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).
