[Footnote 9: "On one of these days I was, to my surprise, sent for by a great man I knew only by name, Sir William Wyndham. He had heard of my swimming from Chelsea to Blackfriars and of my teaching Wygate and another young man to swim in a few hours. He had two sons about to set out on their travels. He wished to have them first taught swimming, and proposed to gratify me handsomely if I would teach them. They were not yet come to town, and my stay was uncertain, so I could not undertake it. But from the incident I thought it likely that if I were to remain in England and opened a swimming-school I might get a good deal of money. And it struck me so strongly that had the overture been made me sooner, probably I should not so soon have returned to America."--Autobiography, Vol. I. p. 66.] Mr. Denham, his companion of voyage, had decided to return to Philadelphia, and open an extensive store. He offered Franklin two hundred and fifty dollars a year as book-keeper. Though this was less than the sum Franklin was then earning, as compositor, there were prospects of his advancement. This consideration, in addition to his desire to escape from London, led him to accept the offer. He was now twenty years of age. It does not appear that he had thus far formed any deliberate plan for his life's work. He floated along as the current of events drifted him. On the twenty-first of July, 1726, Franklin embarked on board the ship Berkshire for Philadelphia. He had been absent from America but little more than a year and a half. During this time he had not increased his fortune, for he had spent his money as fast as he had earned it. After a voyage of eighty days, the ship cast anchor before Philadelphia. At that time ships were often from three to seven months effecting the passage across the Atlantic. As usual Franklin kept a diary punctually during his long voyage. Its pages were replete with pithy remarks of wit and wisdom. He was very fond of a game of checkers, and in that amusement beguiled many weary hours. We find the following striking comments upon the diversion in his journal: "It is a game I much delight in. But it requires a clear head and undisturbed. The persons playing, if they would play well, ought not much to regard the _consequences_ of the game; for that diverts and withdraws the mind from the game itself, and makes the player liable to make many false, open moves. I will venture to lay it down for an infallible rule that if two persons equal in judgment, play for a considerable sum, he that loves money most, shall lose. His anxiety for the success of the game confounds him. Courage is almost as requisite for the good conduct of this game as in a real battle; for if the player imagines himself opposed by one that is much his superior in skill, his mind is so intent on the defensive part, that an advantage passes unobserved."
