You may remember Wordsworth's fine lines on "Yarrow Unvisited," "Yarrow Visited," and "Yarrow Revisited." "America Unvisited"--that is now for me a vision of the past; that fabulous America, in which, before they come to your shores, Englishmen believe Pennsylvania to be the capital of Massachusetts, and Chicago to be a few miles from New York--that has now passed away from my mind forever. "America Visited"; this, with its historic scenes and its endless suggestions of thought, has taken the place of that fictitious region. Whether there will ever be an "America Revisited" I cannot say; but if there should be, it will then be to me not the land of the Pilgrim Fathers and Washington, so much as the land of kindly homes, and enduring friendships, and happy recollections, which have now endeared it to me. One feature of this visit I fear I cannot hope to see repeated, yet one without which it could never have been accomplished. My two friends, to whom such a pleasing reference has been made by Dr. Adams, who have made the task easy for me which else would have been impossible; who have lightened every anxiety; who have watched over me with such vigilant care that I have not been allowed to touch more than two dollars in the whole course of my journey--they, perchance, may not share in "America Revisited." But if ever such should be my own good fortune, I shall remember it as the land which I visited with them; where, if at first they were welcomed to your homes for my sake, I have often felt as the days rolled on that I was welcomed for their sake. And you will remember them. When in after years you read at the end of some elaborate essay on the history of music or on Biblical geography the name of George Grove, you will recall with pleasure the incessant questionings, the eager desire for knowledge, the wide and varied capacity for all manner of instruction, which you experienced in your conversations with him here. And when also hereafter there shall reach to your shores the fame of the distinguished physician, Dr. Harper, whether in England or in New Zealand, you will be the more rejoiced because it will bring before you the memory of the youthful and blooming student who inspected your hospitals with such keen appreciation, so impartially sifting the good from the evil.
