James Bowman Lindsay of Dundee, between 1845 and 1854, reinvented and even patented Morse's method, and practically put the plan into operation for experimental purposes across the river Tay.
It is traversed by the Grampian mountains and watered by the Tay, Tummel, Garry, Tilt, Bruar and other streams. Glen Garry and Glen Tilt are the chief glens, and Loch Rannoch and Loch Tummel the principal lakes.
A mile south of Dunkeld, on the left bank of the Tay, is the village of Birnam (pop. 389), where Sir John Everett Millais, the painter, made his summer residence.
