His deep breathing , which had sounded like groans , alone served to attract attention to his location . In a little while Washington was all right save for a slight weakness . Captain Henderson made him go to his bunk , and ordered him to remain there until morning . During the excitement over Washington 's mishap all thought of steering the ship had been forgotten , and when Mr. Henderson went to the conning tower about five o'clock he found that the _ Porpoise _ was several points off her course and was headed to the east instead of to the south . How many miles out of her way the craft had steamed could only be guessed , but as she had been going wrong for nearly an hour , it must be quite a few the inventor calculated . However , he said , no great harm had been done . Even this slight accident would not have happened had not Bill , who was in the conning tower steering , forgotten to put the automatic device in operation when he left the wheel to join in the search for Washington .
