A small spy-glass will reveal large numbers. The stars forming the belt of Orion pointin-the general direction of the first magnitudestar Sirius in the constellation of Canis Major,the Great Dog. Sirius is by far the brightestobject in the heavens if we exclude the sun,moon and planets. It is one of the_ nearestsuns outside our solar system, yet it is so faroff that it takes nearly nine years for its lightto reach us. The diameter of Sirius is abouttwenty times that of the sun and its volumeis about seven thousand times greater. Inthe constellation of Canis Major there are 4-HI (UK COUNTRY AND ITS KKSiil KiKS.

If we followthe line from Aldebaran eastward beyond £wo come t-> the constellation of Gemini, theTwins, marked by the two bright stars,Castr and Pollux; while south of this con-stellation is the first magnitude star Procvonin the constellation of Canis Minor, the LittleDog. It w-ill be noticed that most of tin-constellations so far referred to lie adjacent tothe Milky Way. If we follow the Galaxynorthward, we find just beyond the con-stellation of Auriga, the constellation ofPerseus, whose most interesting star is markedP and u known as Algol, the Demon Star orthe Winking Demon.
