"It's all old Mason's doing, Fortescue," said he. "He advised me to bring him over. I'm off now. Look at that knot of people coming over the hill; there are some who crossed the Channel yesterday with me who would know my old pet, and I would not have it blown upon for a trifle—the horse has been in Ireland for a week on the quiet. I'm now off, across country to Athenry, where Mason is, and has a stable for him. The horse will leave by the late train to-night for England with a lad; so no one will be a bit the wiser. My old stud-groom will come to your diggings this evening with me to give you a help. So au revoir till mess-time, when you will see yours truly;" and putting his horse at a five-foot wall, he sent him over, hurling the loose stones behind him in a cloud, and was quickly out of sight.

"So your friend has gone," said the gallant Colonel, as Fortescue walked his horse up to a host of his brother-officers and friends assembled in a knot on the hill, amongst which several strangers were distinguishable.

"Yes," replied Fortescue, carelessly, "he will be with us at mess. Here, take the horse home, Forester"—to his man—"see no one comes near him."

"That's a horse to back," said a sly-looking little man in a large drab overcoat; and coming up to Fortescue he whispered quietly to him: "I'm on your nag for a plumper. I keep my own counsel, and shall not split. I never come except with a rush at the last minute. My glasses are good. You've had a spin with one of the best cross-country horses in England. Clever and fast as that nag is, he can't give you seven pounds. You ran him to a length or two. I know George Bradon and Guardsman well. I've won a pot full of money on them before. There, don't look scared; you are a youngster. Sit well down on Screwdriver, hold him together, don't give a lead over the water, and you will land him a winner. I know more than you think; but for my own sake I'm MUM!"

"News for you all!" said the Colonel of Fortescue's regiment, bursting into the mess-room, where some nine or ten officers were at breakfast, amongst whom were Lord Plunger and Bradon. "Here, Fortescue," continued the excited old gentleman, "this letter"—holding out one—"concerns you more immediately. Read it out."

The young man thus addressed took the letter and read the following:—

"Dear Colonel,

"As you all know, this is the morning of the race. Something has happened. For God's sake ride over and see me at once.—

"Yours faithfully,

"P. O'Rooney.
