Notwithstanding the magnitude of his bets, Lord George was always cool in temperament while other men who, though they might be quite able to stand a loss, were full of nervous excitement when only a small sum was risked.
He kept on terms of affection with his mother and sisters and he could always rely upon the Duchess for help when his racing extravagances had led him too far.
Lord George was over six feet in stature and his figure was handsome and distinguished. His style of dress was according to the best canons of fashion, elegant and fastidious. A long gold chain was looped upon the breast of his waistcoat and with it he wore costly jewels. He had a new satin scarf of cream colour every day, although the cost of each was about a sovereign.
A frock coat and tall beaver hat completed his costume. His race-course attire consisted of a green coat, top boots and buckskin breeches.
When in Nottinghamshire he used to hunt with the Bufford hounds and kept his hunters at Welbeck.
He was a Freemason, though he does not appear to have had time from his devotion to politics and racing to take any high position in the Order. As to some of his personal habits it may be said that he was not a smoker; but he drank four glasses of wine at dinner-time.
The figure of Lord George has been described by his friend Benjamin Disraeli, afterwards Earl of Beaconsfield, in a few striking sentences thus: "Nature had clothed this vehement spirit with a material form which was in perfect harmony with its noble and commanding character. He was tall and remarkable for his presence; his countenance almost a model of manly beauty; the face oval, the complexion clear and mantling; the forehead lofty and white; the nose aquiline and delicately moulded; the upper lip short. But it was in the dark brown eye that flashed with piercing scrutiny that all the character of the man came forth; a brilliant glance, not soft, but ardent, acute, imperious, incapable of deception or of being deceived."
He was a dandy rivalling d'Orsay, his cravats made other young men of his time envious, and his suits were in the highest style of taste. They were indeed works of art worthy of the genius of Beau Brummell. As for the House of Commons, until he turned serious politician, he treated that old-fashioned assembly with haughty indifference, and when he was pressed to record his vote in party division he entered the House on more than one occasion at a late hour, "clad in a white great-coat, which softened, but did not conceal, the scarlet hunting coat beneath it."
He was a breeder and backer of horses for twenty years, and the recklessness of his wagers staggered the gamblers of his time.
The training of race-horses was brought to a fine art in his day. It had been the custom for owners to send their horses to and fro between Newmarket, Epsom and Doncaster along the high-ways, with the result that although the road hardened their muscles, it militated against their speed.
