Among the eccentricities laid to the charge of the old Duke it was said that on his young heir going to visit him on one occasion at Welbeck, he ordered him to stand in a corner of the room.

When in 1879 the old Duke passed away from his world of mysteries and escapades, the heir was a Lieutenant in the Coldstream Guards. He was not long in the Army, and when he came into the title there were too many other engagements for him to attend to without troubling himself as to the routine of military duty, though he kept up a connection with the forces by becoming Lieutenant-Colonel of the Honourable Artillery Company of London, Honorary Colonel of the 1st Lanarkshire Volunteer Artillery, and of the 4th Battalion Sherwood Foresters Regiment.

Welbeck soon began to assume a new aspect under his regime. Gradually it lost its appearance of a contractor's yard and looked like one of the stately homes of England.

Looking back to the time when he first came into his noble heritage, the Duke made a touching reference at the Welbeck Tenants' Show, in 1906, to the death of his agent, Mr. F.J. Turner, who for 48 years was in the service of the fifth Duke and himself.

"When I first came to Welbeck, now twenty-seven years ago," said the Duke, "I was a mere boy, very ignorant of the ways of the world, and more ignorant still, if it were possible, of business habits and of the management of a great estate. I shudder to think what might have been my fate, and the sad fate of those dependent upon me, if Mr. Turner and others, who guided my footsteps, had been different from what they proved themselves to be. It was in his power to make or mar the happiness and prosperity, not only of myself, but also of many of those who live in this district and who farm my land."

The Duke followed the traditions of his family and commenced to form an expensive racing stud.

In 1882 his attention was concentrated to a considerable degree upon this object. He bought the famous sire, St. Simon, at the sale of the late Prince Batthyany's horses. St. Simon could not compete in the classic races in consequence of the death of his owner, and all through his racing career he was not put to any severe test of speed, or most likely his name would have represented the double achievement of being a famous racer, and the sire of famous racers too. He was bought for 1,600l., the purchase being effected on the recommendation of Mat Dawson, the trainer, and the horse was then a two-year-old. That he could go at a terrific pace is proved by an observation made one day by Fred Archer to the trainer. St. Simon was at exercise when Archer's spur touched him, unintentionally by the jockey. He bounded into a gallop—a state of action rarely seen before—and Archer subsequently said that he had never been whizzed through the air at such a terrific pace. In the very pink of condition, fresh and strong, the Duke had to congratulate himself on securing his bargain, for he was sent from the course to the stud, with the result that the magnificent total of 246,000l. was won by his progeny in stakes alone.

At length, in 1888, the Duke reached the goal of his ambition in his career on the turf, for he was the winner of the Derby with Ayrshire, which also won the Two Thousand Guineas. Then he followed up his success next year by winning the Derby again with Donovan, a horse that also won the St. Leger.

The names of the mares finding their habitation at Woodhouse Hall, about a mile and a quarter from Welbeck Abbey, are identified with some of the most remarkable successes of the turf. Here is a string of animals through the veins of which ran purest blood. Amoena, Atalanta, Battlewings, Danceaway, Golden Eye, Lady Mar, Larissa, Marquesa, Mowerina, Modwena, Miss Middlewick, Shaker, Semolina, Staffa, Wheel of Fortune, Tact, Ulster Queen, and many besides. The Goddess of Fortune beamed on his Grace's colours whenever they appeared in the great races. The long series of victories resulted in immense winnings. For instance, Modwena was credited with 5,884l.; Ayrshire, 35,915l.; Johnny Morgan, 4,067l.; Donovan, 55,154l.; Semolina, 12,686l.; Miss Butterwick, 8,179l.; Raeburn, 8,374l.; The Prize, 3,134l.; St. Serf, 5,809l.; Memoir, 17,300l.; Schoolbrook, 2,705l.; Amiable, 10,582l.; Other celebrated stock also bred by the Duke included Anna, Charm, Catcher Clatterfeet, Elsie, Eisteddfod, Galston, Katherine II., Little Go, Oyster, Rattleheels, St. Bridget, Simony II., The Task, The Owl, The Smew, Troon, Ulva, and many more. Major Loder's Spearmint was the winner of the Derby in 1906, and it was a bay colt by Carbine—Maid of the Mint, so that a horse owned by the Duke was again associated with the blue ribbon, Carbine having been imported from Australia by his Grace some years before. Carbine had another name, "Old Jack," given him because of his laziness, and a whip-stock, had to be used occasionally to keep him up to the mark. An Australian picture of the horse was painted by Mr. W. Scott, and after being in the possession of Mr. Herbert Garratt for some years was sent to his Grace with a request that he would accept it, which he did.

All the time that the Duke was paying so much attention to horse-racing it was being asked in Nottinghamshire whether Welbeck was ever to see another Duchess of Portland. The palace of the magician in the heart of Sherwood Forest had not had a mistress for forty years, and the gossips were not diffident in expressing their opinion that it was time the splendour of its hospitality was graced by the presence of a Duchess.
