At the end of year or course, a re-showing of the six reels together affords a stimulating review of the whole study. The >ix unit reels have the following titles and contents. Seeing the Sun i Reel 1 ) Airplane views of Mount Wilson and its great observatory open the reel. Then the Sun at total eclipse with the magnificent Corona, the gaseous envelope, the chromosphere. The prom- inences are shown in amazing detail, their vastness, their swiftness of motion, their relation the sun Spots, which, in turn, show clearly the Sun's rotation. lining to the Moon (Reel 2) From the interior views of tin- Mount Wilson ( Miservatory we glance tt|> at the Moon with naked eye and. by skillful illusion of the camera, we travel toward it. Its size grows. Surface details appear. Then an excursion hack and forth over the whole side of the moon visihle to us. viewing its monstrous craters, mountain ranges, walled plains, its dead "seas." and numerous spots bearing names of famous features upon the earth. Prom Mercury to Mars (Reel 3) The inner planetary group, with asteroids and comets, are covered in this reel The nature of Venus, the rotation of Mais, his surface markings and change of seasons; the course of a comet, the method of discovering an asteroid. Jupiter. Saturn and Beyond ( Reel 4) From the Lowell Observatory in Arizona we study Jupiter, his changing belts and moons; the rings of Saturn, their shifting appearance as his revolution around the Sun changes our angle of view, and his Great White Spot of 1933. Uranus and his satellites. Neptune and his single moon, and finally Pluto and how he was discovered—bringing us to the miter fringe of our little solar system. The Pathway of the Gods | Reel 5) From Yerkes Observatory in Wisconsin we see the Milky Way. Galaxies, star clouds, clusters, nebulae of both spiral and ring formations, double stars, new stars, their birth and growth within a few short years. The Depths of Space (Reel 6) And now out to the other stellar systems, with a new yard stick of hundreds of thousands of light years, among such marvels as The Great Nebula of Andromeda, the beautiful spiral of Triangulum, the Coma Virgo region, and still further out to clusters of island universes where we must talk of fifty million light years and more. The six silent reels contain a vast amount of material for the eye; material for the ear that may accompany the rich spectacle is simply unlimited. Teacher or lecturer alike will be faced by one prob- lem only, "what to omit"—never "what to say." (Accompanying manuals for teacher and lecturer supply a wealth of material and explanation).
