What Makes the Sky Blue.

If there was no dust haze above us the sky would be black. That is, wewould be looking into the blackness of a limitless space. When in fine, clear weather we have a deep, rich, blue above us it is caused by a haze.. The particles in the haze of the heavens correspond with those of the tube in the koniscope, and the blue color is caused by ttye light shining through a depth of fine haze. — [Science.
