No Use for Them AIL.

The asteroids that lie between the orbits of Mars and Jupiter have become so difficult to keep track of, since' they have been discovered at the rate of about twenty a year, that astronomers have recently decided to reject them, excepting the nearest and the most distant. The latter are important in observations of Jupiter, while the nearer ones are useful in more accurate calculations of the earth's dirtance from the sun.
