The eale of blood stock to be held by Messrs Pyne and Co. at Middle Park on Wednesday is one of the largest that has been held in Canterbury, and, -with the Middle Park yearlings and two-year olds, and the whole of Mr O'Brien's stud, comprises an unusual number of really first class racing stock. Having on former occa sions expressed my opinion of the merits and demerits of the Middle Park lots, I took advantage of the lovely morning on Mon day last to visit Mr O'Brien and see what manner of yearlings those were he pur chased at Auckland in the summer. There are four of them, three colts and a filly, and being the progeny of sires that are known to few Canterbury men except by name, to wit, Nordenfeldfc, St. Leger, and Captivator, some description of thees youngsters may be interesting. Norden feldt, the bay son of Musket and Onyx, is of course wellknown to usall by name, through his grand performances on the Australian turf, and his career at the stud will be watched with all the more interest as he is a colonial-bred sire. I have heard it eaid that all Musket's get were either browns or bays, with an occasional grey, but nerer on any occasion a chestnut, although he was mated with a number of mares of that coloar, and as Nordenfeldt is by the old horse from the brown mare Onyx it might be expected that his stock would follow on the same lines, but such is not the case, for the first that I saw of Mr O'Brien's, the colt Gatling, by Nordenfeldt from the chestnut mare Petroleuse, takes after his dam in colour. But in. point of size, substance, and quality he fills the eye as satisfactorily as any cf the old horse's stock. He is a very evenly-built colt, standing a trifle o\»er 15 hands, with a good barrel, a rare set of legs, mus cular back, and very deep through the thighs and buttocks, being, although an unfurnished colt, quite solid when you lift his tail, and much wider through at the stifle line than across the hips. The other Nordenfeldt is the brown filly Hazel from Ouida, and consequently rather more than half sister to Artillery, and Hilda who are from the same mare by Musket.
