New York: Trustees Gas Educational Fund, 1909. Hardcover. xxi, 683p., illustrated primarily with line-drawn diagrams (some rubricated for emphasis, see pp.458-462) and a few fuzzy photos, first edition brownish maroon cloth boards. Bevelled edges with decorative ruling in blind, spine panel gilt-lettered and -ruled. Slightly edgeworn with a little color-loss round cover's margins, front hinge is cracked but holding, only one little old pencilled note directing reader to "Hydraulic Main," an otherwise clean sound copy. We urge somebody out there to send a copy to PG&E, specially the SF peninsula office.
..looks pretty useful, if you're a pick and helve guy, maybe even if you're a back-hoe guy. "Records should be made and kept" (random sample, p.423) "of the size of the main, its distance from the curb and its depth at every point where it is exposed, and these records should also give the locations of every bell exposed in the course of repairs, so that in future it will be easy to see that the holes are driven at the right points to strike the joints."
