There was a series of curious incidents that happened during the last part of this year of residence in London that came near changing his career. It was in 1726; he was about twenty years old. He had always loved the water, to be on it and in it, and he became an expert swimmer when he was a lad in Boston town.
He had led a temperate life among the London apprentices, and had kept his physical strength unimpaired. He drank water while they drank beer. They laughed at him, but he was able to carry up stairs a heavier case of type than any of them. They called him the "American water-drinker," but there came a day when he performed a feat that became the admiration of the young London printers. He loved companionship, and had many intimate friends, and among them there was one Wygate, who went swimming with him, probably in the Thames, and whom he taught to swim in two lessons.
One day Wygate invited him to go into the country with him and some of his friends. They had a merry time and returned by water. After they had embarked from Chelsea, a suburb which was then some four and a half miles from St. Paul's Cathedral, Wygate said to him:
"Are you going to swim back to London?"
"Franklin, you are a water boy; let us see how well you can swim."
Franklin knew his strength and skill. He took off his clothing and leaped into the river, and probably performed all the old feats that one can do in the water.
His dexterity delighted the party, but it soon won their applause.
He swam a mile.
"Come on board!" shouted they. "Are you going to swim back to London?"
