At this period of his life, Longfellow's journals and letters show much unrest and even at times a loss of interest in his work. His trip abroad for his health did not restore the satisfaction and contentment that he had once known. The needs of both heart and mind must be supplied in order that he might be at peace. Consequently we are not surprised by his marriage, in July, 1843, to Frances Appleton, the heroine of the romance _Hyperion_, and a most admirable and attractive young woman, fitted in every way to be the companion of the poet. The couple went to live in the Craigie House [Footnote: This house is celebrated not only as the poet's home but as having been at one time the headquarters of Washington.] at Cambridge, and entered upon a life of almost ideal domestic harmony. Year after year passed, with little to mar the calm of the Longfellow home. The professor's days were filled with lectures to the college classes, with composition of original verse or translation from foreign literature and with letter writing, answers to unnumbered requests for autographs and calls from distinguished persons or from obscure but aspiring writers. Only a man of rare patience and kindness would have given such a great portion of his time as Longfellow gave during these and all the subsequent years of his life to answering the many inexcusable and often ridiculous requests for explanation of the motives and meaning of his writings, for help in obtaining public recognition, for criticism of poems that the writers submitted and for a variety of other favors. Often there were visits to the opera or attendance at concerts, always in company with Mrs. Longfellow. Sometimes the day was darkened by the illness of one of the children. Then again, with the little ones of the household, the Harvard professor, casting aside his dignity, with all serious cares, would enter with all, his heart into some childish game. Such a good time did he have that he found it worth while to make in his journal such entries as: "Worked hard with the children, making snow-houses in the front yard, to their infinite delight;" "After dinner had all the children romping in the haymow;" "Coasted with my boys (Charles and Ernest) for two hours on the bright hill-side behind the Catholic Church;" "After tea, read to the boys the Indian story of _The Red Swan._" Frequently he accompanied on pleasure excursions his three daughters, the young girls described for us in the familiar lines: "Grave Alice and laughing Allegra And Edith with golden hair." From time to time the journal records an idea for a poem or the beginning of the work of composition, sometimes expressing the doubts and fears that attend this beginning. Thus under date of November 16, 1845, is the statement: "Before church, wrote 'The Arrow and the Song,' which came into my mind as I stood with my back to the fire, and glanced on to the paper with arrowy speed. Literally an improvisation."
