First there was a blizzard, then another blizzard (or nearly one), then a collapsed drawing room ceiling led to a last minute cancellation. The net result has been a string of field trip postponements. Ergo, I have only myself to present this week. I am seated on terrace steps at the Braes, Herbert Pratt's former country place at Glen Cove, Long Island. It's a very grand house ('Forget Gatsby,' posted on October 11, 2012) and I was happy that day. Next week: Winterthur, a remarkable building, quite aside from the treasures it contains.
