His first work was a _Philosophical and Practical English Grammar_, printed in 1807. It was in many respects original, acute, and excellently fitted for the purposes of instruction. It was, however, only one of the studies for his subsequent and far more important performance. For more than twenty years he had been a close student of the elements and sources of the English language; he had gradually, as his various occupations permitted, accumulated and arranged materials for its exposition, and he now felt himself at liberty to forego all other pursuits and ambitions to devote himself for the remainder of his life to the great labors which have made his name so honorably eminent in the history of the intellectual advances of his country and of the Saxon family. The preparation of a Dictionary, under any circumstances, must be regarded as a very formidable task, involving even for an enthusiast the most dry and wearying researches, unenlivened by any of the pleasing excitements which vary the monotony and relieve the tedium of ordinary literary pursuits. Mr. Webster from the beginning had a just conception of the duties and difficulties before him; he was assured that no superficial study or careless execution would command or in any degree deserve approval, in one who followed in the track of Johnson. He was not disposed to make the work of that great man a basis for his own; to be simply an editor, whose duties should be fulfilled by additions of the new words and new definitions introduced in seventy years; he determined to make a new and altogether original work; to study the English language in the writings of its most distinguished authors, to inquire into its actual usage in conversation and public discourse, not by loosely gathered and ill arranged groups of synonymes, but by a clear and precise statement of meanings, illustrated, whenever it should be necessary, by various instances. In this work, Johnson had made a beginning; he first conceived the plan of defining by descriptions, instead of synonymes; and he had introduced into his larger dictionary quotations from the best authors. But his work, valuable as it was, was imperfect, even in regard to the words current in his time, and which he succeeded in collecting. But, if Johnson had perfectly accomplished his design, the lapse of seventy years of such extraordinary and various activity in every department of human action and aspiration, would have rendered a New Dictionary indispensable. New sciences and arts had been discovered, which, in their manifold applications to industry, had changed or wonderfully augmented the technology and common speech of every class and description of workers. New experiments had been made in governments; new institutions had been introduced; literature had assumed new forms; and speculation, with perfect freedom and gigantic force, had forged new weapons for its new endeavors.
