6. Five peculiar objects of copper, like awls (Nos. 6 and 8). 7. Seven objects like daggers, lance-heads, or knives, rudely hammered, are also supposed to be of pure copper (Nos. 10 and 11). The winged celt and the larger of the two swords are not noticed in either of the reports of the various investigations, but I am assured they form part of the same find; and, in corroboration of this, I find they are included in a photograph issued by the authorities of the Museum, purporting to be a representation of all the metal objects from the Pfahlbauten. [Illustration: Fig. 45.--LAIBACH. Nos. 14 and 15 = ¼, and the rest = ½ real size.] _Objects of Wood._--A canoe 15½ feet long and 2½ feet wide was pointed at both ends. Also a toy canoe. Fragments of a few dishes, such as a large plate, a spoon of yew wood, and some bowls--one of which is scooped out of a large round natural protuberance of a tree. A few elongated pebbles rolled in birch bark. Portions of bast ropes, and some coils of very fine carbonised linen threads. Two remarkable machines ("Biberfälle") (=Fig. 46=), each constructed out of one solid piece of wood, and having two movable valves in the centre worked by projecting pivots resting loosely in corresponding holes in the machine. These valves are freely movable when pushed upwards, but this motion is arrested just a little short of the perpendicular by the slanting shape of their posterior edges, so that, when left to themselves, they always fall together, and never backwards. The one here represented is in a very perfect state of preservation; and the other, though now in a fragmentary condition, clearly shows that in its structure it was precisely similar to the former. These peculiar implements, though found at a little distance, are considered of contemporary date with the lake-dwelling remains, as they were in the same archæological stratum, and about the same depth in the peat. The one here figured is made of oak, and measures 32 inches long, 12 inches broad, and 4 inches deep. The aperture, when the valves are open, measures 9 by 5 inches. The most recent opinion as to the use of these machines is that they were beaver traps--an opinion that derives much probability from the extraordinary number of the skeletons of this animal which have been found among the food-refuse of the inhabitants of this lake-dwelling.
