1st. Spencer Compton Cavendish, Marquis of Hartington, M.P., P.C., LL.D., was born in 1833, and is unmarried. The Marquis was educated at Trinity College, Cambridge, where he graduated as B.A. in 1852, M.A. in 1854, and LL.D. in 1862. He holds at the present time the responsible post of Her Majesty’s Chief Secretary of State for Ireland, and has successively held office as a Lord of the Admiralty, Under-Secretary of State for War, Secretary of State for War, and Postmaster-General, and was attached to Lord Granville’s special mission to Russia. 2nd. The Lady Louisa Caroline Cavendish, born in 1835, and married in 1865 to Admiral the Hon. Francis Egerton, R.N., M.P. for East Derbyshire, son of the first Earl of Ellesmere, by whom she has issue two sons and one daughter. 3rd. Lord Frederick Charles Cavendish, M.P. for the north division of the West Riding of Yorkshire, born in 1836, and married in 1864 to the Hon. Lucy Caroline, daughter of Baron Lyttelton. 4th. Lord Edward Cavendish, late M.P. for East Sussex, born in 1838, and married in 1865 to Emma Elizabeth Lascelles, a maid of honour to the Queen, and granddaughter to the Earl of Harewood, by whom he has issue two sons. His grace is patron of thirty-nine livings, and in Derbyshire alone is lord of forty-six manors. His other seats are:—Hardwick Hall, Derbyshire, about fifteen miles from Chatsworth; Holkar Hall, in Cartmel; Bolton Abbey, Yorkshire; Lismore Castle, Ireland; Compton Place, Eastbourne, Sussex; and Devonshire House, London. The arms of the Duke of Devonshire are—_sable_, three harts’ heads, caboshed, _argent_, attired, _or_. Crest: a serpent noued, _proper_. Supporters: two bucks, _proper_, each wreathed round the neck with a chaplet of roses, alternately _argent_ and _azure_. There are four principal entrances to Chatsworth Park, two of which—those at Edensor and Edensor Mill—are public, and the other two (at Baslow and at Beeley) are private. The Baslow Lodge, shown on our engraving, is stately and noble in the extreme, and forms a fitting entrance to so magnificent a domain. The Beeley Lodge is simple and unassuming; and that at Edensor, with its rustic cottages, remarkably pretty. The most picturesque, however, in regard to its situation, is the Edensor Mill Lodge, which we also engrave. Near it runs the river Derwent, spanned by the single arch of Beeley Bridge, and it is charmingly embosomed in trees and shrubs. [Illustration: _The Grand Entrance-Lodge at Baslow._]
