 		<meta property="se:production-notes">The PG transcription used uppercase for both italics and small-caps, so each article had to be reviewed to determine which to use. The introduction was brought in from Henry Dawson's edition, and the preface on the text from Henry Cabot Lodge's edition. The transcription apparently used the Lodge edition (a couple of printer errors were in the transcription as well), and the footnotes on the revised text from that edition have been added here, while a couple from the transcription that were not present there were removed. The articles consistently capitalized State(s); this edition lowercases them. The transcription included the author, newspaper, and date of publication for each article; this puts that information in a bridgehead.</meta>
