THE Compiler of this volume is not fond of elaborate prefaces ; he claims no distinguished merit ; and, therefore, briefly states, that he has had recourse to various authors on the subject, to whom he acknowledges himself indebted for a considerable portion of this system : having taken the liberty of extracting such parts as were applicable to his purpose, and of abridging or enlarging as he thought necessary.

To unite as much as possible their several advantages, with a number of recent calculations made in' money of the United States ; to express the different rules with precision in plain language ; to point out a number of short and easy methods of contraction ; to elucidate every rule, by performang at length, from one to three examples ; to give a competent number of suitable questions ; and particularly to adapt the work to the easy and regular instruction of youth, and to the trade and commerce of the United States, has been his great aim.

Any friendly communication which may tend to improve this edition will be thankfuily received by the author, who is conscious of benevolent designs, whatever may be the success of his undertakings.

Bucking bam County, Virginia, May 1, 1810.
