This is sometimes expressed by different signs to distinguish the sex of animals, when the difference in appearance allows of such varied portraiture. An example is in the signs for the male and female buffalo, given by the Prince of Wied. The former is, "Place the tightly closed hands on both sides of the head, with the fingers forward;" the latter is, "Curve the two forefingers, place them on the sides of the head and move them several times." The short stubby horns of the bull appear to be indicated, and the cow's ears are seen moving, not being covered by the bull's shock mane. Tribes in which the hair of the women is differently arranged from that of men often denote their females by corresponding gesture. In many cases the sex of animals is indicated by the addition of a generic sign for male or female.
TENSE.
While it has been mentioned that there is no inflection of signs to express tense, yet the conception of present, past, and future is gestured without difficulty. A common mode of indicating the present time is by the use of signs for to-day, one of which is, "(1) both hands extended, palms outward; (2) swept slowly forward and to each side, to convey the idea of openness." (Cheyenne II.) This may combine the idea of now with openness, the first part of it resembling the general deaf-mute sign for here or now.
Two signs nearly related together are also reported as expressing the meaning now, at once, viz.: "Forefinger of the right hand extended, upright, &c. (J), is carried upward in front of the right side of the body and above the head so that the extended finger points toward the center of the heavens, and then carried downward in front of the right breast, forefinger still pointing upright." (Dakota I.) "Place the extended index, pointing upward, palm to the left, as high as and before the top of the head; push the hand up and down a slight distance several times, the eyes being directed upward at the time." (Hidatsa I; Kaiowa I; Arikara I; Comanche III; Apache II; Wichita II.)
Time past is not only expressed, but some tribes give a distinct modification to show a short or long time past. The following are examples:
Lately, recently.—Hold the left hand at arm's length, closed, with forefinger only extended and pointing in the direction of the place where the event occurred; then hold the right hand against the right shoulder, closed, but with index extended and pointing in the direction of the left. The hands may be exchanged, the right extended and the left retained, as the case may require for ease in description. (Absaroka I; Shoshoni and Banak I.)
Long ago.—Both hands closed, forefingers extended and straight; pass one hand slowly at arm's length, pointing horizontally, the other against the shoulder or near it, pointing in the same direction as the opposite one. Frequently the tips of the forefingers are placed together, and the hands drawn apart, until they reach the positions described. (Absaroka I; Shoshoni and Banak I.)
The Comanche, Wichita, and other Indians designate a short time ago by placing the tips of the forefinger and thumb of the left hand together, the remaining fingers closed, and holding the hand before the body with forefinger and thumb pointing toward the right shoulder; the index and thumb of the right hand are then similarly held and placed against those of the left, when the hands are slowly drawn apart a short distance. For a long time ago the hands are similarly held, but drawn farther apart. Either of these signs may be and frequently is preceded by those for day, month, or year, when it is desired to convey a definite idea of the time past.
A sign is reported with the abstract idea of future, as follows: "The arms are flexed and hands brought together in front of the body as in type-position (W). The hands are made to move in wave-like motions up and down together and from side to side." (Oto I.) The authority gives the poetical conception of "Floating on the tide of time."
The ordinary mode of expressing future time is, however, by some figurative reference, as the following: Count off fingers, then shut all the fingers of both hands several times, and touch the hair and tent or other white object. (Apache III.) "Many years; when I am old (whitehaired)."
