Beche-de-mer realises as much as 160 pounds per ton. In former days "red prickly fish," was the most highly-prized on the Chinese markets, but several years ago a fisherman in the neighbourhood of Cooktown used a copper boiler. Several Chinese epicures died after partaking of soup made from a particular parcel, and "red prickly" was forthwith credited with poisonous qualities. The consignment was traced to its origin, and popular opinion at the time was that the boiler had, unknown to the proprietor of the station, induced verdigris. Investigation, however, gave ground for the belief that the fish in the boiling exuded juices of such corrosive qualities that the copper was chemically acted upon. Beche-de-mer, is now invariably cooked in iron vessels, the bottom half of a malt tank being a common boiler, and the "red prickly," after being absolutely worthless for many years--so quaint are Oriental prejudices--is now regaining favour in that market. Beche-de-mer, though called fish by tradesmen, neither swims nor floats; neither does it crawl, nor wriggle, nor hop, skip nor jump. It simply "moves" on the ocean floor, when not reposing in apparently absolute and unconscious idleness like its distant relative, the star-fish. Nor does the creature possess any means of self-protection. Some species are rough and prickly, and are said to irritate the hand that grasps them. Others either in nervousness, or a result of shock to the system, or to amaze and affright the beholder, shoot out interminable lengths of filmy, cottony threads, white and glutinous, until one is astonished that a small body should contain such a quantity of yarn ready spun, to eject at a moment's notice like the mazes of ribbon drawn from a conjurer's hat.
