In 1856 New Orleans was in the midst of the darkest ten years of her history. Yet she was full of new-comers from all parts of the commercial world,--strangers seeking livelihood. The ravages of cholera and yellow-fever, far from keeping them away, seemed actually to draw them. In the three years 1853, '54, and '55, the cemeteries had received over thirty-five thousand dead; yet here, in 1856, besides shiploads of European immigrants, came hundreds of unacclimated youths, from all parts of the United States, to fill the wide gaps which they imagined had been made in the ranks of the great exporting city's clerking force. Upon these pilgrims Dr. Sevier cast an eye full of interest, and often of compassion hidden under outward impatience. "Who wants to see," he would demand, "men--_and women_--increasing the risks of this uncertain life?" But he was also full of respect for them. There was a certain nobility rightly attributable to emigration itself in the abstract. It was the cutting loose from friends and aid,--those sweet-named temptations,--and the going forth into self-appointed exile and into dangers known and unknown, trusting to the help of one's own right hand to exchange honest toil for honest bread and raiment. His eyes kindled to see the goodly, broad, red-cheeked fellows. Sometimes, though, he saw women, and sometimes tender women, by their side; and that sight touched the pathetic chord of his heart with a rude twangle that vexed him. It was on a certain bright, cool morning early in October that, as he drove down Carondelet street toward his office, and one of those little white omnibuses of the old Apollo-street line, crowding in before his carriage, had compelled his driver to draw close in by the curb-stone and slacken speed to a walk, his attention chanced to fall upon a young man of attractive appearance, glancing stranger-wise and eagerly at signs and entrances while he moved down the street. Twice, in the moment of the Doctor's enforced delay, he noticed the young stranger make inquiry of the street's more accustomed frequenters, and that in each case he was directed farther on. But, the way opened, the Doctor's horse switched his tail and was off, the stranger was left behind, and the next moment the Doctor stepped across the sidewalk and went up the stairs of Number 3-1/2 to his office. Something told him--we are apt to fall into thought on a stair-way--that the stranger was looking for a physician. He had barely disposed of the three or four waiting messengers that arose from their chairs against the corridor wall, and was still reading the anxious lines left in various handwritings on his slate, when the young man entered. He was of fair height, slenderly built, with soft auburn hair, a little untrimmed, neat dress, and a diffident, yet expectant and courageous, face. "Dr. Sevier?" "Yes, sir." "Doctor, my wife is very ill; can I get you to come at once and see her?" "Who is her physician?"
