The Master of Sempill, who has been very prominent in the flying world ever since he joined the R.F.C. in August, 1914, and Mrs. Forbes Sempill have recently completed a tour of the British coastline, including the North of Scotland, in a light seaplane, and this evening they will describe the pleasures of such a trip.
