Again, there are some horses who can run in front of the field for a distance and keep up the pace. They, in fact, run a waiting race in front. These horses, however, are often not _true_ stayers. Desert Gold, Biplane and Gloaming could each do this for a mile and a half; for two miles Prince Bardolph did it in the Sydney Cup with success, and tried to do the same thing in the Australian Cup, but when he had gone two miles and a furlong a horse with a Carbine heart—Defence—caught and beat him easily. Posinatus won his Melbourne Cup in this way from start to finish, and I fancy Newhaven did the same thing, while Harvest King, with a Comedy King staying heart, won the last Australian Cup and led throughout. Now a word on _Endurance_: this is not the same thing as staying. The difference between the two is a matter of pace. For instance, some horses in East India can sprint quite well for three furlongs, but cannot go fast for any distance, yet they are capable of going 80 miles in a cart from sunrise to sunset. This brings home to us that staying power—that is, the ability to go two miles at a very rapid pace—requires a different type of heart to the endurance heart. We may admit that this latter must be a good type of heart, but it is a different type to the staying heart. The endurance heart is well illustrated when we come to deal with jumping horses. We all know of horses that could only get a mile on the flat—say, for instance, Lord Nagar, who won the Villiers—yet when these horses become hurdlers we see them putting up records and winning over two miles in quite brilliant fashion. The explanation is that it is only a matter of _pace_. A cab horse can run two miles, but his pace is nothing. A hurdler can run two miles, but the time he takes would leave him a furlong or two behind in a weight-for-age race. Therefore when we say a horse can _stay_, we imply the possession of a heart that can stand the enormous strain of running two miles, or more, in time that will not much exceed three minutes twenty-six seconds, carrying a good weight. And now that I have mentioned weight, let us ask: What effect has weight on a horse in regard to staying?
