This victory made him an odds-on favourite for the Derby, and Bobby Lewis, thinking that he had a real Wallace stayer to handle, determined to “make the running” and knock Cetigne out; but he failed for two reasons. In the first place, he hurried his mount most unwisely for the first half-mile, forgetting what Fred Archer had laid down as a rule, that if you hurry a stayer enough for the first half-mile you will kill him dead; and, in the second place, Bobby not being a pathologist did not know anything about dilated hearts, so he evidently took it for granted that his mount’s heart was of the true Wallace brand. But he found to his dismay that he had made so much use of his horse that he died in his hands in the last fifty yards and Cetigne won. The effort certainly did not do Cetigne’s non-staying heart any good, for he never ran a decent race over a distance afterwards, though he lived to win the most dramatic race ever seen at Randwick when he won the Craven Plate in record time in 1918. Now, though Cetigne had a non-staying heart—Grafton being no sire of stayers—yet he must have had a very sound heart to win a Newmarket six furlongs with 9 stone in 1.13½, a Villiers mile in 1.38¼ with 9.4 in the saddle, and lower Woorak’s Craven Plate record of 2.5¼ to 2.4½; and yet he could not run a mile and a half with success in good company. Let me say that a heart that is dilated may recover if the animal is properly rested. Wallace Isinglass being bred to have a staying heart on his sire’s side as well as on his dam’s side, was judiciously nursed by his rich owner, and, as a result, as a four-year-old and a five-year-old he did well over a distance, and lived to defeat Desert Gold at two miles in Melbourne, and to run Lanius and Westcourt to a neck over the Cumberland Stakes two miles. Let us see if we can learn anything of use from the above remarks. The chief lesson that is to be learnt is: _That you can’t make a stayer out of a horse that has not inherited a staying heart, train him as you will_. The old ideal that if you wanted a horse to run two miles you had to train him over that distance was absurd. You must, of course, get the animal’s muscles in a fit condition, and that can be done by slow, long work, and by running him at a fast pace from time to time over a mile or so; but you can’t make his heart carry him two miles _at the requisite pace_ if he does not inherit the proper kind of heart, _no matter how you train him_! It is quite true that a horse in some cases stays better the older he gets, because his heart improves; still the fact remains that the true stayer is _born_, not made.
