makes it possible. Information^" has been published on revocalized films wherein a method is described of redistributing sounds on a phonograph record to bring them into sjaichronism with the picture, or objectionable sections may be eliminated. Bristol has also dealt extensively with a method of re-synchronization of sound.^^
Direction Technic. Very little information of a reliable nature has been published on the technic of directing pictures. Two papers published by leading directors in Hollyw^ood, therefore, are especially valuable, since they recount difficulties and problems encountered under the stress of actual production.®^ A valuable analysis of the director's problems with relation to sound technic has been made by Wm. de Mille.®^
Sound Recording. The making of sound pictures has revolutionized the motion picture industry during the last year. Nearly all the large producers have committed themselves, in part, to a production program and one has announced exclusive production of sound pictures. Four types of sound pictures have been classified by Millikan :®^ (1) musically scored pictures; (2) pictures with songs; (3) news reels; (4) dialogue pictures.
Besides the studios erected by one producer for sound picture production, mentioned previously, ^^ J. A. Ball has reported in a letter to the Chairman of the Committee the installation of 33 recording channels by two companies both for sound on film and wax disc methods. Portable units for recording are being delivered and one picture ' ' In Old Arizona ' ' was taken with portable equipment entirely in open, desert country. Another picture was made in the South Seas with very light portable apparatus; the amplifier unit weighed only 22 pounds and was operated with dry cells, the entire aparatus being transported by canoes.
A historical review of the development of sound pictures has been published. ®° An analysis of E. A. Lauste's early patent specification, granted in 1906, indicates that this inventor had grasped many of the essentials of photographic sound recording as used at the present time.^*^ The variable area sound recording system used by the General Electric Company has been described by Marvin.®^ Wente®^ has reviewed the principles of sound recording and Steinberg^® has discussed the qualities of speech and music.
Besides the use of a glow lamp, variable density records are also produced with a constant light source in conjunction with a slit.
