It can equally well be used with artificial lighting conditions when desired. The TRANS-LUX DAYLIGHT SCREEN is non-inflammable, can be cleaned and rolled up without damage. It is made in any size for any purpose. For the sake of finer and more economical projection, ask further details of TRANSLUX PAYLI6HT PICTURE SCREEN* INC , 36WE$T44II!ST, MiW YORK CITY Carl E. Akeley, big game hunter and Curator of the American Museum of Natural History, writes: '• T h e Trans-Lux Daylight Screen is a wonder. . . I am getting infinitely finer projection t li a n I have ever had with any other screen. Because of its brilliancy, much smaller pictures may be used and this feature alone makes a great appeal to me." the bogs, thus not only irrigating the crop but preventing frost injury to the vines. The fourth year after planting, the vines are pruned, and harvest follows shortly after. Experienced labor is required, and only when the bogs are dry can the work be carried on. Especially interesting closeups show the workers raking the berries from the vines with their peculiar basket-scoops. The crop is then screened — to separate the chafif from the berries— and inspected by allowing the berries to bounce on a conveyor; the defective ones being unbounceable, fall to the bottom. Packing in crates prepares for shipment. Keeping Up Railroad Service (2 reels) (New York Central Railroad, Chicago)— A disgruntled shipper, complaining of slow freight service, hears over the radio the story of the progress of railroading in this country. The story, in picture form, begins with the contrast between the first locomotive and the present-day model, followed by a description of many phases of railroad operation, maintenance of way, and replacement of rolling stock. Many interesting glimpses are given of what to many people are little known phases of railroading. In short, the subject is devoted to setting forth facts of railroad operation which may not be apparent to the outsider, but which are really responsible for "making the wheels go 'round." Valuable as a lesson in industrial geography, or as a study in commerce. The Romance of Glass (Atlas Film Co. and De Vry Circulations). — Tradition has it that the discovery of glass was made by the Phoenicians who, setting up a camp on shore, had brought from their ship a block of stone containing crude soda upon which they could cook their meal. The heat melted the soda block, and with the sand on the shore, produced an Please Write to Advertisers and unknown fluid which, when cool, was found to be a new transparent substance. Authentic or not, this little story furnishes an entertaining prologue to an explanation ot modern machine methods of glass making in use today. Molten glass is drawn into the molds by suction — and clear animated drawings show the effect of compressed air in shaping the glass. After the jars are finished, they go to the annealing oven, and are later inspected and counted, capped, packed and crated, ready for shipment. The remainder of the reels deals with the subject of proper canning, and demonstrates the Cold Pack method most clearly and specifically, with several different kinds of food as subjects of the demonstration. (Produced by the Ball Bros. Co.) ENTERTAINMENT Fruits of Faith (3 reels) Pathe. Will Rogers makes possible — almost plausible — the story of a tramp who through faith, the doctrine of which he picked up from a street preacher, came into possession of most of those things, which are considered comfortable assets in this world — a home, goods, a stray child which Fate casts on his doorstep, and a woman to preside over his household. Only by a narrow margin, achieved through the evident sincerity of his acting, does Mr. Rogers save many a scene from the burlesque. In addition, there are some genuinely funny touches. Not that the story is a very real one. The prospector, lost in the desert, meets with an accident, and the donkey, carrying the motherless baby, wanders home to the deserted cabin. The tramp, through the strange workings of faith, comes into possession of the child as weU as the prospector's property', and the father, reappearing some years later, beholds the happy^ Mention The Educational Screen
