The duties of the editor of the “London Strangers’ Leaf” would not be very onerous. The names and intended addresses of every individual coming from abroad it will not be difficult to obtain. To reach us Islanders every visitor must arrive by sea, and at each port we are blessed with a customhouse. The captain of every steamer is bound for customhouse purposes to have the name of each of his passengers set down in a sort of Way-bill; and, for a slight consideration, the person who performs that office (generally the steward), would doubtless learn and add the address to which each of the passengers is going in London. An arrangement with a customhouse clerk at each of the ports could be made for forwarding daily a copy of the list. Thus a complete record of arrivals from abroad could be obtained with little trouble. The names and lodgings of persons from the provinces would be more difficult of access; but a good understanding with hotel-keepers, and some assistance from the “Lodging-house Committee” (for of course there will be one,) of the Executive of the Great Congress, would insure the editor a tolerably complete “List of the Company” who assemble, even from the country. The “Strangers’ Leaf” might be published early each afternoon so as to give the arrivals of the morning. It is not to be doubted that at the essentially Industrial Meeting of 1851, the _Chevaliers d’Industrie_ of all nations will make it their especial business to attend in large numbers. _Their_ names, personal appearance, addresses, and achievements, it would be very useful to record in “the Strangers’ Leaf.” To our excellent friends the Detectives the benefit would be great and reciprocal: for they would not only derive, but contribute much useful information. As a kind of “Hue and Cry,” of a more refined and fashionable kind, the proposed sheet would be invaluable. Should any enterprising gentleman, literary or otherwise, make the experiment, it may possibly turn out not only useful but profitable. Should such a speculation be deemed too undignified, we would silence the objection with a remark from Macaulay’s Essay on the life of Bacon, to the effect that Nothing is too insignificant for the attention of the wisest, which may be of advantage to the smallest in the community.
