It is wonderful to contemplate the probability that of some of the more distant stars discovered, the rays of light which have found rest in the eye of the Astronomer, through the aid of the telescope, may have left their native sun thousands of years ago, and travelled at the rate of 192,000 miles a second ever since. "A certain cluster of stars was estimated by Sir William Herschel to be 700 times the distance of a star of the first magnitude--therefore at least 700 times nineteen billions of miles!" But, observes Guillemin, if this cluster was removed to five times its actual distance, that is to say 3,500 times the distance of Sirius, the large Herschelian telescope of 40 feet focus would still show it, _but only as an irresolvable Nebula_. It is, then, extremely probable that, among the many Nebulæ indecomposable into stars, beyond the Milky Way, in the depths of the heavens, many are as distant as that of which we speak. _Doubtless many are more so._ Now to reach us, light-rays must have left stars situated at such a distance more than 700,000 years ago!" Says Child, "When we have touched the verge of this uttermost range, Infinity, boundless as ever, still lies beyond. The idea of God extinguishes in our mind every suspicion that there can be any limit to space, magnitude, or power, in relation to His works. The mighty universe we have been considering is but the stepping-stone to what is farther on; and although our imagination fails to grasp it, our reason assures us it must be so. There is no such thing as taking from or adding to _The Illimitable_. "With what just propriety of thought has light been called the 'voice' of the stars. * * * In the 'speechless' voice of light the stars proclaim to us from the depths of space, the existence of innumerable other worlds which, like our own, share the Creator's care. * * * With mute argument stars prove to us that, in those far-off regions, gravitation--the power that brings the apple to the ground--still reigns supreme, and with suggestive whispers of probability, they persuade us that, like our own Sun, they bathe attendant worlds in floods of light; deck them in colors of beauty, and shower countless blessings on the life of myriads of beings. "Having glanced at the distances and magnitudes of some of the stars, or suns, let us pause for a moment to consider their number, and the vast space they must necessarily occupy in the domain of Creation. By the most moderate estimate the number of stars that can be counted in the firmament by telescopic aid, does not fall short of _one hundred millions_. There is no doubt that most of those stars are _Suns_, dispensing light and heat to earths and planets like our own; and, indeed, no bodies shining by reflected light would be visible at such enormous distances.
