No race-horse, or at most extremely few, is sent upon the course without having been previously subjected to the ordeal of a trial at home, but it is very questionable whether these tests are of anything like the value which they are supposed to be. In fact, it is something like asking too much of a horse to expect him to run up to the same form upon two or three different occasions, as there is no knowing how the animal may be feeling at the time he is being put through the mill. Chifney, in his "Genius Genuine", asserts that an animal named Magpie would run the same distance nearly two hundred yards better on some days than on others, and few people who have written upon the subject of the race-horse have been in a better position to express an opinion upon such a subject than he. At the same time there can be no gainsaying the fact that, assuming the trial horse is in form and willing, trials must be regarded as being very valuable guides to trainers in estimating the merits of their charges, though, it may be repeated, there is a tendency on the part of many supporters of the Turf to attach a great deal too much importance to the results of home efforts.
