A word had better perhaps be said, and said here, as to my share in its composition. It is now twelve years ago since my friend--then Mrs. Brassey--asked my advice and assistance in arranging the Diary she had kept during the eleven months' cruise of the 'Sunbeam'. This assistance I gladly gave, and she and I worked together, chiefly at reducing the mass of information gathered during the voyage. I often felt it hard to have to do away with interesting and amusing matter in order to reduce the book even to the size in which it appeared. It was a very pleasant and easy task, and I think the only difference of opinion which ever arose between us was as to the intrinsic merit of the manuscript. No one could have been more diffident than the writer of those charming pages; and it needed all the encouragement which both I and her friend and publisher, Mr. T. Norton Longman, could offer, to induce her to use many of the simple little details of her life, literally 'on the ocean wave'.
