One of Hubback's daughters had in 1795, by Favourite, a roan calf which grew to be the celebrated Durham Ox, which at five and a half years weighed 3,024 lb., and was sold for L140. It was sold again for L250, the second purchaser refusing L2,000 for it, and taking it round England on show made a profitable business out of it, in one day in London making L97. A still more famous animal was the bull Comet, born 1804, which at the great sale in 1810 fetched 1,000 guineas. This bull was the crowning triumph of Colling's career and the result of very close breeding, being described as the best bull ever seen, with a fine masculine head, broad and deep chest, shoulders well laid back, loins good, hind-quarters long, straight and well packed, thighs thick, with nice straight hocks and hind legs. Perhaps Colling thought he had pursued in-and-in breeding too far, at all events in 1810 he dispersed his famous herd. The sale was held at a most propitious time, for the Durham Ox had advertised the name of Colling far and wide, and owing to the war prices were very high. Comet fetched 1,000 guineas, and the other forty-seven lots averaged L151 8s. 5d., an unheard-of sale, yet all the auctioneer got was 5 guineas, much of the work of the sale falling on the owner, and the former sold the stock with a sand-glass. After the sale at Ketton, Brampton, the farm of Charles's brother Robert, became the centre of interest to the Shorthorn world. Robert obtained excellent prices for his stock, five daughters of his famous bull George fetching 200 guineas each. Probably he, like his brother, pursued in-and-in breeding too far, and in 1818 there was another great sale; but war-prices had gone and agriculture was depressed, so that the cattle fetched less than at Ketton, but still averaged L128 14s. 9d. for 61 lots, and 22 rams averaged L39 6s. 4d. Robert died in 1820, his brother in 1836. It cannot be said that the Collings were the founders of a new breed of cattle; they were the collectors and preservers of an ancient breed that might otherwise have disappeared.[513] The object of good breeders was now to get their cattle fat at an early age, and they so far succeeded as to sell three-year-old steers for L20 apiece, generally fed thus: in the first winter, hay and turnips; the following summer, coarse pasture; the second winter, straw in the foldyard and a few turnips; next summer, tolerable good pasture; and the third winter, as many turnips as they could eat.[514] Cattle at this time were classified thus: Shorthorns, Devons, Sussex, Herefords (the two latter said by Culley to be varieties of the Devon), Longhorned, Galloway or Polled, Suffolk Duns, Kyloes, and Alderneys. Sheep thus: the Dishley Breed (New Leicesters), Lincolns, Teeswaters, Devonshire Notts, Exmoor, Dorsetshire, Herefordshire, Southdown, Norfolk, Heath, Herdwick, Cheviot, Dunfaced, Shetland, Irish.[515]
