Correspondence chiefly concerns Ewart's appointment to the Swiney Lectureship at the British Museum for 1907, the sale of ponies to the Duke of Bedford at Woburn Abbey (and related correspondence with the estate) and the sale of ponies belonging to Alexander McHardy and Lord Arthur Cecil.

Ewart's main publications in this year deal with coat colour in horses, inbreeding in the Barbary Sheep and the common goat and the horse skulls discovered at the Roman fort in Newstead, near Melrose, Scotland.
