rather to develope to the juvenile mind, a plain, easy and pleasing ascent, in the science of practical Arithmetic.

The arrangement of the rules and examples in this work is such as is believed to be the most proper.

Addition and Subtraction of Federal Money are placed immediately after Addition and Subtraction of whole numbers.

Reduction, Multiplication and Division of Federal Money, with simple and concise rules for finding the cost of goods, &c. when the price is an aliquot or even part of a dollar, are placed immediately after Division of whole numbers.

In Reduction Ascending and Descending, the answers to the questions are not set down, as they alternately prove each other.

Fractions, Vulgar and Decimal, have received that attention which their importance demands; being simplified and illustrated in such a manner as to render the study of them pleasing and interesting to the pupil.

In Simple Interest several short rules are given. Also explanatory observations, and remarks on casting Interest on notes, bonds, &c. where endorsements have been made.

The rule called Practice is omitted, except so much as is now necessary in business.

That part of the rule formerly called "Tare and Tret" which relates to trett, cloff, and suttle, is omitted, it being entirely obsolete.

A short demonstration of the Square and Cube Roots is given; and the rules for working Arithmetical and Geometrical Progression, will be found very plain and concise.

After going through the various rules, a collection of useful and entertaining questions is given for exercise.

The Appendix contains a variety of useful Problems in Mensuration, &c. Also a concise method of BOOK-KEEPING, adapted to the Business of Farmers, Mechanics, &c.

Some of the late writers on Arithmetic, have wholly expunged the old currency of Sterling Money; but considering the increasing facilities to commerce, and the contiguity of these States to the British dominions; the Authors have thought proper to retain enough of Sterling Money, to show its

use and nature.

Signs. A cross with one line perpendicular and the other horizontal, is the sign of addition. It shows that the numbers between which it is placed added together. It is sometimes read plus, which is a Latin word signifying more. It also denotes a remainder after division.

Two horizontal parallel lines, are the sign of equality. It signifies that the number before it is equal to the number after it. Thus, 100 cents 1 dollar; read, 100 cents are

equal to 1 dollar. 5+7=12; read 5 and 7 added togeth

Sign. A short horizontal line is the sign of subtraction; it is usually read minus, which is a Latin word signifying less. It shows that the number after it is to be taken from the number before it; thus, 6-2=4, read 6 less 2 is equal to 4, or 2 subtracted from 6 leaves 4.
