The gestures may be accompanied by descriptive expressions, as among the negroes, or replaced by them, which seems to be the rule among other peoples. The latter practice offers the further advantage of being available in the night-time, when it is necessary to mention a point of time after dark. The Kayans denote the time of day by pointing to the position of the sun, but for morning and evening they also use the expressions ‘when the sun has risen’ or ‘set’[69]. Expressions for the most important divisions, sunrise and sunset (= morning and evening) and noon, are found among all peoples. Even the tribes of Central and Northern Australia have words e. g. for evening and for morning before sunrise[70]. The richness of the terminology however varies exceedingly. The Indians divide the day into three or four rough divisions only. The Seminole of Florida divided up the day by terms descriptive of the positions of the sun in the sky from dawn to sunset[71]: unfortunately we are not told what these words were or how many of them existed. Among the Hopi of Arizona there is every evidence that the time of day was early indicated by the altitude of the sun[72]. The Omahas know no smaller divisions of the day than morning, noon, and afternoon, to which certainly must be added the transitional periods of sunrise and sunset[73]. The Occaneechi of Virginia measure the day by sunrise, noon, and sunset[74]. The Algonquins of the same province mention the three times of the rise, power, and lowering of the sun[75]. Many tribes however had four divisions[76], e. g. the Natchez of Louisiana, who divided the day into four equal parts: half the morning, until noon, half the afternoon, until evening[77]. But there is also a richer terminology, e. g. the Kiowa words for dawn (‘first-light’), sunrise (lit. ‘the-sun-has-come-up’), morning (lit. ‘full-day’), noon, earlier afternoon until about 3 o’clock, late afternoon, evening (lit. ‘first-darkness’)[78]; and in particular among the Statlumh of British Columbia: dawn (‘it-just-comes-day’), early morning (‘just-now-morning’), morning light (‘just-see-things’), full light (‘just-now-day’), sunrise (‘outside-sun’), early morning (midway between sunrise and noon), noon (up till about 2 p. m.), middle of the afternoon, about 4 p. m., ‘three-fourths-of-the-day-have-gone’, ‘sun-sitting-down’, ‘the-sun-gone’,’evening-creeping-up-the-mountain’ (this refers to the line of shadow on the eastern mountains), ‘reached-the-top’, i. e. the line of the shadows, twilight, ‘getting-dark’, night, darkness, pitch dark[79]. Of the Indians of S. America little is reported. ‘The-sun-is-perpendicular’ was the expression for noon on the Orinoco[80]. The Indians of Chile had words for morning twilight, dawn, morning, noon, afternoon, evening, evening twilight, night, and midnight[81].
