Graphic Methods for Presenting Facts

of all the States or districts, so that the totals of different candidates might be easily compared. Thus, in a presidential election, the counting of the number of States for each candidate does not by any means give the whole story. The important thing is the number of electoral votes, and these would be best represented by the bar summary which would take into account the number of electoral votes of each State estimated as won by any candidate. With the combination slide showing, in the form of bars, both a map and estimated totals, any person coming out of the theater to join the election-night crowd could see instantly how the situation stood up to the moment the last slide was colored.

With the election-return method outlined, the concise telegrams in handwriting would still be shown on the screen one by one as the news came in over the wire. A popular appeal to a large crowd can always be made by snappy statements such as "Jones concedes Chicago to Smith", or "California goes for Brown". Instead of holding statements of this kind on the screen until other news could arrive, however, any statement in written words would be taken off as soon as it had been grasped by the crowd and one of the colored maps would be thrown on the screen. Slides with colored maps and colored bars would be used as fillers, to be kept on the screen continuously whenever there were no telegraphic reports to be projected on the screen in written words. It would probably be found desirable, in many cases, to show telegraphic reports in such manner that a map would be thrown on the screen between each two telegraphic reports, and also held on the screen whenever telegraphic reports should not come in fast enough.
