Ralph sprang down the ladder, and ran along the deck. He was absent for some time, but soon appeared with two men. "Come on," said Ralph, as he ascended the ladder. The men hesitated for a moment, and followed, as an officer appeared and invited them to come up. CHAPTER II THE TORPEDOED SHIP During the next hour or more every field glass on board ship was put into use, and many were the weary arms that used them until the luncheon hour arrived at one o'clock. The captain, knowing how trying the constant watching must be to civilians who are not used to this work, appointed two watches, so they might relieve each other every hour. The boys went to the dining room, and as Mr. Elton and his family sat at the captain's table, the latter took occasion during the meal to refer to Ralph and Alfred's services on the bridge in commendatory terms, which was greatly appreciated by their parents. "I am curious to know," said Ralph, "what the officer meant when he said 'two points to starboard.'" "That is explained in this way," replied the captain. "The compass is divided into thirty-two points, or eight points in each quadrant." "I remember you spoke about a quadrant when we were on the bridge. What is a quadrant?" asked Alfred. "I should have said, in the beginning, that the compass is divided into four parts, one line running, we will say, east and west, and the other line north and south. In that way there are four cardinal points. You will understand, therefore, that from the north cardinal point to the east cardinal point, which represents one quadrant, are eight points, and so on, from the cardinal point east to south, are eight more points," responded the captain. "Then when the officer said 'two points to starboard,' did he mean two points from one of the cardinal points?" asked Ralph. "No, he had reference to two points from the line ahead, or for the time being, he took the line upon which we were traveling, as one of the cardinal lines, and when he said two points he described a line which was just one-fourth of the distance around the circle or quadrant to the east," answered the captain. "Then we might say that the keel of the ship is one of the cardinal lines, and the bridge, which runs across the ship is the other line?" asked Alfred. "That is a very homely and plain way of putting it," replied the captain. An hour thereafter, while the boys were on the bridge, they noticed the first signs of excitement on the part of the officers. A message had been handed the captain a few moments before. Of course, all were curious to know the news it contained, but no one seemed to be bold enough to ask any questions. [Illustration: _The Points of the Compass_] As the second watch appeared at the bridge the boys descended and rejoined their parents. A voice was heard outside summoning the passengers on deck. They were ranged along the deck house, and the second officer appeared.
