Little or no delay took place under the able directorship of Col. W. H. Johnson. When they were marshaled into line, he tapped the drum to one of the most capital starts I have ever seen, the fifteen going away like a platoon of cavalry, except the Baywood colt, who hung at the post. Volcano jumped away first, with McCreery second, and Searcher third, the remainder bunched, coming round the turn to the quarter pole 25-1/2 seconds. They came at a rapid rate down the stretch and past the stand in 50 seconds, McCreery first, Volcano second, Searcher third, Aristides fourth, the others pretty well bunched. Before they had reached the quarter, 1:17, Aristides had gone to the front and opened a gap of two lengths down the back stretch, Volcano second, Searcher third, the mile 1:43-1/4. The pace was so hot that it began to tell and the field was stretched over a good deal of ground. The race from this point home was never in doubt, Aristides winning by two lengths with something in hand, Volcano second, a length in front of Verdigris third, who came rapidly on the home stretch inside the distance. Bob Woolley who was caromed against on the lower turn a good fourth. Ten Broeck fifth, the Baywood colt sixth, Bill Bruce seventh, the remainder were scattered at wide intervals, and the dust was so great that I was unable to place the others. Time--2:37-3/4. DESCRIPTION OF THE WINNER Aristides is a chestnut colt, with a star, and two white pasterns behind. He stands fifteen hands, one and three-quarter inches high. He has a neat head and neck running into rather a straight shoulder, with great length, good barrel, excellent hips and stifles, sound feet and legs well under him. He has fine turn of speed, and from the way he finished up the Derby to-day gives every evidence of being a good stayer. He was bred by Mr. H. P. McGrath, at McGrathiana Stud Farm, near Lexington, Ky., and is by Imp. Leamington, out of Sarong, by Lexington, her dam The Greek Slave, by Imp. Glencoe--Margaret Hunter, by Imp.
