as shown in Fig. 2, should be used. The patterns or the detail should be of larger size so that they will be clearly visible on the television receiver screen.
II— KINESCOPE PHOTOGRAPHY.
A recent development in television has been the perfection of cameras that photograph the image on the picture tube and simultaneously record the sound. This process is known as ki teletranscribing " or 4t Kinescope recording," and is a step forward in creating a nation-wide network without the use of a coaxial cable or of microwave links. The teletranscription method of networking permits television stations in the smaller-populated centres to carry top-quality metropolitan programmes at a cost commensurate with their operational budget. At the same time, the advertiser is enabled to procure nation-wide coverage of all markets with his television programme. The
films can also be used in sales promotion and demonstration rooms of retail dealers for sales promotion and entertainment. These films can be used to protect the station owner and the advertiser in case of litigation ; such films are not, at present, * required by the Federal Communication Commission in the United States.

Owing to the four different time zones in the United States, coaxial cable or radio relay network between the east and west coasts is not a complete solution to the problem of nation-wide coverage with a network programme. For example, a television programme originating in the Los Angeles area at 10.00 p.m., Pacific Standard Time, transmitted to New York City over a network circuit and broadcast there simultaneously, would enjoy a very small audience since the time in New York City would be 1.00 a.m., Eastern Standard Time. When this programme is recorded on motion picture film by Kinescope photography and shipped to New York City, the show can be televised in that area at a more propitious hour.
Another use for Kinescope photography is in theatre television programmes, where news and special events are transmitted to the theatre, recorded on film, rapidly processed, and projected, either immediately or as a neWsreel after the feature picture. This method of theatre television enables the theatre management to present and plan their programmes without interruption and discontinuity.
