That "upstart with the power to annoy," Montgomery Meigs, aspired to be an architect and ACW blogger Tom Churchill recently took the trouble to visit one of MM's lodges. Great post - but it seems to me what happened in this particular case was that Meigs' Second Empire style home (very contemporary in his day) was subject to a Dutch Colonial makeover, DC being quite popular in the 1920s.
It would really have been interesting to see Meigs' original Second Empire done in stone in that tiny scale Tom photographed - especially with a Mansard roof per the original design.
Good luck to Tom, Stephen McManus, and Donald Thompson over at Touch the Elbow.
(Don't keep touching your elbow, Gen. Halleck, you'll go blind.)
