Article Title and/or Image Caption (Dublin Core): Now Comes the Sea Tank. Did the Italians blow up the Austrian dreadnought in Pola with an American wheeled submarine?; Caption 1: The divers are cleaning away the mines. They leave and enter the submarine by a door, just as they would a house. What keeps the water out of the boat? Just air, but at such a pressure that it pushes the water back. Wheels enable the boat to roll on the ocean bed
Caption 2: This wheeled submarine of the Argonaut type was sold to Russia when at war with Japan; Caption 3 : The air pressure on the inside prevents the water form entering the hold when the drap door on the bottom is opened for the diver
