Rumor says that the young Earl of Clarehaven, who has recently had very heavy losses on the turf, positively intends to capture the Derby this year. It was only a few months ago that we had to condole with the gallant young nobleman on the sad necessity which forced him to sell that great horse Moonbeam last year to the well-known South African capitalist, Mr. Lionel Houston, who indorsed the public view that Moonbeam's defeat in the Derby by his own horse Chimpanzee was not true form when he sold Chimpanzee to an Australian syndicate of breeders and bought Moonbeam for the stud he is now forming, and which we have no doubt will give many famous new names to the history of English racing. But our readers' present concern is what is popularly known as the Starkey Lodge Puzzle. We have the highest authority for saying that this is no longer a puzzle. At an important trial held in great secrecy on the Starkey Lodge training-grounds it was conclusively established that Vanity Girl is more than likely to give the Blue Riband of the turf to Lord Clarehaven and console him for the failure of Moonbeam. It will interest our readers from the smallest punter upward to hear that Full Moon, the victor of the Two Thousand Guineas and the present Derby favorite, will not run at Epsom, having been sold like his half-brother to Mr. Lionel Houston, who no doubt intends to keep him for the St. Leger, a race which he is ambitious of winning. We need scarcely point out to our readers the obvious tip for this year's Derby, and we do not hesitate to plump right out for Vanity Girl as the winner. We were the only paper to advise our readers not to back Full Moon until the intentions of the stable were a little plainer, and to all those who failed to follow our advice we can only say, "I told you so." Lord Clarehaven has done well to scratch the winner of the Guineas, for there is no doubt that if both the colt and his stable companion had faced the starter at Epsom the public would have followed the son of Cyllene. As it is, we confidently expect to see Vanity Girl a raging favorite before the week is out, and we may remind our readers that Lord Clarehaven's beautiful chestnut has already shown that she likes the Epsom course by winning the Woodcote Stakes last year. Her running at Newmarket last autumn may be discounted. We happened to know that the stable was coughing; as we have hinted, the gallant young nobleman who sports the black, white, and purple was very hard hit by her defeats, and this expression of renewed confidence in the chestnut daughter of Spearmint cannot be disregarded.
