dates from Tunis lie side by side on our table with Brazil nuts and guava jelly and damson cheese and almonds and raisins. We forget where everything comes from nowadays, in our general consciousness that they all come from the Queen Victoria Street Stores, and any real knowledge of common objects is rendered every day more and more impossible by the bewildering complexity and variety, every day increasing, of the common objects themselves, their substitutes, adulterates, and spurious imitations. Why, you probably never heard of manilla hemp before, until this very minute, and yet you have been familiarly using it all your lifetime, while 400,000 hundredweights of that useful article are annually imported into this country alone. It is an interesting study to take any day a list of market quotations, and ask oneself about every material quoted, what it is and what they do with it. For example, can you honestly pretend that you really understand the use and importance of that valuable object of everyday demand, fustic? I remember an ill-used telegraph clerk in a tropical colony once complaining to me that English cable operators were so disgracefully ignorant about this important staple as invariably to substitute for its name the word “justice” in all telegrams which originally referred to it. Have you any clear and definite notions as to the prime origin and final destination of a thing called jute, in whose sole manufacture the whole great and flourishing town of Dundee lives and moves and has its being? What is turmeric? Whence do we obtain vanilla? How many commercial products are yielded by the orchids? How many totally distinct plants in different countries afford the totally distinct starches lumped together in grocers’ lists under the absurd name of arrowroot? When you ask for sago do you really see that you get it? and how many entirely different objects described as sago are known to commerce? Define the use of partridge canes and cohune oil. What objects are generally manufactured from tucum? Would it surprise you to learn that English door-handles are commonly made out of coquilla nuts? that your wife’s buttons are turned from the indurated fruit of the Tagua palm? and that the knobs of umbrellas grew originally in the remote depths of Guatemalan forests? Are you aware that a plant called manioc supplies the starchy food of about one-half the population of tropical America? These are the sort of inquiries with which a new edition of “Mangnall’s Questions” would have to be filled; and as to answering them—why, even the pupil-teachers in a London Board School (who represent, I suppose, the highest attainable level of human knowledge) would often find themselves completely nonplussed. The fact is, tropical trade has opened out so rapidly and so wonderfully that nobody knows much about the chief articles of tropical growth; we go on using them in an uninquiring spirit of childlike faith, much as the
