agree in their accounts of what happened. The reporter must judge of the value of the testimony of each witness, and must make up a composite account of the truth as he sees it in these different narratives. The copy-reader, in editing the reporter's story, frequently finds it necessary to cut it down considerably because of the importance of other news.

The chances of printing inaccurate statements under such conditions may be reduced to a minimum only by the exercise of the greatest possible care on the part of all those concerned in the rapid production of newspapers, but mistakes of this type can never be entirely eliminated.
