THE GREAT COMET. Halley's Comet was first telescopically seen on September 11, 1909, in its predicted place, when about 350,000,000 miles distant. In January it will be in Pisces, the fishes, passing the meridian at first at about 7 p. m. and about 10 degrees below the bright stars in the head of the ram. in April and May it will be very beautiful in the eastern morning sky. It will pass on westward to the square of Pegasus and below it, near the prime meridian of the heavens, and by the middle of May it will have moved back eastward to near its old place at the beginning of the year. Its distance from the earth in millions of miles will be as follows: January 1. 127: April 1, 130; May 1, 63; May 10, 33. and May 18. 12. when it may part with some of its matter in the shape of "star dust" which would, of course, fall to the earth.

TRS 11 •Explanation.-The term "Light Year" is the time required for light to travel from these bodies to the earth. Their actual distance, in miles, being too great for use or comprehension, the distance, in miles, may be found by multiplying the velocity of light (183,000 miles per second) by the number of seconds in a year, and that product by the light years. Thus: Alpha Centauri 3.6X183,000 X 365 X 24X60X60 miles distant. THE HORIZON AT SEA LEVEL. The elevations given are in feet.
