In 1867 he determined to make for himself a haven of refuge against the invading Philistine, and bought some land on Blackdown, above Haslemere, then a secluded corner of England; here 1'Ir (afterwards Sir) James Knowles began to build him a house, ultimately named Aldworth.
On Blackdown, closely screened by plantations, Aldworth, built for Alfred, Lord Tennyson, who died here i 1892.
Leith Hill in the North Downs reaches 965 ft., and Butser Hill in the South Downs 889 ft.; Blackdown and Hindhead, two almost isolated masses of high ground lying between the two ranges of the Downs towards their western extremity, are respectively 918 and 895 ft.
The Blackdown Hills, in south-western Somersetshire and eastern Devonshire, reach 1035 ft.
But the most remarkable plain is that in Somersetshire, enclosed by the Mendips, the Western Downs, Blackdown Hills and the Quantocks and entered by the Parrett and other streams. The midlands, owing to the comparatively slight elevation of the land, are capable of geographical consideration as a plain.
