But the Forfarshire is a good modern ship," said Mr Robb. "Nothing can happen to a new ship like this. Listen to those fine strong engines!' Daniel looked down at the big paddle wheel on the side of the ship. It went round and round, down under the white water, and up again under the water, and up. Then he looked up at the black smoke which came from the Forfarshire's funnel. Yes,' he said. "They're good, strong engines.' But he was not really sure. He was an engineer, so he knew about engines. Sometimes the Forfarshire's engines made strange noises, and the paddle wheels went round slowly. Then there was a crash, and they went quickly again. Daniel was not happy. A sea bird flew low across the white tops of the big grey waves. Daniel watched it, and felt wind and rain on his face. Then a door opened behind him, and a woman screamed. Simon, come back! Come back at once!' Daniel looked behind him, and saw a small boy. He was running across the deck. He was only three or four years old, and the wind was much too strong for him. He fell over on the deck and began to cry. Then another big wave hit the side of the ship. The white water came over the side and carried the boy along the deck.
