I suspect the Indian poem existed only by the challenger’s invention.  Before I leave my faint and unworthy record of these great times I am tempted to mention an incident poignant with tragical associations.  The first night after Christmas the holly and the pine wreathed about the chandelier above the supper-table took fire from the gas, just as we came out from the reading, and Longfellow ran forward and caught the burning garlands down and bore them out.  No one could speak for thinking what he must be thinking of when the ineffable calamity of his home befell it.  Curtis once told me that a little while before Mrs. Longfellow’s death he was driving by Craigie House with Holmes, who said be trembled to look at it, for those who lived there had their happiness so perfect that no change, of all the changes which must come to them, could fail to be for the worse.  I did not know Longfellow before that fatal time, and I shall not say that his presence bore record of it except in my fancy.  He may always have had that look of one who had experienced the utmost harm that fate can do, and henceforth could possess himself of what was left of life in peace.  He could never have been a man of the flowing ease that makes all comers at home; some people complained of a certain ‘gene’ in him; and he had a reserve with strangers, which never quite lost itself in the abandon of friendship, as Lowell’s did.  He was the most perfectly modest man I ever saw, ever imagined, but he had a gentle dignity which I do not believe any one, the coarsest, the obtusest, could trespass upon.  In the years when I began to know him, his long hair and the beautiful beard which mixed with it were of one iron-gray, which I saw blanch to a perfect silver, while that pearly tone of his complexion, which Appleton so admired, lost itself in the wanness of age and pain.  When he walked, he had a kind of spring in his gait, as if now and again a buoyant thought lifted him from the ground.  It was fine to meet him coming down a Cambridge street; you felt that the encounter made you a part of literary history, and set you apart with him for the moment from the poor and mean.  When he appeared in Harvard Square, he beatified if not beautified the ugliest and vulgarest looking spot on the planet outside of New York.  You could meet him sometimes at the market, if you were of the same provision-man as he; and Longfellow remained as constant to his tradespeople as to any other friends.  He rather liked to bring his proofs back to the printer’s himself, and we often found ourselves together at the University Press, where the Atlantic Monthly used to be printed.  But outside of his own house Longfellow seemed to want a fit atmosphere, and I love best to think of him in his study, where he wrought at his lovely art with a serenity expressed in his smooth, regular, and scrupulously perfect handwriting.  It was quite vertical, and rounded, with a slope neither to the right nor left, and at the time I knew him first, he was fond of using
