The chart is drawn for midsummer and midwinter day on the 40th degree of north latitude, which is taken as the best average line that runs midway of the country from ocean to ocean, passing through or near New York City (N); Philadelphia, Pa; Columbus and Cincinnati (S), Ohio; Indianapolis, Ind. (S); Springfield, Ill. (S); St. Louis and Kansas City, Mo. (S); the northern boundary of Kansas; Denver, Colo. (S); Salt Lake City, Utah (N); Carson City, Nev. (S); and Sacramento, Calif. (S). With the exception of St. Louis and Sacramento, which are something over a degree south of this line, all of these places are either on it or within less than a degree of it, north or south.

You will see, as drawn on the chart, how the sun’s rays morning and evening, summer and winter, are indicated streaming out in the direction of the latitude arrows marked 40°. If you live on or near any of the other degrees of latitude, indicated by the other arrows, imagine the center of the sun slipped up or down to that point, and then trace the rays lightly with a soft pencil across the chart in lines parallel with the respective arrows.

Of course, if you make any change, all four suns must be moved in a corresponding way, for you will observe how beautifully symmetrical the chart is. For any given northern latitude, the midsummer sun rises and sets north of due east and west at exactly corresponding points on the eastern and western horizons, and these points in turn exactly correspond, six months later, with those for midwinter day south of due east and west.
And this exact correspondence east and west, for the day, and north and south, for the season, will obtain for any day in the year, or for any place you take on the earth’s surface. Of course, it must be noted that the time of rising and setting will change with every new position taken. If you draw the midsummer sun down and the midwinter sun correspondingly up until they coalesce at “E” and “W,” you have the equinoxes about March 21st and September 21st, with the sun rising and setting due east and west, and equal day and night in any part of the world except the poles.
