 Little Saanich, Victoria, B.C., which has a 72-inch mirror. A telescope in which the light rays pass through a series of lenses fixed in a long tube pointed directly at the object is called a refracting telescope. The Yerkes telescope at the University of Chicago is an unusually fine 40-inch refractor.

With the greatest of telescopes the moon may be brought to within 60 miles of the earth and a lunar object a mile or so in diameter is easily discernible. The imagination is entranced. All success to astronomers!
