SPACE NOT VACANT

The idea that the vast spaces between the sun and the various

planets are void and untenanted now belongs only to the history

of science. To-day it is known that these spaces are filled

with vast swarms of minute, dust-like bodies, each and every

one revolving about the sun in vast ellipses, each one being,

in fact, a microscopic planet. These bodies make their presence

known not only as meteors or shooting-stars, but also by their

power to reflect sunlight, and thus produce the peculiar evening

glow of the zodiacal light.--CHARLES LANE POOR, “The

Solar System.”
