But their price is reckoned according to the marketable valne of such articles, bu{:" .-'- according to the trnnble which may have been bestowed in col- lecting and assorting them; and thus they are often dearer on the spot than in London. Some time ago a diving-bell was sent ont by an English company for pearl fishing? but it did not answer their expectatio% and several causes may be assigned for its failure.
