“Guess not! ’Twould be a burnin’ shame to stop them two. An there won’t be any need neyther, they know what they’re doin, Halloran. They ain’t goin’ to ride down nobody. Did ye iver see a finer seat. I’d bet that’s an English cavalry man. Look at the spring of him. Be the Lord I’d like to be in his shoes this minute!”

Amongst the few riders Athlyne passed on his course were an old man and a young woman. The man tall with a big white moustache, a haughty bearing, and steely eyes under shaggy white brows. The girl tall and slim and graceful with black hair and big gray eyes. Both were fairly well mounted, but the girl’s mare was restive and shying at anything. As the black horse came thundering along she had to use considerable skill and force to keep her from bolting. Athlyne had just time for a passing glance as he swept by; but in that instant the face and figure became photographed on his memory. The girl turned and looked after him; she was in the receptive period of her young womanhood when every man has a charm, and when such a noble figure as was now presented is a power. With a sigh she turned and said to her companion:

“That is the horse that we saw sold at the Horse Exchange. I was jealous of whoever bought it then. I’m not now; a man who can ride like that deserves him. Daddy, don’t you think he is something like what a man ought to be? I do!”

“You’re right, little girl! But you’d better not say things like that to any one else but me; they mightn’t understand!” Joy made no answer but she smiled to herself. During the hour or two that followed she chatted happily with her father. They had occasional canters and gallops until the road got too crowded when they went along more sedately. Whenever her father suggested turning homeward she always pleaded for one more turn:

“Just one more, Daddy. It is so delightful here; and the river is so lovely.” Of course she had her way. The old man found more true happiness in pleasing her than in any other way. In her heart, though she did not tell her father for she felt that even he mightn’t understand, she had a wish that the man on the black horse would return the same way. She had a feeling that he would.

After his gallop Athlyne went quietly along the road past Grant’s Tomb and followed the course of the Drive. Here the road descended, circling round the elevation on which the Tomb is erected. Below it is the valley of some old watercourse into the Hudson. This valley has been bridged by a viaduct over which the Drive continues its course up the side of the river for many miles. To-day however, it was necessary to make a detour, descend the steep on the hither side of the valley and rise up the other side. Some settlement had affected the base of the up-river end of the bridge and it had given way. The rock on which New York is based is of a very soft nature, and rots slowly away, so that now and again a whole front of a house will slide down a slope, the underlying rock having perished. Not long before, this had actually happened to a group of houses in Park Row. Now the bridge had fallen away; the road ended abruptly, and below lay a great shapeless mass of twisted metal and stone. The near end of the viaduct was barred off with wooden rails, and in the centre was a great board with a warning that the thoroughfare was closed.

Athlyne rode up as far as the Up-Town Club, sat for awhile amongst the trees on the river bank and thought of many things. Amongst these of the girl with the gray eyes who looked so admiringly at his horse—or himself. Perhaps he accepted the latter alternative, for as his thoughts ran he smiled and stroked his big moustache.

When he rode towards town again he kept a sharp look out, unconsciously slackening speed when any old man and young woman riding together came in sight. He had ascended the eastern side of the valley, over which lay the broken viaduct, and commenced to traverse the curved slope leading up to Grant’s Tomb when he heard a sudden shouting on the road in front and saw a rush of people to both sides and up the steps to the Tomb. An instant after a mounted constable appeared urging his horse to a gallop as he cried out:

“Clear the road! Clear the road! It’s a run-a-way!” Instinctively Athlyne drew to the roadside, a double purpose in his mind; to keep the way clear as directed, and to be able to render assistance if possible. The noise and cries drew closer and there was on the hard road a thunder of many hoof strokes. Then round the curve swept a brown mare dashing madly in a frenzied gallop—the neck stretched out and the eyes flaming. The woman who rode her, a tall girl with black hair and great gray eyes, sat easily, holding her reins so as to be able to use them when the time should come. She was in full possession of herself. She did not look frightened, though her face was very pale. Behind her but a little way off came two mounted policemen and the old man with the big white moustache. Other men variously mounted came hurrying in the background; beyond them a whole long series of horse vehicles and motor cars.

As he saw her Athlyne’s heart leaped. This was the girl whose face had attracted him; his time had come quicker than he had dared to hope. He shook his reins and started his horse, spurring him with his heels as he did so. If he was to be of service he should be able to keep at least equal pace; and that would require a quick start, for the runaway was going at a great pace.
