age and helplessness. MEDICINE GENERAL PRACTICE.—They are careful of their sick relatives and particularly so in regard to their children or men in the prime of life. Very aged persons do not, however, meet with such kindness even from their own children, having become useless as a help in camp. Besides being a burden in traveling and a bore and expense, they are anxious to get rid of them and leave them on the plains to die. It must, by no means, be inferred from this that the Indian has no paternal feelings or affection; from several instances of the kind that have come under my observation I am assured it is their inability to carry about and along with them aged people. These Indians are poor, have but few horses and are constantly on the move, in all weather, sometimes requiring flight; therefore everything that might encumber in the way of baggage is thrown aside, and among other rubbish is classed the aged of both sexes. I am also told that it is often the desire of the aged to be left to die. To keep up appearances with his people, the Indian will generally pay a small doctor’s bill for the relief of his aged relatives, but nothing like the amount the same man would pay for his wife or child. To explain their mode of practicing medicine, surgery, etc., we must be somewhat prolix.
