Analogous remains to those in Mercurago have been found in several
other localities, especially in the districts called Pennino near
Borgo-Ticino, and the moor of Gagnano; but the objects were dispersed
or thrown away. A stone celt from this place is figured by Gastaldi
(=Fig. 60=, No. 19).
In the neighbouring moor of Conturabia a group of piles was observed
in the centre of the bog which appears to have belonged to a palafitte
of a later date, as some of the piles were said to have been tipped
with iron. Gastaldi procured one of these piles, and although this
particular one had no iron on it he was convinced that it had been
sharpened by instruments similar to those in use at the present day.
