A common New-England rider with his toes turned out, his elbows jerking and the daylight showing under him at every step, bestriding a cantering beast of the plebeian breed, thick at every point where he should be thin, and thin at every point where he should be thick, is not one of those noble objects that bewitch the world. The best horsemen outside of the cities are the unshod countryboys, who ride “bareback,” with only a halter round the horse's neck, digging their brown heels into his ribs, and slanting over backwards, but sticking on like leeches, and taking the hardest trot as if they loved it.--This was a different sight on which the Doctor was looking. The streaming mane and tail of the unshorn, savage-looking, black horse, the dashing grace with which the young fellow in the shadowy sombrero, and armed with the huge spurs, sat in his high-peaked saddle, could belong only to the mustang of the Pampas and his master. This bold rider was a young man whose sudden apparition in the quiet inland town had reminded some of the good people of a bright, curly-haired boy they had known some eight or ten years before as little Dick Venner. This boy had passed several of his early years at the Dudley mansion, the playmate of Elsie, being her cousin, two or three years older than herself, the son of Captain Richard Venner, a South American trader, who, as he changed his residence often, was glad to leave the boy in his brother's charge. The Captain's wife, this boy's mother, was a lady of Buenos Ayres, of Spanish descent, and had died while the child was in his cradle. These two motherless children were as strange a pair as one roof could well cover. Both handsome, wild, impetuous, unmanageable, they played and fought together like two young leopards, beautiful, but dangerous, their lawless instincts showing through all their graceful movements.
