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.
Some of these kitchen-middings are of great size. Sir Charles Lyell describes one on St. Simon’s Island, at the mouth of the Altamaha (Georgia), which covers ten acres of ground and varies in height from five to ten feet. It consisted almost entirely of oyster shells. In America, as in Europe, excavations brought to light hatchets, flints, arrows, and fragments of pottery. Another of these mounds, near the St. John River, consists, as does that visited by Lyell, of oyster shells, and is of extraordinary dimensions, being three hundred feet long, and though the exact width cannot be made out, is certainly several hundred feet across. Putnam[8] gives an account of the excavation of one of these mounds formed of shells of the Mya, Venus, Pecten, Buccinum, and Natica genera. It stretched along the sea-coast for a distance of several hundred feet, it was from four to five feet thick, and penetrated some distance below the surface of the ground. The valves had been opened with the aid of heat, and the animal bones found with the shells had been broken with heavy hammers which were found in the kitchen-midding. The bones included those of the stag, the wolf, and the fox. Fishes were also represented by remains of the cod, the plaice, and chelonia by turtle shells. Some bird bones were also found, and the knives, arrow- and spear-heads, scrapers, etc., were all of the rudest workmanship. Mr. Phelps has superintended yet more important excavations at Damariscotta[9] and all along the coast to the month of the Penobscot. In the lowest layers he made out ancient hearths, and found numerous fragments of pottery which are the most ancient examples of keramic ware found in New England, and were covered with incised ornamentation of considerable refinement.
The kitchen-middings of Florida and Alabama are even more remarkable. There is one on Amelia Island which is a quarter of a mile long with a medium depth of three feet and a breadth of nearly five. That of Bear’s Point covers sixty acres of ground, that of Anercerty Point one hundred, and that of Santa Rosa five hundred. Others taper to a great height. Turtle Mound, near Smyrna, is formed of a mass of oyster shells attaining a height of nearly thirty feet, and the height of several others is more than forty feet.[10] In all of them bushels of shells have already been found, although a great part of the sites they occupy are still unexplored; huge trees, roots, and tropical creepers having, in the course of many centuries, covered them with an almost impenetrable thicket.
Whether man did or did not live in the basin of the Delaware at the most remote times of which we have any knowledge, we meet with traces of his occupation in the same latitude at more recent periods. At Long-Nick-Branch is a shell-mound that extends for half a mile, and in California there is a yet larger kitchen-midding. It measures a mile in length by half a mile in width, and, as in similar accumulations, excavations have yielded thousands of stone hammers and bone implements ([Fig. 24]).
The shell-mounds of which we have so far been speaking are all near the sea, but there is yet another consisting entirely of marine shells fifty miles beyond Mobile. This fact seems to point to a considerable change in the level of the ground since the time of man’s first occupancy, for he is not likely to have taken all the trouble involved in carrying the mollusca necessary for his daily food so far, when he might so easily have settled down near the shore.
I cannot close this account of the kitchen-middings, without calling attention to two very interesting facts. The importance of these mounds bears witness alike to the number of the inhabitants who dwelt near them, and the long duration of their sojourn. Worsaae sets back the initial date of the most ancient of the shell-mounds of the New World more than three thousand years. This is however a delicate question, on which in the present state of our knowledge it is difficult to hazard a serious opinion. It is easier to come to a conclusion on other points: the close resemblance, for instance, between the kitchen-middings of America and those of Europe. In both continents we find the early inhabitants fed almost entirely on fish; their weapons, tools, and pottery were almost identical in character; and in both cases the characteristic animals of Quaternary times had disappeared, and the use of metals still remained unknown. Are these remarkable coincidences the result of chance, or must we not rather suppose that people of the same origin occupied at the same epoch both sides of the Atlantic?
The man of the kitchen-middings evidently had a fixed abode. Long since, the tent, the temporary shelter of the nomad, had given place to the but. We have already said what this but may have been like, but the most certain data we have as to human habitations at this still but little known epoch, are those supplied by the Lake Stations of Switzerland, and it is to our own generation that we are indebted for the first discoveries relating to them.
The memory of these Lake Stations bad completely passed away, and it was only the long drought which desolated Switzerland in 1853 and 1854, and the extraordinary sinking of Lake Zurich, revealing the piles still standing, that attracted the attention of archæologists. In the space still enclosed by these piles lay scattered pell-mell stones, bones, burnt cinders of ancient hearths, pestles, hammers, pottery, hatchets of various shapes, implements of many kinds, with innumerable objects of daily use. These relics prove that some of the ancient inhabitants of Switzerland had dwelt on the lake where they were found, in a refuge to which they had probably retired to escape from the attacks of their fellow-men or wild beasts. Though they bad succeeded in getting away from these enemies, they were to fall victims to a yet more formidable adversary, and the half-burnt piles have preserved to our own day the traces of a conflagration that destroyed the Lake dwelling so laboriously constructed.
