reach of his influence, and infused an entirely new spirit into the cultivators of the soil. From being one of the most inaccessible districts of the north—the very _ultima Thule_ of civilization—Caithness became a pattern county for its roads, its agriculture, and its fisheries. In Sinclair’s youth, the post was carried by a runner only once a week, and the young baronet then declared that he would never rest till a coach drove daily to Thurso. The people of the neighbourhood could not believe in any such thing, and it became a proverb in the county to say of an utterly impossible scheme, “Ou, ay, that will come to pass when Sir John sees the daily mail at Thurso!” But Sir John lived to see his dream realized, and the daily mail established to Thurso. The circle of his benevolent operation gradually widened. Observing the serious deterioration which had taken place in the quality of British wool,—one of the staple commodities of the country,—he forthwith, though but a private and little-known country gentleman, devoted himself to its improvement. By his personal exertions he established the British Wool Society for the purpose, and himself led the way to practical improvement by importing 800 sheep from all countries, at his own expense. The result was, the introduction into Scotland of the celebrated Cheviot breed. Sheep farmers scouted the idea of south country flocks being able to thrive in the far north. But Sir John persevered; and in a few years there were not fewer than 300,000 Cheviots diffused over the four northern counties alone. The value of all grazing land was thus enormously increased; and Scotch estates, which before were comparatively worthless, began to yield large rentals.
