HAVING inspected a new system of Arithmetic entitled the COLUMBIAN ARITHMETICIAN - I am fully satisfied, that it is better calculated than any I have seen, to subserve the instruction of youth, as well as the interest of the merchant and the man of business. In the new method of introducing the knowledge of Fractions, and of Extracting Roots ; and in the frequent exemplifications of the science of Geometry, are many ingenious and useful improvements. I sincerely wish that the industry and talents of the author may find ample reward. by meeting with general patronage and encouragement. Beverly, August 23, 1810.
