WURTHEN (DITHMARSCHEN).
In 1883, Dr. Hartmann, of Marne (B. 397), gave a more detailed account of similar dwellings in the Holstein fen district, near the embouchure of the river Elbe. These, in the form of low mounds, are met with, according to him, in all the marshes along this part of the North Sea coast. In the Dithmarschen, both north and south, they are very numerous, and the larger ones, like the terp-mounds of Holland, are now generally occupied by one or more modern buildings. In extent they vary from 1¼ to 15 acres, and in height from 13 to 23 feet above ordinary mean tides. On several occasions in recent times, in the course of excavating the foundations of new buildings, the digging of wells, etc., various relics, such as fragments of pottery, clay weights, iron implements, bits of manipulated staghorns, broken bones, etc., were turned out, which, however, suggested nothing more than passing comments. But their real nature is now clearly pourtrayed by the facts recorded by Dr. Hartmann, the chief of which were ascertained from excavations conducted by himself in the Fahrstedter Wurth situated some three miles to the north of the Elbe. This Wurth, some years ago, became the property of a brick manufacturer, of the name of Huesmann, who was in the habit, from time to time, of utilising its contents, partly for filling up old clay-pits and partly for manuring purposes. Such was the condition of the Fahrstedter Wurth when Dr. Hartmann's attention was directed to it in August, 1881. On his first visit, while poking about the open trenches, he picked up, at a depth of four feet from the surface, a perforated clay weight, four inches in diameter, and two and a half inches thick. After this he continued his visits to the locality regularly, and, in a short time, collected a number of relics, besides determining many interesting points in regard to the structure of the mound. The greatest depth reached by the haphazard excavations of Mr. Huesmann was nine and a half feet. Along the exposed section down to this point Dr. Hartmann distinguished the following layers:
| 1. | Ordinary soil (Ackererde) | about 2 feet. |
| 2. | Greenish sandy earth (hellgrüne sandige Erde), supposed to be due to sea | |
| action, from the fact of its containing many | ||
| of the spicules or needles of sponges | 1 " | |
| 3. | A layer of reddish clay (rother Estrich) | ½ to 1 " |
| 4. | Remains of wooden structures (Packwerk) | 2 to 4 " |
| 5. | Earth mixed with clay (helle Kleierde) | 1½ " |
This Packwerk is described as made up of decomposed branches, from the size of a finger to, occasionally, the thickness of an arm, arranged horizontally, but sometimes perpendicularly. Its lower portion was composed of large quantities of the twigs of birch and oak, the fibres of several marsh plants, broken bones, and other organic débris. In the underlying clay he noticed some holes, which he concluded to have been due to small piles, the wood of which had disappeared by decomposition. Scattered through this Packwerk were found, besides charcoal and ashes, a varied assortment of the relics of human industry, of which the following may be noted:—Fragments of pottery, (grey and black), among which were some with perforations round the rims; sharpening-stones; a perforated clay weight; twelve portions of quern stones, made of basalt, and having a thickness of one and a half to two and a half inches—from a fragment, the entire diameter of one was ascertained to be 17 inches; several iron knives, a socketed lance-head, and some nails, together with lumps of both iron and glass slag. A wooden handle, some worked objects of bone with marks of rivets, bits of birch-bark, etc. A black mass of asphalt, supposed to be a product of birch-bark, had embedded in it the shell of a hazel-nut. From this it was inferred that the mass was originally in a fluid condition.
Among the osseous remains the following animals were identified by Dr. Pfeffer, of the Natural History Museum at Hamburg, and Dr. Rautenburg:—dog, ox, pig, sheep, stag, horse, bittern (?), and sturgeon (recognised by its scales).
In the clay below the Packwerk (Kleierde) were found the stumps of eight piles, five to six feet apart, which Dr. Hartmann concluded had originally passed upwards through the fascine work, but now only the portions embedded in the clay remained, the rest having disappeared by decomposition. Of these piles (four oak, three birch, and one ash), some were round and some rectangular, and nearly all more or less pointed at the lower extremity. The exceptions were blunt and rested on some fragments of granite stones. One of the piles, which measured six inches broad, and two and three-quarter inches thick, contained four round holes, in one of which a portion of a spar still remained.
Having satisfied himself as to the condition of this portion of the mound already exposed, Dr. Hartmann got permission from the proprietor to sink a shaft into the undisturbed portion underneath. The superficial area of this shaft was 12 feet long and 9 broad, and it was excavated until the sea-sand was reached, at a depth of 11½ feet—i.e. about 21 feet from the surface of the mound.
Continuing now our inspection of this section (the upper portion of which I have already detailed) the following layers were successively passed through:—
| 6. | Clay earth continued | 1½ ft. |
| 7. | Packwerk (No. 2) | 1 " |
| 8. | Blackish clayey stuff (dunkle Kleierde) | 1 " |
| 9. | Light clay (containing the stumps of a second series of piles, four | |
| in number, and from three to five and a half inches thick) | 1 " | |
| 10. | Packwerk (No. 3) | 3 " |
| 11. | Whitish clay, mixed with twigs, branches, reeds, etc. | 2 " |
| 12. | A layer of cowdung (Grüngelblicher fester Kuhdünger) | 2 " |
| 13. | Sea sand (Meeressand) |
The two Packwerke here encountered are stated to be similar to the first, and the relics are also much of the same character. The under portion of both is described as being made up of twigs of oak, birch, and hazel, very much birch-bark, worked bits of wood, wooden handles of tools, burnt faggots, débris of marsh plants (Schilf, Binsen, und Samen von Polygonum), small bundles of bast and other fibres of fine roots, shells of hazel-nuts, fragments of pottery (six pounds), lumps of iron slag (five pounds), broken bones (sixteen pounds), charcoal, a piece of redstone, and the shells of some edible molluscs (Helix fruticum and Strigella, and Cardium edule).
Among the relics to be noted are a spindle-whorl, an iron buckle, and a bit of leather.
Of special interest is a third series of piles, which he describes as terminating in the sea-sand underneath all. These piles were five in number, four oak and one birch, 2 to 5½ inches in thickness, and 18 to 33 inches in length. They were placed in a zig-zag fashion about 1½ foot apart, and traced through the layer of "Kuhdünger" to the "Packwerk," where they became so rotten as to be no longer recognised. One of them had also a hole, which still retained portion of a projecting spar.
Our investigator made observations, but of a much more limited character, on nine other Wurthen, and in all of them he found the "Packwerk" to be a special feature in their structure.
Such is an epitome of the facts on which Dr. Hartmann bases his opinion that not only the Wurthen, but also the neighbouring Warfen and Terpen, were constructed like the fascine islands of prehistoric Switzerland, and the Scottish and Irish crannogs. The idea of pile-buildings can scarcely be entertained by him, and he stoutly combats Pigorini's opinions in regard to the Terpen of West Friesland.
The Fahrstedter Wurth, according to Hartmann, consisted of an original mound some seven feet high, to which on two subsequent occasions additions were made. The initiatory process of its construction was to form a basis of Kuhdünger two feet in thickness. Over this clay and rubbish were placed, to the extent of other two feet; and then came the fascine structures, which raised the mound other three feet. To keep the mass together, piles were driven here and there down to the sandy bottom. But the inhabitants soon found that this was too low to shelter them from the waves and floods, so they constructed an addition to their mound, which raised its surface to ten feet. But this was not enough, and so a third addition was made, which added six feet more to the mound. At this height its surface would be about twenty feet above the medium sea level (Normal Null), and at this height Dr. Hartmann concludes that cottages would be quite secure, as the highest tides on record—viz. 4th February, 1825, reached only 12 feet 4 inches above the medium sea level, a result which would leave a considerable margin for the Fahrstedter Wurth. Of course, the tides never reach it now, as it is protected by the sea-dykes, the first of which was constructed in the middle of the twelfth century.
Very little reflection shows the inherent improbability of Dr. Hartmann's theory. Where could the primitive builders get such a quantity of "Kuhdünger" to start with? If the "Packwerk" was constructed as a solid mass, how could its under portions be so prolific of such varied relics, and other odds and ends of human occupancy? Moreover, the disproportion between the original and final height of the mound is incompatible with the supposition that the successive increases were merely additions entailed by unforeseen circumstances, such as an unusual storm. The three platforms with their corresponding series of upright piles, the stratified assortment of the structural materials, and the position of the relics and débris of its inhabitants scattered throughout the entire mound, are, in my opinion, inexplicable on any other hypothesis than that we have here the remains of pile-dwellings, successively erected one above the other, precisely similar to the terremare already described. The more probable modus operandi was to construct in the first place a circumscribing dyke of mud, varying in size according to the number of the tribe or family, behind which the cottages were built on platforms supported on piles. When the under spaces became filled up with the accumulated débris of men and cattle, and all the other odds and ends of continued occupancy, the process was repeated again and again, until the whole enclosed area, in the course of some centuries, became a flattish mound or island within the limits of the tidal shore.
