In the efforts which young Franklin made to improve his mind, while in his brother's office, he did not devote his time to mere reading, but applied himself vigorously to _study_. He was deficient, he thought, in a knowledge of figures, and so he procured an arithmetic, of his own accord, and went through it himself, with very little or no assistance. By proceeding very slowly and carefully in this work, leaving nothing behind that he did not fully understand, he so smoothed his own way as to go through the whole with very little embarrassment or difficulty. He also studied a book of English grammar. The book contained, moreover, brief treatises on Logic and Rhetoric, which were inserted at the end by way of appendix. These treatises Franklin studied too with great care. In a word, the time which he devoted to books was spent, not in seeking amusement, but in acquiring solid and substantial knowledge. [Illustration] Notwithstanding these advantages, however, Benjamin did not lead a very happy life as his brother's apprentice. He found his brother a very passionate man and he was often used very roughly by him. Finally after the lapse of four or five years, during which various difficulties occurred which can not here be fully narrated, young Benjamin determined to run away, and seek his fortune in New York. In writing the history of his life, Franklin acknowledges that he was very censurable for taking such a step, and that in the disputes which had occurred between him and his brother, he himself was much in fault, having often needlessly irritated his brother by his saucy and provoking behavior. He, however, determined to go, and a young friend of his, named Collins, a boy of about his own age, helped him form and execute the plan of his escape. [Illustration] The plan which they formed was for Benjamin to take passage secretly, in a New York sloop, which was then in Boston and about ready to sail. The boys made up a false story to tell the captain of the sloop in order to induce him to take Benjamin on board. Benjamin sold his books and such other little property as he possessed, to raise money, and at length, when the time arrived he went on board the sloop in a very private manner, and concealed himself there. The captain of the sloop undoubtedly did wrong in taking such a boy away in this manner. He knew that Franklin was running away from home, though he was deceived by Collins's story in respect to the cause of his flight. The vessel soon sailed, with Franklin on board. The wind was fair and she had a very prosperous passage. In three days which was by no means a long time for such a voyage, she reached New York, and Benjamin landed safely. [Illustration] He found himself, however, when landed, in a very forlorn and friendless condition. He knew no one, he was provided, of course, with no letters of introduction or recommendation, and he had very little money.
