The problem has been corrected and as soon as the printer approves the revision, the presses will run. I expect that by next Monday we'll be back in business as usual. For the meantime, I'm holding orders for Nicholson for a few days.
Second off, Michael Stone, a layout carpenter in a professional Broadway scene shop, was reading our edition of Mechanic's Companion (blatant plug here) and discovered an error in the Geometry chapter. Michael's is the first person to point out this problem, which tells me that todays craftspeople are skipping over the Geometry chapter due to a lack of educational preparation in this most necessary of skills. I would like to state, for the record, that I while I failed High School Algebra (yet was graduated anyhow) I did pass geometry, of which I remember nearly nothing.
