The business done over Offut's counter gave his clerk frequent intervals of rest, so that, if so inclined, an abundance of time for study was always at his disposal. Lincoln had long before realized the deficiencies of his education, and resolved, now that the conditions were favorable, to atone for early neglect by a course of study. Nothing was more apparent to him than his limited knowledge of language, and the proper way of expressing his ideas. Moreover, it may be said that he appreciated his inefficiency in a rhetorical sense, and therefore determined to overcome all these obstacles by mastering the intricacies of grammatical construction. Acting on the advice of Mentor Graham he hunted up one Vaner, who was the reputed owner of Kirkham's Grammar, and after a walk of several miles returned to the store with the coveted volume under his arm. With zealous perseverance he at once applied himself to the book. Sometimes he would stretch out at full length on the counter, his head propped up on a stack of calico prints, studying it; or he would steal away to the shade of some inviting tree, and there spend hours ar a time in a determined effort to fix in his mind the arbitrary rule that "adverbs qualify verbs, adjectives, and other adverbs." From the vapidity of grammar it was now and then a great relaxation to turn to the more agreeable subject of mathematics; and he might often have been seen lying face downwards, stretched out over six feet of grass, figuring out on scraps of paper some problem given for solution by a quizzical store lounger, or endeavoring to prove that, "multiplying the denominator of a fraction divides it, while dividing the denominator multiplies it." Rather a poor prospect one is forced to admit for a successful man of business.
