Washington, D.C.: GPO Magazine. Good. Soft cover. pp591-603. Removed from ANNUAL REPORT OF THE BOARD OF REGENTS OF THE SMITHSONIAN INSTITUTION, FOR THE YEAR ENDING JUNE 30, 1899. VG. In plastic report covers. From the introduction: "Twenty years ago, reviewing the progress of the steam engine, to date, and seeking the reasons of the steady gain observable in the economy of its operation, the writer, in his History of the Growth of the Steam Engine, remarked: The direction of improvement has been marked by a continual increase of steam pressure, greater expansion, provision for obtaining dry steam, higher piston speed, careful protection against loss by radiation and conduction, and in marine engines by surface condensation. This statement and the extended discussion of the details of method and manner of steady improvement during the time since Watt, which were then and there given, apply as well today, and require absolutely no qualification, and the summary holds good for the century".
