PURE AND REFLECTED LIGHT 
around an eighth of the horizon circle, and 
then perhaps to a sixth of it; or it may mount 
upward in the shape of a fan. Sometimes pale 
yellow is a predominant coloring, and in warm 
weather a rose hue is quite frequently shown. 
If the sky above the horizon is barred or 
streaked with clouds, almost any conceivable 
color may be reflected from them, dependent 
upon the state of the atmosphere and the posi- 
tion of the clouds. Again, if the air is dense 
with vapor or dust, the advance arms of the 
sun may be seen reaching far over the night 
like the silver shafts of an enormous search- 
light. 
These premonitory signs of the coming day 
are often extraordinary in their appearances. 
For instance, in Egypt, during the heated 
season, the dawn is not always the slow steal- 
ing of light along the horizon. On the con- 
trary, a single shaft like the pinion of a wing 
rises upward toward the zenith. In a moment 
another shaft begins rising by its side, and 
then another and another, until the whole half- 
arch of the heavens resembles two spread wings 
poised perpendicularly. These are, I imagine, 
the biblical wings of the morning that fly to 
the uttermost ends of the earth. At other
