At Canche, near Étaples, has been evade out a series of mounds forming a semicircle some eight hundred and fifty feet in extent. These mounds are made up of successive layers of shells and charcoal, the relics of successive occupations. Lastly we must mention a kitchen-midding situated at the mouth of the Somme, which is eight hundred and twenty feet long by about one hundred wide. It consists principally of shells of adult species, with which are mixed fragments of coarse black pottery and numerous goat and sheep bones, the latter bearing witness to a more recent date than that of the kitchen-middings of Scandinavia or of Germany. Throughout Europe similar facts are coming to light. Evans mentions heaps of shells on the coasts of England. Chantre speaks of others near Lake Gotchai in the Caucasus, and Nordenskiöld of others at Cape North, to which he wishes to restore its true name of Jokaipi. He sass these mounds are exactly like those of Denmark. It is, however, chiefly in America that these heaps attract attention, for there huge shell-mounds stretch along the coast in Newfoundland, Nova Scotia, Massachusetts, Louisiana, California, and Nicaragua. We meet with them again near the Orinoco and the Mississippi, in the Aleutian Islands, and in the Guianas, in Brazil and in Patagonia, on the coasts of the Pacific as on those of the Atlantic. Owing to the darker color of the vegetation growing on them, the shell-heaps of Tierra del Fuego are seen from afar by the navigator. For a long time the true character of these mounds was not known, and they were attributed to natural causes, such as the emergence of the ancient coast-line from the sea, and it was not until lately that it was discovered that they were the work of men.
