_Industrial Implements and Ornaments._--The stone hatchets are exceedingly well-made, and appear to have been partly sawn from water-worn boulders of serpentine and hornstone. None were of _nephrite_ or _jadeite_; a few of horn have been noted (=Fig. 185=, No. 15). The bronze hatchets (=Fig. 4=, Nos. 16, 20, and 25) were numerous, the greatest number having four wings and sometimes a loop at the side; the direction of the cutting edge is generally at right angles to that of the wings, but in a few instances parallel to it (as in No. 16); at the top of the hatchet there is a hole or small recess. Of the flat kind there were a few, one of which is here figured (No. 25). Two small ones are of copper (=Fig. 3=, No. 17). The knives are mostly ornamented with running patterns or circles or semicircles in dots or lines, and the blades are all more or less curved (=Fig. 4=, Nos. 11 to 15); the handles were sometimes solid and of a piece with the blade, but more frequently they were of horn or wood, and attached by tangs or rivets. It is rather remarkable that amongst the large number of knives collected at Wollishofen there is not one of the socketed kind, which, as we shall afterwards see, are so frequently met with in Lake Bourget and some stations in western Switzerland. Some sickles of the usual type, fish-hooks, and a few of the socketed razor knives. Of bronze hammers there are six, all of which are socketed and either round or rectangular in shape (=Fig. 4=, Nos. 8 and 18). The round one, No. 8, is ornamented with a series of circular grooves, and has a socket 1¾ inches deep; it weighs 490 grs. [Illustration: Fig. 3.--WOLLISHOFEN.
