PREFACE TO ROLT’S DICTIONARY[1].

No expectation is more fallacious than that which authors form of the reception which their labours will find among mankind.  Scarcely any man publishes a book, whatever it be, without believing that he has caught the moment when the publick attention is vacant to his call, and the world is disposed, in a particular manner, to learn the art which he undertakes to teach.

The writers of this volume are not so far exempt from epidemical prejudices, but that they, likewise, please themselves with imagining that they have reserved their labours to a propitious conjuncture, and that this is the proper time for the publication of a dictionary of commerce.

The predictions of an author are very far from infallibility; but, in justification of some degree of confidence, it may be properly observed, that there was never, from the earliest ages, a time in which trade so much engaged the attention of mankind, or commercial gain was sought with such general emulation.  Nations which have hitherto cultivated no art but that of war, nor conceived any means of increasing riches but by plunder, are awakened to more inoffensive industry.  Those whom the possession of subterraneous treasures have long disposed to accommodate themselves by foreign industry, are at last convinced that idleness never will be rich.  The merchant is now invited to every port; manufactures are established in all cities; and princes, who just can view the sea from some single corner of their dominions, are enlarging harbours, erecting mercantile companies, and preparing to traffick in the remotest countries.

Nor is the form of this work less popular than the subject.  It has lately been the practice of the learned to range knowledge by the alphabet, and publish dictionaries of every kind of literature.  This practice has, perhaps, been carried too far by the force of fashion.  Sciences, in themselves systematical and coherent, are not very properly broken into such fortuitous distributions.  A dictionary of arithmetick or geometry can serve only to confound; but commerce, considered in its whole extent, seems to refuse any other method of arrangement, as it comprises innumerable particulars unconnected with each other, among which there is no reason why any should be first or last, better than is furnished by the letters that compose their names.

We cannot, indeed, boast ourselves the inventors of a scheme so commodious and comprehensive.  The French, among innumerable projects for the promotion of traffick, have taken care to supply their merchants with a Dictionnaire de Commerce, collected with great industry and exactness, but too large for common use, and adapted to their own trade.  This book, as well as others, has been carefully consulted, that our merchants may not be ignorant of any thing known by their enemies or rivals.
