its execution in a manner as strictly mechanical as if he had been rectifying a smoky chimney or devising a helpful pair of glasses for his defective eyesight. The virtues were classified by him under thirteen heads: Temperance, Silence, Order, Resolution, Frugality, Industry, Sincerity and Humility. These terms were all tabulated by him in a little pocketbook kept for that especial purpose, and to each virtue the close attention of a week was successively given by him. If an offence was committed by him on a certain day, it was entered by a little black mark under that date opposite the affronted virtue. The object was to so concentrate his vigilance upon each virtue in turn and to so strength his capacity to resist every temptation to violate it as to finally render its practice habiutal and instinctive. The plan in spirit was not unlike the system of prudential algebra to which he told Joseph Priestley, many years afterwards, that he resorted when his judgment was in a state of uncertainty about some problem. In one column he would jot down on a piece of paper all the pros of the case, and in another all the cons, and then, by appraising the relative value of each pro and con set down before his eye, and cancelling equivalent considerations, decide upon which side the preponderance of the argument lay. Even Franklin himself admits that his plan for making an automatic machine of virtue did not work in every respect. Order he experienced extreme difficulty in acquiring. Indeed, this virtue was so much against his grain that he felt inclined to content himself with only a partial measure of fidelity to it, like the man, he said in the Autobiography, who, though at first desirous of having his whole ax bright, grew so tired of turning the grindstone on which it was being polished that when the smith, who was holding it, remarked that it was only speckled, and asked him to turn on, he replied, "But I think I like a speckled"
