In politics he was a moderate Whig. The leading members of his party recognized his high abilities, and thought it desirable to enlist them in the public service. An opportunity soon presented itself. In the month of February, 1855, Lord John Russell was appointed as British Plenipotentiary to the conference to be held at Vienna for the purpose of settling the terms of peace between Russia and Turkey. Lord John invited Lord Dufferin to accompany him on the mission as a special _attaché_. The invitation was accepted, and Lord Dufferin repaired to the Austrian capital, where he remained until the close of the ineffectual conference. Soon after his return to England he determined upon a long yachting tour in the far northern seas, and in the early summer of 1856 he started on his adventurous voyage. The chronicle of this expedition, written with graphic force and humour by the pen of Lord Dufferin himself, has long been before the world under the title of "Letters from High Latitudes." The voyage, which lasted several months, was made in the schooner-yacht _Foam_, and included Iceland, Jan Meyen and Spitzbergen in its scope. There is no necessity for extended comment upon a book that has been read by pretty nearly everybody in Canada. Who is there among us who has not laughed over the account of that marvellous bird that, as the nights became shorter and shorter, never slept for more than five minutes at a stretch, without waking up in a state of nervous agitation lest it might be cock-crow; that was troubled by low spirits, owing to the mysterious manner in which a fresh member of his harem used to disappear daily; and that finally, overburdened by contemplation, went melancholy mad and committed suicide? Or over that extraordinary dog-Latin after-dinner speech by Lord Dufferin during his stay in the Icelandic capital, as voraciously recorded in Letter VI.? And who among us has failed to recognize the graphic power of description displayed in the account of the Geysers? Or the weird poetic force of "The Black Death of Bergen"? In all these various kinds of composition the author showed great natural aptitude, and his book, as a whole, is one of the most interesting chronicles of travel in our language.
