Before much had been accomplished under these rules, Wallace, who was as militant as he was ingenious, got into a dispute with the Kentucky breeders over methods of breeding, the value of thoroughbred blood, the genuineness of his published pedigrees and about anything else that came along. So the Kentuckians started the “Breeders’ Trotting Stud Book,” the standard for it being a little modified. In a year or so, Wallace, seeing that the war was going against him, sold out his register and retired from the field. Then new rules were adopted, as follows: “THE TROTTING STANDARD “When an animal meets these requirements and is duly registered, it shall be accepted as a standard-bred trotter:— “1. The progeny of a registered standard trotting horse and a registered standard trotting mare. “2. A stallion sired by a registered standard trotting horse, provided his dam and grandam were sired by registered standard trotting horses, and he himself has a trotting record of 2.30 and is the sire of three trotters with records of 2.30, from different mares. “3. A mare whose sire is a registered standard trotting horse, and whose dam and grandam were sired by registered standard trotting horses, provided she herself has a trotting record of 2.30, or is the dam of one trotter with a record of 2.30. “4. A mare sired by a registered standard trotting horse, provided she is the dam of two trotters with records of 2.30. “5. A mare sired by a registered standard trotting horse, provided her first, second, and third dams are each sired by a registered standard trotting horse. “THE PACING STANDARD “When an animal meets these requirements and is duly registered, it shall be accepted as a standard-bred pacer:— “1. The progeny of a registered standard pacing horse and a registered standard pacing mare. “2. A stallion sired by a registered standard pacing horse, provided his dam and grandam were sired by registered standard pacing horses, and he himself has a pacing record of 2.25, and is the sire of three pacers with records of 2.25, from different mares. “3. A mare whose sire is a registered standard pacing horse, and whose dam and grandam were sired by registered standard pacing horses, provided she herself has a pacing record of 2.25, or is the dam of one pacer with a record of 2.25. “4. A mare sired by a registered standard pacing horse, provided she is the dam of two pacers with records of 2.25. “5. A mare sired by a registered standard pacing horse, provided her first, second, and third dams are each sired by a registered pacing horse. “6. The progeny of a registered standard trotting horse out of a registered standard pacing mare, or of a registered standard trotting mare.”
