Accompanying Benton's eldest daughter to a concert at Miss English's school, Frémont for the first time met Jessie Benton. She produced on his mind at once "the effect that a rose of rare color or a beautiful picture would have done." She was but sixteen years old at the time, in the first bloom of girlish beauty, and her bright mind exhilarated by the pleasure of seeing her sister, poured itself forth in language as sparkling as it was natural. "Her beauty," he wrote later, in describing that first impression of her, "had come far enough down from English ancestry to be now in her that American kind which is made up largely of mind expressed in the face, but it still showed its Saxon descent. At that time of awakening mind, the qualities that made hers could only be seen in flitting shadows across the face or in the expression of incipient thought or unused and untried feeling."

Coming home for the Easter holidays, she found that the young lieutenant had become identified with her father's "Oregon work." He was an almost daily visitor at her home, and in his constant meetings with her in its unreserved atmosphere he found confirmation of the first impression he had formed of her. "There are features," he wrote later, "that convey to us a soul so white that they impress with instant pleasure, and of this kind were hers. Her qualities were all womanly, and education had curiously preserved the down of a modesty which was innate. There had been no experience of life to brush away the bloom."

Before the holidays were over this impression of her had penetrated Frémont's entire being, and he loved her no less profoundly than he admired her, rendering her an absolute devotion that knew no subsequent diminution. "Insensibly and imperceptibly," he said, "there came a glow into my heart which changed the current and color of daily life, and gave a beauty to common things."

That April day in 1841, when, a month after it had witnessed his inauguration, a mourning nation assembled to pay its last tribute to William Henry Harrison, a gray and gloomy day without, Frémont has recorded as the "red letter day" of his life. The government had leased quarters near the Capitol for the use of Nicollet, where the work on the map of the Mississippi's sources was going forward. From the windows of one of the rooms Senator Benton and his family were invited to view the funeral procession as it wound down Capitol Hill. Frémont, on leave of absence for the day, was the host of the occasion. Notwithstanding his best uniform, in which he looked very handsome, he personally tended the cheery log-fire, that gave a touch of cosiness to the big office, which he had, moreover, with somewhat reckless extravagance for a man on a lieutenant's salary, decorated with plants and cut flowers. From a daintily set table he served, with captivating grace, coffee and ices. Though the nation mourned, two hearts, at least, of all who looked upon the solemn pageant of that day were in gala attire.

The next day, though he discreetly sent Mrs. Benton the plants and flowers that had done decorative duty in his office, it availed him nothing in her wise eyes. Jessie was too young, and, besides, she did not wish her to marry an army man; the life was too unsettled. Mrs. Poinsett, the wife of the Secretary of War, was taken into her confidence, and, as a result, Frémont was ordered off to survey the Des Moines River. Jessie, moreover, as a further diversion, was taken to the wedding of one of her Virginia cousins, which meant in those days weeks of festivity.

It was but another case, however, of the best laid plans that "gang aglee," for in the autumn both Frémont and Jessie Benton were back in Washington, and on the 19th of October she was courageous enough, in defiance of both father and mother, whom she not only loved but truly revered, to become Frémont's wife. She married too young, she says herself, ever to have been a belle in the usual acceptation of that term, yet so gifted has she been with those qualities that evoke the chivalry of man that but few American women have had a better right to that title. Though her life has been one of much exposure, she herself has at all times been singularly sheltered.

The year following his marriage, Frémont applied to the Secretary of War for permission to explore the far West and penetrate the Rockies. The plan was supported by Benton, who believed that by making surveys the government would be giving at least a semblance of protection to its Western possessions. Congress gave its sanction, and in May, 1842, with a handful of venturesome spirits gathered on the Missouri frontier, Frémont went forth to the exploration of the southern pass. It was the first of numerous similar expeditions, his scientific reports of which—going into astronomy, botany, mineralogy, geology, and geography—were translated into many tongues, and gave their author world-wide fame.

During his absences, which were always of uncertain duration, his wife sometimes remained in her parents' home. Her father sent for her one morning, when she had been married about a year, and, pointing out her old place at his library table, he said, "I want you to resume your place there; you are too young to fritter away your life without some useful pursuit." So she dropped back quite naturally into her old habits of study, as if her honeymoon days had been but another form of vacation.

She frequently accompanied Frémont, however, as far as St. Louis, waiting there for his return, or going out again to meet him after a fixed time. He was once eight months overdue, during which period of awful silence and suspense she had a supper-table set for him every night with all the comforts and luxuries of that civilization to which he had been so long a stranger. He came at length, in the dead of the night, and, rather than disturb a household, he went to a hotel, and for the first time in eighteen months slept in a bed.

With whatever misgivings she may have seen him set out for a field where he would encounter certainly many dangers, and possibly even death, she never, even when the opportunity came, of which many a weaker woman would have availed herself, endeavored to withhold him from his purpose. He would sometimes, after having covered many miles of his route, come back to her for another good-by, overtaking his party again by hard riding or pressing forward while they were resting.
