I wondered how the captain would supply our room with new breathable air. Would he create air through a chemical method, or would he simly go to the surface of the water again for new supplies, like a whale. I was thinking about this matter when I felt a strong wind of new breathable air come into the room. I then realized that we had come to the surface of the water. I soon discovered that the air was coining into the room through a pipe in the wall. I has discovered the mystery of the submarine's air supply. At that moment, Ned and Conseil were waking from their deep sleep.
