Boy reader, I am told that you are not tired of my company. Is this true? "Quite true, dear Captain, -quite true " That is your reply. You speak sincerely? I believe you do. In return, believe me, when I tell you I am not tired of yours; and the best proof I can give is, that I have come once more to seek you. I have come to solicit the pleasure of your company, -not to an evening party, nor to a ball, nor to the Grand Opera, nor to the Crystal Palace, nor yet to the Zoological Gardens of Regent's Park, -no, but to the great zoological garden of Nature. I have come to ask you to accompany me on another "campaign,"-another "grand journey" through the fields of Science and Adventure. Will you go? "Most willingly-with you, dear Captain, anywhere." Come with me, then.
