Visual Education (Jan-Nov 1920)

\> Visual Education gion; routes of ocean commerce with their exports and imports; lines of inland transportation; relief and vegetation maps; product maps; rainfall maps; maps of geographical explorations; aeroplane drawings of cities and their surroundings— to say nothing of the hundreds of carefully chosen pictures. Each illustration carries its own story; becomes a living thing. Nor is geography a science sufficient unto itself. It is linked very closely to others. Human history develops where geographical conditions permit, and the connection between natural conditions and the history of settlements is strikingly clear. Here is a text bringing European history up to date: maps show settled and unsettled boundaries, territory controlled by the League of Nations, etc. Certain refreshing departures from traditional textbook practices are evident. The usual sequence in the treatment of continents is not observed: Africa is interposed between Europe and Asia; Polar regions are treated separately as natural units. The last section of the text devotes itself to "The United States — a World Power," bringing out, in the light of the child's knowledge of other countries and peoples, our relationship to them. Finally, the quality of the printing — paper stock, type selections, half-tones and color work — is beyond criticism. The book is a product of art as well as scholarship. To anyone privileged to know the Atwood text, the words on the title page become more than an empty statement: "A New World Lies Before Us." • • * THE MOTION PICTURE HANDBOOK F. H. Richardson Published by the Moving Picture World, New York City, Distributed by the Movie Supply Co., Chicago, III. Such a book as this is needed by those in charge of selecting and installing new projection equipment, or maintaining equipment already in operation, and it is of especial value to every operator occupied with the handling and care of the machines. It is a complete work for study and reference, notable for its clear definitions and descriptions, and is written in a readable style free from cumbrous technical language. The principles of electricity and electrical equipment, the mechanics of projection for both stereopticon and motion pictures, problems of the auditorium — such as arrangement, heating, lighting, ventilation, seating, booth-construction, etc. — every phase of the question is accurately and exhaustively covered. Constant revisions in the course of three editions have brought the manual to the point of completeness and thorough reliability. Lavish illustration by diagrams and photographs, and an adequate index, are features that make for still greater interest and usability and leave nothing to be desired in this valuable book. ,•'•.• MOTION PICTURE ELECTRICITY J. H. Hallberg Published by The Moving Picture World. This is a technical book of great value for any operator whose ambition is not content when he has learned the mere externals of his business. A study of this authoritative manual will enable the operator to handle his machines with ready understanding of the underlying principles and with intelligent appreciation of what is really going on. Motion Picture Electricity is a thorough treatise in reasonable compass. All problems confronting an operator are fully discussed — elemental principles of electricity, wiring, carbon setting, current control, etc.. — as well as the use of the various units of equipment necessary to this work. Extensive reference tables are a large feature of the book. A reference index puts all this material within immediate reach.
