Mary married the Reverend William Sandys, Vicar of St. Minver, and died without leaving any family. The other three never married.
Mr. William Praed married Miss Backwell, of Tyringham, in Buckinghamshire, eventually sole heiress to her very opulent family. He represented St. Ives in several Parliaments, and Banbury in one.
Endowed with a strong mind and with an active disposition, Mr. Praed did not confine his public services to the discharge of duties in the House of Commons. To him the nation is mainly indebted for one of the most useful and most successful of our public works—The Grand Junction Canal.
Three extensive chalk ridges issue from the great central nucleus forming Salisbury Plain; the most southern terminates at Beachy-head, constituting what is called the South Downs. The middle range, passing through Hampshire, Surrey, and Kent, extends to Dover, inclosing between them the wealds of Kent and Sussex, with the Hastings sand formation, and the great alluvial deposits of Romney and Pevensey Marshes. The northern range is still more extensive than the other two: this, passing through Buckinghamshire and Bedfordshire, traverses Cambridgeshire and Lincolnshire; then, after being cut through by the Wash, re-appears in Yorkshire, and finally terminates its long course at Flamborough Head. These two latter ranges intercept all water communication between the capital and the interior of England, except by the Thames, which finds its way through the northern ridge of chalk above Reading. Most river navigations beyond the reach of tides, are impeded by shallows in summer, by floods in winter, by artificial rights of mills, drainages, &c., all of which are avoided by the Grand Junction Canal, which, availing itself of cross valleys, and perforating narrow ridges, has opened an inland navigation from the metropolis
to the British Channel, to the Irish Sea, and to the German Ocean.
Mr. William Praed closed his useful and honourable career of life at Trevethow, in Oct. 1833, having completed his eighty-fourth year; and is succeeded by his eldest son, Mr. James Praed, recently elected member for Buckinghamshire, the county in which he principally resides. Mr. Praed married Miss Chaplin, of Lincolnshire, and has several children.
If this distinguished family should now unfortunately be lost to Cornwall, it is curious to remark that, after remaining there much above a century, no permanent connexion has been formed, and not a single relative will be left behind.
Trevethow is by its natural situation one of the finest places in the west of Cornwall. The house looks to the estuary of Hayle, over a park variegated by rising ground and vales; and immediately behind the house stands Trecrobben or Trencroben-hill, crowned by an ancient fortress, corresponding with those described by Dr. Barham in the third volume of the Transactions of the Geological Society of Cornwall; this hill is the last towards the killas formation of a granite district, extending from the Land’s End, and covered with rocks of a magnitude to create strong impressions of grandeur. The house was so much enlarged and decorated by Mr. Humphrey Mackworth Praed, as almost to claim him for its founder; and it is sheltered by trees more numerous and of a larger size than can usually be found in a country unfavourable to their growth.
But the great artificial ornament of this place is its extensive plantations. Mr. Humphrey Mackworth Praed displayed on this comparatively trifling subject, the same acumen which distinguished him in matters of importance, throughout a long life. Having observed a single pinaster fir, the Pinus Pinaster of Linnæus, growing in an exposed situation, and braving the violence of our west wind, Mr.
Praed immediately conjectured that this tree might be rendered available not merely for ornament, but as affording a shelter for better trees; the experiment was immediately tried, and with complete success.
