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.
