doomed at last to wake a lexicographer.  I soon found that it is too late to look for instruments, when the work calls for execution, and that whatever abilities I had brought to my task, with those I must finally perform it.  To deliberate whenever I doubted, to inquire whenever I was ignorant, would have protracted the undertaking without end, and, perhaps, without much improvement; for I did not find by my first experiments, that what I had not of my own was easily to be obtained:  I saw that one inquiry only gave occasion to another, that book referred to book, that to search was not always to find, and to find was not always to be informed; and that thus to pursue perfection, was, like the first inhabitants of Arcadia, to chase the sun, which, when they had reached the hill where he seemed to rest, was still beheld at the same distance from them.

I then contracted my design, determining to confide in myself, and no longer to solicit auxiliaries which produced more incumbrance than assistance; by this I obtained at least one advantage, that I set limits to my work, which would in time be ended, though not completed.

Despondency has never so far prevailed as to depress me to negligence; some faults will at last appear to be the effects of anxious diligence and persevering activity.  The nice and subtle ramifications of meaning were not easily avoided by a mind intent upon accuracy, and convinced of the necessity of disentangling combinations, and separating similitudes.  Many of the distinctions which to common readers appear useless and idle, will be found real and important by men versed in the school philosophy, without which no dictionary can ever be accurately compiled, or skillfully examined.

Some senses, however, there are, which, though not the same, are yet so nearly allied, that they are often confounded.  Most men think indistinctly, and therefore cannot speak with exactness; and consequently some examples might be indifferently put to either signification:  this uncertainty is not to be imputed to me, who do not form, but register the language; who do not teach men how they should think, but relate how they have hitherto expressed their thoughts.

The imperfect sense of some examples I lamented, but could not remedy, and hope they will be compensated by innumerable passages selected with propriety, and preserved with exactness; some shining with sparks of imagination, and some replete with treasures of wisdom.

The orthography and etymology, though imperfect, are not imperfect for want of care, but because care will not always be successful, and recollection or information come too late for use.

That many terms of art and manufacture are omitted, must be frankly acknowledged; but for this defect I may boldly allege that it is unavoidable; I could not visit caverns to learn the miner’s language, nor take a voyage to perfect my skill in the dialect of navigation, nor visit the warehouses of merchants, and shops of artificers, to gain the names of wares, tools, and operations, of which no mention is found in books; what favorable accident or easy inquiry brought within my reach, has not been neglected; but it had been a hopeless labor to glean up words, by courting living information, and contesting with the sullenness of one, and the roughness of another.
