About four o'clock
At three o'clock Mr. Gale and Andy started from the boathouse , and again Andy became a teacher . The young man was a good rower , but Andy was able to give him some points . Sometimes they sat idle and let the boat float at will . About four o'clock Conrad came down for his usual afternoon row . He was surprised and not altogether pleased at meeting Andy and his companion . `` Why are you not hoeing potatoes ? '' he asked .
