But there is still another class of news which involves proces-ses of a single event which may or may not arrive at completion.The news in this class records successive stages of a progressiveevent， in which every occurrence and all occurrences from day today， however important in themselves， are but parts of thewhole， steps of a continuing process. An election， for example，is an event which completes a long process of developing events inthe course of the campaign， all contributing to a single result andnever separated from the end to be reached. A political or socialreform movement furnishes news of the same nature， continuousand inseparable， which progresses， or endeavors to progress， toa desired end. A session of congress produces news of a proces-sional nature in which there are many continuing currents of e-vents， currents which may attain completion in achievement orwhich may disappear in the sands， but which in the process pres-ent varied aspects and varied appeals to public interest.
　　Much news， therefore， and， as a rule， the more importantnews， is of a serial character， carrying many continued stories offact， each report a new chapter， each incident a link in a chain.Whether long stories or short they have the attraction of continui-ty， of expectation， often of surprise， promoting and sustaininginterest in the degree in which they touch human emotion andconcern.Each edition of a newspaper is a new creation. And each　day's creation is different from that of any other day.
