Long shots of an explosion in a marble quarry in Italy - half a mountain face comes down.
Full title reads: "Italy. Blowing up a Mountain. Explosion of 20 tons of dynamite releases 40,000 tons of marble."
Shots of mountains with snow on the sides.
Excavation on side of mountain - men are climbing on ladders - their tiny size shows the scale of the workings. They have been placing charges of dynamite. A man at the bottom is waving a flag. One man is climbing down the face of the rock on a rope. This is all taking place in a marble quarry.
The explosion of the dynamite causes a large part of the mountainside to fall down. Clouds of dust and snow rise up.
