The so-called musical ability of horses appears, from all that is known, to be confined within very narrow bounds. Only one fact is universally accepted, viz., horses of the military are believed to possess a knowledge of the significance of trumpet signals, and are often said to interpret them more readily than the recruits.[81] Since no experiments had been made along these lines, I undertook to make a brief test of the cavalry horses mentioned on page 188. As in the preceding tests, the three animals were arranged behind one another with the customary distance of two horses' lengths between, and each was ridden by his accustomed rider. They were held by the reins, but received no aid of any kind, either to start them or to restrain them. A bugle then sounded the various signals at the other end of the barrack's courtyard. We had been previously assured that the horses would certainly react without fail. But, as a matter of fact, the result was quite the contrary. Two of the horses did not move at all, and the third, a thirteen-year old gelding, was startled nearly every time and would tear off in a gallop--even though a trot had been sounded. I would not, however, venture to draw any conclusions from results such as these. Many more tests would have to be made, and some of them upon the whole squadron, before a judgment could be given.[AG] [Footnote AG: Professor Fluegel,[82] basing his statements on an article appearing in "Schorer's Familienblatt" (Berlin, 1890, No. 8, p. 128), gives an account of similar experiments which were supposed to have been conducted by the Zoological Society for Westphalia and Lippe, and presumably showed that "the horses of the military do not understand the bugle calls." No matter how well trained a horse may have been, it would not respond to a signal. This report, however, is due to a mistake. Such experiments have never been made by the society mentioned, so I am told by its director, Dr. Reeker. Nor do I know of any one else who has made experiments of this kind. However, Professor Landois,[83] the eminent zoologist, now deceased (founder of the scientific society mentioned), tested four circus-horses for their musical ability and specifically for their sense of musical time. He arrives at the conclusion that horses "have no feeling for time, whatsoever." With but few exceptions,[84, 85] all experts to-day are of the same opinion. Horse-trainers, especially, are universally agreed on this point. It is easy to see in any circus performance that it is not the horses that accommodate themselves to the music, but that the music accommodates itself to them, and that the trained horses[86] are induced to do their artistic stepping only by the aids given by their riders. Furthermore, all these horses are trained without the use of music.----It would therefore appear that the time had arrived
