"I have two reasons," he answered, "for not leading; as there would in that case be no opportunity of studying others, and also, that it seems to me hardly fair. There is no danger to me in facing any possible obstacle, however tricky or difficult, and I might lead others to follow who, through no fault of their own, would very probably come to grief." We had by this time overtaken two other riders, and our private conversation was at an end. I shall never forget that day. We had a most brilliant run, and I kept close to Sydney on purpose to watch his horse. Now that I had a key to the mystery, it was easy to notice the human instinct that guided its every movement. The country was difficult, or I should have found the occupation even more absorbing; as it was, much of my time was taken up in looking after my own animal, which unfortunately by no means always took its jumps in the way I desired. We had been galloping at a great pace for twenty-five minutes, and many of the riders were now far behind, when I noticed that we were approaching some fairly stiff rails, on the further side of which there was a broad, deep ditch full of water. If there is one obstacle to which I object more than another, it is a combination of this description. Three or four of the horses cleared it in safety, but a girl, riding just in front of Sydney, was unable to get her horse in hand. Consequently, instead of clearing the top rail the animal came with its full weight into the obstruction, broke the top bar, and getting its legs entangled in the lower timber, turned completely over into the water. So entirely were the horse’s fore-legs fixed in the lower bars, that the girl seemed in great danger of being drowned. It is not easy to imagine a more awful position. To be pressed down with one’s head beneath the water by a horse’s weight, at the same time knowing that it is impossible to do anything to assist the animal in freeing itself! Sydney had taken in the position, and I saw his horse dash forward at full speed. When it came close to the broken rail, it swung quickly round, and striking the lower bars with a violent kick, sent the pieces flying in different directions. It thus freed the struggling horse, and then without a moment’s pause plunged into the water. Sydney was now able to seize the lady’s bridle, and for a moment everything seemed in confusion; then the rescuer’s horse made a gallant plunge, reared up in the water and fell backward between the broken rails. The daring attempt was successful; the weight of the falling horse had given just the impetus Sydney required to lift the other animal and to free its rider, and amid the cheers of those who had now gathered round, the lady was borne in safety to the bank, terribly frightened, though uninjured.
