Hitherto there was little or nothing done to the Grosser Hafner, and the "Haumessergrund" at Wollishofen, and so the surmises of Dr. Keller regarding them might have died with him, had it not been for the extraordinary exertions of the people of Zürich to have their beautiful environments made still more attractive by art. These extensive alterations, begun some six years ago, and scarcely yet completed, have so entirely changed the aspect of the shore in the immediate neighbourhood of the outlet, that visitors whose recollection of the town dates farther back than these transformations, will hardly recognise the locality. A splendid bridge now spans the opening of the Limmat, and on both sides of it are elegant promenades, gardens, and ornamental quays, which occupy what was formerly part of the lake. The filling up of such a great area of lake-bottom involved the use of dredgers, which, with revolving buckets, raised stuff from the most convenient shallows along the shore, and having dropped it into boats, it was then transported to its final destination. Among the localities selected for these operations were the Grosser Hafner and the outskirts of the Bauschanze. The rich loamy deposits of the Haumessergrund at Wollishofen were also found suitable for mixing with the gravel and for forming a good soil for the floral and horticultural gardens which now form such a conspicuous ornament to the fashionable walks along the northern shore of the lake. [Illustration: Fig. 2.--BAUSCHANZE (13, 14, and 21 to 23); KLEINER HAFNER (1 to 12, and 15 to 17), and GROSSER HAFNER. All ⅓ real size except 13 and 14.] The Grosser Hafner[1] supplied a wonderful medley of antiquarian objects, apparently of all ages--stone hatchets (one of which was 10 inches long), horn handles, bone implements, etc. Among bronze objects were: hatchets of the winged type, chisels, sickles, knives some ornamented with half-circles, points, and lines (=Fig. 2=, Nos. 30 and 35); pins with large heads, oval or round, and sometimes perforated and variously ornamented (Nos. 24, 25, and 26); arm-rings, both closed and open, and ornamented with engraved lines, dots, etc. (Nos. 18 and 28); a few spirals (No. 34), small rings and pendants (Nos. 19 and 27); two solid rings attached by a band (No. 29); a group of four rings--one being larger, on which the other three were hung (No. 20); a pin-like object, 15½ inches long, with a handle like that of a sword (No. 32); lance-heads, some of which were ornamented; a few small beads of amber. Among the fragments of pottery were two vessels complete with round bases (No. 31), and part of a moon-shaped crescent, rudely ornamented with depressions like finger-marks. Here, again, as in the Kleiner Hafner, objects apparently of a later date were found, among which were Roman tiles, pottery of the kind known as _terra sigillata_, and an iron spear-head; also upwards of 16 coins of the time of Augustus, Tiberias and Vespasian.
