Rock is blasted from a quarry in the stone valleys of Caprona, Italy.
Titles read: "BANG! A Quarry Outburst."
In the stone valleys of Caprona (sp?) we see men carrying boxes about a quarry. Dynamite is wired to the rocks as men shout warnings to each other of the imminent blast. A man blows a horn to give the final warning then the dynamite is detonated and a large explosion blasts huge slabs of rock from the quarry.
Note: possibly Caproni?
