Hi Doncontrols. Brig had square sails on both masts. Topsail schooner was fore-and-aft rigged with squaresails on foretopmast ie with yards as on "Beatrice".
I wondered if the glass plate had a note describing "Beatrice" as a brig. Some brigs were rerigged since fewer crew required to handle sails on a schooner.There are quite a few schooners etc named "Beatrice" in the Mercantile Navy List around 1900 so it would not be easy to pin her down. Lovely photo by the way.
