mONIGHT Mr. Valentine will describe some of the most famous country in Great Britain-the wild and rugged Highlands at their most accessible point. The lofty mountains. the purple glens and silver lochs of the Highlands stretch Northward for another hundred miles, but the part with which he will deal is the northern half of Perthshire, within easy reach of Edinburgh (first stop from London now), with the Cairngorms. Aviemore, Loch Rannoch, Killiecrankie and the wonderful scenery of Speyside.
